Android - Raspberry Pi B Rev 2: Only virtual pins available

I followed your tutorial for the Raspberry. Starting Blynk in Raspbian seems to work and it is discovered in the Android app. If I want to select pins for a widget (e.g. ZeRGBa), however, only the virtual pins 0-64 and the digital pin “gp18” are available. I want to use pins 22-24 though. Am I doing something wrong or is this a bug?

I don’t think it’s a bug

I think you can’t use digital pins because they are only able to send 1 or 0 signal . It means you would only be able to have “simple” rgb colors ! Full blue, reg, green or mixed (total 7 colors) . So that’s why you can’t use them! I think the idea of this widget is to send the values through virtual pins to be processed by your code

I could be wrong but that’s my point of view .

Any solution please paste here

Thanks, you are right about the limitation of the app/Blynk. Only 0/1 buttons work with the digital pins, there I can see all of them.

I kind of understand your explanation. Of course I can assign values 0-255 to the GPIOs (hardware) using e.g. pigpio and I expected this functionality to be implemented in the ZeRGBa widget. But apparently that’s not the idea of Blynk so I’ll have to look into programming the virtual pins.

This is considered to be a correct behaviour. It’s the limitation of hardware platform.
