Aparently as suggested by Sudeep (https://github.com/espressif/esp-idf/is ... 1935791232) just need to remove ESP_INTR_FLAG_EDGE flag

You install the ISR before starting the task. This means that the ISR can trigger before TaskBTNReset is initalized.
1. No it cann't untill I press the button - I have pulldown.
2. Same error if I start task before interrupt init.

xTaskNotifyFromISR / xTaskNotifyWait pair causes error

Hi all, I want to make my ESP32-C3 to restart when I press button connected to GPIO4. Here is my code static TaskHandle_t taskBTNReset; static void IRAM_ATTR reset_button_isr_handler(void* arg) { xTaskNotifyFromISR( taskBTNReset, 0, eNoAction, NULL); } static void task_btn_reset(void* param) { print...

Re: ESP32-PICO-D4 and 1.8V

Yes, that's what I thought. Thanks for confirming.
Since I'll be the first who's trying will update here about results :)

The GPIOs that you mentioned are 5, 18, 21, 22 and 23. Right?

ESP32-PICO-D4 and 1.8V

Hi all,

I'm want to connect ESP32-PICO-D4 to 1.8V peripheral but I'm a bit confused.

Is it possible to provide 3.3V only for VDDA and VDDA3P3 and 1.8V to VDD3P3_CPU so that GPIO's be 1.8V ?

ESP32-WROOM(U): connecting external PSRAM

Hi, Acctording to menuconfig ESP32 supports two ttypes of PSRAM: IS25WP032 and LY68L6400. I didn't find where to by the second one so I decided to use the first one but obviously in 3.3V version (IS25 L P032) since i'm connecting to to 3.3V ESP32 module. Particularly IS25LP032D-JKLE ( PDF ) So far I...

What is the purpose of VDD3P3_RTC pin in ESP32-PICO-D4 ?

I want to understand how to keep RTC clock working while chip logic is off(if possible)

if I connect VDD3P3_RTC to 3.3V supercapacitor/battery would it be enough? Do I need also to provide 3.3V to CHIP_PU?

Optimal configuration for https client

I have simple web-site base on Apache with SSL based on self-signed certificate. And I want to write simple https client much like the one from examples. What are the optimal parameters in menuconfig to reduce memory use as much as possible? Because right know SSL subsystem eats about 80K of RAM (e....

Format SD-card connected through SPI

Hi all, I guess one feature is missed in SD API - ability to format it ;) I tried to use peace of code from IDF ( esp_vfs_fat_sdmmc_mount function): void *workbuf = malloc(4096); DWORD plist[] = {100, 0, 0, 0}; int ret = f_fdisk(0, plist, workbuf); ret = f_mkfs("/sdcard", FM_ANY | FM_FAT32, 16*1024,...
