Max1270 adc

GJ

Has anyone used the MAX 8 channel 12bit ADC with the Javelin and if so, would you be willing to post your code?

In one of the posts there is talk about a Nuts & Volts magazine that
explains javelin code regarding the max1270.

and get the docs and example code (also for javelin) for the StampPLC board.
This board utilizes a MAX1270.
The javelin example code has a read routine and conversion routines.

the code for the Javelin StampPLC board was very useful, thanks for the suggestion.

There appears to be an error in the PLC code for the javelin as it relates to selecting the ADC range. There is a set of variables for identifing the ADC mode. In the original code, the ADC_UP10 and ADC_BP10 are reversed. They should read as follows


static final int ADC_UP5 = 0; // unipolar, 0-5 volts
static final int ADC_BP5 = 1; // bipolar, +/- 5 volts
static final int ADC_UP10 = 2; // unipolar, 0-10 volts
static final int ADC_BP10 = 3; // bipolar, +/- 10 volts
static final int ADC_420 = 4;
