IPE6.25 ICD5 CONNECT点击后出现如下错误： MPLABComm USB Version: 3.48 MPLABComm Serial Access Version: N/A ***************************************************** Transmission on endpoint 2 failed (err = -109) You have set the program speed to Normal. The circuit on your board may require you to slow the speed down. Please change the setting in the tool properties to low and try the operation again. Failed to get Device ID. Please make sure the target device is attached and try the operation ag 请问要怎样解决？

我用PICKIT5 V625 verify PIC24FJ128GL405T [ Pgm ] at 0x281a, expected 0x0025fe00, got 0x0025fb40. You have set the program speed to Normal. The circuit on your board may require you to slow the speed down. Please change the setting in the tool properties to low and try the operation again. Verify failed The following memory area(s) will be verified: program memory: start address = 0x0, end address = 0x15eff configuration memory [ Pgm ] at 0x281a, expected 0x0025fe00, got 0x0025fb40. Verify failed 报这个错误，重新program pass 然后verify 也pass，再过一会再去verify 就出现上面的问题。 重新修改双绞线，等都不行。求大神支招。

我在用 AT32F421_MC_Library_Project_V2.1.4 pmsm_foc_sensorless这个工程 用SPMSM -sensorless (Open Loop) 模式 Speed Control 速度模式 当我启动后，电机旋转 用手用一点力就能让电机停止，然后报错startup error 我现在不知道 电机是否进入闭环，因为报错startup error 如果进入闭环应该是报错 过流吧 谁能帮我解释一下 或者是什么原因导致的 感谢

有哪位大佬知道，GD32F30X的 系统库函数timer_init()里没有对TIMER8/TIMER11的处理， 是什么原因？void timer_init(uint32_t timer_periph, timer_parameter_struct* initpara){ /* configure the counter prescaler value */ TIMER_PSC(timer_periph) = (uint16_t)initpara->prescaler; /* configure the counter direction and aligned mode */ if((TIMER0 == timer_periph) || (TIMER1 == timer_periph) || (TIMER2 == timer_periph) || (TIMER3 == timer_periph) || (TIMER4 == timer_periph) || (TIMER7 == timer_periph)){ TIMER_CTL0(timer_periph) &= ~(uint32_t)(TIMER_CTL0_DIR|TIMER_CTL0_CAM); TIMER_CTL0(timer_periph) |= (uint32_t)initpara->alignedmode; TIMER_CTL0(timer_periph) |= (uint32_t)initpara->counterdirection; } /* configure the autoreload value */ TIMER_CAR(timer_periph) = (uint32_t)initpara->period; if((TIMER5 != timer_periph) && (TIMER6 != timer_periph)){ /* reset the CKDIV bit */ TIMER_CTL0(timer_periph) &= ~(uint32_t)TIMER_CTL0_CKDIV; TIMER_CTL0(timer_periph) |= (uint32_t)initpara->clockdivision; } if((TIMER0 == timer_periph) || (TIMER7 == timer_periph)){ /* configure the repetition counter value */ TIMER_CREP(timer_periph) = (uint32_t)initpara->repetitioncounter; } /* generate an update event */ TIMER_SWEVG(timer_periph) |= (uint32_t)TIMER_SWEVG_UPG; }
