Function Documentation

FilterSample()

float32_t FilterSample	(	float32_t	inData,
		unsigned char	filterIndex
	)

It calls the routines for filtering a new sample.

Parameters

[in]	inData	float input value
[in]	filterIndex	index of the channel which the sample belongs

Returns

float output value.

This function contains the routines needed to apply digital filters to the data in a on-fly technique. This means that the latest acquired sample is passed through the filters and the filtered version is returned by this function.

Measured Execution Time @80MHz: 13/07/2016 -> 3 us

ResetFilterArrays()

void ResetFilterArrays

(

unsigned char

nCh

)

Needed to reset the history of the filters and delete the previous states.

Parameters

[in]

nCh

number of channels

Returns

none.

Measured Execution Time @80MHz: 13/07/2016 -> 16 us

UARTReceive4Bytes()

void UARTReceive4Bytes

(

uint32_t *

ptr

)

This function can be used to easily handle the reception on the UART of 4bytes sized variables, e. g. float.

Parameters

[in]

*ptr

points the variable to receive

Returns

none.

UARTSend4Bytes()

void UARTSend4Bytes

(

unsigned char *

ptr

)

This function can be used to easily handle the transmit on the UART of 4bytes sized variables, e. g. float.

Parameters

[in]

*ptr

points the variable to send

Returns

none.

UARTSendByte()

void UARTSendByte

(

unsigned char

byte

)

This function can be used to easily handle the transmission on the UART of one byte. It is meant for the application of flow control.

Parameters

[in]

byte

to send

Returns

none.
