Re: Please help me with ESP32 Guru meditation error core 0

Any chance you can decode that backtrace? That should tell you exactly what line crashed here. Enabling gdbstub in 'make menuconfig' and using 'make monitor' would normally also be a big help, but I'm not sure if the PlatformIO/VS combo can do that.

Re: UART 'realtime' processing

The UART uses a receive FIFO; it normally stores some data there and only interrupts the main CPU once either the FIFO gets full-ish or some time with no transmission passes. You should be able to configure the 'full' threshold to 1 character using uart_intr_config(), if I'm not mistaken that should...

Re: How to introduce sequential tasks using xEventgroupSync()

Hard to say without knowing what your architecture is... can you explain a bit more about what you're trying to do and in which way you think you'd need synchronization?

Edit: Moving to General Discussion as this is not hardware-related.

Re: getting wrong values from xQueueReceive

What code do you use to create your queue? Perhaps the item size there is too small.

Re: Rust ESP32 - Xtensa startup

It can be configurable, and the configuration we use should be specified in a bunch of defines somewhere. (Don't know where in the LLVM tree, but in esp-idf it's here: https://github.com/espressif/esp-idf/tree/master/components/esp32/include/xtensa/config). It can also be extendable with custom inst...

Re: Changing I2C pins

GPIO 16 and 17 are used by the PSRAM on -Wrover modules and as such not available externally. Please pick different ones.

Re: Need help for ESP32-SOLO-1 module

Re: ESP32-WROOM-32 Freezing

Can you show your schematic? It may be that the relay is influencing the ESP32 through voltage dips or EMI or something.
