Re: ESP32-Wrover doesn't flash

Ok, I assumed, that I can also just pull GPIO0 to low, when I power the chip. I will try, pulling also Enable on low.

ESP32-Wrover doesn't flash

Hello all, I'm a bit clueless, about my project. The problem is, that I can't flash my ESP, even worse, I can't communicate with it, e.g. esptool.py chip_id is not working, then I get the error "All of the 4 available serial ports could not connect to a Espressif device." So in my eyes, for this com...

Maybe we can work together on the bidirectional DSHOT. Because the ESP32 has too few UART's :

Re: DShot Implementation

Thank u all for u'r suggestions. Found the problem. I was saving the BaudRate, which needs to be 600k in a uint16_t. Thus, the uart couldn't keep up with the interrupt, causing the crash. I found it by using a oszilloscope and looking on the exact timings. Furthermore, I tested the protocol for the ...

DShot Implementation

First of all, hello forum, it's my first post here. Maybe some of u will know, what DShot is, some not. DShot is a digital protocol to communicate with ESC's (electronic speed controller). Sadly there is no official document, but this is the best description i found: https://dmrlawson.co.uk/index.ph...
