Claude, port gr-fosphor to Android. 30min later...

Crazy times we live in..

First success with porting hsdaoh to the RP2350 HSTX: Streaming out 72 MByte/s from the Pico2 via HDMI to a $5 MS2130 capture dongle. Time to hook up an ADC!

After quite some reverse-engineering, the recent MS2130S-based capture dongles are now supported by hsdaoh: https://github.com/steve-m/hsdaoh/commit/13d832966bd95d44fcfb5295defc3efb5b232596

They completely changed the register layout and I had to figure out (again) how to enable raw YUV capture. The fun part was also extending emu8051 with code-banking support to be able to emulate the (now bigger) firmware. In theory raw RGB capture should be possible now, but this will take some more effort.

The first time I've seen GPLv1 licensed code in the wild so far...

Currently playing with Semtech SX1250 as SDR. 2 bit I/Q output @ 32 MHz. Has anyone already played with this chip? I know of https://github.com/M17-Project/SX1255_HAT-hw - but the SX1250 is newer and has a much broader freq range (150M - 960M).

If anyone wants to play around with the bit-banged 100 MBit/s Ethernet for the Pico, here you go: https://github.com/steve-m/Pico-100BASE-TX

Sometimes, Claude decides that he doesn't need an assembler...

Following up on my previous post, I'm pleased to release hsdaoh-rp2350, which includes an example application that streams the samples of a 12-bit ADC out of a Pico2 at 40 MS/s (or more!): https://github.com/steve-m/hsdaoh-rp2350
