Posted on March 01, 2013 at 04:44Dear, I want to test the systick clock frequency. And use the systick as the RTOS system timer. It would be set to 1ms. And I use the configuration of the demo code as following: if (SysTick_Config(SystemCoreClo...
Posted on March 04, 2013 at 21:06Hi all, I'm using an STM32F4Discovery (it's and STM32F407VGT6 on it).I'm trying to use the TIM4 timer to read a quadratic encoder (plugged on PB6-PB7), but somehow, it doesn't work.I'm using exactly the same code wit...
Posted on March 01, 2013 at 22:32I would like to do a background CRC32 on FLASH such that I do 256 bytes at a time and get a final result. The system must continue to run and meet RT deadlines while the CRC is calculated. Additionally, communicati...

Posted on March 04, 2013 at 03:51It is possible to have two serial outputs under master mode for one SPI? I need to drive two groups of devices at the same time with DIFFERENT data on ONE clock signal. That is, I need and only need one clock signal,...
Posted on February 28, 2013 at 16:54 I have to receive a data on my stm32f100 microcontroller which is sent from a software on PC through RS232 port. I am using IAR C compiler and in the interrupt handler i have some further sensor related progr...
Posted on March 04, 2013 at 11:31 Hi, I am trying to make the I2C work in slave mode in a STM3241G-EVAL. I want to comunicate the stm32f417 with a mother board that is running Linux (that will be the master). I am in the very begining a...
Posted on March 03, 2013 at 11:52hi everyone i am looking forward to purchase evaluation board for learning cortex m4. i would be requiring GLCD/TFT and camera in future for some image processing applications where i might be using DSP capability of...
Posted on March 04, 2013 at 07:45HiRecently I was using my STM32F4 discovery board in my variable speed drive project and got an over-current detection message in the IAR, and LD 7 (Green LED at the bottom of the board) lit up.Now, I think I did not...
Posted on March 02, 2013 at 15:01If I attach cr2032 battery to STM32F103RBT6, how long it can run the rtc and backup the content of ram?
