Hi, I have this issue(cited above): This is 1 external i2c driver (called SmartDrive) After I create a i2c driver I will use LVGL and will be pressed to run motor 01 (right and left). The same will apply to engine number 02. I have this driver in c/c++ And in Java But (as reported in the st electronics community) it needs some changes to work on the stm32f469 discovery kit
The scope is to design a testbed utilizing the ESP32s3 chip (8MB RAM 32MB Flash version). Peripherals will be screen, 24 tik encoder, speaker/ buzzer, tactile switch. CAD is is attached along with component specs and data sheets. requirements for acceptance: design on Altium 19+ access to a FAB and components. Able to do their own debug and testing familiar with the ESP32 SOC family - EE design and firmware
Hi, I'm looking for potential support at weekly or monthly rate for general support in electrotech. The work may consist of programming (Arduino C/C++), electronic design and customer support. Kicad and C/C++ microcontrolers (ESP32) work would be necessary. Work can include Arduino IDE and Beagle board hardware devices. This is a full time job for periods, please quote weekly or monthly at your will. Regards Jean-François
Need someone to add 2 pretty simple feature to our existing POS esp32 firmware. 1. Turn wifi strengt up to maximum strength. 2. Make the device restart when WIFI connection is lost for more than 120 seconds. Thats it, should be a relatively simple task for someone with esp32/ Arduino experience. Dont bid less to get the project, WHAT YOU BID IS WHAT YOU GET NO MORE!
I'm looking for a high school student or a university student to help me build an Internet of things (IoT) device using MicroPython on the ESP32. (ESP32 is a microcontroller just like Arduino). You need to live in the Western Balkans, Eastern Europe, or Latin America. Why don't you need any experience? I would rather work with someone who is inexperienced yet very intelligent, rather than someone who is experienced yet not very intelligent. You need to be able to work five days each week for one hour each day. You may choose the five days that are convenient for you. You may work at any hour of the day (or night) that you prefer.
I have a 10x10 board with the following part: 5 holes for small sensors, 2 USB ports, keypad, small OLED screen, 3 buttons, 8x8x4 battery and 3 small breakout boards (sizes are available). I am looking for someone to design for me their enclosure.

Hi there. I wish to develop a game for Arduino ESP32. I am having a developer design the PCB. Here is a full, detailed explanation of the game. Please let me know if you have any questions regarding it, as could be a bit difficult to understand. Here is a video that shows an *old* version of the game in action, which is incomplete and a prototype, but showcases the basic features of it: This must be done perfectly! The game should not require Internet access to work, this should be OPTIONAL. So, if the establishment has WiFi then we connect the server but otherwise we turn it off. Please let me know
I need 4-20mA signal isolation circuit with minimal components and cost. 4-20mA signal coming from the sensors (transmitter) and sampling by an ESP32.
...'TWO Triggers'. Project Functionality: - Keep track of time - Show time on OLED when toggle button/switch is in on position. (Stop ATMEGA sleeping/lower power usage when toggle button is up as well). - Set Date / Time with buttons(ESC/BACK, DWN, UP, ENTER) OPTIONAL:> Set Trigger Times. -Trigger #1 is for an external relay low to high voltage (OPTOCOUPLED/ISOLATED) When this trigger is active current should always be 'on'. - Trigger #2 is to replicate a 'button press', plain signal on the GPIO output pin. When trigger #2 is 'pressed' 20seconds later Trigger 1 will close off. I have designed a basic PCB you can see from the attached picture. It has the following components - ATMEGA NANO 3.0 - DS1302 (time clock) - OLED screen 0...
...that will use the ESP32-CAM module that has SD card and PIR motion sensor. The functionality is: ESP32-CAM module in deep sleep. When PIR senses motion, the ESP-CAM must take a Video for "video_length" in seconds. The video is then written to the SD card. The video file is then uploaded to a IP address and Port on my server. The video file is then deleted from the SD card. A "" text file on the SD card MUST be used to enable the changing of certain parameters: Example: Camera001 // camera name 11 // framesize 11=hd 600 // length of video in seconds GMT // timezone Afrihost Fibre RC // ssid wifi name mrpeanut // ssid password // IP address for Post video file 17178 // Port for Post video file Above taken from: ""

First we need to validate a Strip via a RF ID or any economical method and after that ESP32 Cam module will take picture and on that picture we need to do some processing for hat we will provide logic and whatever result come out of that will store in memory for future check and that result needs to be display on LCD screen (1.44" SPI}.

I’m looking for schematics (only) for electrolysis and thermolysis driven by esp32 mcu.
Im trying to design a handheld device that would help me diagnose failed components. A quadrature encoder and a SSI linear positioning transducer. I have most of the electrical design done. I would need help with the firmware. Basically. I would like to read the signal from the encoder and The transducer and display it on a screen (preferably an oled screen). And also replicate those signals. The idea behind the device is I want to hook up on the ( encoder let’s say) spin it by hand and see if it still works ( see if all channels are working ) then if it’s working, unhook the encoder and hook on the cable and create an encoder signal to send to the PLC, to see if the wiring is good

i am looking for a an all-in-on...(currently achieved through thingtweet) to my mobile phone when thresholds are crossed. the module also has Red,Yellow,Green LED's that are activated by accelerometer, to provide visual indication of gas/threshold status. as this is a V2 prototype, i already have the schematics and coding from the first evolution. i am now looking for miniaturisation and added functionality. The first iteration used ESP32 but i have decided to switch to the teensy LC and use an HM-BT4502 BLE module (to reduce the drain on the battery). The plan was to produce a separate unit that would act as a BLE receiver and convert to WIFI (this would be plugged in nearby) if this is something you would be interested in working on, i would appreciate the opportunity to d...
...have a Raspberry Pi Modbus client (Raspberry Pi OS Lite (released on 2022-04-04)) that needs to communicate with 30 ESP32 Modbus servers over RS485/UART. On the Raspberry Pi we are using the Node.js library "modbus-serial" (with some modifications to test software flow control). We have also tested the communication with "modbus_tk" in Python and are getting the same behaviour. The current status is: - Hardware flow control does not seem to work on the Raspberry Pi. - Using a USB-UART adapter, the communication is working in both directions (only tested with a single ESP32). - Using RS485, we got the Raspberry Pi sending when controlling the RTS pin from the library. The ESP32 is responding as expected. We managed to measure a response on the R...

Hi, After a Rapberry Pi 4b Breakout Board. The board is roughly, 26x 21 cm in total size. The prupose is to have thid master board that the Raspberry PI plugs onto and then the SUB BOARD PLUG IN/SOLDER ON IT. Existing boards are such as AUDIO DAC AMPLIFIER 5V BUCK STEP DOWN 12V BUCK STEPDOWN MINI OLED SCREEN .96 Inputs for voltage and outputs for audio and a data line for ws2812. Rough layout is something like the following attached image. Regards Tristan
