GD32H757VGT6的硬件I2C读写都一直卡在while (!i2c_flag_get(I2C0, I2C_FLAG_ADDSEND))，地址确认没有问题，时序是跟着手册里的时序表配置的，有大佬知道是为什么吗 代码如下： 初始化 /* 禁用I2C外设 */ i2c_deinit(I2C0); // 禁用从机地址 i2c_address_disable(I2C0); /* 配置时序（100kHz，满足t_VD;DAT≤3.45μs） */ i2c_timing_config(I2C0, 14, 3, 0); // PSC=14, SDADEL=3, SCLDEL=0 i2c_master_clock_config(I2C0, 65, 34); // SCLH=65, SCLL=34 → 周期≈10μs /* 禁用自动结束模式（手动控制STOP条件） */ i2c_automatic_end_disable(I2C0); /* 使能I2C */ i2c_enable(I2C0); i2c_nack_enable(I2C0); i2c_bus_timeout_a_config(I2C0, 0x96); // 超时阈值根据实际时钟调 /* 单字节写入 */ int byte_write(uint16_t addr, uint8_t data) { /* 等待总线空闲 */ while(i2c_flag_get(I2C0, I2C_FLAG_I2CBSY)); /* 配置传输3字节：地址高、地址低、数据 */ i2c_transfer_byte_number_config(I2C0, 3); /* 发送起始条件 */ i2c_start_on_bus(I2C0); /* 3等待地址发送完成或检测错误 */ i2c_master_addressing(I2C0, EEPROM_WRITE_ADDR, I2C_MASTER_TRANSMIT); while(!i2c_flag_get(I2C0, I2C_FLAG_ADDSEND)){ if (i2c_flag_get(I2C0, I2C_FLAG_NACK) || i2c_flag_get(I2C0, I2C_FLAG_BERR) || i2c_flag_get(I2C0, I2C_FLAG_LOSTARB)) { i2c_stop_on_bus(I2C0); i2c_flag_clear(I2C0, I2C_FLAG_NACK | I2C_FLAG_BERR |I2C_FLAG_LOSTARB); return -1; // 错误处理 } } i2c_flag_clear(I2C0, I2C_FLAG_ADDSEND); /* 发送地址高字节 */ i2c_data_transmit(I2C0, (addr >> 8)); while (!i2c_flag_get(I2C0, I2C_FLAG_TBE)) { // 等待发送缓冲区空 } /* 发送地址低字节 */ i2c_data_transmit(I2C0, (addr & 0xFF)); while (!i2c_flag_get(I2C0, I2C_FLAG_TBE)) { // 等待发送缓冲区空 } /* 发送数据字节 */ i2c_data_transmit(I2C0, data); while (!i2c_flag_get(I2C0, I2C_FLAG_TBE)) { // 等待发送缓冲区空 } /* 等待传输完成（TC标志） */ while (!i2c_flag_get(I2C0, I2C_FLAG_TC)) { // 等待发送缓冲区空 } /* 发送停止条件 */ i2c_stop_on_bus(I2C0); delay_1ms(10); // EEPROM写入延迟 return 100; }

外部中断EXTI_IRQHandler间隔启动读数据，中断后CS低电平使能读; 读取指定数量数据后产生DMA1_Channel0_IRQHandler中断，CS高电平结束读； 异常：一般开始是正常读取，如正常波形，运行一段时间后，可能几分钟、几小时后DMA1_Channel0_IRQHandler提前产生中断，即实际并没有读取完毕，图波形图，CS已经高电平了，但是SPI_CLK仍然持续中。 黄色：CS电平 蓝色：SPI CLK [url=/data/attachment/album/202411/29/212341w7bbcc3yplglb7b0.jpg][img]/data/attachment/album/202411/29/212341w7bbcc3yplglb7b0.jpg[/img][/url] [url=/data/attachment/album/202411/29/212342kbdf7rgr9m76ubqt.jpg][img]/data/attachment/album/202411/29/212342kbdf7rgr9m76ubqt.jpg[/img][/url] 相关代码： void EXTI_IRQHandler(void) //定时产生SPI 读请求 { if(RESET != exti_interrupt_flag_get(EXTI_Busy)) { exti_interrupt_flag_clear(EXTI_Busy); CS = CSReadEnable; //启使能，如图低电平 //启动的SPI DMA 中断 读 dma_flag_clear(DMA,DMA_CH_RECV,DMA_FLAG_FTF); dma_flag_clear(DMA,DMA_CH_SEND,DMA_FLAG_FTF); DMA_CHCNT(DMA, DMA_CH_RECV) = AD7606CHCount; //void dma_transfer_number_config DMA_CHCNT(DMA, DMA_CH_SEND) = AD7606CHCount; DMA_CHCTL(DMA, DMA_CH_RECV) |= DMA_CHXCTL_CHEN; //dma_channel_enable，启动DMA读。 DMA_CHCTL(DMA, DMA_CH_SEND) |= DMA_CHXCTL_CHEN; } } void DMA1_Channel0_IRQHandler(void) //读取指定数量数据后产生中断。 { if(RESET != dma_interrupt_flag_get(DMA,DMA_CH_RECV,DMA_INT_FLAG_FTF)){ dma_interrupt_flag_clear(DMA,DMA_CH_RECV,DMA_INT_FLAG_FTF); CS = CSHighZ; //读取完成后，CS至高电平， DMA_CHCTL(DMA, DMA_CH_RECV) &= ~DMA_CHXCTL_CHEN; //dma_channel_disable，下一次外部中断将再次开启。 DMA_CHCTL(DMA, DMA_CH_SEND) &= ~DMA_CHXCTL_CHEN; //接收数据处理 } }

iic中断接收例程中，这个操作是干什么用的 观察寄存器实际还在使能状态，这个个代码看起来没有任何作用，但是不加还不行，为什么

请问SH79F1611 JTAG下载协议 去哪里能获取到？

联合体如下： union SFLAG { struct { uint8_t b0 : 1; uint8_t b1 : 1; uint8_t b2 : 1; uint8_t b3 : 1; uint8_t b4 : 1; uint8_t b5 : 1; uint8_t b6 : 1; uint8_t b7 : 1; uint8_t b8 : 1; uint8_t b9 : 1; uint8_t b10 : 1; uint8_t b11 : 1; uint8_t b12 : 1; uint8_t b13 : 1; uint8_t b14 : 1; uint8_t b15 : 1; } bits; uint16_t bytes; }; union SFLAG Sflag = {0}; 现在想设置b0 位的值，该如何写代码，试用 Sflag.bytes &=0x01; 怎么不对呢？？？ 请高手帮助解决，谢谢！！
