I am using the stm32f103 and trying to display a text on a screen via DMA to the USART 2 device. I guess I will turn on the usart2 TX dma (DMAT) request when I need it and turn it off after the current transmission is complete (i.e. in the DMA1_Chann...
as I proposed some time ago, now products->Mikrocontrollers->Resources lists also datasheets. That way, one does not have to check the individual product pages for datasheet updates.Some other proposal however is still pending:List the documents newe...
I've searched through the internet but i'm not able to find any firmware or source for coding the STWBC, atleast a few examples on how to do it. STM provides a binary as firmware to download and use it directly on the evaluation board. But i want to ...
I'm having a problem where I'm controlling 9 LEDs with timers. Whenever I enter stand-by mode, the LEDs turn on/stay on. I want them to turn off. I can shut them down before stand-by mode but as I enter, they turn on. I've tried switching timers in...
Hello,I'm struggling to get the SPI Slave on my STM32F4 running. I send 9 Byte from the master every 1ms with soft NSS: HAL_GPIO_WritePin( MCU_CS_GPIO_Port, MCU_CS_Pin, GPIO_PIN_RESET ); SPISlaveTXdata[0] = frameCounter++; SPISlaveTXdata[1] = sys_g...
hey guys,i'm programming a two motor control system, and must take each of motor current information. (my MCU's ADC setting : DMA, TRGO.)when i get ADC's value using hal libraries, how can i get each of ADC1, ADC2 value???In simple terms : I want...
Hello, I'm developing a custom board based on STM32F072B-DISCOVERY board.I have an external PWM source with variable frequency (from 200Hz to 10Khz), i need to count how many pulses it generates. How can it be done? PS. I've tried with Imput Compare ...
The CR1 register stays 0 (as well as CR2, it looks like all UART2 registers are 0). My first thought was that the Bus is not enabled - as UART1 is on APB2 and UART 2 and 3 are on APB1 , but I enable UART2 bus - this is the enable code : /* Enable G...
I have a new product using the stm32l486, and the GPIOG pins mentioned in the title do not appear to work as outputs, even though they are configured identically to the GPIO pins I am using for ports A-F. I cannot find anything in either the datashe...
Hi, I have STM32F407VE and this display which require 5V power:Is it ok, to connect it to 5V and to FSMC pins? I wont demage FSMC pins?
