BluePill using Roger USB download process

Please ignore this as I only want to post something but was not allowed for new users …

maxgerhardt · March 4, 2020, 3:53pm

Uh, ok? So what did you want to post about? o_O

creatron · March 4, 2020, 4:50pm

I am sorry I just keep getting the message that I cannot , because I am new and I have 2 links ?..

maxgerhardt · March 4, 2020, 4:53pm

I changed your trust level so it should work now.

creatron · March 4, 2020, 4:56pm

Basically I can program a bluepill with roger 20k program and linux detect a virtual port and dfu. I the use maple as source. I can then download a test program and both UART and LED works, however if I try to use SPI1 I get many errors, change to stm and it complies file , but cannot download. I then change the download to dfu, and it programs, but the virual port disappears and only a dfu is sense in Linux
I want to send all info but cannot

It should be SPI2, not SPI1 , just made a typo error.

maxgerhardt · March 4, 2020, 6:03pm

Seems like a usage error. Your sketch may be written for the STM32Duino core (called “stm32” in PIO) and not the maple core by Roger Clark. The maple board uses core: "maple" while bluepill_f103c8 defaults to stm32:

The SPI class in the Maple core is instantiated by using only the SPI number from 1 to 3. The slave select / NSS pin is then given in the beginTransaction() call.

github.com

rogerclarkmelbourne/Arduino_STM32/blob/0383384f4cc91aadee1501e11bf08dd3e62d9fb9/STM32F1/libraries/SPI/src/SPI.cpp#L112-L115

          {
              _currentSetting=&_settings[spi_num-1];// SPI channels are called 1 2 and 3 but the array is zero indexed

The STM32Duino core fits the code you have shown with the 4 pins in the consturctor.

          SPIClass::SPIClass(uint32_t mosi, uint32_t miso, uint32_t sclk, uint32_t ssel)
          {
            _spi.pin_miso = digitalPinToPinName(miso);
            _spi.pin_mosi = digitalPinToPinName(mosi);
            _spi.pin_sclk = digitalPinToPinName(sclk);

          /**
            * @brief  Initialize the SPI instance.
            */

So it’s very clear that your sketch was written against STM32Duino/STM32 core and not maple, so using board = bluepill_f103c8 is correct for that. Now to the question

The STM32Duino doesn’t activate the USB CDC interface by default. See Difficulty with getting USB serial [USB CDC] working - #6 by maxgerhardt for the needed flags.

I don’t however know if it’s possible to have the USB DFU bootloader from the Maple core AND the USB CDC from the STM32Duino core running… You might still try to pre-flash the Maple bootlader, add upload_protocol = dfu to the platformio.ini and then upload a STM32Duino firmware.

creatron · March 9, 2020, 7:14am

Thanks a lot, I used the reference to the CDC and it is now working. It is appreciated.

creatron · April 3, 2020, 6:53pm

Thanks it works now…
