目前调试了一个版本，DMA更改占空比时会出现第一个占空比丢失的情况，比如占空比位[16,16,16,44,44,16,16,44,44],输出的PWM波形会出现只有[16,16,16,44,16,44]这样的，每次占空比值变化时就会丢失。 求一个可用的程序。

HC32F4A0,timer4_1输出U,V,W互补pwm信号的软件demo,有参考的吗？

参照GD32例程写了一个使用定时器对外部脉冲进行计数，无法正常运行，通一个芯片，使用STM32的库，ETR计数没有问题，求解

TIMER0用于电机驱动的3路PWM互补模式

需要让一些数据可以掉电保存，于使将这些数据写入到flash中，设置一个timer隔一段时间溢出，在写flash期间中断无法进入

在使用GD32F450单片机中用高级定时器timer0和timer7产生PWM是没有出现pwm信号，到底是什么原因呢？这其中有什么特别需要注意的吗？

做一个简单的呼吸灯，使用advance Timer的比较输出做PWM来使用，通过调整GCMxR的值来改变PWM的占空比，从而改变灯的亮度。现在遇到的问题是灯偶尔会亮闪一下，请问在其他定时器中断中不能更改GCMxR的值吗？？

如题，用的是TIMER2的输入捕获，能进中断，但是用timer_counter_read(TIMER2);函数读出的值与仿真中CNT中的值差别非常大IO的初始代码 /*config input capture io alternate */ gpio_mode_set(GPIOB, GPIO_MODE_AF, GPIO_PUPD_PULLUP, GPIO_PIN_0|GPIO_PIN_1); gpio_af_set(GPIOB,GPIO_AF_1,GPIO_PIN_0); gpio_af_set(GPIOB,GPIO_AF_4,GPIO_PIN_1); TIMER2初始化代码 void timer2_inital(void) { timer_parameter_struct timer_parameter; timer_ic_parameter_struct timer_ic_parameter; rcu_periph_clock_enable(RCU_TIMER2); timer_parameter.alignedmode = TIMER_COUNTER_EDGE; timer_parameter.clockdivision = TIMER_CKDIV_DIV1; timer_parameter.counterdirection = TIMER_COUNTER_UP; timer_parameter.period = 0xffff; timer_parameter.prescaler = 24; timer_parameter.repetitioncounter =0; timer_init(TIMER2,&timer_parameter); timer_ic_parameter.icfilter =0; timer_ic_parameter.icpolarity = TIMER_IC_POLARITY_RISING; timer_ic_parameter.icprescaler = TIMER_IC_SELECTION_DIRECTTI; timer_ic_parameter.icselection = TIMER_IC_PSC_DIV1; timer_input_capture_config(TIMER2,TIMER_CH_2,&timer_ic_parameter); /* enable and set TIMER2 interrupt */ nvic_irq_enable(TIMER2_IRQn, 1U); timer_auto_reload_shadow_enable(TIMER2); timer_interrupt_enable(TIMER2,TIMER_INT_CH2); timer_enable(TIMER2); } 请大侠们诊断下，问题出在什么地方

按照指南操作静态码调试正常，在我的板子上从Touch key Tool Menu图表窗口可以看到手触摸的时候波形变化，也成功变成绿色，但是不知道怎么调试动态，因为静态是用的他们官网下载的静态码直接烧录就可以了，而动态没有直接烧录的码，要从自己的代码里面做进去，就复杂了，按照他们指南操作下来弄了一天硬是一点反应没有，求大哥大姐指导： //************************************************************ // Copyright (c) 深圳市赛元微电子有限公司 // 文件名称 : main.c // 作者 : Yanni // 模块功能 : SC91F8311触控DEMO // 最后更正日期: // 版本 : 2015-12-25: // : //************************************************************* #include "h\SC92F836XB_C.h" #include #include "h\data_type.h" #include "lib\SensorMethod.h" #define _TOUCHKEY_DEBUG_ #ifdef _TOUCHKEY_DEBUG_ #include "SOC_DebugTouchKey_Lib\SOC_DebugTouchKey.h" #endif #define nop _nop_(); //???
