Analog input
One BNC connector, CN7, is connected to PA4 of the STM32F100VBT6 microcontroller as
an external analog input. or DAC output. The 50Ω terminal resistor can be enabled by
closing solder bridge SB1. A low pass filter can be implemented for the BNC connector by
replacing R44 and C33 for ADC input, or replacing R43 and C33 for DAC output with the
correct value of resistor and capacitor as requested by the end user's application.
There are also 3 analog signals available on the board:
1.
2.
3.
IrDA
IrDA communication is supported by the IrDA transceiver U14, which is connected to
USART3 of the STM32F100VBT6 microcontroller. It is enabled or disabled by jumper JP11.
Table 7.
Display and input devices
The 240x320 TFT color LCD (mounted on connector CN14) and 4 general purpose LEDs
(LD1, 2, 3, 4) are available as display devices.
A 4-direction joystick with selection key, general purpose push button (B4), wakeup button
(B2) and tamper detection button (B3) are available as input devices.

10 KΩ potentiometer RV2 connected to PC4.
IDD measurement output signal connected to PC5 for MCU power consumption test.
External ADC input which can be connected to TP3 (AIN+) and TP2 (AIN-), R45 should
be removed to avoid noise.
