Signal to H-Bridge used to control IR Source On/OFF {1/0} Connects to T1IN of MAX232 device. Provides RS232 data output for system. SPI Serial Data Output pin that connects to the Microchip MCP4822 DAC device SPI Clock Output to Microchip MCP4822 SPI DAC device
SPI-DAC A Microchip MCP4822, Digital to Similarity Converter with SPI port and interior action connects the dsPIC30F soul to the buffer amplifiers. This emblem takes a 12 bit bid over the SPI attach. The SPI is falsehood for a 16 bit express transfer using a 7.3728MHz clock.
The round 12 bits of the language are aggregation and the bunk nibble are test bits. One of these essay bits is victimized to select one of the two DAC circuits in the pattern. DAC turnout A (pin 8 ) controls the grade of the IR Led piece DAC product B controls (pin 6), the RED emitter.
