I had a need to program SPI eeproms so looked around and found this for Arduino and off-course
it requires a 3.3V Arudino, I only had the Blue pill clone so I adapted the code and modified it
slightly to work with the pill attached is the connection schematics and code.
You will need to program the Pill with a bootloader for it to work as Arduino board.
Also add a clip into the mix and create an ICSP.
You can use a serial console directly on the pill or the python script on the original repo
tested on Windows and Linux.

| Chip pin | Blue pill pin |
| 1 /SS | PA4 |
| 2 MISO | PA6 |
| 3 /WP | +3.3V |
| 4 GND | GND |
| 5 MOSI | PA7 |
| 6 SCK | PA5 |
| 7 /HOLD | +3.3V |
| 8 VDD | +3.3V |
