Hello Casperites, I read with interest Hong Chen's memo on the external adjustment of the iADC board at:
https://casper.berkeley.edu/wiki/External_Adjustment_for_the_Atmel_iADC I am most interested in the ability to control, calibrate and compensate the ADC board with controlling the iadc_controller device file. Is there documentation in the following aspects of the CASPER ecosystem, specifically for ADC boards. I would appreciate pointers on finding either code segments or real documentation on these: * Aspects of the iADC board registers. How to activate these registers? You seem to be reading 128 bytes each time you read from the file system handle 'iadc_controller'. Where are the docs for these? * Are there equivalent instructions for other ADC boards like KatADC? * How exactly do devices like iadc_controller get created? Pointers to where in the source code to look at would be great! * I would appreciate general pointers as to where the file system handles for things seen in listdev() are created? For eg. sys_clkcounter, etc.? Thanks in anticipation for your help!
