Microcontroller Jobs
Generate new code for an ARM series MCU (likely the ATSAME70J19B). Two processors on two separate PCBs will monitor GPIO pins for digital and analog inputs and comparing those values to alarm set points and annunciating alarm status via LED outputs (about 20; green=good, red=alarm). The two micros will communicate between each other via serial ports (converted to RS485 via single chip convertor). A couple other features such as detecting physical key turn-on and time-out-timers will be required. PCBs are being laid out now. Coding should start right away. Will include Ethernet port and Simple GUI for viewing/clearing alarms.
This is a fairly major revision of the mixer/intercom updating out of date components, Improving speaker amplification, reducing background noise on intercom mics and adding USB interface to the unit. Existing product is here:
Requiring a quote/pricing for a project that involves ADS1299, Micro SD Slot, ESP32-WROOM-32D, USB and some programmable LED al being on one board and controlled by the STM32 controller. Your task would be to make all components to communicate with the STM32 and to be able to extract data from the ADS1299 using USB to PC, Bluetooth to PC and Android device . For PC and Android device to have an App that will represent graphical the extracted data from ADS1299. Pricing can be negotiated.
We are looking automatic wire cutting and stripping machine which can do this job from 0.1 mm wire ( copper wire) upto 6 mm sq and of different lengths. The machine should not use any hydraulic and pneumatic system for Operation. We would be able to give input to the machine through the push button available and also directly through the computer or data stick in case of bulk requirement ( different cable length). If the machine can itself take different cable ( sq mm) and cut it into desired length as per table or input provided in bulk would be great.

This project is to adapt an MPLAB project from a PIC32MX795F512 to a PIC32MX675F512. The previous project was completed on the Microchip Ethernet Starter Kit II and is an Ethernet 2 Serial project. There has been a new pcb built with the 675 but with many of the same components as found on the Starter Kit. The new board has some pin changes from the Starter Kit. As much as possible has been kept the same. The new board does have more capabilities than the old Starter Kit. The new capabilities will need to be implemented as a separate project after the basics have been achieved with this project. A document outlining my general communications policy and another document showing the pin changes will be included in this project. Please communicate any difficulties you may have wit...
Hi, Looking for writers, who must have worked on these board: Raspberry Pi, STM32, Arduino, PIC etc. Its a long term job so looking for low rates. Mention your technical background in the bid or recent projects. Thanks.

Design 4xSDI seamless switcher with 2 HDMI outputs which support 1080p (Full HD) In this project must use FPGA for SDI inputs with input auto-detect resolutions feature. Output interfaces (2xHDMI) must support full range resolutions up to 1080p. Each output must could configured separately (out 1 has just 1 mode and out 2 supports 2 modes) Each output could have own mode and resolutions, must not effect one out config to another output. Freelancer who want to doing this project must design hardware and software (FPGA Firmware) and send to us the sample hardware designed also at the end must deliver all source codes and source files like PCB layout and programming codes also must will describe all codes and designing to our engineers for programming new boards. All hardware costs (PCB + mat...

This report introduces the wireless sensor interface project of the SEP group project. The objective of the project is to develop a system to collect data from sensors, and to transmit this data wirelessly to a node which passes the data to a PC. Wireless transmission methods have been investigated, and it was decided that a proprietary protocol would be designed. A TDMA based protocol has been designed. Sensor tests have been performed, and the protocol has been designed and detailed in this report. This report also discusses the progress made to date on the project, and proposes a timeline for the completion of the projects
Main idea. To have multiple buttons around a office/home and when someone presses it a blink/signal will occur on the units like a common signal for an event. To ACK the signal everyone will need to press the button to confirm. This is a MVP concept design and I will add more functionality later. The only HMI will be a button and a LED (maybe RGB) so all info will be via that interface I will do all HW myself and want a fully functional software delivered. Assume the freelancer have this stuff at home to laborate and test the HW setup for a secure and proper debugging.
Hi, i need a same day turnaround for a program for a linear actuator contoller using esp32-wroom32D. I have a custom pcb with the esp, relays, power, eol sensors and led/sounder output, and would like it coding so that a bluetooth remote (used for a phone camera shutter) can trigger the actuator to extend or retract. I have been let down by my engineer and need to get this running today. Thanks!

We are an IoT company and are seeking to contract with a wonderful software developer for our technology. The following is a description of the project. Electronic modular 32x128 LED sign driven by ESP32 microcontroller with codebase written in C / C++ needs functionality added to allow loading fonts from flash, switching fonts, and designing fonts using a PHP interface. You will be working with the original developer who has 25+ years of experience and can suggest approaches. Must be familiar with C, C++, PHP, and the use of git. Previous microcontroller experience a plus. Looking forward to hearing from you!
Complete code with simulation of drone in any online platform. Quadcopter at simplest with all control simulation.
first the ultrasonic will detect the water level, if satisfied then start an internal timer and turn on the second relay for 5 minutes. Next, the proximity sensor will detect the distance of the fluid and control the third relay. Lastly, a tds sensor will tell whether to open the fourth relay or open the first relay whereby activate the ultrasonic sensor again

I am looking for an AVR/ESP programmer who will help on the code to generate an 8 pulses signal at various frequencies and various duty cycles using ESP 32 and ATMEGA328P based arduino NANO. The frequency varies from 200Khz to 1Mhz. (There is a table for the various signal pulses on the PDF files). The 8 pulses are to drive a PNP transistor! An image of a pulse we are looking to achieve. The signal in Yellow is the result we are looking for. I have other tasks as well!! Can you do it?
Hi there, We manufacture a product that uses a PIC32 as its main processor. We have connected a USB socket to the correct dedicated pins on the PIC32 (D- P56 & D+ P57) and wish to be able to have end users update the program inside the PIC32 using either a USB stick OR using a cable connected to a PC running a small uploading program. (Our testing proves a PC connects to the PI32 when the USB is plugged into this socket - the usual Microsoft chime alerts us to the connection). Will discuss more with good developers. Thanks

For developing a "Solar Inverter" using ST Arm Processor with good quality and reasonable rate which support WiFi through App Communication
1. This is a project based on a circuit board. I will provide the schematic diagram later. In the picture you see a BLE module, but I will try to add one more. 2. The connector on the upper left has 4 input, 12v, gnd, CAN+ and CAN- 3. The 4 connectors on the bottom is pretty much the same, it control 4 identical components. Each connector has 6 wires: Gnd, two output for dc motor, ws2812 data, 5v, and a switch trigger. 4. Whenever a switch is pulled to ground, it will trigger the motor to pull for 1 second. 5. Whenever a motor is pulled, the ws2812 will start to light up. 6. After 20 seconds, the motor should reverse back. And the Ws2812 strip should light off. 7. Whenever a certain CAN signal is received (will be provided), all the 4 motor should pull for a second. All 4 ws282 strip will...
