Posted on August 27, 2013 at 23:08Hello! I've been wanting to increase the ADC/DAC setup in my design using the STM32F407 chip but I am having a hard time understanding what specific functionality I can use to get more than 2 in / 2 out over a singl...
Posted on August 27, 2013 at 18:46Hi thereAccording to http://www.st.com/st-web-ui/static/active/en/resource/technical/document/user_manual/DM00050135.pdf PF0 is configured as GPIO.I didn't change any solder bridge settings but I cannot get access t...
Posted on August 25, 2013 at 21:51Looks like 168MHz Cortex-M4 was announced two years ago. Have ST announced any faster controllers/discovery boards since?
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...
