Need help of an expert on ESP32 ! I Have a working program running on an ESP32 on a single core. Would like to separate functions to separate cores and have both functions Run simultaneously without affecting each other. I’m using a ESP32 Wemos mini D1 module. Here is the list of parts used on the project: - ESP32 Wemos mini D1 module - RS485 module - sd card module - RTC Module Esp32 is used to run: - Webserver - Wifi - Run Functions from the sketch RS485 module is used for communication between esp32 and Sensor SD card module is used to store data from the sensor RTC module is used to keep track of time.

I have implemented a simple websocket echo server and a corresponding client that runs on separate esp32s3’s and communicate via wifi and it works. However the performance is very poor (~ 500ms for a roundtrip) so what I need is a optimization giving ~50ms roundtrip times. I have also implemented a python client and tested it against the esp32 server with good results (1000 roundtrips): Number of echos over 50 millies: 999 Number of echos over 75 millies: 40 Number of echos over 100 millies: 29 Number of echos over 150 millies: 13 Number of echos over 200 millies: 8 Number of echos over 250 millies: 8 Number of echos over 300 millies: 5 And I need the same performance with a client implemented in C/ESP-IDF. I’m using ESP-IDF 5.0.1 and the sources are attached.

Hello, I need to create pictures based on the example. I need more or less the same picture but with a different graphic design and colors. I need 2 pictures, one picture of Clitoris as in picture A, with the same structure but with colors and graphic style similar to picture B. The second picture is a comparison of the penis and clitoris as in picture C. The designs need to be done from scratch and have unique designs! PLEASE DON'T SEND THE SAME PICTURE CHANGED BY USING SOME FILTERS etc. DO THE WHOLE DESIGNEE FROM THE SCRATCH! I will ask you for the vector.

We are a small company with a custom board based on the T... During prototype revisions we've been running with Linux kernel 4.14 kernel provided by in the TI-SDK. With 4.14 going End-Of-Life in Jan 2024, we want to migrate to Linux kernel 5.10. I have been trying to bring the board up on the latest SDK/5.10 Kernel with difficulties. Although the board boots and we have serial communication, there are issues with the peripheral devices (ethernet, pinmux gpio, etc) I attribute to DTS changes in the SDK and kernel differences. We no longer employ someone with this skillset. We are looking to outsource the migration to the latest SDK. The latest TI-SDK contains, • U-boot 2021.01 • Linux kernel 5.10.100 • gcc-x86-arm-9.2-2019.12 toolchain ref:

Just a note I will not be using an on chip MCU. Lastly, as mentioned, I am wondering if there is a scenario in which I don't need to use HX711. Here's my reasoning: The Bluetooth chip ATBTLC1000A, has two pins called "configurable mixed-signal GPIO" ; they are pins 17 and 18. Since they accept Analog data, I was wondering if I could just directly connect it to my Wheatstone bridge and skip using HX711. Will ...

Hi, My hardware: ESP32 with an I2S microphone ICS-43434 connected. I have a firmware1 for ESP32 which records sound in very bad quality. So the microphone is not compatible with the driver in this firmware. I have another firmware2 which records sound from the same microphone in very good quality. So this I2S driver works perfect from firmware2. I need to get firmware1 running with good sound quality recording. And hope you can do that for me. Here is firmware1: And firmware2 (with good sound): I think the problematic file in firmware one is this:

The thermometer is is a Fine Offset WH2/FT007TH. In order to offload the ESP32 it might be better to use a integrated receiver like RFM69 or CC1101 instead of RXB6 simple superheterodyne receiver. However if the ESP32-C3 has enough power for all tasks, the RXB6 will be fine too. The wireless protocol is documented here: Data needed from sensor: -Sensor ID (1-8) -Temperature in celcius with decimal -Humidity Defined variables: -SSID -Password -HTTP_POST_URL -API_KEY When packet with valid CRC is received: -Make HTTPS POST: key=test&ch=channel&tmp=temperature&hum=humidity -Implement timeout for HTTPS POST (so it will not hang if internet is offline) -Print received data to terminal with result for HTTP POST (OK/ERROR) Code

Hi i want to communicate between multiple slaves with single master with esp32 arduino

Hi Dean E., I noticed you planned on adding a design for my solar charging contest. Most designs i got from others have big flaws or are just copies from chatGPT. So I came up with my own design and hope you can evaluate it and build it together with me? I have already done most of the component research. I just need someone who knows what he is doing because i am just a hobbyist. Can you help me with that and you will get the 50USD from the contest. Is that Okay for you?

...engineers that have experience in ESP32 and ESP-Now protocol. I have made a network of many ESP32 devices which send a few data to a receiver-webserver (STA mode). So let suppose we have n number of senders and one only receiver-webserver with name "x". What I want is to increase the range. What I thought as a solution is to put between the n senders and the receiver "x" another ESP32 device that will act as receiver-sender. It will receive the data from all the n senders and immediately will send this data to the receiver-webserver "x". Only 1 day committed engineers to finish the job. The range and the limited number of nodes (20) are the most important "cos" of the ESP-Now. If you have any other solution for increas...
