In an earlier post, python was used to generate an image from datasets. That method lacked the full features needed to create a final image. This post will introduce Plotly as a preferred method. It offers more options and is targeted for use as a tool for dataset visualization. First we’ll need a dataset that is tangible. In this post the dataset will be generated from a field scan to create an image array. The device used to scan the…
The FlySky TX has some interesting features that allow it to display sensor readings from a RX. Having a ground based data logger made looking into this worthwhile. This post will cover the process used by the FlySky for sensor readings as well as interfacing micro controllers as a sensor source. There is a community of developers that have done a bulk of the work presented here and an effort will be made to give credit to them. The FlySky…
RSSI, which stands for received signal strength indication, was covered in the last post. The topic covered how the Nordic Seminconductor’s nRF240L0 wireless device could be used to measure RSSI values. Those values reveal the reliability of the radio controlled reception and interference that might be present. RSSI telemetry is basically a tool to see invisible radio waves that operate on the same operating frequency as the radio controller (TX) and receiver (RX). FlySky is a manufacturer based out of…
