UART Communication Using DMA Not WorkingI have Nucleo-F767ZI Rev B board and using the STM32CubeIDE Version: 1.1.0.To test and implement UAR-DMA communication as presented in:STM32CubeMX basics: 10.11 STM32Cube HAL labs UART - UART DMA https://www.yo...
Hello,I am currently working on a project which requires the use of the transmission / reception of a UART by DMA. I would like to make two transmissions in a row like the following.void send_all_registers() { HAL_UART_Transmit_DMA(&huart2, (unsigne...
Hi,I am pretty new to programming STM32 MCUs and I have been having a hard time finding out how to change the SPI prescaler value on my Nucleo-L476RG board. I am trying to implement FatFS using SPI via an online tutorial and their method of changing ...
STM32G474RE: I need to reset the USART3 peripheral and I see the register RCC_APB1RSTR1.USART3RST. I assume this bit needs to be set, then cleared, after a delay. But there doesn't seem to be documentation. What is the correct procedure and how long ...
Hi,So I have two layer board. I have SDIO connected to SD Card and another SPI to LCD. My board uses DC-DC (Recom 3.3V) for digital power and LD1117-3.3V for analog power and both with common ground plane. No digital lines cross analog lines. Actuall...
I am making temperature data logger using STM32L071, so every week I have to create (non editable) a PDF report from the device. Due to regulation and data protection I can't create this is PC/ Laptop. So only option left is generating pdf report ...
Hello,we are using various STM32F103 derivatives in several products. So far, we never had any problems reading out the flash memory size from the factory-programmed register at 0x1FFFF7E0.Currently, we are using the STM32F103R4 device (photo attache...
I wrote this code to initialize ADC1. What Im trying to do is take input from a Joystick and map it accordingly and send a corresponding PWM output to a LED. RCC->CFGR |= RCC_CFGR2_ADCPRE12_DIV2; RCC->AHBENR |= RCC_AHBENR_ADC12EN; ...
I am working with a STM32L552ze on a nucleo-144 board and hoping to get to the lowest power consumption available for this processor. However currently I am at 450uA on the MCU power pin. When i first started i was at about .181uA. This is with the s...
