Paneldue 7" with esp32/raspberry pi

@Candy yes, you can use Eclipse IDE to make a custom binary. I suggest you retain the startup code, hardware interface code and libraries from the existing project to save you having to write those parts again.

@dc42 Thanks for the reply. I'll give this a try and get back to you

@Candy Hey I tried using Eclipse IDE. I followed the steps given in the projects folder in github. I installed arm-none-eabi-gcc 10.3-2021.10, eclipse ide for embedded c/c++, edited the PATH in system and eclipse to look for make and arm-none-eabi-gcc. When I build the project, I get the error which I have attached in the photo. Is this an error due to any different versions installed? Have you got this error?

[dc42]

@Candy the gcc version you are using is too old. Try the latest one from https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads.

@dc42 Wow that worked. Thanks for the help

[Candy]

@dc42 That worked great. Right now, I built the project and got the .elf file and converted into .bin file and used Bossa to upload the .bin file. Can you give me a heads up on how to use eclipse for coding the display and where to start as the ide feels totally new to me.

@Candy you'll have to do the programming yourself, but I can give you a general guide to what the existing modules do:

• Function main() in file PanelDueFirmware.cpp contains the initialisation, followed by a forever-loop that's similar in concept to the Arduino loop() function. It checks for data received from the serial port, checks for input from the touch panel, and updated the display as needed
• The Hardware folder contains files and functions that interface to the screen, touch panel, piezo buzzer and serial port. You'll probably want to mostly leave those alone, at least to start with. The SerialIO.cpp file parses received characters as JSON objects because that is the format in which Duets send data to PanelDue.
• The UI folder defines the user interface. Within that, Display.cpp defines a number of types of object that can be displayed, for example buttons and text fields. UserInterface.cpp defines how the user interface responds to received data and to presses on the touch panel.

@dc42 So, in order to display simple text like "Hello" or display an image, will editing just the main() file work? In case I need custom buttons/graphics, I should be editing the UI folder

[dc42]

@Candy yes you could display simple text or images by editing the main() function in PanelDueFirmware.cpp and directly calling functions in the LCD module in the hardware folder.

@dc42 Nice. Thanks for the help. This means a lot
