There is one more thing, the ESP32 takes 7 bit address for the I2C device. All the functions, which are included in the library of ESP32 will shift this address to the left by 1 bit, 0x27<<1, and the LSB here will be responsible forread(1)/ write(0)operation. If you plan to ...
Which GPIO pin can be used as an analog pin? And which pin should not be used to use this board safely? You will get the answer to these questions in this article. So now let’s begin with the introduction of GPIO pins of the ESP32 development board....
Maybe i misunderstood what you are trying to do, but I would use the 32kHz square wave output from the DS3231. You could keep a counter running at 32kHz interrupt on the ESP32 that is reset by the GPS pps signal. If it goes above the 32kHz count => gps pps signal is lost, re...

I think all you need to do is enable the USART global interrupt in the NVIC Settings (in CubeMX) and use the appropriate _IT() function (https://www.waveshare.com/wiki/STM32CubeMX_Tutorial_Series:_USART). I don’t think printf() works with receiving, though. I have not tried it,...
I work with ESP 32 (ESP-IDF) and try to detect a cause of interrupt - rising or falling edge. I know some ways to accomplish. So: 1. Use one GPIO configured as an interrupt emitter (rise and fall), after it we need to measure a voltage on GPIO (of course by ADC) - is not...
To set a custom hostname, we’ll use a string variable called “hostname” and assign the desired hostname value, such as “ESP32-MICRODIGISOFT-AP1.” You have the flexibility to choose a hostname that suits your needs. String hostname= "ESP32-MICRODIGISOFT-AP1"; ...
Re: How properly, under RTOS, to set up the highest priority non-maskable interrupt vector? Postbydjixon»Sun Apr 21, 2024 1:27 am ESP32-wroom-32E If you tried that project, in sdkconfig you can see that I turned all watchdog timers off. I thought that RTOS utilize those timers ...
