2.10 Thermistor bridge - Temperature control
A thermistor bridge (with a negative coefficient) is connected to the ST6265 I/O pin PA5, which
is defined as an analog to digital converter (ADC) input. The voltage value at the ADC input
decreases when the temperature is increased. Demonstration 4 shows how the thermistor is
used to indicate temperature levels on the five LEDs (see “Running the Demos” on page 20.)
The thermistor bridge can be disconnected from the pin PA5 by removing the W24-PA5 jump-
er.
2.11 RS-232 Interface
The RS-232 interface enables you to communicate with the pre-programmed ST6265 micro-
controller provided with the Starter Kit. It includes an RS-232 buffer circuit that is connected to
a standard PC-compatible RS-232 SUBD-9 connector.
The following table lists the RS-232/ST6 pin connections:
You can disconnect these by removing the corresponding jumpers from W17 to W21.
