The modules TEI0015 and TEI0016 implements a handler for executing commands. The serial interface speed
must be set to 115200 bits, commands consists of a single character in UTF-8 encoding.
Each command must be transmitted individually.
These commands apply since module revision 03.
"1" Sets the pre-amplification of the ADC's input to 1. Firmware dependend
"2" Sets the pre-amplification of the ADC's input to 2. Firmware dependend
"4" Sets the pre-amplification of the ADC's input to 4. Firmware dependend
"8" Sets the pre-amplification of the ADC's input to 8. Firmware dependend
"r" The ADC measure once and transmits this value
"t" The ADC measures 1 mega samples and saves the values into its SD-RAM
"." A single value of stored ADC measurment is transmitted
"+" 128 values of stored ADC measurements are transmitted
"*" 16 kbit values of stored ADC measurements are transmitted
"x" Instead of ADC values the value "12345" is stored 1M times in RAM, values are transmitted via ".", "+" and "*"
"y" Instead of ADC value, hexadecimal values, in ascending order, are generated and stored into the SD-RAM,
the values are transmitted in via "." , "+" and "*"
"z" The value "12345" is generated and direct transmitted 256 times
"?" The module returns its ID:
TEI0015 with ADC AD4003 / 2 MSps returns "1"
TEI0016 with ADC ADAQ7988 / 0.5 MSps returns "2"
TEI0016 with ADC ADAQ7980 / 1 MSps returns "3"
