MCU Serial Bus Sharing
Discussions focus on sharing I2C, SPI, UART, and PWM peripherals across multiple microcontrollers and even Intel chips, including challenges with voltage levels, optoisolators, level converters, pinouts, and protocol comparisons like I2C vs SPI.

Wouldn't a bunch of logic level converters resolve that?
I2C perhaps? Fewer wires than SPI.
Would be surprised if they didn't have optoisolators to cater for that scenario
The peripherals are all i2c, pwm, spi or uart? So they are shared between all microcontrollers and even intel.
The irony of an 8-bit wide serial bus.... %-#
It's sad that a 5 volt powered device can't natively talk to the entire world of 5 volt logic peripherals.
Wouldn't you have to at least wire the chip select pins somewhere distinct for that to work? I know little about electronics.
You'd need opto-isolated data lines. I can't see any common devices having that.
Interesting, is the pullup resistor common for other protocols like SPI?
Which is kind of sad, since the Uno pinout is horrible for high-speed signals
