I got a voltage adjuster (one with the screw to adjust output). Because of the dropout, i swapped the charger for one from a portable power bank, so it outputs 5v, which the adjuster outputs about 3.2v to the rest of the circuit now, although im still not getting sound output Edit: not sure what i d...

The chip is a esp32-wroom (not sure if it makes a difference). Ill look into a ldo with a dropout of around 0.4v, so it will be well within the 2.6-3.6v range

My wiring is messy, but this is currently the setup I have http://i.imgur.com/SuFHu6J.png I'm aware the higher voltage could damage the ESP32, but I want to test that it works with this setup. I tried a voltage divider with a 100k resistor and a 470k resistor, which should have put it in a safe rang...

Well, i have the esp32 wired to an sd card reader, a battery, and a piezo speaker. The battery is also connected to a switch, and lipo charger, my multimeter said it gave around 3.7v iirc. The vcc of the esp and sdcard reader are connected, as well as the ground for the sd card reader, esp, and the ...

Im making a music player. I use the batch burn board, so that i can program the bare esp32 chip. I finished the music player, and tested it through the board, it works well. I soldered everingthing to the bare board now, added a lipo battery and switch, and no sound comes out. Strangely enough, if i...

You can use the I2S driver from esp-idf; that makes the I2S peripheral handle all the timing and allows you to just push (blocks of) audio samples into it which then come out of the DAC or an attached I2S codec. Pretty sure the ESP32 can do what you want pretty easily, by the way: with an ESP32 at ...

Hi, I'm currently porting my code of "gameboyNano" to ESP32. This is basically a program that emulates the Pokemon Crystal music format, and streams it using the PWM pin. I was able to get the arduino running it at around 8Khz or so, although now I have it running on my ESP32, and it's still around ...

Is there a good place to start with this? I've worked with ASM in the past, mostly for gameboy and ARM

Hi, I'm brand new here. I have been using arduino for projects, and recently invested in an ESP32 Wroom, for the extra power. Right now, I want to interface the ESP32 with a gameboy, I made a cartridge with all 32 pins hooked up to a breadboard. From what I read, the CLK pin runs at 1MHZ, which is w...
