#Rust #audio / #teensy people: Does someone by any chance ever had made a library to interact with the PCM3168APAP chip or similar? :)

In general it seems https://github.com/mciantyre/teensy4-rs has no support for I2S yet. Am I correct there? :)

...and I thought to myself, "why not control LEDs with LEDs?!"

IBM PC 8088 replaced with a Motorola 68000 https://microcorelabs.wordpress.com/2023/04/28/ibm-pc-8088-replaced-with-a-motorola-68000/ #RetroComputing #teensy #hardware

Here a video of the old firmware running slow.

#Arduino
#Teensy

I updated the firmware in my meeting sign, it now accepts one packet with unique LED configuration for as many addressed LEDs as desired in the packet.

The result: near instantaneous update of all LEDs.

Like I said before: the most over-engineered light switch I've ever designed.

The code for the microcontroller is here if you want to take a look!

Are you someone in the Bay Area who owns an #Arduino #teensy 3.2 or 3.6, and would be willing to part with it? One of my students needs it for a really cool project and they are not easy to come by right now.

Just published Teensy64 firmware for Teensy 4.1 working as a drop-in 6510 replacement for C64 https://github.com/ytmytm/teensy64

In the fastest mode (none of memory accesses are passed to C64 bus) it's over 40x faster than a stock C64, twice the SCPU speed. This works somewhat like Amiga's fast/slow RAM. You need to write back data in synchronized mode to make it visible to VIC. But you don't need it always (e.g. after prg decrunching).

Finally I was able to publish my old project: modified firmware for Teensy 4.1-based replacement of 6510 CPU in C64.
Features include: software-controlled fast mode (only writes to I/O passed to system bus, up to 20x faster than stock C64), REU emulator, loading files from SD card (like Tapecart), USB serial console for remote debug in the future

Spent the morning wiring up a #teensy 3.5 to a #8051 core AT89S52. Mostly to do ISP (which is evidently "In System Programming" and not "In Situ Programming" like I thought) but also to do some debugging down the line.

Also wired up a 4-16 address circuit for decoding a full key matrix, and a few shift registers hooked to LEDs for verifying my output that will eventually go into a 6522 VIA in my #6502 #retrocomputing build.

Next up is a whole bunch of assembly programming to make it work.

#teensy #portableaudioplayer

A project to build a simple portable mp3 / flac player [0] using teensy and minimal monochrome lcd display.

The power/charge/batter boards work great and you can throw on any little portable battery, and charge from micro-usb.

There's an audio board with 3.5 inputs and a decent PCM.

There are mini sdcard storage boards, and they have persistent storage too i think.

I made a portable alarm clock that was most of this stuff [0].

Easy ! :P

[0] 90 percented it :)
