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.
We described simple method, how to drive modellers servo. Today, we are going to try to drive this servo from potentiometer connected to TR module ADC. It is reaction to forum thread where is discussion about airplane model control possibility. Continue reading
Today, I focussed on another example from IQRF Startup package – Servo control. You will find this example inside Advanced examples of Startup package. You can use this user code together with ADC example described earlier and make automatic wireless control device.
