Github Copilot?

Anyone know if Espressif have Github Copilot enabled for their repos? I was wondering what help it might be writing a new ESP32 project.

Re: FatFS - how create a partition?

Thanks. The configuration includes some long strings (needed to provide authentication to connect to Microsoft Azure resources) which was why I was avoiding the "simpler" options. I expect this to mostly be one-time set-up with rare changes but I will look again at the SPIFFS stuff. As to the CSV fi...

FatFS - how create a partition?

My assumption is that using just an esp32-c3, I can create a partition and tun FatFS against it to store configuration (which will change very rarely). If this is correct, how do I go about creating the initial partition? I need to understand: 1. First time creation 2. How to avoid trashing it durin...

Connect IR photodiode to ESP32 RMT?

Can anyone point me at some circuits showing how to connect an IR photodiode (note a 2-pin photodiode not one of those fancy "photodiode plus decoding circuitry" 3-pin sensors) to the ESP32's RMT circuitry? I'm guessing something that boosts the photodiode's output is required - opamp? transistor? I...

Re: Current on input/lines line in deep-sleep?

@boarchuz Excellent - thanks for the suggestion of "pullUp/check/turn off pullUp"; sounds like exactly what I want. My earlier idea, where you said the power would only leak if the switch were closed, is a non-starter as the switch is closed about 10% of the time. The project is to monitor a rotatin...

Current on input/lines line in deep-sleep?

I am creating a battery driven project that I want to use minimal power so most of the time I am intending to deep-sleep the main processor and use the ULP to monitor an input line based on a second timer. My first "design" is: 1. Input line pulled up to 3.3V using 10kOhm 2. Input is also corrected ...

Logical AND of two DMA channels?

Is it possible to perform some sort of logical AND of two DMA channel? My use case is a high frequency "carrier" being turned on/off by a low frequency output [1]. [1] Yes, you can get low frequency DMA switching by being clever, for example running a clock 32 times faster than you want and encoding...
