LED2 (Blue) Doesnt Work

pb33 · ‎2025-06-13

Hello,

I am using the H753zi board and cannot figure out why my blue led won't turn on. The green and red do work. Any ideas would be greatly appreciated.

Okay so I got them all to turn on. Instead of BSP, I used HAL, for example:

HAL_GPIO_TogglePin(LED1_GPIO_PORT, LED1_PIN); // Green LED

Ok, but which GPIO Bank(s) and Pin(s) ??

Please show whole working code so we might learn what was happening.

@pb33 and you still haven't confirmed what board you actually have.

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
