I have an unusual question. The storage temperature range for an STM32WL is stated as: -65 to +150 °C.We are looking at doing some particular tests at high temperatures for radiation exposure recovery, so some questions if anyone knows:1. If we put t...

We have a newly designed board that uses an STM32F765 up and running. However with the BOOT0 line held high it does not present a DFU interface on the USB_FS port. The USB_FS_DP line remains low. We can run suitable USB_FS code on the STM32F765 and t...

I have been testing the performance of some maths functions on an STM32F407 CPU running at 168 MHz. From the documentation it is stated that the vmul.f32 (HW 32bit multiply instruction) should take 1 clock cycle to operate. Using my simple test progr...

Posted on June 21, 2018 at 05:51It appears, but is not clear from the data sheets, that the STM32F7 and some STM32F4's have two separate USB controllers a FS one and a HS one. Assuming suitable software can be created can these two controllers be us...
