The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on October 09, 2017 at 11:04Hi,I am using SPI1 peripheral as master at 16 MHz on STM32L443, I can send and receive data correctly using DMA.My application requires to speed down SPI to 1MHz during a moment so I changed SPI baud rate on the fl...
Posted on October 07, 2017 at 07:41Is there a utility program available that enables one to create custom screens for the STM32L053 Discover Board? I've looked at a couple of demo programs for the E-Paper display and see that the graphics elements a...
Posted on October 09, 2017 at 11:42Hello,for all families beside F1, the cubemx/mcu/IP/GPIO-STM32Xxxx_gpio_v1_0_Modes.xml give a complete list of the available device functions on a pin. For F1 files, only functions available on a pin that may get r...

Posted on December 26, 2016 at 10:31 Hi all; I try to send by CAN bus to 4 individual motor controllers their pwm speed settings in one go. I found out however, that the first three messages go through perfectly, but the forth message got stuck. ...
Posted on January 27, 2017 at 20:06I have been thrust into a situation where I realize I am in over my head. Eventually I think I will figure it out but could use a leg up with this STM32F437 device. I know little about it and especially it’s dma.Th...
Posted on October 03, 2017 at 20:25Hello, fellow developersI am using STM32F4 Discovery board with OV9655 camera module. I use the sample codes given and everything works all right. Right now, I am going to tune the qualities of the camera images, s...
Posted on October 06, 2017 at 06:57Hello,When I enable PCROP for an area of Flash by Option byte, Debugger does not work.It seems that Debugger has hanged up.I use IAR EWARM as IDE.Is it PCROP's specification that Debug is NOT possible when PCROP is...
Posted on October 05, 2017 at 15:38Hi all,I am using STM32F407VET6 with 25MHz crystal by STM32Cube_FW_F4_V1.16. I have changed HSE_VALUE to 25000000 in system_stm32f4xx.c and RCC_OscInitStruct.PLL.PLLM = 25 in SystemClock_Config main.c, but I found ...
Posted on September 26, 2017 at 13:32Hi. Can someone please help me see where I am going wrong? The program will transmit the UART message but crashes when it gets to the 'HAL_UART_Receive' function. I am using the STM32F746 Discovery Board.UART_Han...
