Comm2 Comm3 Comm4 SPI I2C PWM

Handles methods for serial communication on Comm2 Handles methods for serial communication on Comm3 Handles methods for serial communication on Comm4 Provides methods for communication over the SPI Busline Provides methods for communication over the I2C Busline Provides access to methods for pulse-width-modulation commands

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.

COMM2/ Comm3/ Comm4 Handles advance options and methods for serial communication
