Example:
V1.1
Analog Port Number – Selects the analog port for the A/D conversion.
2 Bytes: The 10-bit voltage data; LSB first.
This function will set the channel for the A/D conversion, pause 10uS, perform
the A/D conversion, and then return 2 bytes to the host (LSB first). Command
0xA8 must have been previously called to configure the desired analog channel
as an A/D input.
0x2, 0xA9, 0x2, 0xA8 – Selects analog channel 2 (AN2), performs the A/D
conversion, and returns 2 bytes of data.
Address – Selects the zero-based address of the location in the 16F877A’s
internal EEPROM for reading.
1 Byte: The byte of data read from the EEPROM.
This function will read the selected location in the 16F877A’s internal EEPROM.
0x2, 0xAA, 0x2, 0xAA – Reads EEPROM Address 2, and returns a single byte of
data.
Address – Selects the zero-based address of the location in the 16F877A’s
internal EEPROM for writing.
Data – Data to be written to the EEPROM.
Undefined.
This function will write the selected location in the 16F877A’s internal EEPROM.
0x3, 0xAA, 0x2, 0xFE, 0x55 – Writes a value of 0xFE to EEPROM Address 2.
