I have uint16_t array[2000];HAL_ADC_Start_DMA(&hadc1, (uint32_t*)array, 2000);I get values from 0 up to 65535but when I declareuint8_t array[2000];I get values 0-255I shouldn't be bigger than 4095 since it is 12 bit resolution for ADCI have STM32L416...
Posted on June 20, 2018 at 15:33Hi All,I'm developing an application using CubeMx to generate the basic code. On CuebMx I enabled freeRTOS and LWIP.Now I would like debug my threads but Eclipse gives me access only on the thread in esecution before ...
The SDRAM HAL module has DMA functions but there is no tab in CubeMX to set up a mem2mem DMA channel. This is with CubemX 4.27.0. Is the DMA a pre-requisite for LTDC operation or does it use it's own internal memory access.
Posted on August 11, 2017 at 05:02Hello, I am using an Olimex-E407 board to measure some signals (AC signals). After some reading on ADCs I learned that there are a few error that have to be taken into consideration when doing measurements and some ...
Hi,I've been playing around and refactoring a small test app for the STM32F769 DISCO board. The app runs fine and I retest after even the smallest code tweak.What I'm seeing is that physical position of the function SysTick_Handler within the source ...
I've been trying to adapt an example piece of code that utilizes a UART from the Visual GDB website. The adaptations are:Using an STM32F769 Discovery board.Communicate with an ESP8266 device plugged into the board's WiFi socket.I managed to work out ...

Hello,I am a student of electrical engineering and I'm now starting a project where I need to use the stm32 architecture.The idea is to use a NUCLEO-H743ZI board and to connect 8bits of the GPIO to a VGA Cable and display a 640x480 60Hz 256 colors i...
Hello,I have been working with the STM32H7 and I have been implementing the Protected Area for saving memory in the sector 1 (128KB) shared with my boot loader and the application.I have experienced two different issues with this H7 processor:When I ...
stm32l452, uart. CR1_TE is = 1, now I set CR1_TXEIE = 1. Is ISR-TXE = 1 (and INT generated) now too? Or really only if 'data is transferred to the shift register' ?
