Whtat are major causes for emi emission. during emi test we are getting spike about 3db at 180Mhz, The product has wifi, sdram, spi flash. the mcu Stm32f446zej has 24Mh crystal and system core clock is 180Mhz.how to use Spread spectrum clock generato...
In AN4566 the maximum sampling rate of the DAC of a STM32F407 is claimed to be 10.5 Msps but I'm not able to get any faster than 7 Msps before it starts to skip samples.The clock of the STM32F407 is set to 168 MHz.TIM8 triggers the DAC via TRGO.DAC1 ...
Hello community,I am trying to use the capture feature on the comparator. I want to use it in low power mode. Right now I have something similar to the logic below:enable capture; //just to say that the capture interrupt is enabled here while(!capt...
Good afternoon,I have a stm32l432kc microcontroller on a custom board with two voltage supplies:1) A LiPo battery where I use a regulator to supply 3.3v to power everything and 2) A coin cell battery to only provide power to the RTC within the micro....
Hi, I have configured two 16-bit general purpose timers in master slave mode and made 32 bit timer to get the time base ranging from micro seconds to minutes. I want to configure two 16-bit LP timers to wake up the system after for specified time ran...
Hi,I am using STM32l072CZYx. I am generating the PWM using timer 3 channel 2. But PWM is getting trigger by SPI, PWM is resetting for some time. When I disabled the SPI, I am getting exact PWM. What will be the reason?What can be done to avoid such...
I have the STMf32f469 board , when I try to send a demo to the board it says that I do not have the St link utility ? Shouldnt I have got that with the StmCube install ? Or do I need to download that specifically ?EDIT> Worked with ST link. Although ...
