Re: [Solved]Error when running the same code on Linux and IDE

Hi Jimmo, I solved the issue already. The issue is the function BSP_LCD_Refresh() needs an interrupt to end its "setting tear on". But in uPython, that interrupt cannot be called. therefore, the issue occurred. The interrupt is EndofRefreshCallBack in stm32l4r9i_discovery_lcd.c Anyway, thanks for yo...

Re: Error when running the same code on Linux and IDE

Hi Jimmo, Remember that MicroPython will use all available RAM for heap+stack. Many of those ST libraries will do things like assuming they can use a particular region directly for a framebuffer. I've read the memory map in STM32L4R9xx datasheet DS12023 https://drive.google.com/file/d/1SXgBwglsO_yOf...

Re: Error when running the same code on Linux and IDE

Hi Jimmo, Yes surely i run the code on STM32L4R9I Discovery. With IDE i mean that I compiled and build the code, then load it to the board and run. And by Linux, I mean that i build LCD module in C language, translate it into MicroPython modules, compile the code. An then I write MicroPython command...

Re: [Error] Linux: when including a function from BSP Disocvery library

Hi Jimmo, Thanks for your response. My team figured out the error and solved it already. On IDE (we used STM32CubeIDE), when we configure the board and the project, there is a file called stm32l4xx_hal_conf.h created by the template stm32l4xx_hal_conf_template.h in Inc of the Hal library. As far as ...

Re: Display PYFLASH of STM32L4R9IDISC in Ubuntu/Window

If you had non-micropython firmware flashed on the board before flashing micropython, then you should do a mass erase and then flash micropython. Or factory reset the filesystem as documented here: http://docs.micropython.org/en/latest/wipy/tutorial/reset.html#factory-reset-the-filesystem Whwn you ...
