I'm just starting with the DSP56F827EVM, and I am wondering which
development software should I start with the SDK or CodeWarrier?
My overall goal is to read from the ADC channels and store the results
on a SD card (external compactFlash) using SPI to transfer the data.
Once I have that down I would like to use JTAG to change the sampling
rate of the ADC from a laptop.
I know it a lot of work, but any help (examples and stuff)on what's
the best way to start would be appreciated.
From my experience with the 56F8346 which must not be too different in
this regard, Codewarrior with the Processor Expert "beans" would be the
fastest way to get started.
The JTAG port is used for debugging and loading program code; for
communicating with a PC to change the ADC sample rates, it would be
much easier to use a serial port so you can work with Hyperterminal or
another communication program on the PC.
Another very elegant method is to use the free PC-Master application
that comes with the Motorola Motor Control library. This also uses a
serial port, but on the PC side you can use html pages to create a
graphical user interface very easily.
For writing to the SD cards, I put together a little adapter card that
includes the SD-Card connector and a real time clock chip, which is
just about ready for going into distribution. It will include some
basic example code for writing to the card in a FAT16 file system so it
can be read on the PC directly.
