Hoping for guidance on custom split QMK using Blackpill (lemmy.world)

Hi all,

I'm hoping for some troubleshooting tips. I have a self-build split keyboard using Blackpills.

If I flash either side with 'SPLIT_KEYBOARD = no' in my rules.mk, then both sides work fine (but both working as the left side). If however I set 'SPLIT_KEYBOARD = yes', then both sides stop working.

It's driving me insane!

These are the relevant details of rules.mk:

MCU = STM32F401
BOOTLOADER = stm32-dfu
SPLIT_KEYBOARD = yes
SERIAL_DRIVER = usart

And config.h:

#pragma once
#define HAL_USE_SERIAL TRUE
#define SOFT_SERIAL_PIN A12
#define MASTER_LEFT
#define MATRIX_ROWS 6
#define MATRIX_COLS 6
#define SERIAL_USART_DRIVER SD1
#define SERIAL_USART_TX_PAL_MODE 7

And halconf.h:

#pragma once
#define SERIAL_USB_BUFFERS_SIZE 256
#include_next

And mcuconf.h:

#pragma once
#include_next 
#undef STM32_SERIAL_USE_USART1
#define STM32_SERIAL_USE_USART1 TRUE

Please help! I've been at this for three days.

Ergonomic, split and other weird keyboards

Rules

Keep it ergo

Posts must be of/about keyboards that have a clear delineation between the left and right halves of the keyboard, column stagger, or both. This includes one-handed (one half doesn't exist, what clearer delineation is that!?)

i.e. no regular non-split¹ row-stagger and no non-split¹ ortholinear²

¹ split meaning a separation of the halves, whether fixed in place or entirely separate, both are fine.
² ortholinear meaning keys layed out in a grid
