Updated. Please, look here viewtopic.php?f=3427&t=25646&start=10. I got 2xACS712 for tests.

Sorry for the waiting. Finally I have a time for ADC. So, yes, there is a very strange behavior when I try to use multiple channels. I have to go deeper to hardware to say what is wrong. I confirm the behavior of ADC that Peter and knst08 has reported previously. I'll try to find the reason and fix ...

Please have a look to different settings I listed in viewtopic.php?f=3427&t=25646. Try to apply this and check the behavior. Looks like it's a internal behavior of ADC. I'll try to get an ACS712 for tests.

Post your sketch here, or you can send me it by means of PM. Don't worry, we will help you.

Hi, you can't see the output of the Serial in setup() because it's a native USB port and it goes to reboot with the Z-Uno, but Serial0/Serial1 + UART2USB have to work properly for debug. It's more comfortable way to use UART0 for debug purposes. Use external software to look for the output of Serial...

The workaround is to initialize it after the first loop(in the second loop). For example try this: byte loop_cnt = 0; void loop() { if(loop_cnt < 2) { if(loop_cnt == 1) { // ... pinMode(5, INPUT_PULLUP); // ... } loop_cnt++; } }

This have to work in the sketch file:

Hi, Yes, now it works only for globals. It's not a good idea to place this on the stack. Parameters use dword type, so it's 4 bytes of stack for one parameter. We try to make it clear for the next release. zunoSaveCFGParam() have to work. The main limitation that you can't do a filtering of values b...

Don't do them private! When you add them to class you increase the parameter list. They have to work fine with multiple displays too, because the parameters will be buffered anyway. Please, modify the code carefully. The right way is to add additional global variable for current backlight, or add th...

It sounds great. I don't have a time to check your example on the hardware myself, but I have a little time to refresh some info from datasheet and look into code. So, there are some new data: 1. ADC0(VRef+) & ADC1(VRef-) can be used as voltage references. May be it's a side affect of this. Code...
