Posted on July 31, 2017 at 13:55Hey I use stm32f030p4 and i want counting a external frequency (Learning remote ).I configure timer and interrupts like thisTIM_ICInitStructure.TIM_Channel = TIM_Channel_1;TIM_ICInitStructure.TIM_ICPolarity = TIM_ICP...
Posted on August 01, 2017 at 10:45Hi,I have an 8GB eMMC memory and when I read the capacity I can obtain (2097152*512)/(1024*1024*1024) = 1 GBWhat is the limitation of HAL library about the size of an eMMC ? How I can bypass this issue ?After some ...
Posted on August 01, 2017 at 10:25Hello! I am trying to generate a triangular wave of frequency 8kHz using DAC and DMA. DAC is triggered using a timer so that the DAC speed will be 1 MSPS. I am working on stm32L476 discovery board. I am using stm32C...
Posted on June 07, 2017 at 20:18 Hi guys, I am running into some timing issue using CubeMX, probably after upgrading to the latest version. A couple of weeks ago I noticed my SysTick running roughly twice as fast as expected (half of 1ms) so I ch...
