Posted on May 16, 2013 at 23:25Hi, i'm reading the sensors on my STM32F3-discovery, and i've found out the reading arequite ''jumpy''. That means gyro and magnetometer value have consistent change (>1024) aven when the board is static. notice that a...
Posted on August 24, 2013 at 06:37I'm trying to interface an old computer with a VME interface which can (and does) produce a burst-y 20MBytes/sec throughput. There's a CPLD to decode the VME timings, and I'm intending to use the USB as bulk-data tr...
Posted on August 16, 2013 at 17:23Hi there, I am new to STemWin, have a question about using Memory devices. I observe some strange behaviour of window appearance using memdev and reproduced it in short piece of code, could you please explain. Backg...

Posted on August 26, 2013 at 15:47Hi thereI'm still a bit confused about whether I have to connect the nRESET pin of the 10-pin Cortex Debug Connector to the NRST or the NJTRST pin of the STM32 in case of both JTAG and SWD connection. Could anyone t...
Posted on August 15, 2013 at 05:55Hello: Today , I want to capture the high-level length of input signal using TIM5 Channel 1 (PA.0) in chip (STM32F103ZET6)?but why program can not enter TIM5 interrupt service ? please help me ! I have attached ...
Posted on August 26, 2013 at 15:20 Hi , I am having a little bit of trouble configuring the audio codec (cirrus CS42L52) on the MCBSTM32F400 (stm32f407IG) evaluation board . I am trying to do a reset to the codec via the reset pin , but looking fro...
Posted on August 22, 2013 at 16:35Hello Everyone, I am using stm32f407 which is interfaced with 1MB of external RAM. Linker script is a simple one where it puts the data and bss section in external RAM. Regarding code execution I don;t have an issue...
Posted on August 25, 2013 at 14:46I'm new on STM32F407 and STM32F4xx DSP and Standard Peripherals Library. And now I've got some question.1) GPIO timingWhen I code GPIOF->BSRRH = 0x0100U; GPIOF->BSRRL = 0x0100U; GPIO...
Posted on August 24, 2013 at 18:41Hi there, If I setup both ADC1 and ADC2 in independent mode and set ADC1 to scan channels 1,2,3 using DMA and setup ADC2 for analog watchdog on channel 2 having different sampling times for channel 2 between the ...
