STM32F7 How to get 50MHz on GPIO
I can only get the GPIO pin to toggle at 8MHz but datasheet indicates 108MHz is possible.I tried changing OSPEEDRy[1:0] but this did not help, I only get the default 8MHz.

HAL_UART_Receive_IT with FIFO enabled does not work. STM32H753
What am I doing wrong, or is it a bug in the HAL library?Generated a project with CubeMX, with USART6, FIFO enabled.When I call HAL_UART_Receive_IT, interrupt of the USART does not occur. No interrupt at all.Then I change in MX_USART6_UART_Init HAL_U...
Resolved! What does the data at the end of the inserted code mean when downloading the code?
Hello, everyone.I downloaded the code to STM32H753 and then used STM32 Community to look at the data on the flash memory and suddenly I got one question.I downloaded my code on flash memory bank 2 sector 0 (address 0x08100000) and found that the data...
Resolved! More RAM (and FLASH) for STM32L4 LQFP 48 pin package?
It would be great if the STM32L4 LQFP 48 pin package came with more RAM (and FLASH). The STM32L4 LQFP 64 packages have up to 320K of RAM.
Resolved! STM32 ADC multiple channels HAL
Can some one tell me why this do not work?I start to freak out -.-..........I wish make 4 chanel adc with dma.Best Regards,Szymon
Is there any known issue with I²C and external interrupts (buttons)?.
I'm using an STM32F103CB device, with a OLED screen in I2C1 (PB7 and PB6). The MCU freezes (hard fault) when an IRQ come from an edge in PB5, PB4 or PB3. I suspect that theres is a problem with the IRQ enabling function, which includes the I²C pins i...
STM32F103C8T6 SWDIO/JTMS (SWD/JTAG pin) on pin PA13 still high after disabling?
I'm working on a project that uses lots of GPIO pins for inputs- it uses A12, A13, and A14 as inputs, along with several other pins.I have looked at the reference manual, and A13 and A14 are JTAG/SWD pins.On reset, A15 is pulled high for the JTAG int...
STM32F103C8 and I2C CMSIS problem to access to my MPU9250. Please help.

Resolved! STM32L552-EV, attempting to IAP program the flash through UART connection, however always fails to send the bin file through Y-modem protocol.
I've been using the example AN4657 and following it to a T. I'm using the example project library files form the STM32L476G IAP_Main and modified them where necessary to work with the 552.I can successfully connect to TeraTerm via usart3 connection a...
ADC to DAC using DMA
If I set my sine wave generator to 1.5 Vpk-pk the DAC outputs a nice clean sine wave. If I increase the ADC input above that level, I start to see clipping of the sine wave. The negative part of the wave begins clipping before the positive part. Is t...
