Hi Rob, Sorry, that doesn't make any sense to me, I must be missing something...
With my last version of adc_channels.jal, channels up to 29 is handled. So adc_read(31) doesn't match any case, how could this work ? (the fact my ADC libs were highly resilient was a joke :)) Anyway I'll update with channels up to 31 (one could say I should check this dynamically within template processing...)
