I'm glad someone took interest in my project. Unfortunately, I stopped development at some point, but want to continue it in the near future.
I used BlackPill board (F1), so I'm not sure if everything will work correctly on bluepill, but since they use the same MCU, there's a high chance it will.
To upload the code, I used PlatformIO IDE and ST-Link programmer.
If you manage to successfully flash the bluepill board, and it registers as a MIDI device, I can provide the schematics and help you modify the code for your needs.

Thank you for reply, can you tell me which part need to modify for my buttons request ( 16 buttons ) also i need schematic for testing thank you!
Here's a schematic you can try
For code editing, you should look at the main.c
file. In particular, the gpio_setup()
and sys_tick_handler()
functions, and these lines:
static bool key_states[8];
static uint8_t key_number[8] = { 44, 45, 46, 47, 48, 49, 50, 51 };
static uint16_t key_gpio[8]
= { GPIO0, GPIO1, GPIO2, GPIO3, GPIO4, GPIO5, GPIO6, GPIO7 };
static uint16_t key_gpios;
The code assumes all buttons are connected to GPIO Port A. If you need to use buttons connected to other GPIO ports or use a scan matrix, you will need to write some more logic in the code which I did not have time to add.
I'll buy blackpill and some potentiomters and diode I really want to move from arduino uno to stm32 for faster midi communication, hope you can help to finish it 😫
What's wrong with bluepill ?
What's wrong with bluepill ?
I create a new project with bluepill and import your code to compile it but when upload hex via stm utility done the usb midi driver show error on board
Can you upload the schematic and how to upload code for stm32f103c8t6 bluepill? I want to make 16 buttons from note 36 to 51 can you give me the code of that?
