STM32L151's AHB is at 32Mhz and APB runs at 16MHz.Given in the datasheet that SPI Slave clock can be APB clock/2 max.I have tried to transmit 7 bytes of data from STM32L151. I am able to receive data properly if my SPI master clock is configured to 2...
Posted on March 17, 2018 at 16:25I am setting up a board that uses an STM32F103C8. It has an LED on PC13. I am running FreeRTOS and configuring with STMCubeMX. I am also enabling the LSE clock and RTC.Using Cube MX I configure this and ensure that T...
I am working with a STM32L0538 discovery board and am ready to move to my own target board. According to the documentation I can use the STLink/V2-1 portion of the discovery board as the debugging interface for my target board using the CN5 connector...
Hi,I use ST-Link/V2 programmer. I connect my stm32f407 with this circuit to my programmer.Everything works OK.I tend to connect my JTAG connector to SWD pins in my board But when I disconnect Reset or VCC pins from my programmer ( while my board is p...
Hi, i'm using SPI to communicate two STM32F446REUnfortunately, I get different value after the reset button pressed. Due to some other reasons, these two 446RE use LL and opencm3, but I don't think it is an issue. The code for master in one of the ...
The DCMI controller in STM32H7 is faster than F4 and F7. It supports a pixel clock up to 80Mhz. However, is the FMC controller fast enough to acquire such fast data? Let's say, one has an image sensor that generates 10-bits or 12-bits data with 74.25...
Posted on January 28, 2016 at 20:57The STM32Cube does not generate some .c and .h files for my code.I'm using MDK-ARM V5 toolchain for my project.Whenever I try to create another project the missing files change in random fashion, sometimes its mxco...
Hi all - I'm beginning a project that will utilize the STM32L496ZGT6. It's been several years since I've worked in the STM world, so my knowledge of available software is quite dated. I'd like to hear any feedback on the following:I want to use an OS...
Posted on May 31, 2018 at 17:53I've been going through numerous old posts that ask similar questions however I'm seeing something slightly different then everyone else.I've written bootloaders before for Kinetis MCU's which I had hoped to essentiall...
After upload my program into a stm32F103C8T6, the program doesn't start. I just use STM32CUBE-MX to configure my mcu, and I just add some blinking on 5 output (push/pull). But after reset my output seems to stay in high inpedance ? Does Mcu start its...
