Posted on May 12, 2015 at 11:01 Hello, I am working on simple project, where i need to exchange data with other microcontroller, but it would be better to use DMA for it in circular mode. I had this program working without a glitch on STM32F...
Posted on May 12, 2015 at 01:06Is there any clear recommendation from STM how should the firmware configure unused untied GPIOs? In past STM32F1 controllers we used to configure them as output '0' in order to avoid noise (our environment is very noi...
Posted on May 11, 2015 at 18:14Hi All,I'm studying STM32F3 Low power modes and I need to go in standby mode periodically and wake-up via RTC after n seconds (Run->standby->Run ...).I set the RTC, the wakeup-Timer-IT, I do something in main loop and ...
Posted on May 04, 2015 at 18:49Hi I am using discovery board with stm32f429. I configured well the ADC for DMA and works fine but I don't know what is the sampling rate. Anyone can explain how to calculate it? The clock is at 90Mhz the prescaler is ...
Posted on May 09, 2015 at 20:23I finally got the STM32Cube generated code for USB CDC on the STM32F4Discovery working. I had three issues that need to be corrected with in the generated code. I'm using STM32CubeMX ver 4.0.0 with STM32Cube V1.0 and l...
Posted on July 18, 2013 at 15:47 Hi, I have a problem where I cannot get a higher priority interrupt to interrupt a lower priority one. My understanding is that this should 'just work' so I'd really appreciate your input on this... I've creat...
Posted on May 10, 2015 at 15:40 I managed to send via stm32f4 data using usb and vcp.What i am trying to do now is to read data from pc .In order to check what is read through usb i send it again to the pc. My problem is that the board seems ...

Posted on May 08, 2015 at 22:03Hello,I have trouble to communicate with a BlueNRG device. I�ve tracked it down to my SPI implementation. Assumed I want to have a �usual�, full duplex SPI master interface on a STM32L152, using CMSIS I initialize the ...
