Posted on November 09, 2014 at 23:37I want to use DMA with double buffer. STM32CubeMX provides options for normal and circular buffer. Should I select circular buffer and then modify the source or is it better to wait for the next version of STM32Cu...
Posted on March 11, 2015 at 09:04 I am using microcontroller STM32F On reading EEPROM operation with I2C microcontroller gives 7 clock pulses instead required 9. There is fragment of transmitting on picture. When this cause o...
Posted on August 21, 2013 at 17:05Hello. I have been searching the forums and cannot find an answer, hence I am starting a discussion here. I have been using the STM3220G-EVAL board and the HS USB onboard PHY (obsolete NXP device). I have since crea...
Posted on March 13, 2015 at 16:17Hello, I'm running an STM32L151 at 32MHz and SPI BaudRate = fPCLK / 4. The device is an SPI Master, and tries to read a Slave as fast as possible. I'm using DMA TX and RX to speed up things. I can see the SPI clock r...
