Re: Servo & I2C Timer issue
Author of ESP32Servo here. Take a look into the sensor and see if you can specify which timer to use. The ESP32Servo class will allocate timers in order, starting with 0. If that's not possible, before calling servo.begin(), call ``` ESP32PWM::timerCount[0]=4; ``` This should lock out timer channel...

Re: ESP32 WROOM-32
Humm. So you had an ESP32 and you replaced it with a ESP32 WROOM and you now expect to get more memory available but a ESP32 DEV is a ESP32 WROOM. If you want more ram from an ESP32 you'd want to go with a ESP32 WROVER. Many WROVER's come with 8+ MB ram. Using the Arduino IDE with a Wrover you can a...

Re: SPI driver corrupted GPIO39, GPIO36, GPIO34, GPIO35
https://docs.espressif.com/projects/esp ... /gpio.html
GPIO34-39 can only be set as input mode and do not have software pullup or pulldown functions.

Re: Blocking code to Non-Blocking help.
100% what he said^^^^^^^^^^^ I know complete waste of an ESP but that all I am using at the moment: #include "sdkconfig.h" #include "esp32/ulp.h" #include "driver/rtc_io.h" #include "esp_system.h" //This inclusion configures the peripherals in the ESP system. #include "freertos/FreeRTOS.h" #include ...

Re: store data in Flash (not Spiff)
One can use the EEPROM library to store data in flash.

Re: Restart if Guru Meditation Error
You might want to hunt down and install the "esp exception decoder arduino", it could provide some help with hunting down the issue.

Re: External ADC Question
Also, I found that by sampling the ADC regularly once a mS or so, and applying the Simple Kalman filter to the results https://github.com/denyssene/SimpleKalmanFilter , the output gets real smooth. Even if the A:D converter values are not displayed regularly, like once a second, getting several read...
