ESP32-S3 not working with the CP2104

My ESP32-S3 will not upload and Arduino sketch using the CP2104. I double checked the Rx Tx lines from the S3 to the CP2104 and have a 10K pull-up on IO0 but none on IO45 that I believe is correct. Attached is the schematic and upload errors. If anyone has any idea, it would really help. I find it o...

Re: ESP32-C3 Serial.available() doesn't work over native USB - print, printf works fine

Uploading sketches and serial data worked so intermit and poorly for me that I ended up adding a CP2104 usb chip. After that it all worked perfectly. I was hoping after a few updates it would work better but nope.

ESP32 based Weather Data

This is a ESP32 based color E-INK display that wakes up every 15 minutes, grabs local weather data, formats and shows it on the display and then goes back to sleep. No idea how long it lasts on a tiny lipo battery yet but it's been running for a few days now. Sleep current is around 30uA or so. The ...

Arduino Deep Sleep with with timer wake up example issue

I'm having trouble with the Arduino deep sleep with timer wake up example code. On my hardware I've added a little led that is supposed to blink every 10 minutes. Right now it will wake up and blink for a few hours and then stay sleeping forever. The battery voltage remains fine during the entire te...

https://i.imgur.com/Y5G5UT7.jpg https://i.imgur.com/ej0gKEv.jpg This design was an experiment using an E-Ink display. Another PCB revision is on the way that should allowing it to be powered from a battery. Right now it can only be powered using a microUSB cable. The e-ink displays are 2.13" in siz...
