Question Wii to microcontroller interface

[aurzola]

I want to send Some character data from homebrew app to a microcontroller to display on LCD module. Assuming no wifi. it is posible to use an output port from the wii like one of the gc controllers to read in on the microcontroller?
The usb route is not posible as the microcontroller cannot act as a mass device. Any ideas?

It's possible to use the memory card port SPI, there is documentation for this in wii homebrew. RVLoader uses a bitbanged I2C implementation used in boards like the PMS2 and UAMP2/GBoy audio amp although I'm not sure the documentation is clear on the RVLoader github but you could check.

I'll release some code & maybe write a little bit about wii and i2c after the contest. I use I2C to communicate with my "NPC" [Atmel MCU] controller & make it do stuff. it's crazy how simple it is actually

Wiibrew + microcontrollers sooo cool!
