Resolved! STM32H7 code break after upgrading from 1.3.0 to 1.5.0 Firmware package
My STM32H7 firmware was working and compiling fine before I upgrade my CubeMX firmware package from 1.3.0 to 1.5.0.It seems that the GPIO register struct has been changed and "BSRRH" and "BSRRL" members of the struct do not exist anymore! So my code ...
Can not enter DFU mode when DFU code combine with app code
I use cube to generate DFU code and test its function. It is fine(device can enter DFU mode).But after I download APP code to 0x0800A000, then test again. Device can jump to app successfully but device cannot enter DFU mode. Device descriptor reques...

STM32F107 FreeRTOS+NetConn won't work
Hello.I'm trying to stitch-up the STM3210C LwIP TCP/IP Echo client example (my board) and STM324xG LwIP+FreeRTOS+NetConn example.LwIP, and netif config are the same as for Echo example (and previously I ran httpd-raw server with it).I was able to set...
Does anyone know how to get sink capabilities using the STUSB4710?
I'm using the evaluation board ISC004V1 and using the GUI STUSB001 I noticed that you can get the sink capabilities when there is a load connected. I suppose that this is done by sending a message to the load and to do that I think you have to write ...
Inaccurate us delay function
Hi,I'm trying to implement a `delay(microseconds)` function on an STM32 F745 running at 216 MHz. I want to keep it dummy and simple without involving interrupts. My strategy is as follows:-Setup TIM2 to run at 1 MHz. Since it has a 32-bit counter it ...
