OPAMP example? #23

Closed metanav closed 1 year ago

metanav commented 1 year ago

How can we configure and use the OPAMP? I could not find any code related to the OPAMP peripheral in the core. Only there are a few defines in the variants directory.

This Arduino core was compiled without the "OPAMP" component of the underlying Renesas FSP framework. However, you

  1. Can still add those missing files (https://github.com/renesas/fsp/tree/v4.0.0)
  2. Use direct writes to the OPAMP peripheral registers

I just copied the missing files next to the sketch and created a working OPAMP example for the Uno R4 WiFi, whose OPAMP pins are exposed on the analog pins A1 (Plus), A2 (Minus) and A3 (Output). I successfully tested a simple voltage follower example.

Dear Alexander Entinger et al,

I am a software development professional with 41 calendar-years of experience, hereof somem 15 years in embedded and microprocessors, ranging since the Z80, and up till todays date.

I am CTO in SkyFi Energy Aps of Denmark and CEO of Rational Intuitive Ltd. of Kenya. My question is:

I am heading a team of quite young developers with maybe 2 to 5 years of experience, mainly on the Web/Fullstack side of it.

We have decided on developing a product which will be using the Arduino UNO R4, due to its versatility, Bluetooth, WiFi, CAN-bus, RTC etc., and I would therefore like to understand how I can contribute from time to time on the development of the software residing on GitHub.

Sincerely Yours, David Svarrer
