Function Documentation

static void BluetoothPowerOff ( void )

inlinestatic

Switches the Bluetooth Power off.

static void BluetoothPowerOn ( void )

inlinestatic

Switches the Bluetooth Power on.

void delay10ms ( delay_t delay10ms )

Delay for a multiple of 10ms.

This function allows delays up to the range of delay_t controlled by the timer interrupt.
delay_t should be an unsigned integer type.
delaycnt must be decremented in the 100Hz-Interrupt.
This function of course takes care of the Watchdog and puts the CPU into sleep mode until the time expires.

Parameters

delay10ms Delay in multiple of 10ms

Note: This function is not reentrant since there is only one delaycnt! The timer interrupt has to be enabled when calling this function else it will result in an infinite loop. Not even the watchdog would take you out!

static bool GetSig1 ( void )

inlinestatic

Gets State of Optocoupler 1 True means Optocoupler is ON.

static bool GetSig2 ( void )

inlinestatic

Gets State of Optocoupler 2 True means Optocoupler is ON.

static void SensorPowerOff ( void )

inlinestatic

Switches the Sensor Power off.

static void SensorPowerOn ( void )

inlinestatic

Switches the Sensor Power on.

void SetAnalogPerCent ( double perCent )

Sets the analog Instrument display.

Parameters

perCent The value in a range from 0.0 to 100.0. Exceeding values will be trimmed correctly.

static void Sig1OFF ( void )

inlinestatic

Switches Signal Output Optocoupler 1 to OFF.

static void Sig1ON ( void )

inlinestatic

Switches Signal Output Optocoupler 1 to ON.

static void Sig2OFF ( void )

inlinestatic

Switches Signal Output Optocoupler 2 to OFF.

static void Sig2ON ( void )

inlinestatic

Switches Signal Output Optocoupler 2 to ON.
