Stm32cube framework, Not getting uart output on VCP on a Mac

[mleo]

I am having the same problem as this:

Uart Transmit works in STM32CubeIDE but not in PlatformIO (I use the same code)

With the function HAL_UART_Transmit I send a string to the console. The problem is that the whole thing works in STMCubeID but not on PlatformIO. When I run the same code on Platform IO, I get nothing on the Consol. I think it has something to do with the clock. I measured the 100ms delay with a logic analyzer. On the STM32Cube I measured 107ms and on Platform IO 102ms. platformio.ini platform = ststm32 board = nucleo_f303k8 framework = stm32cube board_build.f_cpu = 8000000L main Un…

I’m using a nucleo-l432kc. I posted the .ioc and main.c to the ST community forum. A member compiled and ran the code on a PC using STM32CubeIDE. The PC com port received the “Hello World” message. My Mac compiling in Platformio and running screen as a terminal emulator gets nothing.

Has this been resolved? Is there a “monitor” setting in the platformio.ini I need to set? Something else?

BTW, I made a simple sketch and used the arduino framework. Serial.println(“Hello World”) works fine.

OK,
Changing the toolchain/IDE environment in STMCubeMX from EWARM ( the default ) to STMCubeIDE fixed the problem.
