One year ago, I published two posts about PWM module driven by IQRF . But there is also another way, how to generate PWM signal from IQRF TR module only. Just simple use PIC peripherals. This post is based on one of Advanced examples, which is part of IQRF Startup Package.
I like TR-52D modules, but I was disappointed of their DAC capabilities inherited from used MCU. Fortunately we have several ways, how to fix this issue. One of them is AS1500 digital potentiometer usage. It is very simple (from programming view) device and not so expensive. Following example is only draft. For fully functional circuit, some additional hardware is required.
This is simple illustration how to build easy PWM LED control with IQRF TR module and a few other components. Continue reading
