0xA9 – A/D Conversion

Parameters:

Returns:

Function:

Example:

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, 0xA9 – Selects analog channel 2 (AN2), performs the A/D

conversion, and returns 2 bytes of data.

0xAA – EEPROM Read

Parameters:

Returns:

Function:

Example:

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.

0xAB – EEPROM Write

Parameters:

Returns:

Function:

Example:

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.
