Compiling and Running the Demo(s)
The main file that we introduce to access the FLASH API is CHAM_PIC_FLASH_DRV_V010.C|H. Once you compile and
FLASH the Chameleon with the demo, it displays a menu on both the NTSC and VGA displays, this is shown in Figure
31.6 below.
Figure 31.6 – The FLASH demo main menu.
Referring to Figure 31.6 , there are two menu options:
1. Xmodem receive to FLASH.
2. Dump FLASH to screen.
You control the menu with the local keyboard plugged into the Chameleon’s PS/2 port.
Option 1, starts a 3 second countdown and then starts the X-Modem download. Thus, the PC side better already have
the XModem file transfer program ready and waiting. Moreover, the programs dumps the data to the screen in ASCII
format, so I suggest that what your transfer its human readable. Also, make it short, maybe a few hundred bytes to a
couple K. The AVR only has enough room for a 1K receive buffer (the PIC obviously has more room than the AVR but we
