Using STM32F4 Discovery board to control AC servo motor driver

Hi All,I'm trying to interface the STM32F4 Discovery board with an AC Servo drive. So basically, I have this hex file of a closed source firmware, whose function is to, on one side, interface with PC through USE port, and on the other side, send PWM ...

Resolved! How to recover an STM32L43KC based Nucleo's St-Link functions?

I'm new to the Cube toolchain and am attempting my first program. TIM2 is configured for PWM so I put a scope on one of the pins as a test the program runs but saw nothing. I had forgotten to remove the jumper, so I removed it to enable execution, bu...

STM32F405: Can we use Port A0 (T2.1-ETR or T8 ETR) to trigger a capture on Port A5 (T2.1-ETR or T8.1)?

When we enable the RTC feature on our controllers, we do a calibration in Production against a GPS-locked 10MHz signal. Usually, we'll use the T2 ETR to clock the 10MHz signal in and an RTC-generated 1Hz signal on one of the other T2 channels such a...

Resolved! Timer encoder mode not counting

I have a project with a rotary encoder and I'm trying to use one of the timers in encoder mode to keep it's position but I can't seem to get it working and I don't know what I doing wrong. Any help would be much appreciated, if any more information i...

Hi, I bought a Nucleo STM32F401RE board. Yeasterday the board was working fine in dimming led in A0 pin which was configured in PWM mode. Now I can't reprogram the board. See details for error message. PS. I'm a total beginner with microcontrollers

Starting server with the following options: Persistent Mode : Disabled Logging Level : 1 Listen Port Number : 61234 Status Refresh Delay : 15s Verbose Mode : Disabled SWD Debug : Enabled InitWhile...

Resolved! Development board for STM32L475 to work on capture module

I want to test on the capture module to find out the pulse width of arrived pulses at timer pins in my real application. So, here I want a development board for the STM32L475 to work on this application like generating pulses from one-timer PWM and l...

Resolved! Odd encoder filter behavior

I'm using a Nucleo-F746ZG with timer 2 as a quadrature encoder input. I'm feeding it quadrature signals from 2 GPIOs at 250Hz (each phase is 1mS).The CDR value is 0, so FDTS should be CLK_INT (36MHz for APB1). With both inputs' filter set to 8, the...

I am using stm32f373cct6. I want to start & stop timer using external input. Is it possible by hardware?

Code misbehaves when debugger is not connected

Hello All,I am using STM32F030C8, with ST-LINK V2 debugger & Keil V5 IDE.While working on my application, I found two cases, where some logic / functionalities works properly only if we are using debug session. Else, those functionalities doesn't wor...
