Electrocardiogram (
Ecg
) Signals
The Electrocardiogram (
Ecg
)
•
Ecg
: electrical manifestation of heart activity recorded
from the body surface
•
monitoring of heart rate
The
Ecg
signal can be recorded fairly easily with surface

2.5.5 BFH Mother Board
On the mother board the Olimex STM32H103 board is mounted on. The mother board has a
power supply and drivers for interfaces.
•
The mother board uses the power supply form the STM32H103 board. Just connect the
STM32H103 with USB and the mother board is powered.
•
4 LEDs, lighting when tied to LOW (D1, connected with J24; D2-J25; D3-J28; D4-J28)
•
2 Buttons with a pull-up resistor, pressed gives a LOW state (S1, connected with J2; S2-J12)
•
1 Serial driver (RS232) (Rx-PA3; Tx-PA2; RTS-PA1; CTS-PA0 if DIPs are set according to
Figure
•
2 potentiometer for analog inputs (R8-PC0; R9-PC1 when J26 and J27 are set)
