Posted on May 21, 2014 at 21:43i am using STM32f207i have a flash memory connected to SPI2. I used the ST examples and i got it working, read/write, .. great, ... the problem is the speed ... how fast can i run SPI2? There is a setting SPI_InitStr...
Posted on May 27, 2014 at 19:17Dear all,I have tested the pwm on the STM32F429 EVAL board. It seems all ok.Then I have seen with oscilloscope that with low values of duty cycle from 1% to 20% the pwm works for a while then stops and then restarts.Wi...
Posted on May 25, 2014 at 05:48On the NUCLEO-F401RE, using the STM32F4xx HAL UART driver function HAL_UART_Transmit() to send a sign-on message to the ST-LINK/V2-1 virtual COM port to the host PC, I have noticed the sometimes the full sign-on messag...
Posted on May 27, 2014 at 08:11Hi.I wonder how i can config the STM32L Discovery clock speed from 32 Mhz as it is now down to 25 Mhz. #clock #stm32 #discovery #speed #mhz
Posted on May 26, 2014 at 10:50Hi, I just try to get an STM32F401 running, but it somehow does not seem to work with the standard STM32F4 system-startup files (e. g. from STM32F4 discovery). Is there some comparison PDF about necessary changes when ...
Posted on May 27, 2014 at 13:53I use an STM32F107RC board and use USART2 interface. But USART2 Tx doesn't send first four bytes of each data transaction. I have tried both INTERRUPT and DMA mode.What is the problem? #dma #usart #stm32
Posted on May 27, 2014 at 10:15Is there any example code for implementing DMA on stm32F205rbt6 where I can do rx & tx together.1. I have to send 512 bytes & receive 512 bytes2. After 1 byte tx, wait until one byte received.3. then transmit next byte...
Posted on May 27, 2014 at 18:31We've designed a simple test board for stm32f407 but I am failing to figure out how to activate USB bootloader. I have boot0 pulled high and I have boot1/PB2 pulled down as Pattern1 in AN2606 tells me to do. The diagra...
Posted on May 26, 2014 at 09:18dear all,i am developing the project with the name frequency module, here i am trying to capturing the frequency from 10 hz to 999hz , i am facing some error in the capturing , if i give constant freq it varies with th...
Posted on May 26, 2014 at 16:02Hi there, i'm trying to set up a STM32F429 as a host for mass storage devices. I'm using emblocks IDE with firmware generated by CubeMX (STM32CubeF4). The cube library has an example project for an usb host, which unf...
