Detailed Description

Example class decoding instructions sent to a NMC9314 EEPROM memory (Microwire interface)

Constructor & Destructor Documentation

microwire::microwire	(	uint8_t	pins[] = NULL,
		uint8_t	npin = 4
	)

Constructor.

call init_acquisition()

Member Function Documentation

void microwire::decode ( void  )

virtual

Perform all the decoding.

This function decodes:

• activity from CS pin,
• transitions from CLK,
• binary from MOSI and MISO
• messages from MOSI binary,
• messages from MISO binary

Implements protocol.

void microwire::decode_miso

(

)

function extracting messages from MISO

Puts the extracted messages array in miso_mess, from binary miso and activity cs.

void microwire::decode_mosi

(

)

function extracting messages from MOSI

Puts the extracted messages array in mosi_mess, from binary mosi and activity cs.

int microwire::Draw ( mglGraph *  gr )

virtual

Draw all messages.

Parameters

gr	pointer to mglGraph object

Implements protocol.

Member Data Documentation

transition microwire::clk

Contain the clock transitions.

Determined from CLK pin

activity microwire::cs

Contain the activity.

Determined from CS pin

binary microwire::miso

Contain the MISO binary data.

Determined from MISO pin rawdata, clock transitions and activity

message* microwire::miso_mess

array of message decoded from miso

See Also

decode_miso()

binary microwire::mosi

Contain the MOSI binary data.

Determined from MOSI pin rawdata, clock transitions and activity

message* microwire::mosi_mess

array of message decoded from mosi
