Emulating UART Part 2: Sending Data
With the timer and GPIO successfully configured, we will now shift our focus to actively transmitting data. By leveraging the TIM3 interrupt, the microcontroller…
Emulating UART Part 1: Introduction and environment Setup
In this new series guide, we shall emulate the UART hardware using a clever combination of timers and DMA to achieve effortless, CPU-independent serial…
