Arduino for STM32

I tried to remap the serial2 pins (PA2/PA3) to PD5/PD6 by using afio_remap(AFIO_REMAP_USART2) in my sketch, but it dose not work.

Please help !

Dear All, My project use the ADCTouchSensorSTM library (https://github.com/arpruss/ADCTouchSensor) with a STM32F103C8T6 board, it works with no problem. But when I upgrade my project to a STM32F103RCT6 board, there is error for the ADCTouchSensorSTM library during compilation : ---------------------...

I corrected to enableDebugPorts() and compilation OK. But SD is failed. I tried using other pins as CS (PA11 or PA12 or PB8), for example : pinMode(PA11, OUTPUT); afio_remap(AFIO_REMAP_SPI1); // connections : MOSI= PB5, MISO=PB4, SCK=PB3, CS=PA11 if (!SD.begin(PA11)) { Serial2.println("DC16(0,4...

I added enabledebugPorts() in setup, but during compilation it said : 'enabledebugPorts' was not declared in this scope.

The SPI2 method works ! But the SPI1 remap method do not work. Here are the codes I use : #include <Wire.h> #include <SPI.h> #include <SD.h> void setup() { Serial.begin(57600); Serial.println("Boot ..."); delay(50) ; // using alternate SPI1 pins // CS=PA15, SCK=PB3, MISO=PB4, MOSI=PB5 afio...

Thank you all, I am using the STM32F1/F4 core files (Leaflabs-based core).

I have some working codes based on the standard SD library, changing to another SD library involve to much work and not preferred.

Hi everyone, I use a Generic STM32F103C8T6 to do a project. My project use the standard arduino SD library to read/write data, but the default SPI pins (PA4-PA7) are used for other purpose. It seems that there is another set of SPI pins (PA15,PB3-PB5) that can be used, but I can't found any informat...

Hi everyone,

I have tried and installed several STM32 cores to see which one suite my need.

But I forget what core now I am using !

How do I check out which core and what version I am using ? Thanks you.
