I don't think I've ever run more than 5 or 6 devices on an I2C bus without running into rise time, bus contention, or address collision issues. Some devices scoop tons of addresses, and most only allow re-assignment to a few alternate addresses. I agree it's still lower pin count than SPI, but realistically you don't get anywhere near 127 devices. |
