STM32F103CBT6 - Blue Pill - Support

[rtek1000]

Has anyone successfully tested this library with STM32?

It worked with Arduino Nano, but it didn't work with Blue Pill.

The SPI port signal seems to be working, the ACT LED lights up when the flash drive is inserted, but the library prompts you to insert the flash drive even with the flash drive inserted and the ACT LED lit. ("Attach flash drive first!")

The SPI port has no other devices.

It worked. Seems to be a problem with SPI port remapping. It worked only with the unmapped SPI port, SPI1 on pins PA4, PA5, PA6, PA7. When remapping to PA15, PB3, PB4, PB5 did not work. In both cores for Arduino it worked with SPI1 without remapping. The problem is that these pins are also analog inputs, which I need to use with NTC sensors.

It worked with the SPI1 port remapped to the PB pins, but only using the INT pin. Without the INT pin did not work.
