【应用笔记】STM8A UART的模拟器 AN2800 Application note STM8A UART emulator Introduction This application note describes a technique to emulate the universal asynchronous receiver transmitter (UART) hardware peripheral, through the microcontroller medium end timer (TIMER3), without the use of additional hardware. TIMER3 was chosen for this purpose because its capture and compare features can be easily used to receive and transmit data in a non return to zero (NRZ) serial format. This timer also provides a necessary time reference to establ……
