Nordic nRF51822 PCA10001 Support for Pervasive Display Extension Board and 1.44" ePaper Display
I just published the "ble_app_epd" project on github. This project uses the Nordic nRF51822 Evaluation Kit board to provide remote control to a Pervasive Displays 1.44" e-Paper display.
Nordic's nRF41822 Evaluation Kit contains the PCA10001 board which has the nRF51822 SoC and support circuitry useful for prototyping.
Below is a photo of the setup, showing the cabling between the two boards.
Details can be found at the github project.
The basic system is built upon and extends the Nordic nRF51 SDK example code for a virtual UART device over Bluetooth Low-Energy (BLE): the extension being support for the e-Paper display.
A phone or tablet with the Nordic-supplied nRF-UART app installed (Android version or iOS version) is used to communicate with the ble_app_epd firmware running on the PCA10001 device.
Basically this virtual UART provides a simple terminal emulation onto the PCA10001.
From this terminal emulation, the user can type the "show" or "clear" commands to invoke the e-Paper actions.
This project is a relatively simple "starter" application for Pervasive Display e-Paper support on the nRF51822 SOC. But is should provide the basic support needed for more ambitious e-Paper projects.
NOTE: This nRF51822 Evaluation Kit is being phased-out, but the new Eval Kit should work as well. At this time, the original kits are still available in many of the standard supply chains.
