# BP6A AFE API
This project helps users easily use AFE in BP6A.
You can find API documents in ./doc/html/index.html

## BP6A ECG API
This section is about how to use ECG APIs. Please following steps to get ECG data
- step 1. call ecg_init to enable ecg function
- step 2. call ecg_set_decimation_rate to set sampling rate
- step 3. call ecg_set_callback to get notification when ECG data ready
- step 4. call ecg_start to start ECG data streaming
- step 5. The callback function will be called when the ECG data ready.
