This is for those who are looking for embedded basics and microcontroller basics. Please be sure to answer the question. I can set up my UART to transmit on a CC2650/using TIRTOS, but I want to set it up to trigger an interrupt and read whenever a new message comes in on the RX line. That said, I'm running into an issue that I could solve if I had direct register access, but I cannot solve using my knowledge of a Linux serial port. Introduction To UART Universal Asynchronous Receiver/Transmitter or UART for short represents the hardware circuitry (module) being used for the serial communication. Tutorial : Embedded programming basics in C – bitwise operations form the basis of embedded programming. 6kbps to 1Mbps in UART-to-UART, UART-to-I²C, and I²C-to-I²C mode Is it possible to use integrated UART interface instead of I2C? How to remap pins to UART interfaces?. List of Interview Questions on Embedded Processor, more specific to microcontroller and assembler. Protocol is binary, baud rate is changed during init (9600 startup, 115200 normally), no flow control pins available (only tx/rx/ground). A UART's FIFO buffer is designed to improve. Learn to mix c and assembly programs together and call assembly functions in c program. mbedded c aka embedded c post on What is UART (Universal Asynchronous Receiver/Transmitter) which is one of the embedded interview questions. 2) Audio / Video projects.
