    • RE: Custom 1HCL HW/FW bootloader issues

      @dc42
      Just to put a bow on this (Merry Xmas 🙂 ). I got it all working. It took another board rev as I had a couple hw hiccups. This included to swapping the MAX3051 to the TJA1441A CAN xcvr per David's #2 note. Any rate, brand new mcu flashed the bootloader first go. I had to first set the fuses as I listed above. The default fuses had several differences, but I didn't note them.

      Also, all gpio, motor drivers and accelerometer are working as intended. interested. The '1HCL' is config'd as;
      x3 step/dir drives
      x2 med current outputs
      x4 inputs, 24v tol
      x1 lis3dH. I have the W on hand but just wanted to get the original circuit working first

      I attached the final config with all the extraneous comments deleted in case anyone is interested.

    • RE: Duet Openpnp Head

      @dc42
      Your Duet solution sounds interesting, but bus loading sounds like a potential issue and I don't have the know how to analyze any performance hits to the CAN bus. I do appreciate your answer though as it reinforces my confidence in my work around.

      The rationale for vacuum sensing to determine whether a part was successfully 'picked' or not. Vacuum sensing is not mandatory, and I have been running without it for sometime, but it can substantially increase machine efficiency. Efficiency is increased by not allowing the machine to run every potential pick to the vision system 100's mm away.

      As you note, Openpnp doesn't necc need to know the actual vacuum value, but whether a part is 'on' or 'off' the nozzle. The challenge in qualifying if a part is 'on' vs 'off' include;

      • Different nozzle tips have different vacuum 'on', but part 'off' values
      • Different part packages have different 'on' values for the same tip
      • The vacuum signal in general is very noisy and slow to build to maximum.

      Openpnp has some pretty comprehensive functions to analyze and differentiate vacuum states for all vacuum part/tip parameters. But my machine initially had weak diaphragm pump that was slow and noisy. I couldn't get the Openpnp functions to work consistently in a practical way. I've since upgraded to vacuum ejectors, and I no longer have any of the original control electronics.

      Im all Duet3 now with robust pneumatics, I'm pretty confident I could use Duet3 Temp/analog sensing to leverage the Openpnp functions. But this seems like it will be slow especially given the Duet 4Hz sampling rate. This is a full custom system now and I think a purpose-built vacuum sensor feedback system would be much quicker. I don't want to slow the system by packing dwells into the pick/feed process waiting for a stable Temp reading.

      This is all just speculation. I don't have the sensor circuit designed or in place yet. I have no idea what the sensor hw actual transfer fxn will look like and or if it'll need filering.

      Regardless of the vacuum sensing hw, I like the idea of abstracting the Openpnp fxns and performing them locally on a dedicated vac board mcu. The mcu is updated on the current part/nozzle via Duet3 aux comm and allowed to free run sampling the sensors, only flagging the Duet/Openpnp system via IO_x.in on any state changes.

    • Duet Openpnp Head

      I've built a custom Duet Exp3 board using the Duet SAME5x that handles x3 motors, the limits and the outputs. The only thing missing is x2 vacuum analog sensing and I don't think I'll be able to use the Duet control algorithm as the analog/heat task is only 4Hz. There is also some vac based logic processing that needs to take place and I'd like to keep the Duet focused on digital signals and kinematics.

      My solution is to use a secondary vacuum sensor board with a dedicated non-Duet mcu to monitor sensor levels and that will set digital io on the Duet inputs. Sensor thresholds will be dynamically set via Openpnp/Duet Aux comm via RS485. Openpnp will simply ask the state of the associated Duet input...

      Am I over complicating this? Am I missing a fully native Duet solution?

    • RE: LIS3D using SPI issues

      @dc42 Ah ok, I thought any digital input simply had to be assigned a unique 0-15 Exint. Makes sense now. Ill review the DS and see if I can sort it out.

    • RE: LIS3D using SPI issues

      @dc42 @gloomyandy @oliof

      I got it sorted :). I was suspecting the INT pin irq was not getting called because both of my newly declared io0 and io1 pins aren't getting flagged in OM. I tried setting other gpio as inputs and the first pin I found that the OM would flag I set to the LIS3 INT1 and now everything works;

      /** Doesnt work **//
//constexpr Pin Lis3dhInt1Pin = PortAPin(12);
//{ TcOutput::none,	TccOutput::tcc1_2F,	AdcInput::none,		SercomIo::none,		sercom2cPad0,		4,	nullptr 	}, // PA12

/** Works! **//
constexpr Pin Lis3dhInt1Pin = PortBPin(3);	
{ TcOutput::none,	TccOutput::none,	AdcInput::adc0_15,	SercomIo::sercom5d,	SercomIo::none,		3,	nullptr		},// PB03

      The proof

      Now I just have to sort out what is going in the config.h, with none of my inputs working as I initally set. All the outputs work fine.

      Any rate pleased to announce Duet3Exp SPI works 🙂 Thanks for the help guys!

      I still not getting any data in the accelerometer files. But Im pretty confident in the sam to lis3 spi comm. Heres some screen grabs of the comm. Im not familiar with accelerometers or this chip so I need to review. One thing I do notice is INT1 is staying high. I would assume this should be cleared once the sam reads the data.

      Anyrate heres what I'm seeing;

      Ok, thanks for the info. I'll give testing on the bread board a go now that I have that working. I have 2 diff BOBs that both supposedly support i2C and SPI. I only chose spi on personal preference. If it becomes too difficult to implement Ill revert back i2C.

      1, point taken and thank you for the heads up.
      2, yes this is by design
      3, I presumed as much, thanks for confirming as I was having trouble following the revs to understand the relationship

      I finally got a blank chip flashed and running w the bootloader and able to tie into the Duet CAN system. The issue was improper fuse setting. To fix I simply set the USER_WORD_x fuses as I read from the OE 1HCL chip;

      USER_WORD_0 = 0xFE9AE239 (valid)
USER_WORD_1 = 0xAEECFFB1 (valid)
USER_WORD_2 = 0xFFFFFFFF (valid)

      This is good because I can now debug on the bread board which I can't do in circuit. I proceeded to order my untested circuit because I couldn't get the bootloader to work on the breadboard. I thought this was because the chip carriers got don't have a provision for the bottom solder pad. I assumed that pad was an essential ground that when missing was causing all of my problems. Fortunately not the case.

      Thanks for the help David! 🙂

    • RE: LIS3D using SPI issues

      hmm doesn't appear to be working. I am able to set the command and create the .csv file, but the file stays empty;

      Here is the config setup

      M955 P50.0 I20
;M955 P50.0 C"spi.cs1+spi.cs0" I10 ; configure accelerometer on exp using SPI pins and specify orientation

      Again, this is custom FW on custom HW. I'm fairly confident in the HW. Not so confident in my FW config.
      I have set things for;

      • x3 dumb drivers; all 3 step signals working but dir on driver2 not working, HW correctly ohms out
      • x2 outs; all work
      • x2 io inputs; appear functional but not working as expected. Input changes are not reflected in the OM. I'm sure the HW is wired correctly as setting them as pullup via config '^' pulls them to vddd otherwise, they float.
      • x1 spi for LIS3. under review

I briefly tried the DWC input shaper plugin, but it complains about the machine not being homed. There are no kinematics/limits hooked up at the moment I just want to confirm on the bench the HW/FW are really working. How do I go about this?

    • RE: Custom 1HCL HW/FW bootloader issues

      After transfering the Duet 1HCL chip onto my custom pcb I was able to boot load my custom main FW and it mostly works as expected as an CAN expansion node.

      I still don't know what is going on with the bootlaoder FW not working on the blank chip. After comparing the Boot FW 2.4 to 2.11 I wasn't coming to any conclusions and I impulsively swapped the OE Deut chip out for my blank chip to see if the 2.4 Boot FW would make a difference. Still no worky 😞 I know the custom HW is fine and the Bootloader FW ver doesnt seem to make a difference so it must be the fuses. Before I swapped the mcus the last go I took screen shots at the fuse settings. They appear different, but I dont know what or how to interpret them or if it is imperative that they match exactly.

      Heres a comparison of the blank chip fuse setting on the L and the Duet 1HCL chip on the R. the different values are underscored red. Should I just set them to match? If anyone has any advice on setting the fuses would be greatly appreciated

    • RE: Custom 1HCL HW/FW bootloader issues

      So I got antsy and have some 1HCLs laying around. I pulled the mcu from the OE 1HCL and swapped it into my custom board. The CAN now works and DWC and OM is working. I noticed the Bootloader FW is different than what I was attempting to use.

      218d0c64-30fa-4774-b685-f30f6c18e319-image.png

      I looked up the 2.4 Bootloader and the readme states there is 1HCL specific changes in this the 2.4 ver. I never thought to look past 2.11 as it's the 'latest'. Any rate I'll work on getting my custom main fw on and see how it all goes...

    • Custom 1HCL HW/FW bootloader issues

      I made a custom circuit based on the ATSAME51G19A/1HCL. I have the mcu in circuit and have programmed it with SAME_5x v2.11 with nEDBG programmer in Microchip Studio. The chip was erased, fuses set and memory flashed as outlined in the Duet update bootloader faq. Erasing and flashing the chip went fine as verified in Studio.

      Ive attached the custom board to a 6HC via CAN cycled the power several times and Im still not getting any fw update requests in DWC or seeing any other boards attached in the OM. I put a logic analyzer on the custom board CAN rx line and are getting msgs, but the tx is sitting idle/high. The circuit follows the Duet 1HCL circuit in regard to OSC, CAN, Board type and SWD so I didn't think there is anything to change in the Bootloader FW config.

      I did look at the SAME_5x v2.11 config file and noticed there's a 3-bit binary board type scheme, but no analog board type scheme as the 1HCL appears to use. Anyway, I don't know if that is imperative but can't see any other reason why I can get mcu running with bootloader.

      Schematic of circuit attached, any help is much appreciated

    • M261.2: UART read output findings

      Just an Fyi re the new M260.2/M261.2 commands in RRF 3.6. I was stuck for a couple days trying to leverage the 6HC Aux comm port to get/set parameters of a foc motor and report them back to Openpnp via the Main comm port.

      Im sending/receiving data on the Aux port as;

      M260.2 P1 B{0x52, 0x5A, 0x0D}
G4 10
M261.2 P1 B6

      The expected Rx data on the Main port is simply a byte array;

      {0x5a, 0x65, 0x72, 0x6f,0x3a, 0x5a}

      M261.2 indeed reports the data to the Main comm port, but is prepended with" Received (hex) " and the rx bytes are space seperated; ' ' ;

      2024-11-25 22:38:29.200 GcodeDriver$ReaderThread TRACE:
[GcodeAsyncDriver:COM13] << Received (hex) 5a 65 72 6f 3a 5a

      This needs to be understood, but not explicitly stared in M261.2 if anyone is planning to parse the rx data as one would using regex. For my application the regex

      ^.*( [0-9a-f]{2}){5} (?<Value>[0-9a-f]{2})

      Groups the correct Value for me.

      Any rate the new commands work great now that I understand the output.

    • RE: LIS3D using SPI issues

      @dc42
      SPI success! Before unwinding everything, I took another look at the git repo and spotted LISAccelerometer.cpp had been updated after my other file update. I updated that file and everything compiles for LIS3D on SPI.

      Ill mark this question as solved once I confirm HW function. I have the chip carrier for the SAME5 on order but probably won't rec for a couple weeks. I may just order the PCB regardless as I need the machine back up and running and the accelerometer no critical for its fxn.

/**REMAPPED**/#  define ACCELEROMETER_USES_SPI			(1)				// accelerometer is connected via SPI

      I tried that but still errors. I still plan to unwind everything and go back to I2C

      @dc42
      Hi David, I didn't change the #define SUPPORT_SPI_SENSORS 1, but I did change quite a bit of the file. For the sake of completeness I attached my full config file. I've tried being very explicit of my flagging changes by prefacing changes, eg;

      //**REMAPP**//constexpr size_t MaxPortsPerHeater = 1;     
/**REMAPPED**/constexpr size_t MaxPortsPerHeater = 0;

      I don't expect you to comb thru my full config, but if you do take a look and see anything off it'd be great if you let me know 🙂

      Meantime Ill revert the LIS3DH back to I2. I only made that change as I prefer SPI to I2C. But if SPI is causing probs and hasnt been tested then Ill go back I2C.

      Thanks again

    • LIS3D using SPI issues

      Im reconfiguring 1HCL 3.5FW for a custom board. I want to use the LIS3D on the SPI PA(15-19) of SAME5x , no other peripherals on the SPI bus. Heres part of my .h config;

      #define SUPPORT_SPI_SENSORS		1
//**REMAPP**//# define SUPPORT_I2C_SENSORS	1
/**REMAPPED**/# define SUPPORT_I2C_SENSORS	0
# define SUPPORT_LIS3DH

#if SUPPORT_LIS3DH	
#  define ACCELEROMETER_USES_SPI			(1) // accelerometer is connected via SPI
constexpr Pin Lis3dhCsPin = PortAPin(18);		     // same as encoder CS pin
constexpr Pin Lis3dhInt1Pin = PortAPin(12);		    // same as io1.in

# endif

// Shared SPI (used for interface to encoders, not for temperature sensors)
constexpr uint8_t SspiSercomNumber = 1;
constexpr uint32_t SspiDataInPad = 3;
constexpr Pin SSPIMosiPin = PortAPin(16);
constexpr GpioPinFunction SSPIMosiPinPeriphMode = GpioPinFunction::C;

constexpr Pin SSPISclkPin = PortAPin(17);
constexpr GpioPinFunction SSPISclkPinPeriphMode = GpioPinFunction::C;

constexpr Pin SSPIMisoPin = PortAPin(19);
constexpr GpioPinFunction SSPIMisoPinPeriphMode = GpioPinFunction::C;

      Im getting a bunch of errors

      Any help on clearing this up? Thanks!
