Re: AP Mode - esp_wifi_set_config throwing error
Hi, you should run 'esp_netif_init()' prior to calling 'ESP_ERROR_CHECK(esp_event_handler_register(WIFI_EVENT, ESP_EVENT_ANY_ID, &wifi_event_handler, NULL));' the should fix the problem.

Re: Any good books using Espressif tools?
Hi. If you know what you are doing, these are official Espressif documents useful for low-level programming & design: Xtensa instruction set.pdf - https://0x04.net/~mwk/doc/xtensa.pdf Technical Reference Manual.pdf - https://www.espressif.com/sites/default/files/documentation/esp32_technical_referen...

Re: MCPWM does not want to start
You are right. The dump shows that the mcpwm timer0's configuration registers hold their values, so that particular part of the chip is turned on correctly. But timer0 status register shows a value that would not be there, if the circuitry was running. What you need to do is to set up RTC_CNTL_CLK_C...

Re: What ESP32 has the most amount of free GPIO ?
This is for example pinout diagram for ESP-WROOM32 (my little creation :) ). Keep in mind that GPIO 6, 7, 8, 9, 10 and 11 are used for UART communication via USB and GPIO0 has special purpose during bootup - when held low as the chip is reset or it gets powered up, special program starts up in the p...

[SOLVED] MCPWM does not want to start
Hello, here is the deal: I have made a simple C environment where I can run bare-metal code. I wanted to configure mcpwm peripheral to control an H-Bridge for 2 coils stepper motor. Used Chip is ESP32-D0WDQ6 (revision 1). The problem is that when I call two_phase_init(); , the registers hold their v...
