Hi, I need lp55231 or lp55xxx series led driver's source and header files.(.c and .h file) Datasheet:- Note:- Arduino Lib is not needed. Required:- 1) API's for Engine run(define, write a value, and run the engine.) 2)Controller for STM32/CC1352/CC1310.
Need assistance developing a prototype using a development board where we need to interface some displays and sensors, receive bluetooth commands and make it programmable over usb. must be aware of I2c and SPI interfacing protocols and have experience developing firmware
The current OTG provides option of setting temperature using and allows to set temperature and modes using a dial. The basic idea is to tinker around with it and plug in our own custom-built circuit and a few more components. The idea is to run this OTG at a predictable & reliable temperature/time and control via-mobile using bluetooth connectivity. Steps involved: 1. Rip open existing OTG and understand the system. 2. Insert an NTC sensor at an appropriate place to get the temperature 3. Heaters must be connected via SSR so as to be able to control power precisely 4. Use input via mobile using a bluetooth terminal (available on google play) that sends temperature setting and time. The input will be read in by the circuit and executed. 5. The circuit reads in the temperature and ti...
I have made a arduino uno windows login project via rfid, need some helps with modifying it with these things: 1) Able to store multiple login information 2) Passwords stored encrypted 3) Add and modify data without using arduino IDE. 4) limit number of tries
We have a elivetor project For using automatic we'll try to using Arduino based automation I want just a program To control a lift on 4 floors If i give a input as a lift calling from a push boton Lift will be stop on that floor Like i am pushed 2nd boton lift will moving 1st flore to second floor and stop with proxy sensor Than i am pushed 3rd boton lift will moving 2nd floor to 3rd floor As usual lift moving 3rd to 4th floor And any tine lift gose on any floor to calling which floor required I want just a program for Arduino uno And it's pin discretion also Which pin has which action perform
This project need someone who know VB, COM port and Python You can read more detail in attachment file. thank you!
Greetings We are looking for an IOT LPWA expert that can consult us on ongoing basis. We are developing a hardware for GPS and satelite tracking using LTE-M targeting operators. You should have extensive experience working in the LPWA field and understand firmware and embeded systems for LPWA . More information will be provided to the ideal candidates.
I am looking for a standalone GPS time sync portable device with a display and can show UTC/Local Time and with different time zones also day, date, speed, heading, SNR, altitude and latitude/longitude, sunrise/sunset and how many satellites in view and strength and fix also compass, bearing, temperature, barometer.
I have Baldor Inverter need parameters setting. Which is just simple like STOP, START, POT, FWD, REV and E-STOP setting on the inverter.
Need Ardupilot / Raspberry Pi Expert to connect GPS to our rover More details will be shared on chat. Project Deadline 1 day
The task is to design an RF energy harvester circuit for dual-band frequencies from GSM/900 MHz and GSM/18000 MHz using Keysight ADS software. It requires transmission line impedance matching and a rectifier circuit. The circuit will be fabricated later so layout design is also required. Please see the attached pdf for details.

Using Pynq Z2 FPGA to connect a camera (OV7670 - CMOS Sensor), and then display the video on a monitor through HDMI output. The Project is built using VHDL language and IP blocks. The purpose of this it's to build also nurual network to recognize a face/person so the camera can follow the object using servo motor.
Hi there, This project is about the automation of my hydroponic farm, I Have attached a block diagram about what things have to be automated, such as a timer-based relay to control the on/off function, and the day-night cycle of EC/Ph management of Nutrient solution based on a feedback loop, Temp and humidity control of the entire system. We can discuss further details over a call or meet.
I am looking for an expert in Arduino board with assembly language using Arduino mega 2560
I am looking for RC5 Protocol decode in PSOC 4 cypress microcontroller. Kindly find attached logic analyser data whatever I received in analyser similarly I want to receive in psoc4. also find attached schematic of Cypress microcontroller also find attached reference code using this code I did not receive output as expectation.
I am looking for part time or full time embedded developer who can work atleast 2-3 hours on daily basis and work on support and development of embedded systems. Ideal candidate must have both hardware and firmware experience. The platform will be aurdino, esp, pic, stm, ble,uwb and like to work for long term basis. My budgets are limited and will give some other incentive based on product success.
Project firmware alterations below // we will provide full source code 1. ensure boot0 is emmc on our img file 2. secondary bootloader boot0 should be eMMC varient which loads uboot from eMMC 3. importantly the steps to pull in the locally compiled boot0_emmc varient into final image 4. ensure coding is compatible with imx series cameras 5. create firstly image file running uart0 =================== adding on: 6. create 2nd image file running uart3 with src configs 7. Uboot src include/configs/sun8iw17p1.h line 284 you can change kernel boot params for default console Change console=ttyUSB3 and try if console appears in USB 8. u-boot we can but sure need inputs for uart3 changes, compile and boot0 image emmc variant ===================

I want the software for an object tracking robot,which can automatically detect insects and rats and aim and shoot a laser controlled by a servo,i am using an Arduino mega,huskylens,dc geared motors for x,y axis rotation.i am mounting this on an extra information message me.
I am using an Arduino mega,Using husky lens which should auto matically detect insect,track it and shoot a laser wich is controlled by a servo motor,i am using dc geared motors for x,y axis rotation.I am mounting this on a autonomous i only need the coding part for the insect tracking and shooting a laser controlled by a servo.
Hello everybody, i am trying to make a Wireguard VPN router. i tried to install on my ESP32, NAT Router but unfortunately a Wireguard VPN cannot be configured. I would like someone to help me modify this source code to add a Wireguard Client connection as well. or if there is something simpler that you have already developed I would be very happy.
Hi, After a PCB design and possible coding for a WS2812B clock. Similar to attached image. Basic Functions - WS2812B leds around clock, 60 for inner circle, 12 for outer circle. - Text on front of clock for the 'hr'. - Buttons on back for reset wifi / set time. - Button battery for holding the time when no power. - Light sensor to 'dim down light at night', and make brighter during the day. Advanced Functions. - Integrated Camera module at centre of clock. Code Integrations - ESP32 WiFiManager (code exists) - ES32 CAM remote viewer (code exists) - Web Based page for modification of lighting. -- Adjust dimming (light sensor) -- WS2812 colour picker wheel for setting, hour, minute, seconds. Thanks Tristan
* This project is built with Micropython on ESP32-PICO-V3-02(compatible with normal ESP32) * It requires to read a value from a pressure sensor (I2C connection) * Tricky is that need to run on ESP32 UltraLowPower processor while the MCU is in sleep mode. IMPORTANT! Please see attached PDF files, I explained the whole requirements and suggestions. Please NOTIFY ME! what MCU and I2C sensor will you use for this project.
