Arduino for STM32

The boards have the stm32duino booloader installed.

When I connect it to the usb to update the firmware via cube programmer, the USB does not recognize it and via UART, it gives this error:

Error connecting devide KO .... blah blah

Do you know if it´s possible to use the cube programmer with the ...

Can you upload via USB with the STM32CubeProgrammer or it works only for the 4 pins port?

Im trying to use dfu-utils but it is command console driven only, isnt?

Fantastic. I will check. Many thanks! =D

Great, I´ll look into monitors. Thank you so much, Steve =D

But this would force users to compile sketches, something that mostly arent capable of.

Is there any way of sending them just the .bin file to directly upload via USB?


I guess worst case scenario I can say them to get 2usd stlinks and upload from there, but having the usb and the bootloader ...

I would like to develop a command console similar to the one in the arduino IDE, where you can read serial data and also send commands to the bluepill via USB serial

I know some java, so I could program it there. Im just wondering if something similar does exists that I can build on it so I dont ...

Im producing some updates to bluepills. In arduino I tell users to use XLOADER to upload the hex files.

What would be the equivalent in the blue pill so users can update via USB?

(Their bluepills have the stm32bootloader installed)

This post has an exemple on how to use SPI2 with Roger's core:
https://github.com/rogerclarkmelbourne/Arduino_STM32/pull/536



void setup() {
// Source: https://community.platformio.org/t/pio-arduino-stm32f103cbt6-remap/6786/5
afio_cfg_debug_ports(AFIO_DEBUG_SW_ONLY); // PB3 free

Roger Clark, the creator of the libary said to do:

SPI.setMOSI(PB15);
SPI.setMISO(PB14);
SPI.setSCLK(PB13);
SPI.begin();

Or:

SPIClass SPI_2(PB15,PB14,PB13);
SPI_2.begin();


This is related to Official STM32 Core.

I totally ...

a few words about platformio
depends on which board you selected, your platformio project can use roger's (maple target) or official (stm32 target) core and those cores are not compatible in case of SPI


Thank you so much for the info. What are the differences between Roger´s and Official ones ...
