Remember: In embedded systems, there is no magic—only registers, clocks, and well-written drivers. : jxmcu driver work, embedded MCU development, GPIO driver, interrupt driver, UART driver, register manipulation, ARM Cortex-M, STM32 clone, low-level firmware. jxmcu driver work
For I2C and SPI, driver work becomes more complex, requiring state machines for master/slave modes, clock generation, and error handling (NAK, arbitration loss). Even experienced engineers face hurdles. Here are frequent issues and their solutions: void EXTI0_IRQHandler(void) if (EXTI->
