MM32SPIN06的IWDG中断不生效，已经配置IWDG 溢出后产生中断 ，NVIC中使能IWDG中断，可是 IWDG 溢出后没有产生中断，而是复位了MCU

当GD32作为主机和从机进行SPI通信时，输出的NSS片选信号（比如下降沿），和输出的SCK时钟信号（相邻的上升/下降沿），之间有没有时间间隔要求？求各位大佬帮帮忙，谢谢！ GD32的datasheet中，MCU作为主机的情况下，输出的NSS信号没有作详细的解释。 也就是说，怎么去设置这个NSS跳变的时间，才能让MCU作为主机在MOSI线上输出的指令能被从机正确识别？

PIC32MX534芯片调试时全局变量无法赋值，初始值为0XFFFF,使用赋值指令没有作用，值不改变，在其他位置没有使用，也没有赋值。哪位知道怎么解决。

在注释掉PA1作为外部中断的配置语句后，debug可以正常运行。求助下论坛的高手们，我这个中断配置有问题吗？debug出现异常的原因可能在哪？ void AD_GpioInit(void) { /* 配置时钟 */ rcu_periph_clock_enable(AD_GPIO_CLOCK); rcu_periph_clock_enable(RCU_CFGCMP); /* 配置PA1 */ gpio_mode_set(AD_GPIO_PORT, GPIO_MODE_INPUT, GPIO_PUPD_NONE, AD_GPIO_PIN); /* 将PA1映射到EXTI1 */ syscfg_exti_line_config(EXTI_SOURCE_GPIOA, EXTI_SOURCE_PIN1); /* 配置EXTI1 */ exti_init(EXTI_1, EXTI_INTERRUPT, EXTI_TRIG_BOTH); exti_interrupt_flag_clear(EXTI_1); nvic_irq_enable(EXTI0_1_IRQn, 2, 2); }

我在使用CAN通讯时，设置的CAN节点波特率为1MHz，采样点为75%，具体配置见图片，但是在使用测试设备测试单个节点的时候，测出的采样点只有35%。请问是我配置有问题吗，除了截图中的配置还有没有要配置的地方，麻烦大佬们答疑解惑，万分感谢！APB1上的时钟频率为60MHz。

大家好，我需要用ATtiny3217的DAC功能输出一个0-3.3V的模拟量，但是该款MCU没有3.3V的挡位，然后选择了4.3V的挡位给单片机供电3.3V，效果最高确实是只能最高输出3.3V电压了。不知道这样操作会不会存在什么隐患，**各位大佬能帮忙解下惑。

型号AT32F407，在USART2 DMA发送数据时，接包已经接到了要发送的数据，但是程序还是处于等待传输完成的标识判断中，卡死了。请教一下是什么造成的？

在程序中禁用了jtag-dp + sw-dp，导致程序无法下载，不能只禁用jtag吗，为什么都禁用了，如何打开，恢复下载加入了以下代码： crm_periph_clock_enable(CRM_IOMUX_PERIPH_CLOCK, TRUE); gpio_pin_remap_config(SWJTAG_GMUX_100,TRUE);
