Mikrokontrollor Jobs

Hi, I have software for microcontroller PIC32MX340512H which reads data from A/D converter MCP3424 via I2C bus. The program only works properly if MCP3424 measures a negative value. In this case, PIC32MX340512H displays the correct value. If MCP3424 measures a positive value (voltage), PIC32MX340512H will show an incorrect value. For example: if I connect -1.5V voltage to MCP3424, then PIC32 wil...

I would like a field deployable data acquisition system (preferably using something simple like arduino) that will record a fluxgate magnetometer for days in the open air. If you want to look it up, this will be used for geophysics, one use will be to be a base magnetometer, which will remove for the magnetic changes due to solar storms and the second will be to record magnetotellurics, which can...

I'm working on a prototype for a project and I need to source a circular LCD/OLED (or similar) countdown display timer - see the attached rough sketch. The timer must only countdown days automatically, not hours, minutes or seconds, and be operated by a battery that you would get in a digital wristwatch or car key fob. It needs to be simple and basic in its functionality. If I want to set t...

Dear All, I am interested in a Pan/ Tilt face tracking with Arduino/ Raspberry pie/ other with python OpenCV or similar and your suggested chosen hardware: microcontroller/ high quality camera.
