Resolved! Unable to use PC15 as GPIO input
Hello everyone,I'm working on a project using an stm32f030rc. I need to use PC15 as a GPIO input but it appears I'm unable to.I understand the couple PC14/PC15 is shared with the LFE oscillator, but of course I'm not using that function. Moreover, I ...
stm32f767zi max interrupt speed
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...
Stm32f4disci power supply
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.

Using STM32F103C8 chip,Can PC15 and PB11 not use IPU mode at the same time?
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...
Resolved! About Ouput Compare Insert dead time .
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...
TIM1 Complementary output with dead-time insertion not correct ?
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...
Problem with using external crystal oscillator
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...
