Hi.We use a STM32F431 in a project and need to add/include a MCU-port to generate a fixed 200kHz output signal to our target-HW. Many pins on our LQFP64 are already used, so I hope I can use PB6 (TIM16_CH1N) for that purpose.Q1: How can I set up a (p...
Hi , I have an application that streams multiple audio sources over USB device Audio class to PC. The PC detects audio device and the streams work.I'm building hardware based on X-CUBE-MEMSMIC1 and don't want to use a second micro ( st-link ((stm32f0...
Hi(All?) my nucleo board(s) is/are detected as a USB device in windows. I can drag and drop a firmware binary on them. And the Firmware is automatically updated after power cycling the board. I want to design my own board and use the USB to update t...
Hello,I dont't know why in my projetc the PWM daoes not start.I would generate a PWM with Duty =50% and Period =10msec. I use a NUCLEO--F303RE.I started with CubeMX to generate the project configuring IO (blinking the green LED) and the PWM on TIM1 C...
Hello.I have a nucleo powered with external 5V. I use to log info using usb.Eache time i need to talke a log to the log, i cannoct my laptop and MCU reset.Anyone know if i can hovoid this? Remove SB12 could help Me? any other hint?Regards,Carmelo
Helloi want to exit from STOP mode using RTC has in the example of STM32Cube\Repository\STM32Cube_FW_L4_V1.12.0\Projects\NUCLEO-L476RG\Examples\PWRBut the STM32 exits immediatly after the WFI execution.It works well with the HAL_PWR_EnterSTANDBYMode ...
All other GPIOS work but these two do not. They get the same voltage as the rest (0 and 3.2V). All pins Vdd and Vss I have them well except pin 97 VDD_USB that by mistake I have connected to GND.I have attached the project with which I have been test...
Hi all, I have a problem to show float numbers via sprintf, I'm working with STM32F334I did a program to print via serial the voltage read from ADC, in float format like %4.2f, the problem is that the first time the sprintf generate a valid string wi...
Hi，Masterplatform:stm32f030C8TxI saw the data sheet as described below:My schematic is as follows:These LED lights can be lit at the same time, the program can also run normally, but their current sum has exceeded 3ma. Although it violates the descri...
