#Spi programmer on arduino mega2560 software
Now, there are three aspects of this project - hardware, firmware, and software and here the details for each. Here are a few links, more links on OpenTx homepage: hex for MEGA2560Īlright, since I already have relevant information in this post, I'm going to use it as the build guide.įirst of all I'm just borrowing information from others, especially the OpenTx guys. Update: May 19, 2015: Added a mini build guide to post #12 along with pre-compiled. * 6 Menu navigation keys - Menu/Exit/Left/Righ/Up/Down * Upto 2 Rotary encoders (1 can be used for menu navigation) * DR switches for THR/RUD/ELE/AIL channels * 3 Pots (All three can be converted to 3 position switches) Ideas/suggestions/questions are welcome too!īTW just in case, here are some of the features of MEGA2560 DIY Radio: Meanwhile, it'd be interesting to see if anyone has done work in this area. I will post the pics and other information as I make progress and once I have the radio working, I intend to post a "build guide" to help ease the build for others. So I thought of starting this thread to record my experience, in case someone else wants to do this too. When I started out, I was surprised by lack of building information online. Then the plan is to try and fit the Arduino, LCD, and rest of the electronics in the T6 box. I just need a LCD display and additional switches/Pot. So I already have the Tx box with most of the controls required for radio already in place. I could not find a replacement main board either and had to buy a 9XR. The T6 is useless for me because I blew up the main board in the process of trying to use a 3S LiPo. So my idea is to sacrifice the FS T6 radio I have lying around. The radio supports PPM/DSM protocols and appropriate add-on RF module can be used for RF link. Arduino MEGA2560 board is then flashed with OpenTx and hooked up to the controls to complete the radio. DIY radio involves fitting the gimbals, switches, pots etc in a home made box.
#Spi programmer on arduino mega2560 upgrade
Since it was first time ever I was trying to upgrade to OpenTx, I had to walk through a whole bunch of information and in that process I came across the DIY radio version of OpenTx with Arduino MEGA2560 board and that's the project I'm working on these days.

So, I switched to OpenTx just to get 30 models and I'm amazed by the capabilities of the firmware and the companion SW. Actually, I was quite happy with the stock 9XR except I was running out of 16 model slots.

So, I recently upgraded my 9XR to OpenTx.
