buffer and interrupt mechanism we established for
USART5.
A Good Day's Coding
Everything we have coded thus far can be reused by
either the PIC32MX575F512H or PIC32MX795F512L. The
download package at the article link that accompanies this
discussion contains all of the source code we produced,
plus all of the necessary code to bring up a
PIC32MX575F512H. If you wish to apply the download
package to a PIC32MX795F512L, all you have to do is
inform the XC32 C compiler that the target is a
PIC32MX795F512L instead of a PIC32MX575F512H.
The download package also contains the complete
ExpressPCB hardware and schematic file set for the
PIC32MX575F512H and PIC32MX795F512L printed
circuit boards we have designed.
We still have some coding to do. The
PIC32MX575F512H and PIC32MX795F512L drivers for
the microSD card are still to be tapped out. We also need
to feed some characters through the FTDI and ST3232
serial ports. The RTCC driver firmware is also waiting to be
completed.
So, it looks like I’ll be a busy little boy. We’ll pick up
where we left off in the next installment of the Design
Cycle. NV
