    Analog shield dimensions?

    Hi @jpeyron For the pdf you posted, it is missing the x-dimension for the 2x4 and 2x5 on the left. Do you know what that is? Cheers, William
  2. Thanks JColvin, I figured it was something like that. Many thanks. Cheers, William
  3. Hi, When I configure certain digital pins to be inputs, I can not longer update the DACs. Rather strangely, I can configure pin 8, 9, 10, and 12 as inputs without problem, but setting pins 11 and 13 to be inputs stops communication with the DACS. There is no issue if they are configured as outputs. For example, the following works as expected with DAC1 ramping #include <analogShield.h> //Include to use analog shield. #include <SPI.h> //required for ChipKIT but does not affect Arduino void setup() { pinMode(12, INPUT); } unsigned int ramp = 2000; void loop() { // put your main code here, to run repeatedly: analog.write(1, ramp); ramp++; } If pinMode(12, INPUT) is changed to either pinMode(11, INPUT) or pinMode(13, INPUT), DAC1 does not ramp. The same behaviour is seen on all DACS. Any ideas why? Thanks in advance. I am using this library: https://github.com/wespo/analogShield
