I use timer with input capture mode, to be able to measure time period of an optical encoder pulse. I experienced that measured value rarely is twice as the expected one. I tried with different timer prescaler values, but same problem remained. Suspe...
Hi, I am using STM32G0B1 MCU for my project. Is it true each STM32 IC has its own unique ID. For STM32G4 product has the UID facility. Is it 96-bit ID for all the stm32 families or is it different. Which manual has to be referred for this?If yes can ...
Hi All,Not so long ago ST has selected Microsoft ThreadX as one of its its strategic technologies.In my opinion it is a very good RTOS. The problem is that it was supported by Microsoft only, no other community project integrates with it, e.g. mcuboo...
Hi The MCU is a STM32H735I will use the UART3 port for combined debug output and command line interfaceSo I would like to use the FIFO, it quite useful when sending debug data.The Fifo is also useful for RX, if e.g. interrupt is blocked by other inte...
Hi!Why can i not disable the protection? I use W25Q256. I can't write and erase the flash ic.The programming was working, but suddenly an error occurred during download. Here I noticed that the bits of SR 1 went to 1 and I can't reset them.What could...
I am working on NUCLEO F446RE, I need to use CAN1 and CAN2 on the STM32 NUCLEO-F446RE board. I tested CAN1, which works normally for sending and receiving data, but when I tried CAN2, it didn’t work at all. I looked for solutions in https://community...
I am working on the STM32H7B3I-DK and needing to use PA0_C PC2_C and PC3_C as part a button scanner, as all other pins are being used. I have PA_0 configured as an output and PC2_C and PC3_C as Inputs with pull downs. The current full 3x3 configurati...
Posted on September 23, 2013 at 16:03Hy all, I've a question about the RMII mode at STM32F4 mikrocontrollers. I checked the datasheet and the stm3240g-eval user guide. So the eval board user guide say that at page 19:''In RMII mode the 50 MHz clock...
Hello, I have a question to ask regarding a problem with the STM32H7S78-DK card and using FatFS for an SD card, using RTOS.I try to describe the problem in as much detail as possible.I have my own application which includes TouchGFX among other thing...
