In a previous post [https://ab1tj.com/experimenting-with-digital-aerochrome/], I was manually combining the RGB channels, with a bunch of experimentation to try to select the right channels, and a decent amount of color correction. I've not been able to maintain a stable shoot order, especially for full color/…
In addition to needing to delete those few lines in pl.dtsi, I needed to alter my kernel command line to enable the uio module in a certain way. My current system-user.dtsi file is: /include/ "system-conf.dtsi" /{ chosen { bootargs = "earlycon console=ttyPS0,115200 clk_ignore_unused…

This is mostly a note for myself, but maybe it will eb useful. I struggled for too long to get the ILA logic analyzer up and running in Vivado for a simple project. It seemed I was missing a lot of knowledge. Here's a step-by-step in getting it…
My latest project involves charging a 12V, 3S LiIon battery over a POE connection, so limited power. I want to charge the battery over a day, at around 5W, then use that power at night for radio stuff. For the POE splitter, I think I want to use 12V output,…
This is a scratch pad for a small 70cm FPV transmitter. DTV is a bust. No one makes a single chip MPEG or NTSC to DVB or ATSC signal chip. Analog is easier, and the chips are kind of available. Modulator: Can use the MC44BS373 or similar (NTSC RF Modulator)…
