UART0, UART1 and I2C0 utilization and Initialization

[mexco]

Hi, I need to use UART0, UART1 and I2C0 in my application. I initialized these in overlay file (attached). When, debug is run, it is observed that the I2C binding is not successful see attached image file. I am using UART0 and UART1 in asynchrounous mode.  The zypher.dts fie also is attached.

Hi

You should be able to do enable multiple peripherals with the same ID and switch between them in your code.

On how to do this, see nRF5340 Documentation on Peripherals with shared ID and the Peripheral Resource Sharing (PRS).

Is this what you were looking for?

Hello, I studied about Peripheral Resource Sharing. I could not find method to switch shared resources between competetive peripherals alernatively. UART1 and I2C0 share same address space and only one should be enabled at a time. Did, you find any ways to multiplex such pripherals ? I need to send the data to UART1 and to I2C0 alternatively and never need both at time. What is metod to use these alteranatively ?

Hi

Have you tried to disable UART1 in software when using I2C0?
