Description

Experience Level: Intermediate
The project involves the development of a BeagleBone Black(BBB) Expansion Board (Cape) which has 4 analogue inputs, 7 digital inputs, 4 analogue outputs and 7 digital outputs. Analogue In/Out requires to handle 4-20mA, 1-5V DC and HART. Example HART circuitry available. The Cape shall have an associated microcontroller/processor interfacing to the ADC and DAC 4 channel IC, and this microcontroller shall also require to interface via UART to 8 HART modems (one for each ADC / DAC), as well as an additional RS232/RS422/RS485 serial port. Actual HART and serial stacks outwith scope of supply, with the Microcontroller requiring to act as FIFO buffers for these 9 UART. Interface with the BBB from the Microcontroller shall be via I2C, with the Cape microcontroller acting in slave emulation mode.
