本帖最后由fw19876311于2025-1-1417:01编辑STM32F103C8T6正常运行的代码，直接平替GD32F103C8，CAN部分初始化异常，一直返回失败uint8_tCAN_Init(CAN_TypeDef*CANx,CAN_InitTypeDef*CAN_InitStruct){uint8_tInitStatus=CAN_InitStatus_Failed;uint32_twait_ack=0x00000000;/*Checktheparameters*/assert_param(IS_CAN_ALL_PERIPH(CANx));assert_param(IS_FUNCTIONAL_STATE(CAN_InitStruct->CAN_TTCM));assert_param(IS_FUNCTIONAL_STATE(CAN_InitStruct->CAN_ABOM));assert_param(IS_FUNCTIONAL_STATE(CAN_InitStruct->CAN_AWUM));assert_param(IS_FUNCTIONAL_STATE(CAN_InitStruct->CAN_NART));assert_param(IS_FUNCTIONAL_STATE(CAN_InitStruct->CAN_RFLM));assert_param(IS_FUNCTIONAL_STATE(CAN_InitStruct->CAN_TXFP));assert_param(IS_CAN_MODE(CAN_InitStruct->CAN_Mode));assert_param(IS_CAN_SJW(CAN_InitStruct->CAN_SJW));assert_param(IS_CAN_BS1(CAN_InitStruct->CAN_BS1));assert_param(IS_CAN_BS2(CAN_InitStruct->CAN_BS2));assert_param(IS_CAN_PRESCALER(CAN_InitStruct->CAN_Prescaler));/*Exitfromsleepmode*/CANx->MCR&=(~(uint32_t)CAN_MCR_SLEEP);/*Requestinitialisation*/CANx->MCR|=CAN_MCR_INRQ;/*Waittheacknowledge*/while(((CANx->MSR&CAN_MSR_INAK)!=CAN_MSR_INAK)&&(wait_ack!=INAK_TIMEOUT)){wait_ack++;}/*Checkacknowledge*/if((CANx->MSR&CAN_MSR_INAK)!=CAN_MSR_INAK){InitStatus=CAN_InitStatus_Failed;=====================卡在这个位置}请教各位，有遇到过吗？麻烦指导下，谢谢大家！

开机后oled上ADC电压值有变化，旋转编码器后，oled就显示一个值没有变化#include#include"N76E003.h"#include"Common.h"#include"Delay.h"#include"SFR_Macro.h"#include"Function_Define.h"#include"oled.h"#include"bmp.h"UINT8temp=0xD7;UINT8temp1=0x02;voidADC_ISR(void)interrupt11{if(ADCF){clr_ADCF;set_ADCS;//printf("\nValue=0x%bx",ADCRH);}}voidshow(){uint16_tBandGap_H,BandGap_L,BandGap_v;uint16_tvoltage=0;charaa[10];floatv;BandGap_H=ADCRH;BandGap_L=ADCRL;BandGap_v=BandGap_H

如题，请问有FAE指导一下吗？
