XMC4500 Tip of the day: Universal Serial Interface Channel (USIC)

[Travis]

The Universal Serial Interface Channel module (USIC) is a flexible interface module covering several serial communication protocols. A USIC module contains two independent
communication channels named USICx_CH0 and USICx_CH1.

Each USIC channel can be individually configured to match the application needs. The following protocols are supported:
• UART (ASC, asynchronous serial channel)
• LIN Support by hardware (Local Interconnect Network)
• SSC/SPI (synchronous serial channel with or without slave select lines)
• IIC (Inter-IC Bus)
• IIS (infotainment audio bus)

Do you know how to access a second interface from Arduino code?

Serial1 is not being recognized by the compiler (PlatformIO).

Hi Jose,

XMC4500 on board Jlink does not have USB-UART support. XMC4500 relax kit also not listed with ready debugging option in the following table from platform io.

Normally an external USB-UART bridge is used in cases where USB-UART functionality is needed for these devices.

Thanks for the quick reply, @Vasanth

You're right!

We are using an XMC4700 relax kit.

Accessing the first UART interface with Arduino language (Serial) is not a problem, but  does not recognize any other.
