Microcontorller (STM32L) interfacing with pervasive eink display (Re posted)

hi, I am working on a project for my design course and I need some help regrading the firmware and software part. Eventually I am trying to make eink display to mirror an ipad screen, but for the this project, I want to connect a Bluetooth (preferably a low energy BLE) dongle to my laptop and send a picture (.EPD picture since eink TCM accepts .EPD format) from my laptop to a low energy STM32L microcontoller (through Bluetooth), and then to the eink display's TCM module, so the picture that is sent from laptop is shown on the eink screen. Here is the eink kit that i have bought: [login to view URL] I have attached the developer guide of this product. I have been working on the project. However I am struggling to get SPI work/communicate with TCM module, and I am thinking to outsource microcontroller side of programming. I mean how microcontroller is integrated with the Eink and how communication is done between these devices and Bluetooth encoding/decoding part. These will help me to get the ball rolling. I am hopeful that I can do the ipad side of project by myself. My expectations: 1. Support Major Commands as in the E-ink Datasheet only (each command is wrapped via a single function API) 2. Communication Commands to support for TCM: #ResetDataPointer #Upload Image Data #DisplayUpdate #GetDeviceInfo #GetDeviceId #GetSystemInfo #GetSystemVersionCode #ReadSensorData And for the Bluetooth part, basic byte by byte transmission and receiving. #sentByte() #ReciveByte() At the end I want to scale this project so it can work with ipad (ios device) I will try to write an app that get a screenshot of ipad's screen and transmit it through the Bluetooth low energy (BLE 4) to the STM32 side. Therefore the code should be scalable to this main objective. Please tell me how long it would take you to finish this project ( I am really in hurry). And how much it will cost. My budget is a little bit tight so please give me your best price. thanks PS. I have a open mind to any suggestion regarding microcontoller. STM32 or Mbed or anything that is suitable for this project (low power consumption is kinda important for me). Also last time I was looking to develop for Bluetooth low energy, however I am again open minded for other ways of wireless communications as well. I am attaching a general of block diagram to explain what I have in mind.
