EXTSRAM.C
This program first maps the external SRAM to the I/O Bank 0 register with a maximum
of 15 wait states, chip select strobe (which is ignored because of the circuitry), and
allows writes. The first 256 bytes of SRAM are cleared and read back. Values are then
written to the same area and are read back. The Dynamic C
cate if writes and reads did not occur
Connect an external SRAM as shown below before you run this sample program.
FLASHLED.C
LED DS3 is controlled by Parallel Port A bit 1 (PA1).
FLASHLED2.C
LED DS3 is controlled by Parallel Port A bit 1 (PA1).
This sample program also shows the use of the
Dynamic C to update watch expressions while running. The following steps explain
how to do this.
1. Add a watch expression for "k" in the Inspect > Add Watch dialog box.
2. Click "Add" or "Add to top" so that it will be in the watch list permanently.
3. Click OK to close the dialog box.
4. Press <Ctrl+U> while the program is running. This will update the watch window
