Hi,I am using a STM32L452RET6 and need to change the PWM frequency (and later the duty cycle) of Timer1 Channel 1 multiple times and on the fly. I tried using the following code but does not change the frequency:htim1.Init.Period = 20000;HAL_TIM_PWM_...
I'm running a USB keyboard on an H743. This works completely reliably at all CPU speeds up to and including 400MHz. However, above 400 MHz the connection is no longer reliable. Sometimes the keyboard connects perfectly and then it will work properly ...
I have been examining the X-CUBE-EEPRMA1 codebase and noticed a couple of issues with the code that is causing delays in the firmware:m95xx.c. Line 344 "pObj->IO.Delay(6);". Is the 6 ms delay necessary? In line 353, the system checks if the chip is r...
I have an STM32L433 that implements a SPI slave, it is connected to another MCU master. It is unclear from the datasheet and searches for answers whether MISO and MOSI on the slave should connect directly to MISO and MOSI on the master, or, if they s...
Hi, We've been using a board (the Daisy Seed) that has an STM32H750IB and external QSPI flash chip.We're having an issue with some of the boards somehow getting into a persistent (across reset. power cycle, and chip erase) state whereby the SCB_Enabl...
I can find the UM1021 document for STM32F105xx, STM32F107xx, STM32F2xx and STM32F4xx, but nothing for STM32F7xx.Any help would be appreciated.Thanks
hello everyone i'm working on stm32h742 from two week but i'm not make it configure it anyone can help me i'm not able to communicate with lan please provide me some guidence i tried many tutorial on ethernet but its not working att all kindly sugges...
I have planned to connect my custom flight controller to the ground station(mission planner) for that i have connect all the necessary connection usb connection also and flashed the pre compile firmware of matekf405 from here: https://firmware.ardupi...
Hi,where do I find the full HAL API documentation? Is there a wiki? And also is there a way to pull it up in CubeIDE (I'm not referring to the autocomplete)? Also is there a repository with all examples organised by topic, for example PWM, I2C etc.? ...
As title says.If so, where could I find an example.If not, will it be supported?
