Hi all, I am now working with STM32F205 ADC1 w/ code generated by STM32CubeMX. I find that ADC pin has a 0.5V output even it is unconnected (floating). I tried pin PC0 (channel 10) and PC1 (channel 11) one by one and both have the same problem. Afte...
I dont know how to calibrate rtc by temperature, i confused. When I look at RTC smooth calibration method like this, I thouht that i understand. After that i encountered AN2604 application note and i confused again.I cannot understand 2nd section in ...
Am using STM32F407VG -TX/DISC1
I was wondering.What will happen when changing/writing data of the memory you assigned as buffer for DMA in circular mode. Will it be ok, garbage? Is there maybe a shadow register?Is this for every mem-to-peripheral interface the same?I'm very curiou...
What do I need to do to be able to be able to set the time through the use of a push button. Is there a way to set the hours and min separately or does the RTC need to be set all at once? Here is my call back function where I am trying to set just th...
i am using stm32h723zg nucleo board, I'm using adc's direct channe, h723zg have only PC2_C,PC3_C,.Firs ı use this function and no noise>LL_SYSCFG_CloseAnalogSwitch(LL_SYSCFG_ANALOG_SWITCH_PC2|LL_SYSCFG_ANALOG_SWITCH_PC3);second ı use this function ...
Hello!I have a 100 kHz external singal connected to a GPIO input (PD7), at the moment I am generating the signal with a good signal generator so it has very little jitter. What I want to do is measure the length of the period of each one of 4096 succ...
Hello,I am working on Nucleo-H745ZIQ board. My cortex M7 running on 400MHZ and My Cortex M4 work on 200MHZ. I am interfacing the ADS7046 for that I need 450ns delay for conversion. The systick generate delay in millisecond. How I create delay in nano...
I need some clarification on using the Uart device in DMA modehow should i handle the overrun condition (ORE bit set in SR register) ?The read sequence SR and DR register reset the ORE bitIn DMA mode how I can do this ? I must enable the EIE bit in C...
I have tried turning these pins to GPIO's and tried toggling them, however, they seem to just be floating. I can confirm that these pins have been soldered on properly, since I have checked them using an X-RAY inspection system. I can also confirm th...
