目标单片机PIC18F14K22传输机MCP2021A作为从机;MCPIC16F1718传输机MCP2021A作为主控开发工具:MPLAB X4.20/XC8 1.45/MCC 3.55.1/LIN驱动程序V2.3/库版本V1.65.2 FPIC10/12/16/18 MCU背景:几天前,我提交的题目是关于MCC Lin驱动程序的问题。RY V2.3“我使用PIC 16F1718作为主总线和从设备的LIN总线,在我得到支持之后它们工作得很好,现在我尝试使用PIC 18F14K22作为LIN总线的从属而不是PIC16F1718,我发现UART接口有问题(不能运行到接收中断服务例程)。虽然我已经在MCC和主循环中启用了中断(ununand全局和外围中断)time0中断(LIN看门狗)是可以的,但是EUART中断事件不能被捕获:PIC 18F14K22空隙中断初始化的PIC中程兼容模式(空隙){//禁用中断优先级向量(16CXXX兼容模式)RCONTITION(IPEN=0);}中断中断(中断)管理器(空隙){//中断处理程序(ItCONBITS.TMR0IE=1和&;Tim0IF=1){TMR0IISR());否则,(IncBITS.PEI= 1){if(Py1BIT.TXY==1和AMP)否则,如果(Py1BITS.RCIE=1和&;和PIP1BITS.RCIF=1){EUARARTHORXDeFultStULTHANDHANDLE();}{ / /未处理中断} { / /未处理中断} /**文件** /现在我找不到根本原因,请他LP我!提前谢谢!

Thank you in advance ! |

UART RX在PIN RB5上,这也是一个11.那个PIN已经从模拟切换到数字模式吗?
以上来自于百度翻译 以下为原文 UART RX is on pin RB5, which is also AN11. Has that pin been switched from analog to digital mode? |

非常感谢你!你是对的!MCC没有生成ANSELX的代码,虽然我已经设置AN11作为数字输入。
以上来自于百度翻译 以下为原文 Thank you very much! You are right ! The MCC did not generate the code for ANSELx,though i have set the AN11 as digital input |

这应该被报告(AH啊)到微芯片开发商,因为这是第二次在几天内出来。
以上来自于百度翻译 以下为原文 This should be reported (ah ah) to Microchip Developers, since it's the second time in a few days that comes out. |
