Re: ESP32 IDF Linux and I2S

Your distortion and 'why do I need to write 4 bytes' is probably because you're confusing bytes and samples. Each sample is a 32-bit value. You have 256 of them (looking at your uint32_t sample[256] line). i2s_write_bytes, however, expects the samples and the sample length in *bytes*, however. (Why ...

Re: Crash on vRingbufferReturnItem

Can you see if you can get a backtrace from your code, either by running your crash to a backtrace decoder, using gdb, or re-crashing it but looking at the serial port using 'make monitor'?

Re: UART_PIN_NO_CHANGE

Esssentially, it means that the UART code should not touch any of the settings for that signal. If the signal already is routed to a pin in some fashion (e.g. by having manually tweaked the GPIO mux beforehand), it will stay there; if the signal is unconnected it will stay unconnected. Unless you sp...

Re: WiFi Lora 32 board and ESP-IDF

Code: Select all

rtc_clk: Possibly invalid CONFIG_ESP32_XTAL_FREQ setting (40MHz). Detected 26 MHz.
is on point; your board probably has a 26MH crystal but your project is configured for a 40MHz one. Run make menuconfig and go to components -> esp32-specifc -> main xtal frequency to change this.

Re: Regulator ESP32 Deep Sleep

For my personal projects, I like the HT7833. Not too expensive, has the 500mA output capacity I need, and sips 4uA quiescent current.

Leitukey: Again: your point is clear but offtopic and does not bear repetition in a location where we want a technical discussion to take place: I removed its contents.

Re: What would you like to see in The Next Chip?

I warned you in a PM that we do not accept offtopic ranting here: please keep to technical details. You have made your opinions about the direction you think Espressif is going in and your hopes/wishes/predictions re. our CEO loud and clear, no need to repeat them in every single post you make.
