Panel Due firmware 1.21.2 released

dc42

I have released a minor update to the Panel Due firmware at https://github.com/dc42/PanelDueFirmware/releases/tag/1.21.3 [EDIT: changed link to point to 1.21.3 instead of 1.21.2]. The changes in this release are:

Changed dot clock polarity for supported 5" and 7" TFT panels using SSD1963 controllers. This improves display quality in some cases, especially for 7" panels.
Bug fix: if the Macros button was pressed and a macro subdirectory entered, the macro buttons on the Control page might run incorrect or invalid commands.

See section Testing the board and updating the firmware in https://miscsolutions.wordpress.com/paneldue/ for firmware upgrade instructions.

I noticed on the releases page in the section on which binary to choose, they all recommend the V3 files. Shouldn't the older versions of the hardware be using the V2 binary?

I tried the V3 binary on my V2 hardware and it doesn't come up at all. I have to reflash to a V2 binary for it to work.

Choosing the correct firmware binary

If you have a PanelDue with the controller and TFT panel integrated on a single PCB, choose PanelDue-5.0i-7.0i.bin

Otherwise, if your PanelDue controller board is version 3.0 or 3.0a, choose the binary with -v3- in the name and your TFT panel size at the end

Otherwise, choose the binary with -v3- in the name and your TFT panel size at the end (these binaries work with version 1.0, 1.1 and 2.0 controller boards)

Also just noticed that 1.21.2 doesn't seem to have a release for regular V2-7", only the V2-7c. Neither the V2-7c, nor the V3-7.0 releases will work on my V2-7" board.

Installed PanelDue-5.0i-7.0i.bin on a 7i physical board. Works fine.

Installed during the middle of a long print... unplugged 4-wire, upgraded, etc. When re-installing, print paused!!! Yikes!!!!

Turned out I'd just bumped the filament sensor wire. Plugged it back in, resumed via PanelDue, all is well. Whew!!

Thanks @Phaedrux , I have corrected the text. I will add the missing binary tomorrow.

Firmware Update works!
2 Things to mention:

If you choose german as language, the "Time-left" post is cropped due to its size... Maybe you could just use a different expression to minimize the letters needed?
The buzzing noise if the panel is dimmed is still there is there any way to change the pwm frequency or something else so that the noise will be reduced?

Sorry but I cannot find the version 2 for the 7" panel, is my fault or what?
Tnx

Unfortunately the bug fix for the control page macro buttons in release 1.21.2 was incomplete. Therefore I have withdrawn that release and replaced it with 1.21.3, available at https://github.com/dc42/PanelDueFirmware/releases/tag/1.21.3. My thanks to @mloidl for providing the missing part of the fix.

Can you suggest an alternative expression?

Which TFT panel are you using? I can increase the PWM frequency for the 7" integrated version, but I don't know whether it is safe to do this for the other panels.

Not your fault, it was missing from the 1.21.2 release. I have included it in the 1.21.3 release.

@dc42
I am using a PanelDue 7i (the newest one) Just tried to record the buzzing noise: At first, you hear a click as I dimm the LCD, then the buzzing noise occurs. Then I switch back to full brightness and the noise stops. Do you think increasing PWM-frequency may solve it?
Buzzing noise when dimmed

for the translation:
may you send me the german text as well as the english one? Couldn't find it in the source code... Think this will be the easiest way to get a good result.

@dc42 now got the problem:
Time left: file XXX, filament XXX, layer XXX
Restzeit: Datei XXX, Filament XXX, Schicht XXX

So in german there are 2 more letters than in english. I'd suggest to use just layer instead of Schicht as this is a common expression used in the german speaking community. So the total fixed amount of letters would be the same in german as in english and the expression wouldn't be cropped any more.

All the text is in this file https://github.com/dc42/PanelDueFirmware/blob/master/src/Strings.hpp.

Increasing the PWM frequency to 20kHz would eliminate the buzzing. I have confirmed with the manufacturer that 20kHz is OK for the 7i, so I will increase it in the next release. The odd thing is that my 7i display is virtually silent - I can only just hear it if I put my ear right up to the display or the back of the PCB.

@dc42 so I would suggest to use "layer" instead of "Schicht". As written above, this is pretty common to use in the german speaking community.

PS - I've just built new PanelDue 7i firmware (1.21.4) with the backlight PWM frequency increased to 20kHz, also I doubled the maximum size of the file lists. You can find it at https://www.dropbox.com/s/zspt57vb1nn0h43/PanelDue-5.0i-7.0i.bin?dl=0.

@dc42

yiha! The noise went away thanks a lot! (think the "no-logo" bin and maybe the cropping problem will be changed later on, but thanks a lot!)

I updated the German text to "Layer" shortly after I posted the link.

The "nologo" version works on my 7i. You can get it here https://www.dropbox.com/s/omy7i2t6tb4b979/PanelDue-5.0i-7.0i-nologo.bin?dl=0.
