hello everyone !i'm using a nucleo board (NUCLEO-F401RE) to program a MCU STM32F301 placed on newly fabricated pcb; the mcu has never been programmed.i have disconnected the jumpers to use the CN4 connector. i have just connected the SWCLK (clock sig...
i have interfaced opt8320 optical sensor to stm32f446zet.I hav configured STM as master and Opt8320 as Slave. Can i initiate continuous registers read from sensor using I2c ?Please share suggestions regarding this issue.
I am more of a assembly guy. So I have problem in understanding the functionality of I2C control registers. It would be helpful if you could provide an outline or a pseudocode as how to write to a register or how to read from a register ? How to writ...
