I had a board in communication with a desktop PC software. Due to the obsolescence of the MCPU, we changed by another electronic board. Some commands for the new board have been already written. I am looking for somebody who can modifiy the new embedded software to work with my Desktop software. This board controls up to 3 motor drivers and 1 optical end switch on one axis and 2 endstops on the other axis.

We have a unique device sensor type application. The device consists of one large capacitive sensor array similar to a large touch screen and a small control and interface board containing an ARM M3 controller and color TFT display which both controls the sensor array and displays the results. The engineer we seek must have good knowledge of capacitive sensing including projected self and mutual capacitive sensing techniques as well as C programming skills, experience with embedded design and pcb layout. The device is also battery operated and thus contains a small buck/boost regulator and 500mA charger. We need someone with experience with microcontrollers, battery operated designs, TFT displays, capacitance sensing, pcb layout and prototyping.

Looking to create a prototype for a Bluetooth based device that can be remotely controlled from a mobile app. You'll need to have a proven experience of creating a low voltage devices, be comfortable designing circuit boards and creating a prototype. Big plus if you created a similar integration between IoT (Internet of Things) and mobile apps. You will not need to create the mobile app but you'll need to work with the rest of the team to enable the platform which the will run the firmware. Do you enjoy working with Microcontrollers such as Arduino or Raspberry Pie? Then this project might be of interest to you.

Hello, Thanks for your reading. MetaWearCPro use nRF51822 mcu. I tried to read the CHIP_ID value(0xD1) of BMI160 in MetaWearCPro firmware using SPI. But I could not get the correct value(0xD1). The read value always was 0xFF. This is my working file. https://drive.google.com/open?id=0Bx7a3vJR7vSuRFBYcWYwanFEMEU When you complete this job on MetaWearCPro, I will test and confirm your firmware on my side. I hope that you will help me correctly. If you finish this job in 2 days, I will pay bonus $25. Thank you for your time. Best, regards.
