#125591 - as often as with an UART Responding to: ???'s previous message |
The other thing that I think is goofy with a lot of i2c hardware is that you need to be interrupted way too often.
the IIC I work with interrupt once per byte, I see no way to do less without a DMA (which I have not seen in a '51 ). Erik |
