Posted on March 03, 2016 at 15:36 Hello ST-community, I am able to setup my external SRAM and access and test (memtest) its memory regions. It works! However, I do not know if my configurations are correct. It is hard for me to und...
Posted on February 25, 2016 at 16:07Hi, I'm quite confused about 5V-tolerant input pins of STM32F405. Referring to the manual, the picture ''Basic structure of a five-volt tolerant I/O port bit'' shows diodes that protect the port. In this configura...
Posted on March 03, 2016 at 10:14Hello, I have been designing a controller for an interleaved power converter using the STM32F746 Discovery board. Since I need to have four pulses with different duty cycles and phase delays (which will be variable),...
Posted on March 02, 2016 at 12:11Hello, I'm using the internal EEPROM on a brand new STM32L021. In order to save some data into that EEPROM in an ''asynchronous'' way, I use DMA1 channel 1 in MEM2MEM configuration. My issue is that as soon as DMA_CC...
Posted on March 01, 2016 at 12:11Hi all,Trying to implement a basic external interruption on the stm32f407 discovery board, the microcontroller allways freeze after receiving external interrupt. After some test i discover interrupt cause a call to t...
Posted on March 02, 2016 at 18:12Folks, The 64 pin package of the STM32F103 has no Vref pins. I can't see any way, though, of switching between external and internal ref for *any* of the parts. I'm assuming that where there is no Vref pin, you can ...
Posted on July 02, 2014 at 15:16Hello, Please could someone post the details to manage the SPI NSS signal? The master drives it ''manually'' using a GPIO bit. I want to use the SPI as a full-duplex master (sending and receiving data simultaneously)....
Posted on February 29, 2016 at 15:57Hi, What is the maximum frequency of STM32F030F4P6 at 2,5V ?Does the supply voltage have an impact on choice of capacitor value ?I'm planning to use 20pf capacitors and 8 mhz crystal On the STM32F0 discovery schem...
Posted on March 02, 2016 at 11:48Hi All,has anyone installed a linux,like, OS on the board ?Thanks
Posted on March 01, 2016 at 16:52 DAC is used for generating sinus wave 1kHz. 1000 sample is over DMA transferred on DAC 1MHz/1000SPS = 1kHz It would be good to start each sinusoid nullify one of the counters. This signal, after passing through som...
