Raspberry pi works great for SDR's, C and or C++ is standard (linux). I even port a lot of Arduino libraries to the pi for managing I2C chips. But if you want to debug Arduido (or raspberry pi for

I would suggest that if you want to try using a different processor, just make a new main board and keep the other V12 boards.? The MPU used on the Teensy is either a BGA or a very dense QFTP, not

Yeah, I mainly used the discovery board as a test bed for the dual-core processor.? I thought it would make my testing easier given that it came with a display.? That's when I learned how much we've

“Perhaps he can jump in and talk about debugging and library support.” Yeah… I’d love to hear what he as to say about that too. He sure got the sBITx working in a hurry after the uBITx… Dr.

The call sign/grid square info could be moved to the SD card and not be part of the raw code. All you would need is a text file with that info on the SD card and then add a trivial amount of code to

If I were going to start over, I might consider the Raspberry Pi. It has the memory resources and clock speed to pull it off and a 10" 1024x600 display is less than $50, so overall it costs less than

*** Amen! The raspberry pi Pico has become my go-to for little projects because it supports SWD ( single wire debug ). Breakpoints. Source level single step. Etc. Shortens development time by an order

I spent about a month working with the STM32H747I-DISCO Discovery board.? It has good debugging capabilities. My goal was to get a mockup of the T41 code running on the dual core processor, with DSP

I agree. The T41 development time would have been years less if there was a decent debugger. I can't believe that the Arduino people don't have the talent to incorporate a debugger in the IDE. Jack,

My experience with the display is different (better) because I made changes to the design while still using the same display driver IC. The display problems I was referring to are V12 only.? Basic

It’s a pretty solid machine but that is without plugging it in yet… so don’t know exactly what will happen long term. I did get the circuit board making kit and the example is a LED board with

Got the laser attachment and the rotating 4th axis as well… Uses G-code so compatible with a lot of systems and sortwares. Works with aluminum, wood, plastic, glass, etc. Can’t wait to try it! Dr.

Sounds like you got a good machine.? I'm guessing your experience will go better than mine.? I tried this with a budget CNC a year ago.? After a bit of a learning curve and some small successes, I

Looking back at my notes, I see I misspoke: With a long display cable, the v12 code hangs while trying to start the RA8875 object in the setup routine.

I've tested this.? The T41 doesn't get to the setup routine when a long display cable is used.? It gets stuck trying to create the RA8875 object.
