Hi All,We are having issue on stopping interrupt while doing Flash Erase.What we are doing:1. Unlocking flash.2. Entering Critical Section by disabling ISR.3. Erasing a Flash Page.4. Waiting for operation to complete by checking busy flag...
I have viewed every example on the internet, I think and seen many different commands and approaches. As long as the interrupt is disabled, the program works, but it crashes when enabled. Here are snippets related to EXTI. Maybe I have mixed code fro...
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.
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...
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...
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.
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
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...
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...
