RC0和RC1脚不能正常输出
本帖最后由 pzsh 于 2022-8-15 16:52 编辑pic18f26k80写程序的时候发现,我明明把RC0和RC1定义成输出,但是调试时却不能正常驱动
是因为这两个引脚有其他特殊功能吗
配置位信息看下

T1CONbits.TMR1CS0 = 0; //clock source is the system clock (FOSC/4)
T1CONbits.T1CKPS0 = 0;
T1CONbits.T1CKPS1 = 0; //Prescale value = 001:1
T1CONbits.RD16 = 1; //16bit
T1CONbits.TMR1ON = 0; //不使能Timer1
TMR1H = TMR1_Seted_H;
TMR1L = TMR1_Seted;
原理图:
// PIC18F4580/4585/4680

配置位没配置好
#pragma config SOSCSEL = DIG // SOSC Power Selection and mode Configuration bits (Digital (SCLKI) mode)
配置位这个东西,有没有图形化配置的工具。
MCC听说可以配置字,但是没找到。
配置字不是专门一个图形界面的,一般分散在各个外设里 如果不需要图形界面,配置字是有一个专门窗口读写的 没有注意上面各楼层发帖时间的间隔以及发帖者的注册日期吗? 哦,那我就知道怎么回事了,多谢大家
没有配置好吧
