Re: ESP32S3 Problem uploading after selecting the wrong board type.

Yes normal way of getting into download mode has been tried. I don't have any PSRAM on my board and I don't think there is any on the esp32s3-mini-1-n8

ESP32S3 Problem uploading after selecting the wrong board type.

Hi, Uploading via USB worked just fine. I think I messed up by programming one of the eFuses "unintentionally". I have been struggling a little with my customboard where I'm having issues with GPIO pins 4-10 in general. Since I didn't create a custom board definitions file I went with the Lolin S3-m...

Re: Custom ESP32s3 board and GPIO issues

@ok-home I'm actually using the https://cdn-shop.adafruit.com/product-files/5311/esp32-s3-mini-1_mini-1u_datasheet_en.pdf mini-1 and it only has a single VDD pin that probably supplies the one you just referred to. This is so strange. I'll try and configure most pins as outputs and toggle all of the...

Custom ESP32s3 board and GPIO issues

Designed a custom board around the DevKit schematic and "most things work"... What I cannot get working is PWM on GPIO's 8-10 (pin 12-14). Connected to a LED it flickers all the time. Tried to understand if those pins are used internally somehow... Using the ESP32-S3-MINI-1-N8. I have verified on a ...

Custom ESP32 Pico board fails to go to programming mode using auto reset

Hi! Built a couple of boards using the ESP32-WROOM-32D. Now I'm using the PiCO version with a new layout and also choose new NPN transistors in a smaller package to make the autoreset circuit smaller. Made a good decisions to keep the buttons on there just in case. So I can use the buttons to get it...

Re: I2S Pins

Thanks for responding ESP_Sprite! I'm connecting two MEMS microphones basically doing ADC but I guess the same applies? MEMS Mic have been set to alternate left and right channel using the same clock signal. But a lot of example on the internet uses this MEMS mic. And... Not using external ADC/DAC's...

I2S Pins

Hi! Naively put together a board using examples on the internet and looking at a few reference designs. I'm still struggling to understand the required pins to get this working. GPIO25/26 are listed as DAC1/2 ... There are two I2S channels. My thinking was that GPIO25/26 was required for the actual ...
