Hi--I/m pretty stumped. I am trying to implement a odd parity configuration for USART1 in an stm32L452RE micro. I've confirmed without parity the usart behaves as expected at the needed baud. When i introduce parity into the code and sniff the data o...
Form, Fit and Function Alternate for Part STM32F070RBT6 as this is not procurable at the time, we need an alternate that can fit into design without any software or hardware modification.
HiI'm using the HAL_SPI_TransmitReceive_DMA to write to an external Flash. On a delte command for the external flash I need to wait for until the busy flag of the flash is zero. So I use this function to check the busy flag. spi_read(&command, sizeo...
Hello everyone, I use a STM32F407VET6 MCU board and I'm trying to implement a Timer 8 Interrupt, every 5u sec. In my code, I also use an ADC interrupt, for ADC conversion purposes. I thought that these 2 interrupts are independent. I observed that w...
HiI've set the jtag pins in my code to analog input (non intentionally) .While I was able to connect to Device (STM32H743) after I managed to erase the flash option bytes (with mass erase) using j-link stm32 tool (No St-Link option or SWD for me on ...
Hi,I have some code running on a Nucleo-STM32L476 which keeps running into the Reset Handler. But this does not cause a boot loop, instead the code just gets stuck there (the PC register points to the first line of assembler of the reset handler).I m...
Hello everyone, I am trying to read one pin with the HAL libraries, but i can not. This is my configuration: 1) I want to read the "BUTTON" pin ( PB3/PB4/PB5/PB6 ) 2 I am doing this: GPIO_InitStruct.Mode = GPIO_MODE_INPUT; GPIO_InitStruct.Pull = GP...
Hello. I have a question about the correct use of GIPO_Analog.wanted to read this value.I also want to know if the value can vary between 0 to 4095 as when the ADC is used.am I using an MCU that I use Nuclo-F446RE?
Hi, I am new to using 32 bit microcontrollers and have been using 8 bit controllers previously. In my 8 bit controllers I had several uint8_t and uint16_t variables.Does a 32 bit microcontroller access 4 bytes of data in memory at once? If yes, can t...
