Hello developers I need help setting up servo motor with ESP32 s2. Will discuss more details in chat. Thanks.

Hi Deep K., Hi Deep K., I'm looking for someone to help me with my project I'm doing on an ESP32 using WIFI AP and ESPNOW with a WEBSERVER interface 1. Communications of all ESP32s from the ESPNOW network to each other on events such as trigger input. 2. Communications between ESPNOW network and Webserver on a MASTER ESP32 now it only works in one direction so the master sends signals they execute but I have no tracing of the execution. 3. Interfacing with Android smartphone APP you should help me receive external inputs via WIFI server and respond to the execution of the required processes. Kind regards Philip

Need someone Expert for ESP32 BLE to optimize our BLE code for Final production produce. We want to ensure flawless BLE working.

Code need to work on Arduino IDE with espressif/arduino-esp32 1.0.6 I need to detect a very fast pulse end moment (10-15ms lenght) but since ESP32 takes +200ms to start up, it's must be done from wake stubs 1. Esp32 it's in deep sleep or hibernation mode 2. HIGH pulse interrupt and wake up 3. Wake stub looking for LOW/Falling 4. Wake stub detect LOW/Falling , take the time into variable and wake up as normal 5. Normal operation, print how many microseconds elapesed from LOW time Note: Your stub code must be boot up in less 10ms, otherwise it will not be able to capture the moment from HIGH to LOW Use what ever gpio number for interrupt (DEVKIT-C) Image included for better understanding

The project consists in writing professional code to flash into an ESP32 development board. Specifications: The code must be able to make the board perform the following tasks: - Connect via Bluetooth with a phone or other device (laptop or tablet) and configure the wifi settings to let the board connect to the internet. o It must be possible to configure this page with a personalized logo and background - Once the Wifi has been set, the board shall remain connected to the chosen wifi network, and if the connection is lost, it should be able to try connecting again at regular intervals until the connection is restored - If, for some reason, the board freezes or goes idle, it has to be able to reset by itself, looking again for the connection Additional conditions: - The code m...

Hi, We already have a working recorder which saves wav files to an SD card (CPU already reduced to 80Mhz). Worked great but we need to lower the power consumption (Now: 30mA). I wish to get less than 5mA. Hardware: Digital mic (I2S or PDM) and SD card connected to a ESP32 I am pretty sure it is possible to record wav files in light sleep mode. Here is what i have in mind using I2S in the example. But not 100% sure if that works: - In light sleep mode the I2S interface writes data from the I2S microphone to a buffer (I hope that DMA or any other memory is accessible) - A timer wakes up the main CPU when the buffer is full which writes the data to the SD card - I2S and the main CPU can't have access to the same buffer at the same time. So once the timer triggered. I2S starts ...

I am the CEO of PeakProductDevelopment and we are building the IoT system. The prototype was completed. We need the full stack engineer with strong experience in EasyEDA and ESP-IDF to update the existing hardware. The system will be upgraded and the engineer need to work on developing other modules. The product uses ESP32-C3 MCU and TB6600 stepper motor driver. And the firmware is developed by ESP-IDF.

A hardware development is required. Sensor used for input: piezoelectric Microcontroller used to receive the amplified sound: ESP32. Output voltage range: 0-3.3V. Midpoint Bias near V=1.65V Operational Amplifier model: we will define it before start the project. Battery used: 1x3.7V or 1x9V Software to use: KiCad. Any other software for simulate it (for example LTspice).

Hi I am searching Esp32 programmer on esp tool for programming Connect me first then we will discuss non project

I made an ESP32 receiver-webserver program (ESP-now protocol in Arduino IDE) but what is missing from my code is the following: I want when we make a refresh on the receiver's webpage the data to be preserved (imagine that 10 senders for example send each of them just a string as their own id for being recognized by the receiver and a char message like "free" or "duty" which make the corresponding region-square for the particular sender green (free) or red (duty) on receiver's webpage. What now happens is: If I refresh the page all the squares start from green. I thought as a solution: the senders to send every for example 30sec the last message that they have sent but that means the senders all the time are awaken up (via timer) so as to send again the...

Help me "translate" this library: from Arduino Due to ESP32 I have few Tesla batteries with the integrated BMS, also the connectors, etc, so I can test the setup in real time. However, I do not have the know-how to port this library to the ESP32. I would need most importantly at least the following functionality: - read each "cell" voltage from the battery module (7S) - read the temperature - read the fault codes (if any) - start/stop the balancing Please read the description on the github page, also there are several hints here: Thanks! best regards,
