Arduino for STM32

for this:

Code: Select all

#define USE_STANDARD_SPI_LIBRARY 2

Maybe it helps.

Thank you for your suggestion. I will try it

Or I have missed something in setting up to use other SPI port?

This is the code that I used to switch to other SPI port(frowm ReadWrite example of SDFat library)


#include <SPI.h>
#include "SdFat.h"
#define SD_CS_PIN PB12

// Use second SPI port
SPIClass SPI_3(3);
SdFat sd2(&SPI_3);
File myFile ...

I recommend to use my fork of SdFat .

And get the latest core files from my repo, because I pushed today a commit to solve an issue which is also relevant for SPI and other peripherals.


Hi,
I have tested your forked SDFat and it works but in SPI1 only.

My purpose is to use SD card in other ...

Thank you it is working fine now in 1.8.10

Thanks. I will try this

Thank you

Hi there guys,
I'm trying to use the Sdfat library by greiman ( https://github.com/greiman/SdFat ) but I'm not able to compile it successfully.
I'm compiling the example "SdInfo.ino" from the example folder.

the error is

C:\Users\LAPTOP\Documents\Arduino\libraries\SdFat\src\SpiDriver\SdSpiSTM32 ...

oh..good input I learned something new with you.
Well i dont know how to make a makefile as I have encountered it a lot of times.

Maybe @stevstrong should check this out so it will work on 1.8.10.

Serial1.begin(152000);
tried Serial1.begin(115200); instead?
152000 seemed quite odd a baud rate, but nevertheless, stm32's uart tend to still work with odd baud rates
i actually tried successfully to connect esp8266 at 74880 baud on stm32f103

to dig into the bottom of it one may need a ...

try a debug?
or did you try commenting the serialX to see where the 'hang' occurs?


Thanks for your suggestion :)

What I have tested is,
1. Use only the USB serial (Serial) --> result does not hang
2. Use USB Serial(Serial) and added Serial1 --> result does hang
3. I just added all the serial ...
