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 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 10:50I am using STM32F205RBT6, Keil 4.73 & Ulink2 & SWD communicationI was trying some test codes for low power mode.One of app note says to configure all inputs pins as analog mode, by first enabling the clock & then after...
Posted on May 27, 2014 at 15:05Hello @all, does anyone know how the following registers behave when the USB peripheral is used in HighSpeed mode(?): - OTG_HS_GRXSTSR/OTG_HS_GRXSTSP : is it required (or even possible) to read/pop a status when DMA tr...
Posted on May 16, 2014 at 13:38Hello, i want to implement the newest version of your SelfTest Lib into our code. But we want to use our current toolchain, a GNU C compiler based cross compiler toolchain GNU-ARM-Eclipse. Is there a documented way to ...
