Re: Use ESP32 as WiFi dongle on raspberry pi

No, sorry, I don't think we have slave drivers for that at this moment.

Re: New to ESP32. Which one should I buy for my specified needs?

Configurable microinstructions is pretty uncommon for the main processor nowadays; I think that stopped happening around the time of the Xerox Alto. It seems to be something that's relegated to coprocessors nowadays. I agree, it would be fun to have. The way the flash is accessed is via a cache. Tha...

Re: New to ESP32. Which one should I buy for my specified needs?

You may read up a bit more on the ESP32 itself first, as you seem to have some ideas about it that only have a tenuous connection to what we actually create in silicon: - The ESP32 has an Xtensa controller, which has the option to define extra instructions. This happens at CPU design time, however; ...

Re: UART_NUM_2 printing characters to serial monitor not working

It depends on what you know you'll receive. If it's a standardized type of packet, you can write code to dissect it and display the various fields. If not, you can show it as hex using e.g. the ESP_LOG_BUFFER_HEX function.

Re: ESP32 http post example

Now I intend to port the whole thing to use a single PHP script that receives the SQL preformated command that is already in use by an Android app to read the same tables from the same database. I hope you don't intend on using this architecture for anything serious? Because it'll take only one scr...

Do you also have iperf running on your router?

Re: Maximum current per analog input

As the analog input is an (high-impedance) input, it will generally use a negligable amount of current. You can connect something to it that can source 6 or 12mA, or more, but it will never draw that much. I think you're confusing inputs and outputs: outputs can indeed source a limited amount of cur...

Re: Software Interrupts

I feel we may have an X-Y problem here. Can you tell us a bit more about the problem you're trying to solve, the problem you think a software interrupt is the solution to?

Re: wifi: rx ampdu: duplicated addba request, potential compitability bug

That sounds like a bug (or, best case scenario, some... creative spelling on the side of our engineers). Can I ask you to start an issue on Github for this, so we can look into this? It would probably also help if you could mention the mode (ap/sta) and what device you are connected to, if possible,...
