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...
hello.Using STM32G0B0CET6USB_DRD_FS---Host_Only_FS,USB_HOST---Mass Storage Host Class,FATFS---USB DiskUSB Interrupt---EnableIf you set it to the above mode and operate it, the USB is recognized only once when the power is first turned on, and the USB...
I'm trying to connect an encoder with STM32F407VGT6. The encoder sends out A,B and Z pulses out. I can read both A-B and Z pulses using TIM2 and TIM3 respectively. Timer 2 is in encoder mode and TIM3 is in input PWM mode. I want to know if I'm correc...
I have a STM32G030K8 processor that needs to write some stuff to memory as soon as it detects that it will be losing power - always a bad time but I have to do this.Most of the time it seems to be doing this just fine but once in a while the processo...
hi Team,Have configured PA11 and PA12 as USB_DM and USB_DP respectively.Further , How to configure USB VBUS in STM32H523RETx LQFP64? Regards,Deep_Bang
A while ago a member of ST staff kindly helped me on this forum with adding EEPROM emulation to my design (at the time based on Nucleo-F401RE) by directing me to here....https://github.com/STMicroelectronics/STM32CubeF4/tree/master/Projects/STM32F4-D...
Hi,There seems to be an error in the reference manual RM0481 Version 2, page 264, table 48.In the circled image I believe this should be 0x08040000. Can you anyone please confirm my deductions?Kind Regards,Shane
Is it ok to keep unused peripherals in perpetual reset, by leaving their RCC_APBRSTR_*RST (or similar) bit set?Maybe differences in power consumption?This is not for a specific STM32 family.I'm just looking for advice by people with more experience, ...
