Button Board vs. Touch Board Questions

Hello there! I hope to find a solution/inspiration here in the forum. I use various Arylic boards (here the Amp 2 v3, FW: 4.6.337862.29 . After I was finally able to build a button board myself without the error on the circuit diagram and it works reliably, I am looking for a touch solution as shown in the picture "I find it better to do tasks on the device than always having to use the remote control or the smartphone. Unfortunately I can’t find a name for the IC in this example. However, the …

Problem with ADC-KEY Board (with Mini V)

I am using a ADC-KEY Board with a MiniV3. The white LED for WiFi on the ADC-KEY Board is on. When I press one of the buttons, nothing happens. An IR receiver conntected to the ADC-KEY Board does also not work (IR receiver of the Mini V itself works). Any help appreciated. Lora [arylic]

SOLVED: Issues with ADC Button Resistor Values

Hey All. I am getting inconsistent results when attempting to setup the ADC buttons based on the specs: [Screenshot 2021-06-08 184327] This applies in my case to the 2.1 amp. The only functions I have managed to successfully implement are: On/Off (not documented. discovered by accident) Mode Play/Payse Next But even these are not perfect. Based on 3.3v supply, I have calculated the following voltages based on the resistor value specified. Note that - applying 0V to ADC seems to switch the…

please ignore the internal 10k resistor, then the preset buttons will also be correct…good luck joerg
