4.17 Universal Serial Bus (USB)

2 Electrocardiogram (Ecg) Signals
The STM32F103RB embeds a full speed USB (12 Mbs) device peripheral compatible with the USB.
It has software configurable endpoint setting and suspend/resume support. The dedicated 48
MHz clock source is generated from the internal main PLL.
The CAN and USB share same pins PA11/EXT1-1 and PA12/EXT1-3, so you can't use both CAN
The Electrocardiogram (Ecg)
and USB on same time with the standard pin mapping.
• Ecg: electrical manifestation of heart activity recorded
The implementation of the USB framework would go beyond the scope of this work and is there-
fore not covered.
from the body surface
• monitoring of heart rate
The Ecg signal can be recorded fairly easily with surface
electrodes placed on the limbs and/or the chest, see pages
below.
