Posted on May 14, 2015 at 22:02 I am reading data from a ds 1621 on stm32f4 using i2c 1 on pb6 and pb7. Data sent by the device is fragmented into 2 bytes according to datasheet.I tried to read the first byte.It worked great.Then i decided to...
Posted on May 14, 2015 at 10:18Hi. I'm quite new into the STM32 devices, so apologies in advance for the scrappy code! I've got a STM32F429 Discovery board attached to a SSD1963 display though the FMC (8 bit mode at the moment), however I cant seem ...

Posted on January 17, 2015 at 22:16Hello, I have a STM32F4 Discovery board, which I plan to use as sensor-based data acquisition board, switching from RS232 to USB communication with host. The simplest path I see to take is to make the device a Virt...

Posted on May 13, 2015 at 10:45 Hi All, I've been working my way through all the retarget.c threads on here and Keil.com today, trying to resolve the old Symbol __stdout multiply defined (by stdio_streams.o and retarget.o) Symbol __stdin multiply de...
Posted on May 13, 2015 at 16:36Hi I connected audio to ADC and can DSP with success only if the audio is from speaker out. I need to connect audio from a device which outputs 500mvpp. I am using the follow input circuit http://www.frinos.com/adc.png...
