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

Re: T41 V66.4 with Code Revisions
You've solved the problem with TX calibrate! One thing I have just noticed is that RF Out Atten seems to work in reverse. The higher the number the greater the output. Roger G8JWT

Its the original pico not the pico 2 that got the speed bump. Gary W9TD

Re: [AmateurRadioBuilders] RP Pico 2
I actually have a couple pico 2's. No wifi, though. 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

First impression is that 66.4 has cracked it. Thanks Roger G8JWT

Re: slow starting on T41 kit
The Main, RF, BPF, encoder boards, offset, etc are all public and part of the T41. MY K9HZ 20W PA, 100W PA, LPF, Antenna Tuner, etc are all my design that I sell for multiple radios in addition to the

Re: [AmateurRadioBuilders] RP Pico 2
Check: https://www.seeedstudio.com/Seeed-XIAO-RA4M1-p-5943.html Earlier Picos could be overclocked at 150MHz, but that overclocking often comes with caveats about doing that. Jack, W8TEE

Re: [AmateurRadioBuilders] RP Pico 2
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

Alternative to Pico?
All: I've also experimented with the XIAO processor from Seeed Studio. It's about the size of your thumbnail and costs $5: It has 256K of flash and 32K of SRAM with 19 general I/O pins, ADC/DAC pins.

Just looking at the T41 and K9HZ repos and I can't find the gerbers for either the normal encoder or dual encoder board. I already have the normal encoder board obviously but I am interested in

RP Pico 2
All: I just read that the RP Pico 2 is now capable of running at 200MHz, up from 133MHz earlier. Using CMake, the new speed setting in the compiler is a symbolic constant:
