The web page about the Conect-ME 9210 describes the FIM as a way of getting any kind of communication interface (CAN, USB, 1-Wire) on the module. However, what are the actual hardware interfaces in the Connect-ME? UART, I2C and SPI? I guess that any other interface could be used through SPI and external circuitry…
Thanks in advance,
>what are the actual hardware interfaces in the Connect-ME?
The hardware interface is always just GPIO/functional pins. FIM is a programmable peripheral that when used with supplied microcode can function as UART, CAN, USB, 1-wire… Those pins that are attached to this FIM now function as your new HW interface.
and… as far as I understand, only the UART microcode is supplied with the Linux dev kit ??
That is correct. Additional functionality will be delivered with upcoming DEL updates, such as CAN bus and USB device low-speed.
