TLV320DAC3100 first bops 🔊🎶💃🕺

OK, after many hours spent with Claude on writing a driver for the TLV320DAC3100 (https://www.digikey.com/en/products/detail/texas-instruments/TLV320DAC3100IRHBR/2260591), we finally have it configured using our driver, and playing an MP3 stream on this ESP32. This I2S DAC has a particularly complex PLL and audio-routing system, so it's not one where you can just pipe in I2S data and have it magically play. One nice thing we got working on is the MCLK, which is generated from the BCLK, so it'll work great with anything from an Arduino-compatible to a single-board computer like Raspberry Pi. We're hoping to get the headphone detection working next so that we can turn off the amp when the headphone is plugged in. Also, it should be able to control the volume from the headset buttons. Also, we want to get the internal beep generator going so we can make tones separate from the audio stream for UI notifications.

building a robot helmet and i think

i think i can run doom on this thing

Cyberjacket update. Managed to get the interrupts working, meaning that I have functional buttons even with effects. I can now add as many effects as I have buttons, which is to say: a fucking lot.

New toy!

First time using an ESP32, so I only tried to run the example code tonight.

Given I’ve also been sleeping like 4 hours a day, I’m basically Rami Malek.

Espressif programmer test success! 💻✨🔧

While developing boards, there are oftentimes we want to program ESP chips without going through the onboard USB port; this adapter will help us (and others) do that! It has a CP2102N USB-serial chip

https://www.digikey.com/short/bm7n3p5z

...with RX/TX signal LEDs and two transistors wired up to the DTR/RTS line for the 'esptool standard' reset procedure technique. The output IO, plus a 3.3V 500mA regulated output, is available on a socket header, so you can plug wires in for quick programming and debugging. You can use this for everything from an ESP8266 up to the ESP32-P4! Here, we are testing it with a HUZZAH ESP8266 breakout board

...one of our first Espressif chipset products.

Giving a talk at the electronics hackers convention about hacking two different yet similar devices: smart sex toys and Bluetooth speakers.

You see, they both are made with many of the same components! 18650 batteries, ESP32 or Nordic Semi nRF microcontrollers, USB charging. You just plug a motor drive+vibration motor on the end, or you plug in a class-D amplifier chip and some speakers. But like 80% of the device is the same, we just put them in differently shaped cases.

It's at this point I pause to let these facts sink in.

And in the silence, the audience can finally hear it: a soft and muffled playback of Never Gonna Give You Up, coming from the stage.

About a month ago I decided to learn programming so I could level up my electronics journey, and am currently enjoying the roller coaster ride of learning to program microcontrollers. Although I have many ideas that I wish to develop, I first chose to co-create a magic mirror device with a witch named Eryk.

This is a small handheld electronic device that looks like a little scrying mirror, but when powered up, the mirror reveals a face that talks to you. You can ask it a yes or no question, which it will answer, and it has a divination mode, where you can ask a more specific question or obtain a general fortune.

I am still troubleshooting the hardware, which includes an ESP32, an OLED display and a DFPlayer mini. I started with an Arduino and a small OLED and everything was working well until I hit the memory limit of the Arduino. I upgraded to an ESP32, which I had to adjust my code to, and then decided to upgrade again to a slightly larger OLED. Along the way I somehow acquired almost as many electronic components as there are trees in my forest.

Ok, I feel like you could answer this: as processor designs iterate and use new technology and design paradigms, why don't we see more modern re-issues of lower spec processors? Wouldn't (or couldn't), say, a 68000 made with modern procedures and as small as we could make one now draw even less power than the original?

Thats generally because if a new processor is getting manufactured people are going to want more modern features so you'll get something with similar specs to an old processor but now it can do X cryptographic operation in a more optimized way or like you mentioned it draws less power or it gets smaller. There's interesting stuff that happens with that like you'll get a microprocessor with similar or greater specs so it's possible to run old programs off a microcontroller or something even smaller. For a practical example many ESP32 boards have better specs then an original GBA so people have kicked around different console designs with them. Including a console you may have heard of, The Playdate uses a STM32 and an ESP32 (though to be fair the ESP32 is used for communication primarily as far as I can tell)
