Hello ST community,I have some troubles using Quad-SPI interface in STM32H7 micro.I need to communicate with a custom part using quad SPI mode (4 data lines). The interface is configured for indirect mode and DMA is enabled.In a super-simplified case...

Hey guys,I'm trying to understand STM32F334 high resolution timer (HRTIM) in some details.It says the timer has 217 ps resolution. But how can I achieve that in practice? Let's say I generate PWM signal with 1MHz frequency and 500.00ns pulse width. (...

Posted on December 17, 2011 at 18:26Has anyone try to implement USB host for full-speed HID joystick (like Logitech)?I try to use code from STM32F105/7 and STM32F2xx Host and device library (UM1021). It works fine with low-speed joystick (noname), b...

Thank you for your reply, I appreciate it too.Unfortunately in my case I'm communicating with FPGA, so the protocol is not a real regular Quad SPI intended for memory chips.

Wow! Thank you so much for 100% accurate answer! Now it is clear.I will leave it here for the future:

I indeed have such a scope to be able to see the time resolution beyond 1ns.The problem is that I cant program HRTIM to get this.

Hi waclawek.jan,Thank you so much for your reply and your attention to my question.Have you ever tried HRTIM by yourself?Since it seems like it is impossible to observe 217ps resolution directly, are there any other cues which can indicate a presence...

Posted on October 22, 2017 at 19:58I'm working at big US automotive manufacturer.And the automotive STM32 is my biggest wish. Hopefully someday ST will do AEC-Q100 certified STM32F4 or similar chip. At the moment we are stuck with SPC and STM8, whic...
