I am using STM32H7A3 for speed control of BLDC hub motor, I also need to take the feedback speed from the driver using stm32 timer input capture mode or external clock source, I have doubt for choosing, Please any help to figure out this.....
I've already become familiar with the NUCLEO-C071 by creating some additional hardware (display, encoder, etc.). Now, I want to design a board using the smaller 32-pin version. However, in this smaller version, I find some differences that I don't kn...
Hi!I was just wondering whether there will ever be a STM32H7R7/7S7 development board commercially available from ST? I do have the STM32H7S78-DK, but it would be very nice to also have a development board with breakouts to all the pins instead of onl...
Dear Sir/Madam,Good day~I am trying to build a custom PCB with an STM32 chip.Currently, NUCLEO-F439ZI Demo Board is used, but only few pins/functions of the STM32F439ZI chip are necessary for me, the used pins shown as below (20 out of 114 pins are u...
Hello,we are developing a device with STM32F765VIHx.We are experiencing a big issue with USB (USB-Device Full-Speed), when connected to a Windows PC.The USB is configured to be a Virtual ComPort.Windows sometimes recognizes the device, sometimes the ...
I am using the STM32H562ZGT to generate center-aligned PWM with TIM1. Since I also want to use TIM1 for 20kHz periodic interrupts, I set the Period so that overflow/underflow occurs every 40kHz and set the Repetition Count to 1. This ensures that UEV...
Edit by ST Moderator: This post has been translated from Japanese to comply with the ST Community Terms and Conditions (§10.2). The question is about the interrupt processing of the STM32F401RE. After the STM32 was started (after the programme was st...
Hello, I have a question regarding write access to a PSRAM connected via XSPI in memory mapped mode on a STM32H7RS. I do not completely understand if having the PSRAM memory mapped makes it available to the ECU as if it is internal RAM, meaning that ...
I am interfacing a 5V PWM signal with an STM32F030K6T6 MCU using PB0. According to the datasheet this pin is 5V Tolerant. In the past, regardless of a pin's "tolerance" to 5V I have always used a level shifter to change this 5V signal to a 3.3V sig...
I am using uart on STM32L07 to simulate 1-wire for operating ds28e22. 1-bit timing is more than 1us and less than 2us. When I set baudrate at 666666 which meant 1 bit timing was 1.5us, I found the rising edge was too slow (more than 1 us). So I want ...
