Posted on May 14, 2013 at 23:40I am trying to use GPIO Pin PE9 and PE10 as outputs to a system. From using the STM32L1Discovery Board I know that the GPIO Output voltage should be 3 V. But when I am using the F4 BOard my output on PE9 is 2 V and P...

Posted on May 13, 2013 at 11:10Hi guys, i've a problem with USART communication using interrupts.Using only USART device, the communication works correctly.When i try to using the usart device with some other timers interrupt routines with timers ab...
Posted on May 13, 2013 at 20:56Hi, in STM32F4 RM 26.3.12 it says, that ''USART supports only bit rates up to 115.2kBps for the SIR ENDEC''. Can anyone tell me the reason? (115.2kBd must be an increibly low data rate for a 168MHz processor). In fact ...
Posted on May 13, 2013 at 00:12I am successfully using I2C control and I2S to send data to the CS43L22 and producing simple sawtooth--> musical notes(see http://www.mind-dump.net/configuring-the-stm32f4-discovery-for-audio#comment-1344). When I try ...
Posted on May 04, 2013 at 06:01I am trying to implement at FAT FS on the STM32F4 Discovery board...the firmware package provided by st supplies third party files. But are these files enough to implement the FAT FS on the STM32F4 board? Or is there ...
Posted on February 13, 2013 at 10:52 Hello, i am having trouble writing code on STM32F4Discovery. my goal is to get values from ADC in continuous mode and send them to USART/UART (with DMA or without)using interrupts. so i wrote a code made out ...
Posted on May 13, 2013 at 15:46 Hello, I have a problem with external interrupts on STM32F4Discovery triggered via push-button. The button is connected to pin PA4 using the same technique used for USER button (the picture is from the user manual):...
