Re: [AmateurRadioBuilders] RP Pico 2
You didn't read what I said. Each "page" (your term, not mine) is a segment of the display and only that gets updated. Jack, W8TEE

Re: [AmateurRadioBuilders] RP Pico 2
I think the Teensy could work with only 3 function calls to the Pico (or whatever??) processor for each page: ??? 1. Show -- present the default page being called. Essentially, one page for each new screen. By new, I mean overlays ??????????? on the display surface (e.g., Info Window, waterfall, spectrum, audio plot, S-meter). Some of these are in a tight ??????????? loop controlled by the Teensy (e.g., spectrum). ??? 2. Update -- if new info comes to the Teensy, it can be forwarded to update that page on the screen. ??? 3. Close -- that page is removed from the display, leaving a black background in its place. If written correctly, the second processor could almost be anything that has a decent clock speed and memory. Keep in mind that the display supports the Block Transfer Engine (BTE) that can speed things up on the display updates. Jack, W8TEE

It does do SPI, so it could control our current display - assuming that there's an RA8875 library available. ? The first step would be to isolate all access to the display.? Make sure it's all in one file.? I would use C++ objects to encapsulate it.? Pages and items. A "page" would be an entire display - say the normal radio display.? Or the BIT test display.?

Once something like that was in place, it would be straightforward to substitute "page" calls with calls to a different file that squirted the info out to the Pico. The object of the exercise is to minimize this info.? Only the Pico would know exactly where on the screen something goes, for example. ? So if the Teensy can just say "display the main screen" to the Pico, that's a lot less work for the Teensy.? There's no way around sending the individual readings for the spectrum.? But the Pico would maintain the waterfall. ? The Pico supports hardware debug, so development could be relatively fast. ? A quick websearch revealed that there IS a working RA8875 library for the Pico. ? ? ? ? ? ? ? ? ? ? ? - Jerry, KF6VB -- Jack, W8TEE |

Re: [AmateurRadioBuilders] RP Pico 2
Check: Earlier Picos could be overclocked at 150MHz, but that overclocking often comes with caveats about doing that. Jack, W8TEE

Hi Jack, do you have any links where we can see that info about the *pi pico 2*? afaict, news has been released that the original Pi Pico has been bumped from 133MHz to 200MHz. I don’t see anything about the Pi Pico 2 though? Having said that, the Pi Pico 2 is interesting because… - it already clocks at 150MHz - it has FPU and DSP on the arm cores - is available as a ‘W’ version already (for about ?6.60 in the UK) with 4MB flash and 520KB RAM I won’t be surprised if a speed bump for Pico2 is announced later, but it has taken some time for that to come for Pico(original), and the Pico2 has not been out that long, so I guess we wait and see.

The Pico W has 26 I/O pins, 2Mb of Flash, and WiFi/Bluetooth support. No price was given for the Pico 2 nor did it say anything about WiFi/Bluetooth support, but the standard Pico W is about $8-$10.
