Function Documentation

void handelPackegesOnBulkInEp

(

void

)

This method takes the Data out of the UART Buffer and send them to the Host(Endpoint 4)

Todo:

Find a better way of calculating absolute values

Definition at line 107 of file virtual_com_port.c.

void handelPackegesOnBulkOutEp

(

void

)

This method handles received data from the host and puts them on the UART Buffer to the MSP555 (Endpoint 8).

If the available data is to big they will be skipt. If the data coming in to fast maybe old data will be overwritten

Definition at line 148 of file virtual_com_port.c.

void handelVirtualComPortPackages

(

void

)

This method runs the package handling for the virtual com port.

It has to be called periodical in the main routine.

Definition at line 175 of file virtual_com_port.c.

void initVirtualComPort

(

void

)

This method initials the virtual com port.

It sets the RS-232 initial values , configs endpoint 1,4 and 6 and their fifos, disable the endpoints interrupts and resets the fifos.
