unsigned int anaInDriver(unsigned int cmd,
Reads the voltage of an analog input channel by serial-clocking an 8-bit command to the ADS7870
device by its Direct Mode method. The conversion begins as soon as the last data bit is transferred.
An exception error will occur if Direct Mode bit D7 is not set.
cmd contains a gain code and a channel code as follows.
Use the following calculation and the tables below to determine cmd:
len, the output bit length, is always 12 bits.
unsigned int len);
D7—1; D6–D4—Gain Code; D3–D0—Channel Code
cmd = 0x80 | (gain_code*16) + channel_code
