SPI Master NSS always low in STM32F4

Posted on March 03, 2017 at 12:34Hi guys!I'm configuring the Nucleo 64 with the STM32F446RE to use SPI as a Master.The problem I'm having right now is that the NSS pin is always low. Clock and MOSI are perfect. What I would like is that the NSS is h...

programming for STM32F302VB.

hi STM,i have STM32F303E-eval board which can me mapped to STM32F302VB mcu i/o lines.how to validate STM32F302VB source code using STM32F303E-eval board.please give inputs.regards,roushan kumar

Hi, Is it possible to reconfigure the programming pins (SWCLK, SWDIO and NRST) as input and output pins and work with them? if I need to reprogram the microcontroller they must work normally. Enrico

Supply external analog circuitry with AVDD?

So, I'm trying to integrate on a Test JIG a NUCLEO-144 with STM32F746ZG on board.It should be possible to draw some current since AVDD (CN10 pin1) is connected through a ferrite bead to the +3.3V (and in the user manual is written that the +3.3V can ...

Polling or Interrupt better for CAN-FD reception

Hi,I have brought a new Nucleo-H743ZI kit. I wanted to receive data from 5 nodes using CAN-FD which transmits at the rate of 5mbps. which is the best method to use Polling or interrupt to receive the data over CAN-FD??Note: each node send 30 kilobyte...
