# STM32 Bluepill Quickstart
|
|
|
|
## Temporary files
|
|
Create files and directories within the project temp directory e.g.: `~/.gemini/tmp/d9929d1c794fb414052498bc12a08fef640ff8b7c30d9190d0699962781facbf`
|
|
|
|
## Compilation
|
|
|
|
To compile the sketch, run the following command from the project root:
|
|
|
|
```bash
|
|
arduino-cli compile --fqbn STMicroelectronics:stm32:GenF1:pnum=BLUEPILL_F103CB,upload_method=OpenOCDDapLink --build-path /tmp/$(basename $(pwd)) .
|
|
```
|
|
|
|
## Flashing
|
|
|
|
To flash the sketch use `openocd` to flash the sketch.
|
|
|
|
```bash
|
|
openocd -d2 -f interface/cmsis-dap.cfg -f target/stm32f1x.cfg -c "program {/tmp/$(basename $(pwd))/$(basename $(pwd)).ino.elf} verify reset exit"
|
|
```
|
|
|
|
## Viewing Logs
|
|
|
|
The best way for me to read the logs is to capture the output from the serial port to a file, and then read that file.
|
|
|
|
1. First, I'd configure the serial port settings without starting an interactive session using `stty`.
|
|
2. Then, I'd use a command like `head` to read a specific number of lines from the serial port and save them to a temporary file. This command will exit automatically after reading the lines.
|
|
3. Finally, I would use `read_file` to read the contents of that temporary file.
