shervinemami 1:2749e6ff50ce 2 * Handheld BLE finger input device based on Seeed Studio Tiny BLE (TinyBLE).
shervinemami 1:2749e6ff50ce 3 * By Shervin Emami (http://shervinemami.info/), 25th Aug 2018.
shervinemami 1:2749e6ff50ce 4 * If the analog voltage on a "finger" pin is below a threshold voltage,
shervinemami 1:2749e6ff50ce 5 * then it sends a mouse command using Bluetooth BLE, so that any computer or
shervinemami 1:2749e6ff50ce 6 * smartphone can be configured to perform a desired function due to this input event.
shervinemami 1:2749e6ff50ce 7 *
shervinemami 1:2749e6ff50ce 8 *
shervinemami 1:2749e6ff50ce 9 * This program implements a complete HID-over-Gatt Profile:
shervinemami 1:2749e6ff50ce 10 * - HID is provided by KeyboardService
shervinemami 1:2749e6ff50ce 11 * - Battery Service
shervinemami 1:2749e6ff50ce 12 * - Device Information Service
shervinemami 1:2749e6ff50ce 13 *
shervinemami 1:2749e6ff50ce 14 * Complete strings can be sent over BLE using printf. Please note, however, than a 12char string
shervinemami 1:2749e6ff50ce 15 * will take about 500ms to transmit, principally because of the limited notification rate in BLE.
shervinemami 1:2749e6ff50ce 16 * KeyboardService uses a circular buffer to store the strings to send, and calls to putc will fail
shervinemami 1:2749e6ff50ce 17 * once this buffer is full. This will result in partial strings being sent to the client.
shervinemami 1:2749e6ff50ce 18
shervinemami 1:2749e6ff50ce 19 * Tested with mbed libraries for April 2nd, 2018. If you use a newer version of mbed or other
shervinemami 1:2749e6ff50ce 20 * libs and you have problems, try rolling back to April 2nd, 2018.
