Why external interrupt shows delay..
I am doing one project with STM32H743ZI.I am using the external interrupt and copy the signal and set the output as input.But is shows about 700us delay.I do not know the reason why its gives such a big delay.

Resolved! How to design UART to achieve a robust communication over longer distances
How should a UART interface be designed so that a robust communication possible can be established between two MCUs. The following table is shown in a data sheet from Texas Instruments. You can see the error rate depending on the baud rate. According...
VREFINT_CAL address for STM32F103T8
Hello All, I want to find the Vref Voltage on which my ADC is operating. For this I am trying to find the VDDA. To get the VDDA I need to find the VREFINT_CAL value of my Microcontroller. I am unable to find the memory address for the same in both da...
