Resolved! STM32F405 Can not connect to target
Hello All, I Hope you are well.I am facing a problem that I spent A LOT of time on. I designed a custom board featuring the STM32F405RGT6 but i cannot connect to it at all.. I will attach the schematic and the board's pictures below. (The schematic i...
STM32F4 Using FileX : Can It Be Used Independently?
Hello, community! I'm a new here .I am developing STM32F4 using STM32CubeIDE（1.14.1）, and I want to use the FileX without ThreadX. However, it seems that this is not possible in CubeMX. The FileX for the F4 series requires ThreadX, and if ignored, t...
Single word flash programming is not properly write the memory and disturbed multi write
Hi, I work in the stm32h503rbt6 controller, I use an internal clock 64Mhz and developed the Flash driver on my own and also works well in multi-word write only, single word write is not working, it is not writing the data in Flash memory(in single wo...
Resolved! 8 pulse pin outputs on the STM32F407 (Drive GPIO with basic timer?)
Hi, I have an application where I need to send send signals to 8 stepper drivers on my STM32F407 Discovery board. Each stepper driver requires an independent PULSE, DIRECTION, and SLEEP signal. DIRECTION and SLEEP are trivial GPIOs high/low. I have u...
STM32H7A3 USB-C connector wiring, lack of USB details in datasheet
I'm attempting to wire a USB-C connector to the deluge of strangely named pins available on the STM32H7A3VIT6 (100pin LQFP). Pin names STP, NXT, CK, D0 thru D6 are available on the H7A3 via CubeMX but I'm not able to find information on pin function...
STM32H7 3 Phase Current measurement with DMA with precise location defined by HRTIM (problem)
Hello,In my project I need to sample 3 phase current to see if where is short or not. I am using STM32H753 HRTIM. Not only that I must place sampling point as close to PWM transition from high to low as possible (peak current)I connected phase curren...
I2C multibus on alternative pins howto or is possible?
I ask for this , but any other same alternative use.i set primary I2C on PB10,11 as on image an reserve PA10,11 and PF0,1My plan is use alternative AF as I2C switch similar as IC PI4MSD5V9540On PF pins is device on 5V I2C . In code i try add to one I...
STM32F429ZIT6 SPI Receive Issue
Hi everyone,I'm currently using the Nucleo F429ZI development board to test SPI Receive, and I've encountered the following two issues:I use the HAL_SPI_Receive() function, when I config the SPI frequency to a slower rate, I've observed that the CS s...
Resolved! G431RBT6 - Interfacing timer and compare output timer have rather fluctuation timings
I have timer 1 to use with hall sensors as interfacing timer. Timer 8 is then used to output the signals (see picture red and blue).The simulated hallsignal (3 sensors combined) is very precise and pretty constant (green signal - second box)."A" show...
