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...
I see that times can be initiated by ITR0, ITR1 in CubeMX etc. I understand that it is internal interrupt. I do not how to set for example another timer to turn another timer on and off.I do not see in CubeMX any option to setup one timer as global i...
We have developed our control system around CAN bus 2.0, but we are trying to move up to the H7, and it only has CAN FD. The question is, can CAN bus FD be configured for operating like CAN bus 2.0?
We intend to use STWBC2-HP in our PCB. We would like to use circuit "Qi single coil, fixed frequency full-bridge, USB powered". However, we could not identify components used. Do you have any schematic with higher detail level of details (such as res...
I am writing a code to jump to another application in the flash. In the last step I am initiating peripherals. My question is related if it is sure to de init peripherals without disable the peripheral first. Example: LL_CRC_DeInit(CRC); LL_AHB1_GRP...
Hello,I am trying to do a voltage measurement, i know i can use ADC to do it. What a gpio is capable of when it is configured as Analog Mode? Can it measure voltages? or Can it trigger an interrupt if a defined threshold exceeds?I need a clarificatio...
