I²C link between ST7FOX and STM32
2009-12-17 10:58 PM
I am on a project in wich I plan to use 4 ST7FOX to manage I/O and a STM32 to make calculations and link with a host.
I plan to dial in I²C between the 4 ST7FOX and the STM32 using 4 ports as ''chip select''. My problem is that the ST7FOX are supplied with 5V and the STM32 with 3,3V. Do somebody have already experimented such a configuration? ANy advise or solution is welcome! Regards whitebull
