@rc2014 Also wanted to say the new VGA Terminal board is worth it... Works so well and the menu to configure it is quite nice.

CPU from 1978, and the VGA Terminal board; both boards from @rc2014 for the

Looking forward to slowing down the clock board and seeing if this old CPU fires up...

It’s totally normal to know which frames of Badapple are a pain to run length encode, right? (Video of an playing Badapple over HDMI shaped DVI coming soon…)

"I2C is an ubiquitous serial bus first described in the Dead Sea Scrolls, and later used by Philips Semiconductor."

Nice snark in data sheet, not sure how I missed that one before. Well played.

CTCSS tone generator for my old Expert4 #23 FM-Transmitter in test setup.

Hardware is based on a Seed-Studio XIAO board, using PDM via PIO and a simple RC low pass.

Today I have discovered , an ISA soundcard for DOS PCs powered by a Raspberry Pi Pico. The amount of hardware hacking going on these days is incredible. Microcontrollers were a great idea.

En conclusion, ce fut un projet intéressant. Il y avait sûrement moyen d’utiliser le différemment pour obtenir un résultat similaire, d’autres l’ont fait. J’aurais pu mettre de côté tout le rééchantillonnage et faire varier la fréquences avec l’horloge du µC, avec les limites que ça implique.

Voici Picogen assemblé et monté. Les étiquettes sont probablement provisoires, en attendant de trouver mieux (et la motivation de le réaliser). J’ai pu faire quelques tests, cette fois-ci sur une interface audio plutôt que sur l’oscilloscope. Globalement je suis satisfait du résultat, sauf peut-être au sujet de la distorsion harmonique qui demeure significative.

Je détaille ça dans les messages suivants. 🧵

So what's the big appeal of an over the family of chips out there?

Just being able to brute force bitbang whatever you want?

IT LIVES!

Please welcome to the world the , a USB SSD Drive using a .

This works with the SSDs that were used with the SIBO range of computers, including the Series 3 and MC400.

This prototype can only be used to dump SSDs, but future versions of the firmware will let you write to RAM SSDs, and future versions of the board will let you write to Flash SSDs.

A bit of Sunday morning fun implementing a PIO frequency counter on - works very nicely and allows for some long counting. Also allowed me to implement HCF on PIO which was mildly pleasing.

TL;DR turns out that even crystal clocks vary quite a bit - as much as half a second a day - which gets me wondering what you do for a _really_ accurate time base? GPS receiver?

Brunelles is my new guitar pedal project made around some spare parts. This is a kind of upgrade of my Aelis platform (based on the Spin FV-1 DSP).

Controls:
– Rotary encoder + switch
– Endless potentiometer
– 128×64 OLED display
– Footswitch + LED

Features:
– µC: XIAO
– Codec: CS4272 (or 71)
– True bypass

It’s the first time I use mostly SMD components. I’m not very happy with the routing but I have to start somewhere.

I am trying to make two RaspberryPi Pico talk UART with each other, but their serial port sends nothing in the configured pins, even when I wait until the TX buffer is empty.

I am using the HAL in rust, with the code in github.com/nils-van-zuijlen/sp

The UART peripheral gets configured in main.rs, the data sending gets done in parser.rs

J'essaye de faire communiquer entre elles deux RaspberryPi Pico en UART, mais leur port série n'envoie rien sur les pins, même une fois que le buffer d'envoi est vidé.

J'utilise la HAL en rust, avec le code qui est dans github.com/nils-van-zuijlen/sp

Le périphérique UART est configuré dans main.rs, l'envoi de données est fait dans parser.rs

Lost several hours of my life tracking down a weird bug where an based USB device wasn't recognised by the One. I eventually solved it by shortening the product name. The limit is supposed to be 31 characters, but the MPC doesn't seem to like more than 10. I think there's more to this bug than just the length, though.
