Startting a new project for a vending machine...
i am looking for a consultant to document / architect the required hardware and also develop documents explaining how the firmware should operate for a Vending Machine Controller PCB.
Project requires an RTOS expert familar with either FreeRTOS or MQX for Kenetis K40/60.

One USB HID capability to allow technician to extract daily reports from the micro.
Ability to store statistics
One door switch to determine if door is open or closed.
All necessary hardware will be shipped to the successful candidate for future firmware development.
This project is just to documented how RTOS firmware should be developed:
It must outline the RTOS tasks to be used along with semaphores, timers, mutexes, etc.
I will supply the technical documents for all hardware needed if i choose you to develop the firmware.
