Paid on delivery

Small project to code and configure a project for the Atmel ATSAM4S microcontroller. There are 3 requirements for this project: 1) Implement a USB stack capable of vendor requests and bulk-endpoints for full-speed. 2) Implement and configure DMA to access the SPI controller. 3) Implement a bootloader so that the device's firmware can be upgraded over USB. For testing, I will access the device using Libusb, to be able to send commands, read/write to the SPI controller (using DMA for performance), and finally implement a firmware update over USB. For final testing, a sample ATSAM4S demo board will be provided.
