convert ADC readings
Hi, I'm trying to measure input voltage by adc1 in range 0 - 3,3 V. This is how I expected to convert raw values to voltage: adc_input_voltage = (Vref * adc_RAW ) / 4096 and here is part code & settings: float convert_adc_to_voltage(uint32_t adc_val) { float adc_volt = (3.3 * adc_val) / 4096; return...

Re: Flashing ESP32 without buttons? (CTS RTS at uart dongle)
Hi, sorry for late delay with answer. Recently I got new esp core board and it flashing automaticaly without issues. :) But now I'm interesting, is it possible to flash automatically bare ESP-WROOM-32 module using only CTS and RTS pins? I have checked schematic of coreboard. https://dl.espressif.com...

Re: Flashing ESP32 without buttons? (CTS RTS at uart dongle)
Well, I'm dont have such capasitor onhand right now, I will try it later. Aslo, I noticed, that there is one more solution in topic - changing time.sleep() to 0.5 in line 352. I tried, by Eclipse says: File "D:/ESP32/esp-idf/components/esptool_py/esptool/esptool.py", line 352 time.sleep(0.5) ^ Inden...

Re: Flashing ESP32 without buttons? (CTS RTS at uart dongle)
Yes, this is my ESP32 board.
I'm using Eclipse and when I'm trying load projects, I need firstly hold BOOT and then restart module (press EN). ESP runs in boot-mode.
Overwise eslipse cant load firmware.
Should I edit esptool.py or change something in eclipse settings?

Hi, I have ESP32-Core-board-v2 kit and FTDI uart converter. http://www.mini-tech.com.ua/image/cache/data/programmers/ft232rl_red-550x550.jpg How can I use RTS and CTS pins to automatize a little flashing process? I want esp can enter in boot mode via remote access (let say, I leaved it in one place ...

GPIO remapping issue (peripheral doesnt work on certain pins)
Hi, I have issue with GPIO pins remapping. I tried official idf example of i2c peripheral on ESP32 DevKit: https://github.com/espressif/esp-idf/tree/master/examples/peripherals/i2c It works fine, but when I tried to change to another GPIO pin (i.e: in this section #define I2C_EXAMPLE_MASTER_SCL_IO 1...

Re: A very basic WebSocket Server
Hi,
I have little issue with this example.
Am I correct that some includes missing?
UPD:
need to add
#include "lwip/API.h"
in WebSocket_Task.c
