The Stm32f103 Arm Microcontroller And Embedded Systems Work Jun 2026
: Detailed examples for timers, serial communication, ADC, SPI, I2C, PWM, and interfacing with devices like keypads, LCDs, motors, and sensors.

For the next hour, they dove deep. They watched the ARM core fetch the reset vector from 0x08000004 , set the main stack pointer, jump to SystemInit , then to __main . They stepped through the RCC—enabling the USART clock, the GPIO clock. They configured the baud rate register: USART_BRR = 0x1D4C for 115200 at 8 MHz. They watched the transmit data register— USART_DR —fill, then empty as the shift clock pushed bits out onto the TX pin. : Detailed examples for timers, serial communication, ADC,
