Posted on April 28, 2013 at 09:27I configured ADC1 and ADC2 on fast interleaved mode and use DMA for ADC data transfer. I expect that when I call the StartConversion function of ADC1, the ADC2 should be started automatically by ADC1 after 7 ADC cloc...
Posted on April 27, 2013 at 00:26HiI find problems with capateur internal temperature sensor STM32F4 Discovery, I have measured as false (-80.50...-45.00...-60.50 ).I know if my code is wrong or the formula that calculates the temperature.I hope the...
Posted on April 26, 2013 at 18:25HI, I want to know how to convert the values ​​that provides MEMS accelerometer on g because I need to set the threshold for single /double click detect.For example in the program MEMS in STM32F4-Discovery_FW_V...
