debug.spc

dragon ball vz328 上的一个例子程序。 用于做手持仪表用。

/******************************************************************************

	This SPC file is designed for the this sample program for both 1 bit/pixel 
	and 2 bits/pixel, and 
	This file is set with the following default value:
		RAM size = 4M byte, 
		Code Address start at 0x400000
		LCD width = 160 pixels
		LCD height = 220 pixels
    	Please adjust the above value to meet your platform. 
    
	For SingleStep Debugging System(SDS) user only:
	How to optimum malloc size after debugging stage
	1. First set the RAM size to 4M, so as the malloc size
	2. Error message will be generated after linking
	3. Then, calculate the optimum malloc size by substracting
	   exceeding bytes from the total memory size
	4. Finally write the optimum size in the malloc field
	5. This optimum need to be calculated again after modified 
	   source code.  So it is recommand to found it after debugging 
	   stage.
	6. For more detail, please refer to the Programmer's Manual Ch 34.3
