EXAMPLE 2-10:
The reader is encouraged to review the data sheet for the PIC18F14K50 EUSART
section for more information on the specifics of the configuration code.
Next, the application specific code will be added that will implement the flowchart
shown in Figure 2-6.
10. Scroll down to the ProcessIO()and copy and paste the contents of
As per the flowchart in Figure 2-6, this code will ensure that the buffer containing the
data transmitted from the RS-232 has been sent to the USB firmware. If so, the code
then checks for any new RS-232 data that has been stored in the buffer.
Example 2-11 into the section labeled:
/*****************************************************
ADD CODE TO CHECK IF RS232 HAS
BEEN SENT ALONG USB
AND THE CODE TO CHECK IF
ANY NEW RS232 TRANSMISSION
HAS BEEN RECEIVED AND STORED
