Re: boards and kits and stuff
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

Re: boards and kits and stuff
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

Re: boards and kits and stuff
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.

Re: boards and kits and stuff
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

Re: boards and kits and stuff
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

Re: boards and kits and stuff
*** 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

Re: boards and kits and stuff
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
By Terrance Robertson, KN6ZDE · #33132 ·
Re: boards and kits and stuff
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,

Re: boards and kits and stuff
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

Re: boards and kits and stuff
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.
