Esp32 uart example Jobs

Connect an lcd display to a esp32, and a vs1053 board along with a lithium battery for a project. I also need appropiate code so that the esp32 can communicate with the display properly, and a system by which the vs1053 can send audio to an app. The app will analyze the audio and send back results to the esp32 and the display more details can be given. I can provide and send materials for the project. I already have a display, a battery, the esp32, the vs1053, and some connectors. Anything else I can buy, as long as it's relatively inexpensive. All I need is a functioning prototype and a possible cad design of the final device.

Hello, I need an Embedded software developer on the ESP32 to write an Ethernet Library, based on the official esp32-arduino Ethernet Library, to support for a custom RF module. The RF module is connected to the ESP32 through the RMII interface and SPI (for configuration). There is an already existing driver but for the STM32, transmiting data in Ethernet frame format, as SDIO host in SPI mode driver. Deliverables: - Source code for the esp32-arduino Ethernet Library for the RF Module - Example code - Documentation Candidates should have strong development experience on the ESP32 and on writing Ethernet libraries. Thank you

The aim of the project is to control the barrier mechanism at the entrance& exit gates of the sparking...the parking slot through a mobile app GUI like a flutter. The reason for that is to make a parking more smarter by pre-booking for the app, navigation helps them to find where they parked and payment. Controlling the barrier since uncertain behaviors can happen like leaving the car all day at the slot which is annoying others. Required for me to have the hardware: A microcontroller such as ESP32 / Arduino / servo motors / Leds / LCD and a space for a parking slot. Software: A GUI with features such as ( booking own slot in real-time, Navigation, and payment, and might more) I would like to hear from you very soon. Thanks For those who stay in Malaysia, Kuala Lumpu...

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

...the ESP32-S3 module with a USB port for a project. The ESP32 should boot from its flash and first detect if there is a USB pendrive plugged into it. If so it should copy two files - the executable file and the .HTML file from the pendrive to its flash. Then it should reboot, obviously now ignoring the pendrive and run a HTTPs secure webserver over WiFI in AP (access point) mode. Once a user logs in, the HTML file (about 250k) is served to the user, along with the application data from a 16384 byte RAM array on the ESP32 using the Websocket API. Changes made on the webpage by the user, usually using an Android tablet, also using the WebSocket API are stored in the RAM array, and also sent over the SPI bus to the rest of the system. At powerdown, indicated o...

Hi, I'm looking for a freelancer to help us design and build an ESP32-based Cube for home safety and monitoring.

The image data is written into the FPGA, and then the image is processed by adding an effect, such as blur, darken, or something similar. The user selects a specific switch to choose which effect to apply. The processed image data is returned to the computer, and this data can be converted to BMP format to see the final result. It would be desirable to use the UART protocol. I am willing to pay $120 for this project. If you are interested, please let me know and we can discuss the details. Th...

I have some code that needs to be enhanced, it is written in flutter

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
