Arduino for STM32

After HardwareSerial(USART2, HALF_DUPLEX_ENABLED);
The TX pin is pulled HIGH (measured with oscilloscope) but it just stays HIGH, although in loop there is a println.
No data is coming out through the port.

So I went ahead and soldered a STM32L072 on a breakout PCB. I can run blinky on any digital pin I choose. I cannot use all the serial ports. Serial.begin works and I can Serial.println on the serial port I use to program the uC, but all the other 4 ports don't work, even after HardwareSerial Serial2...

Hello everyone, I saw that there is a small development board that uses the MCU mentioned in the title, it can be found at the following link: https://hackaday.io/project/161054-thunder-pack Now on the webpage it says that it is supported by the STM32duino core. Could that mean that I could use a ST...

Currently not. I guess the best way would be to add or extend API to be enable the hw flow control Well, can't someone modify the Serial.begin() function of the official STM32 arduino core to accept more input parameters that set HW flow control on or off? And also make it backwards compatible by a...

Is there a more elegant way of enabling hardware flow control than editing a file in the core?
Like the way we can modify clock speed by copying some lines from what cubemx generates into the arduino sketch?

I just edited the file: c:\Users\Razvan\AppData\Local\Arduino15\packages\STM32\hardware\stm32\1.8.0\libraries\SrcWrapper\src\stm32\uart.c i modified line 308 as: huart->Init.HwFlowCtl = UART_HWCONTROL_RTS_CTS; Made a simple arduino sketch with some text printing on Serial2 in loop and hardware flow ...

How can I enable hardware flow control RTS CTS in Arduino using the official ST core? If I configure STM32CubeMx for hardware flow control, in the generated files \src\stm32f1xx_hal_msp.c file, I see that it initializes the RTS CTS pins as output and input together with the RX and TX pins, I'll copy...

Works like a charm. Thank you a thousand!

So I managed to run the MCU at 4MHz by looking into the cubemx generated files and copy-pasting the prescaler values in the stm32duino file: c:\Users\Razvan\AppData\Local\Arduino15\packages\STM32\hardware\stm32\1.8.0\variants\PILL_F103XX\variant.cpp I did this beause I couldn't figure out how to inc...

For 1.8.0 core

This example compiles OK on the 1.8.0 core.
Thank you!
