A New Life For An Old Amplifier

An audio amplifier was once a fairly simple analogue device, but in recent decades a typical home entertainment amplifier will have expanded to include many digital functions. When these break they…

@hexaheximal @nixfreak well, yes and no.

#BadUpdate is a "#tethered" exploit and it only allows running games and unsigned code. You can run #Homebrew and custom launchers this way but that's not gonna help re: #OS1337!

  • It does not replace #RGH3 as "hard mod" (which nowadays is chipless and only requires a #PiPico for #flashing in return, and that's needed for #XeLL aka "Xenon Linux Loader" to run #Linux on the #Xbox360.

Including the #Free60 Live-DVD!

I’ve been doing some embedded Rust on a Pi Pico. I’ve written a custom panic handler that will repeatedly flash the onboard LED on and off, which has been super helpful to see when something has gone wrong.
It has been thinking though, it would be cool if the panic message could be transmitted by these flashes in a way that I could decode on my mobile phone.
Morse code would be one option, but presumably I could do something better.. 🤔

Made some progress on prototyping a #RP2040 based #USB Audio interface. I got a PIO program to output a good looking TDM signal for 4 channels of 32-bit samples.

Now I can start prototyping the receiving end of the transaction, DMAing samples into RAM and packing them into isochronous USB packets.

What can I say.. Lots.

* Raspberry PI (#PiPico', freely documented and with open source toolchains)
* Expressif (#esp32, ESP-IDF is quite open, and there are other fully open source toolchains. Documented by everyone, everwhere.. :-) )
* #WCH, makers of the infamous WCH-CHV 1cent 32bit risc-v mcu are growing, and their ecosystem seems to be developing nicely. Mostly in China but a lot of that ends up getting translated.
* #stmicro; mostly propitiatory tools, but also open source alternatives and a very healthy ecosystem in industrial circles.
* Others that I am forgetting about, the #8050 is still popular, for instance.
* And, weirdly; #Arduino (forked). There are huge chunks of their ecosystem that are already fully open source and qualcomm cannot touch.

If you’ve written a Windows application that can read the Serial Number/Unique ID, or even the Vendor ID or Product ID of a microcontroller board (Pi Pico in my case) I’d appreciate any pointers.

I want to learn about this pattern where you write to a video memory area and then that gets processed separately and displayed on a monitor or VGA or what not. Maybe even something like what the #GameBoy does where tile maps and blit is done separately based on what you wrote to the video memory region. Does anyone know of any resources to implement something like that with #PiPico or #Arduino?

Two microcontrollers, where one writes directly into the other's memory, and the other does whatever processing and outputs video? I don't know if this is necessarily something practical I need to do, but I'd like to learn more about it. I've been reading about using DMA to communicate via SPI or UART and it reminded me of this.
