#mecrisp — Public Fediverse posts

I am happy to announce the FemtoMSP430, a processor designed with the instruction set of the classic #MSP430, but with a flexible bus interface similar to @BrunoLevy01 #FemtoRV32 including memory busy signaling. The playground contains a phantasy "microcontroller" design for the #ULX3S #FPGA board, interactively running the original #Mecrisp #Forth image for MSP430G2755, enhanced with a text mode on 800x600 video, USB-CDC terminal and a lot of GPIO wires: https://codeberg.org/Mecrisp/FemtoMSP430

I am happy to announce the release of a longwave software defined radio which I designed at work for experiments with #DSP algorithms, running on the #ULX3S #FPGA board. The user interface is based on #Mecrisp #Forth running on the #FemtoRV, and the signal chain contains a pipelined FFT designed by Dan Gisselquist. Many thanks to Ulixxe for their USB-CDC implementation!

I received an #upduino and a #picoice circuit board this week, got the basic tools working, and am working on an echo server. Soon I will be building a #Mecrisp #Forth core.

I am giving a talk on #Forth this week at the #fpgaworld conference in stockholm.

#ZeptoForth boots on the #PicoIce, which means that the default power, usb and flash pins are correctly connected. Which means that #MicroPython and #Mecrisp probably boot as well.

As soon as I get my #FPGA working on the #Upduino, I want to buy a Pico-Ice, and check out the REPLs..

I bought the #upduino board. $33 List Price. $97 shipped to Europe and taxed. And I still need some #pmods.

Now I feel like goofing off until it arrives.

I will be using th #Upduino board, not the #PicIce board. So much simpler, and it optionally comes with 4 pre-doldered headers (slots) for #pmods.

There is even a version of #Mecrisp which already runs on the Upduino.

And I can do all the development on my Mac!
