Having upgraded my 7E to 6 switches, the next thing I worked on was to add 2 potentiometers to it. These will show up as AUX4 and AUX5 inside the DeviationTX firmware. It’s a slightly trickier process than the switch upgrade, as there are no convenient pins on the main board to use. As such, it requires soldering directly to the pins on the processor. This however, like the processor upgrade, can be done safely if you take the necessary…
[UPDATE: 17th May 2016] While the method below can still be used to build from source, PhracturedBlue has release a Docker container that contains the build environment with a GUI to ease the process. Find the wiki documentation about it here. Alternatively, if you do not want to build from source yourself, compiled versions can be found on the Test Builds page on deviationtx.com. Let’s walk through the process of building DeviationTX from source. You’ll need to do this if you…
We’ve now got a nice new processor installed in our 7e and we need to flash a boot loader onto it. The bootloader we need is the 256K variant that PhracturedBlue has so nicely modified for us. It is based on the original stock Walkera bootloader, but allows for files larger than 128K to be uploaded. You can find it from the links that I put in the “DeviationTX: Build environment and tools” post. I’ll assume that you’ve also already acquired and…
This is a short post of the build environment and tools that I have been using to experiment with and hack the Devo7e. With these tools, we can recover from permanently bricking the transmitter (most of the time). A quick list to make everything easy to find: Walkera Dfuse Upgrade Tool (Linked on deviationtx.com) Deviation Uploader (Download from deviationtx.com) Docker (docker.com) MWM’s Deviation Docker image (Link to forum post) PhracturedBlue’s Docker build environment container (Link to wiki) PhracturedBlue’s Devo7e bootloaders (Stock 128K and Upgraded…
I took the plunge and decided to upgrade the processor in my Devo7e transmitter to a STM32F103RET6. This upgrade is not yet officially supported by the DeviationTX team yet, but I figured it was doable as the upgrade doesn’t really affect the code much and I’m fairly comfortable with compiling from source code. In this post, we’ll look at the hardware end of the upgrade. Desoldering and resoldering a SMD processor isn’t really that hard and the potential for damaging your…
