Re: [PATCH 4/4] STM32F4 GPIO: Add GPIO implementation for STM32F4

Hello, Have you tried a tiny bit to optimize this code because at a quick glance, it sounds like for critical routines, you choose some slow and complicated ways to do simple things, see a few some example below: +static uint16_t GPIO_PIN_x[] = { +GPIO_PIN_0, +GPIO_PIN_1, +
