I would have a question I am using stm32f767zi and trying to capture 2mhz signals with interrrupt600 700 khz is not much trouble, but 1mhzlerde starts to catch the deviation. Captures the rising and descending edgeI wonder how another method can be a...
I find a question. when I try to change the power for computer's USB interface to an extern 5V.it doesn't work.LD1 keep flashing.but when I use the computer's USB.it works well.what's wrong. I use it to produce a pwm.
Dear ST Expert,Our customer needs our support to program STM32F050K4U6（QFN-32）chip, but HI-LO RD can’t get the corresponding datasheet, pinout diagram and programming specification from ST website. We deeply appreciate that you can help to provide ...
I used STM32F103C8 series of chips, now I design four keys, the corresponding IOs is PC13,PC14,PC15 and PB11. The problem is that PC15 and PB11 cannot be used as input at the same time.As long as these two pins are not input at the same time, the res...
Now , I generate below waveform. Every thing is OK except for red arrow , it indicate a deadtime.but it's longer than other deadtime , in fact , This dead time is twice as large as the other dead time .divide into three stage :1�?First Stage , TIM r...
Hello , now I debug about Complementary output with dead-time feature of TIM1 CH1 and CH1N, I set deadtime 5us ,and TIM1's period 50us , then I get scope via oscilloscope ,but the scope is not what I expect , refer to below , In fact DT1 == 2...
Hi Everyone,We are using the following code to generate clock pulse for STM32F722 from an external 12MHz crystal. However, whatever we do it sounds the STM32F722 gets its clock pulse from an internal 16 MHz oscillator. The reason for using an extern...
I am using a Nucleo F429ZI. I have noticed when I plug it in via the debugger, my computer treats it like an external drive (which it calls NODE), where it seems I can store stuff. Is it possible to store a text file in this space generated from my p...
Hi there, I'm using the SAI2_FS_A signal to trigger a capture event on TIM2 (Through a series of weird internal routing). It all works nicely when SAI2 is an asynchronous master, however in my application it needs to be a synchronous slave to SAI1. I...
Hi there, I'm using the STM32H7 and I need to get one of the SAI FS signals to go through a pre-scaler and trigger a capture compare on TIM2 CC3.The only solution for this seems to be to use SAI2_FS_A -> TIM5_ETR1 -> TIM5_TRGO -> TIM8_ITR3 -> TIM8_TR...
