嗨,我已经编写了代码来从睡眠中唤醒PIC18LF26K80,并解码UART十六进制字节7E。在模拟器中,当使用UPDM2作为调试器时,这不是成功的。7E字节是通过USB端口用FTDI电缆USB发送到UART的。我已经探查PICAND的RX PIN RB4,它确实是PIC接收的7E,但是在ICD3调试模式下,如果正确接收H’7E’字节,则UART RX例程接收HFF',然后打开UPM2的LeD0。我已经附加了5 .ASM文件,并且我在这里显示.Inc文件。检查一下我的代码,我会很感激。我忘记给.SCL文件做模拟了。它遵循

I have written code to wake up PIC18LF26K80 from sleep and decode the uart hex byte 7E. In simulator this succeds but not while using the UPM2 with ICD3 as a debugger. The 7E byte is send via the u*** port with a FTDI cable u*** to uart. I have probed the RX pin RB4 of PIC and it is indeed 7E what the PIC receives but while in ICD3 debug mode the uart rx routine receives a H'FF' If the H'7E' byte is received correctly then then LED0 of UPM2 is turned on. I have attached the 5 .asm files and I am displaying the .inc files here. If you can check my code i would be grateful. ; ###################################################################### ; Start of file "Define_IO.inc" ; ###################################################################### ;PROJECT - Wireless Camera VerA ; SECTION - PCIP PIC Code ; MODULE ; ---------------------------------------------------------------------- ; (c)2016 ; 3 Tirynthos ; Peristeri ; Athens ; 12135 ; Greece ; Tel.

我已经对我的代码做了一些修改,来处理RB0的It0:在WielySkyCasaVel.asmio.ASM中。
以上来自于百度翻译 以下为原文 I have made some changes to my code to work with the INT0 of RB0: in wireless_camera_vera.asm Loop1 NOP ; Put the device to sleep BCF OSCCON,IDLEN NOP SLEEP ;Device goes normally to sleep and it is waken by the UART byte '7E' NOP NOP ;BSF PORTA,1 ; RA1 connected to LED0 of UPM2 succeeds when wake from sleep NOP NOP NOP BTFSC PORTB,0 ;;;Here it fails!!!!! INT0 in RB0 on falling edge. It should be checking for the start bit GOTO Loop1 NOP ; Wake up from sleep due to RB4 IOC ; A high to low transition is the start bit of uart rx byte ;MOVLB 15 ;MOVLW B'00000000' ;Disable any further IOCB on pin RB4 ;MOVWF IOCB ;MOVLB 0 BSF PORTA,1 ;Never reached this point HIGH_ISR: ; Insert High Priority ISR Here ;MOVLB 15 ;MOVF PORTB,W NOP BCF INTCON,INT0IF ;MOVLB 0 retfie FAST IO.asm MOVLW B'00010001' MOVWF LATB MOVLW B'11111011' MOVWF TRISB MOVLW B'11010000' MOVWF INTCON |
