What is connected to the ''internal wakeup line''
Posted on February 02, 2017 at 10:59Hello,reference manuals for the L4 series in the power section talk about a EIWUL bit in the PWR->CR3 register, enabling an 'internal wakeup line'. A search in the manuals and with google does not bring up any fur...
Resolved! Problems saving variables to FLASH in STM32G030F6P6
I've just bought a STM32G030F6P6 dev board and I'm testing its cababilities.And one thing I'm having problems with is saving my data to the FLASH.The first time it writes as espected in the FLASH, but not in the second, HAL_FLASH_Program returns HAL_...
STM32H743 Can BDMA trigger a DMA2 transfer
I already set up a SPI1 Tx and Rx with MDMA and DMA2 moving data from DTCMRAM to RAMD2 to SPI1Is it possible to do the same with SPI6 ?I see that DMA2 can access APB4 peripherals (including SPI6) but "sp6_rx_dma" and "spi6_tx_dma" hardware requests a...
Resolved! STM32H757 Eval Board locked in illegal power configuration. How to unlock ?
Hi, I dont know how this happened, but my Eval board STM32H757 can not go after :SystemClock_Config() ==> HAL_PWREx_ConfigSupply() ==> while (__HAL_PWR_GET_FLAG (PWR_FLAG_ACTVOSRDY) == 0U)The progam stay in the while loop : while (__HAL_PWR_GET_FLAG ...
Resolved! I want to send 16-bit numeric 16-channel data measured by ADC with BLE. However, when programming according to the BLE example, the transmitted data is in the form of 8 bits. What is the general way to solve this?
I want to send 16-bit, 16-channel data measured by ADC. but I realize BLE is transfering 8bit data. How can I solve this?my key script is below.<main.c>uint16_t DMAo[16]; HAL_ADCEx_Calibration_Start(&hadc1, ADC_SINGLE_ENDED); HAL_ADC_Start_DMA(&hadc...
How to reduce the power consumption of a Nucleo board? (Nucleo-STM32H7A3)
I am producing a prototype and will not be making a custom PCB therefore I need to try to reduce power consumption of a Nucleo-STM32H7A3 development board.With the microcontroller in standby mode (approx. 3uA) the dev board itself consumes 6mA runnin...
will B-L475E-IOT01A board supports FFT commands like converting time dominie to frequency dominie.
I am trying to convert time dominie to frequency dominie to calculate FFT of that data. If so, who can I do that.
STM32L4P5CET ADC freezes at high noise environment
I'm using an STM32L4 for a solar inverter control project to control some H-bridges and sense some voltage and current. I run into this particular issue that when the environment is noisy (the DC input to the H-bridge is high), the ADC sometimes will...
