Posted on May 07, 2018 at 09:09I want to implement a low pass filter with cutoff frequency 50 kHz. How do I go about? I have gone through the example. But its not very clear.
Posted on May 06, 2018 at 14:36Hi all.I've run into some problems with the LPTimer and hope that maybe you can point me the right direction so I can find a fix.Some context first:-I have an RTC Alarm interrupt triggering once a second.-Inside the RT...
Posted on May 04, 2018 at 07:47Hi all,I have seven adc channels to convert using STM32F051. I set the ADC to be triggered by timer 15. I also setup DMA to put all the converted results to a memory buffer and have a Transfer complete interrupt set. H...
Posted on May 05, 2018 at 16:50Hi All.I am using STM32F030 as my development platform. I have a RF module connected to UART2.The uart is operating at 9600, UART_RX is configured as interrupt. Things work fine, but sometimes a global buffer defined a...
Posted on October 19, 2017 at 17:30Hi,I have some question about the relationship which is purpose of Initial SP 0x0000 and Reset 0x004 vector and Flash memory address.For example, let's assume that I made one simple firmware and its size is 0x1000...
