Posted on March 07, 2012 at 08:29I tried wave playout using the normal mode i.e. through Flash memory and the AUDIO_MAL_MODE_NORMAL, this worked fine. However when I try playout via uSDCard I find that the output is very noisy and defnitely corrupt...
Posted on March 06, 2012 at 05:20I'm trying to implement USB device that emulates mass storage on USB FS, however, the data source is approx. 10 times slower than USB FS transmit rate.I tried to wait in Mass Storage read callback for data, but it ...
Posted on March 02, 2012 at 21:28Hi, I am trying to update the fash of STM32F407 by using the Flash Loader Demo V1.3, but it does not seem to communicate to my processor. I used this program to flash my STM32F10x series, but I don't know if it will ...
Posted on March 06, 2012 at 23:49Hello, We'd like to program debug on TWO STM32 Cortex M3 CPUS with a Keil ulink Pro with Samtec FTSH-110-01 Cortex Debug+ETM Connector. We only found how to daisy chain the JTAG but not the ETM trace. Suggestions ple...
Posted on March 06, 2012 at 16:08I must be blind and stupid but I can not find the usb library or any device example code on the ST website. There is the host fw update demo yes, but no device mode examples? And the usb library is updated march 2011...
Posted on February 29, 2012 at 13:22Hi, I'm almost done finishing my STM32F4 Eval Board. But I still have a few questions: I want to use the internal regulator so I connected Vcap1 and Vcap2 with cap's. There is still this PDR_ON Pin. should i leave...
Posted on March 02, 2012 at 11:49Hello. I'm trying to connect two stm32f4discovery boards through I2C. One will be the master receiver, and will ask for 4 bytes of data to the other (slave receiver). I found an example for the master receiver, and i...
