int anaInDriver(unsigned char cmd, char len);
Reads the voltage of an analog input channel by serially clocking out an 8-bit command to the A/D con-
verter. The driver has been designed for the Texas Instruments TLC2543 A/D converter used on the
BL2100 and the BL2120.
cmd is formatted as follows.
TLC2543 commands
len is the output data length:
A value corresponding to the voltage on the A/D converter input channel, which will be:
