UART Serial communication on the BCore is available through the use of UART. The BCore board has 4 UARTs supported by the BCoreOS under the name of Comm1/2/3/4. Comm2/3/4 supports advance UART options Full duplex, 8 or 9bit transmission Addressing Mode No parity One Stop Bit Baud Rate: Varying Standard Baud Rates 4 word deep FIFO Data Receive Buffer
Comm2 Located at JST5. *Note: COMM2 pins are shared with SPI pins. Please note that only COMM2 or SPI may be used at any one time.
Comm3 Pin Location: TX: JP1 ; RX: JST5. *Note: COMM3 Pins are shared with SPI and LED1. Only COMM3 or SPI pins may be used at any one time.
Comm4 Located at PORT5, pins 47 & 48. *Note: COMM4 Pins are shared with the OLED Data Bus Line.
