Long overdue blog post!
“But what if every button is also a screen?” That’s the question that started a multi-year project to build a custom electronic music production device, the SoundSlab. One glorious day it will be part sequencer, part sampler, part synthesizer, and part slab. Today it’s a never-ending hobby project…

It’s a relatively simple example for the SpinalHDL library I've been working on: spiny.
spinal/Blinky.scala defines the SoC, super short.
That definition auto-generates a SVD file, which is then fed to svd2rust to create a peripheral access crate (PAC). That gives nice Rusty strucs and methods for accessing all the registers. The rust firmware using it is in fw/src/main.rs.

I quite like ethernet on FPGAs. It's not that hard to implement, at least this simple case, and a cheap RGMII PHY gives you a gigabit connection with just some ODDRs and IDDRs. There might be a lot more ethernet in my future designs…

It's funny that we get so excited for some LEDs to turn on… but these LEDs mean a lot!
This is my first time lighting up LEDs by sending an ethernet packet to my soft SoC. All the SpinalHDL, auto SVD generation, auto Rust PAC generation, firmware, and timing constraints worked.
I've done a bunch of FPGA stuff before, even implementing my own HDMI RX in SpinalHDL without any vendor IP or wrappers on GTP transceivers. But, I've never gotten around to ethernet before now.

Разработка DIY компьютера на базе FPGA
Желание поиграть в проектирование собственного процессора обычно приводит к покупке платы с FPGA . Но мне захотелось сделать шаг дальше и начать не с Verilog-а, а с паяльника. Это статья о том, как я занялся разработкой электроники, не имея почти никакого опыта в этой сфере. Цель - сделать устройство с FPGA на котором можно загрузить Linux, подключить экран и клавиатуру, а потом прямо там писать и компилировать код. Зачем это нужно? Это хобби. Практической ценности не имеет. Просто я так развлекаюсь. А сейчас у меня, к моему собственному удивлению, все задуманное получилось, и я хочу показать и похвастаться.

Quanto è difficile disegnare un microprocessore capace di far funzionare Debian? Serve un esercito di ingegneri, o lo sforzo è alla portata di un singolo individuo?
Charles Papon è riuscito nell’impresa da solo! Per riuscirci ha creato #SpinalHDL, un linguaggio più astratto di Verilog e VHDL.
In questo video Charles Papon mostra il suo microprocessore in funzione su un FPGA e riesce persino a giocare a Doom!

@jemo07 Sadly I do not think that the onine #SpinalHDL webinar was recoreded. I will ask.

There is a free SpinalHDL webinar this weekend. It is my favorite HDL.

I now have a blinky running on my #picoice board generated using #SpinalHDL and APIO.
Getting the initial J!Sc running on a non supported board looks quie difficult because of all of its additional features.

Neues Spielzeug ist gestern angekommen: Ein Tang Nano 9k #FPGA #Development Board. Zusätzlich habe ich noch das passende 7" Display mit dazu bestellt. Werde mir dann wohl auch #SpinalHDL mal wieder anschauen.
