hardware hack OPI Zero Plus H5 and GPIO library

[JRD McLAREN]

Hello everybody.

 

I'm little bit confused with this think.

Which libraries are good (best) for H5 OPiZeroPlus board .?

 - WiringPI

 - ArmbianIO

 - GPIOzero

 

or ..??

 

I have small script for timer switch, but it is not stably as well as I can.

Button press is not accurate. (some pull-up/down are missing probably)

 

Thanks for answer or suggestion.

 

(PS: I'm not a programmer guru)

Hi Jrd,

 

I also just started programming the OPi Zero Plus and I am using ArmbianIO as I understood the other two are for the Raspberry or don't support the H5. The problem that you describe could be contact bounce maybe? I didn't get to test the buttons in my project yet.

Hello,

Contact bounce is not problem. I have 1nF Cap on it ...

Without cap is button like this unusable.

Within armbian you find following User-Supported options:

ArmbianIO (sysFS) or
userspaceIO (libgpiod),
pyGPIO accesses 'pins' directly through /dev/mem

 ArmbianIO API

 User Space IO is Python 3 and Java 8 bindings for user space GPIO, SPI, I2C, PWM and Serial interfaces
