Hi,I am reading a burst of data 3072 half words from slave SPI device.The Slave device requires NSS to be released after each half word transmission.When I loop on HAL_SPI_TransmitReceive() function with size =1 for 3072 times it's OK.but when I try ...
The MCU I'm trying to use in my application project is the STM32F446ZCJ. The main purpose is to generate 48 PWM to control the regulators. Is it possible?
STM32F746/AtollicI want to receive periodically a certain number of bytes from an ADC via SPI using DMA.Since there is no Tx line, I thought it would be correct to set the SPI at SPI_DIRECTION_2LINES_RXONLY and to program a DMA for Rx. I called this ...
Hi,Anyone know what's this for? I got a Keil project and use Cube made a TrueSTUDIO project and then copy all of source file from original Keil project.Seems functional and print out some message to console at the end got this message.rst:0x1 (POWERO...
Hi,I am using STM32F051 controller. I have done UART initialization coding but I am not getting interrupt for it. Is there any problem with alternate function register configuration. I am using Pin PB6 and PB7 for Uart. Also I tried finding example c...
I want to run the application code other than the default location of flash 0x08000000 in STM32 MCU.For doing this I have modified the VECT_TAB_OFFSET = 0x200 in system_stm32l4xx.cSCB->VTOR = FLASH_BASE | VECT_TAB_OFFSET; Also, FLASH (rx) : ORIGIN ...
Posted on April 10, 2017 at 09:56Hello,I have a board with the STM32L476RET6, the shutdown mode worked a time and now it resets just after the STM32 enters in shutdown mode. I tried the same program with another same board and the problem does not a...
In some of the tutorial materials it mentions that the ADCs on the STM32F7 devices can be used in single-ended or differential input modes. I have studied the reference manual but have had no luck in defining how to use the STM32F767's ADC in differe...
I have a problem with a hardfault in my system that I cannot resolve. The problem occurred while operating the display. When I change the transparency value, hardfaults suddenly occur (BSP_LCD_SetTransparency). But elsewhere in the program.Now I have...
Hello All,I want to make STM32L071 work in I2C slave mode, is there any reference manual or sample code available to understand to program STM as in slave mode.Found some documents but not much details available.
