Dear all, I am developing motor control system, and would like to observer the (motor) current response. In the past, the method I often used was DAC, where the current command and actual value were output separately through the DAC to an oscillosco...

Dear All, I want to use STM32CubeMonitor to monitor 64-bit variables, such as int64_t or uint64_t. However, it seems that 64-bit variables cannot be selected from the variable list (they are not displayed).Is there any way to achieve this?Best Regard...

Dear All,I've been using MCU/DSP-related products for over 10+ years, but I've always had some confusion about clock multipliers and dividers. I'd like to ask for everyone's opinion on this topic.As shown as below figure (it's the clock configuration...

Dear All,I am developing a motor control system(FOC) with STM32H5.In the FOC process, while completing the ADC conversion for current measurement, it enters the ADC interrupt, where I read the TIM2 counter(for Encoder interface) to obtain rotor angle...

Dear Sir,When I monitor the data, sometimes the value often accompanied by spikes, such as followed figure. In my case, I monitor 3 variables that update from ADC registers.Normally, their values would be around 0.The signals of ADCvalue[0] and ADC V...

Hello Andrew,Thank you for your comments.1. The following is my communication protocol. Its packet length is 14 Bytes.(The original data content is 4 bytes, but the entire packet includes SOF, EOF, some CRC, and a device identifier.)Thus, each packe...

Hello Waclawek,Thanks your opinion, It's good advise to me.I have another ideal, maybe we can use TRGO to trig DMA, and transfer the data from TIM2.CNT to my variables.The advantage is that there's no need to go through capture.(CH3/CH4)It seems like...

Hi, Stephane, I totally understand via your reply.This is a good explanation. I am very grateful

Hello TDK, I think what you said makes a lot of sense. It might really be caused by the fact that it's transmitted as two separate bytes. Thank you for sharing your opinion.

Additionally, if I add monitoring of other values, there is a chance that the data will return to normal.For example, as shown in the image, I added two more monitoring variables, offset[0] and offset[1].At this point, ADCvalue[2] returned to normal....
