Re: Encoder board differences
¿ªÔÆÌåÓýYes.? You simply daisy-chain another set of front panel boards on the cable from the MAIN board.? The additional front panel board sets must have a unique address (different from the one you currently have installed). ? I have two additional FP electronic boards attached (I did not populate the button parts¡ just the encoder parts) so have 4 additional dual encoders connected.? It could be a mix of up to 8 single encoders, but I wanted to prove that I could use the dual encoders for things that are stored by button access are normally on an encoder in other radios (like RF gain or power, filter width, etc.). ? ?

Re: Initial Test of Main V12.6 board
¿ªÔÆÌåÓýOk one more test you can run¡ The AUDIO HAT¡ and the RF board uses ¡°WIRE¡± (not ¡°WIRE1¡± or ¡°WIRE2¡±)¡ so you could build the control portion of the RF board and try that to make sure that ¡°WIRE¡± is working correctly.? I guess you could also connect to the ¡°RF CONTROL¡± connector on the MAIN board to a bread-boarded MCP27018 with address 0x27 (which is ¡°111¡± for A0, A1, A2) to see if it returns the part imitating the RF board.??

Re: Initial Test of Main V12.6 board
Thanks Jack and Bill,
Yesterday, I successfully ran the ASCII code.
Today, I built the Front Panel board and connected it. Success on Wire1. I2C device found at address 0x20: Front panel MCP23017 for switches 1-16 !So, it's between the Audio Adapter and the Teensy Audio Hat. I have ordered some Stacking Header strips with enough pins that I don't need to Dremel two 12 pins to make them fit. That is my only guess, that the two sets didn't line up perfect and maybe one was pushing on the connection one way and the other the opposite way. Until they arrive, I will look into the PRCJ docs on breadboarding the Teensy with the Audio Hat to see if something turns up.
Am I the only one that this happened to, not only that but two board sets in a row.

Re: Encoder board differences
¿ªÔÆÌåÓýBy the way¡ most people don¡¯t know this¡ but if you want more controls¡ switches and encoders on your radio to work with and program into software, you can add up to 4 front panel boards with 4 more encoders and 18 buttons (or if you don¡¯t populate the button decoder, up to 24 more encoders¡ or if you just want a lot more buttons¡ up to 108 more buttons¡ or some combination of this).?

Re: Initial Test of Main V12.6 board
John: I would simply plug in the USB connector on the new Teensy, before you even solder pins on it, and run the ASCII Table example program. I use this program (Example-->Communications-->ASCIITable) because it also writes to the Serial object as part of its execution. If that's okay, at least you know you have a working Teensy and IDE. I would then hook up the Main board and the display and see if that works. If not, you should still be able to run the "Gauges" program that's in the RA8875 library (no hat necessary). If that fails, then something is wrong with the display or the Main board. Also, these simple tests don't use the front panel at all, so you don't have to contend with those, either. Jack, W8TEE

Re: Initial Test of Main V12.6 board
Still no I2C device found :(
I ohmed out all the connections between the stacked header pins through the Teensy and to the Teensy Audio adapter. I found some intermittent connection issues, which I think is due to the Tayda A-4662 male pin set for the Audio Hat. I noticed that Tayda sent me a substitute part, and I noticed that the pins were not as long a normal pins. So, I started over with a new Teensy 4.1, offset Audio adapter board and Teensy Audio board and longer header pins. I took lots of time to ensure that all solder joints were good and then used an ohm meter to check each pin from the stacked header pins to the Audio board. All were good. I programmed the board with just the Teensy, adapter, and Audio board. Arudino IDE notice a? new board and port and did some automatic updates.?
The is started reporting no I2C device found. I'm not sure where to go from here...2 strikes. I am using Arduino IDE version 2.3.6 Maybe I am missing a library?? ?
