Hey everyone.In my project, I want to reserve some flash sectors to write data that I don't want erased when flashing new code on my processor.So I changed the .ld files to reserve my memory as follow :M7 files :STM32H755ZITX_FLASH.ld and STM32H755ZI...
I'm using the HAL_UART_Receive_IT function on stm32f303re to recieve data. After each use I want to delete the content of the receive buffer so that the next data that will arrive will start at the first index of the array. Is there a function to del...
I'm using MSIS at 24 MHz for everything, like this: SET_BIT(RCC->CR, RCC_CR_MSISON); while (0 == (RCC->CR & RCC_CR_MSISRDY)); SET_BIT(RCC->ICSCR1, RCC_ICSCR1_MSIRGSEL); MODIFY_REG(RCC->ICSCR1, RCC_ICSCR1_MSISRANGE, RCC_ICSCR1_MSISRANGE...
I want to use CAN Bus in STM32F042F4 (TSSOP20). In the data sheet it says, CAN_RX on PA11 Pin 17, CAN_TX on PA12 Pin 18.When trying to configure in CubeMX, CAN function is greyed out and the pinout has not PA11 and PA12. Isn't it possible to use CAN ...
I am currently working on a project to program a PLC. This one already has a program to control its operation. We are using the Nucleo board STM32F302RBT6. The goal is to extend the program to be able to integrate the uart communication. Unfortunatel...
Hello I m trying measure adc conversion time , I look datasheet , f_adc=37 Mhz(for fast channel) with 12 bit resulation, 4.10 MSps , so ı use f_adc=32 Mhz(for fast channel) with 12 bit resulation, 3.54 MSps should be, but I m not measure 3.54 MSps,I ...
I am having issues getting the status flag polling mode to work when I try to poll with a QuadSPI command that uses all four data lines for the instruction. When using a command with a 4-line instruction in this mode, it polls the first command corre...
Hi, I am looking to read 16bits which are split between port A and B on an interrupt hooked up to exti0. I *seem* to have the dma working and see the expected data at DMA completion (interrupt). However the DMA controller does not react to the interr...
Hello, I have a Nucleo L476RG which I'm using for different projects, and I never gave an importance to the offset addresses that are written before every register in the reference manual.Can anyone explain to me what are theses offsets.
