I'm creating code for an STM32L073 that will connect to another system. The final boards are not done yet (and will not be for a while) so we have a Nucleo board that we will be wired into the demo board for the system. I made a spreadsheet with the ...
I was reading in "Mastering STM32" and in the intro of PWM pulses (pg355 hard copy) said that "The square waves generated until now have all one common characteristic: they have a Ton period equal to the Toff one. For this reason they are also said t...
i dont know how to send variable size data evrytime. The HMC Mode protocol for the serial port is designed for a 4 wire interface with a fixed protocol featuringa. 1 Read/Write bitb. 6 Address bitsc. 24 data bitsplease need yout help on how to send >...
Hi Folks,i'm working with the STM32H750 controller. At the moment i'm trying to get the ADC working with the DMA in a Peripheral to Memory Mode. Since i've no idea how to do this, i've started to checking the HAL functions and found the HAL_DMA_Start...
Hi, bom dia.I need to use LPTIM as a pulse counter in stm32L431. I created a project using stm32cubeIDE and start only the necessary to test the LPTIM, but when i call HAL_LPTIM_Counter_Start() or HAL_LPTIM_Counter_Start_IT() never return HAL_OK. I h...
HiI am using a STM32L452 MCU with a quadspi flash from Micron.I configured the board using CubeMX and have tried making a test code based on the example in: STM32Cube_FW_L4_V1.15.1\Projects\STM32L476G-EVAL\Examples\QSPI\QSPI_ReadWrite_DMAI'm trying t...
Hi I am trying to write a echo program and the USART1 configuration code is shown below. RCC->AHB2ENR |= RCC_AHB2ENR_GPIOAEN; //Enable GPIOA Clock RCC->APB2ENR |= RCC_APB2ENR_USART1EN; //Enable USART1 Clock GPIOA->AFR[1] |= (0b0111 << GPIO_AFRH_A...
I use HAL to go to STOP mode with interrupt (WFI), but the microcontroller immediately exits stop mode.I have LPTIM setup with HAL_LPTIM_Counter_Start_IT() to give interrupt after a few seconds, but even without setting up LPTIM I can't get the micro...
Hi AllI have been experimenting with the Flash write protection most of the day and was hoping to be able to set it by just writing the setting in the FLASH_OPTCR register, however the value that is written doesn't seem to affect anything unless comm...
In Stm32 has too many parameters, So please some explain me how to use this ?. please watch my timer videos. because I know how to use the timer in PIC, but in stm32 which is prescalar and how to calculate for generating pulse(in expected frequency)
