关于atmel studio的问题

2921

问答对人有帮助，内容完整，我也想知道答案 0 用了iccavr 和 atmel studio 写了同样的代码编译.. // 595 operation #define PORT_595_CLK PORTB #define PORT_595_DAT PORTA #define DAT_595 0 #define SHCLK 0 #define STCLK 1 #define CLR_595_ST() PORT_595_CLK &= ~(1< #define SET_595_ST() PORT_595_CLK \|= (1< #define CLR_595_DAT() PORT_595_DAT &= ~(1< #define SET_595_DAT() PORT_595_DAT \|= (1< #define CLR_595_SH() PORT_595_CLK &= ~(1< #define SET_595_SH() PORT_595_CLK \|= (1< #define SEND_TO_595(word) do { CLR_595_ST(); for(char i=0 ; i<8 ; i++) { CLR_595_SH(); if ((word) & (1<<(7-i))) { SET_595_DAT(); } else { CLR_595_DAT(); } SET_595_SH(); } SET_595_ST(); } while (0) //segment LED operation #define SEGLED_CLR() PORTD \|= 0xf0 #define SEGLED_SET(i) PORTD &= ~(1<<(7-i)) #define SEGLED_CODE(word) SEND_TO_595(word) //display data unsigned char led_code[] = {0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f,0x77,0x7c,0x39,0x5e,0x79,0x71} ; unsigned char dis_buff[] = {0,0,0,0}; unsigned char clock[] = {0,0}; ISR(TIMER0_COMP_vect) { static unsigned char disIndex = 0; unsigned char dis_data; dis_data = led_code[dis_buff[disIndex]]; SEGLED_CLR(); SEGLED_CODE(dis_data); SEGLED_SET(disIndex); ++disIndex; if (disIndex >4) { disIndex = 0; } } 在iccavr上面只是把那个ISR改了.. 结果iccavr是对的.. as确实错的.. iccavr 附图是as编译结果的运行.. iccavr是实现动态扫描二楼附上as编译出来的汇编 0 QQ截图20130408212103.png (33.13 KB, 下载次数: 5)
