#101102 - All IO used. Responding to: ???'s previous message |
I am trying to keep the costs down and would prefer not to have to add an expansion port (or a bigger microcontroller).
Would the shared clock idea work? I can't see any issues with it. but there is no harm in being second guessed. Thanks Marshall |

Thanks for the link | 01/01/70 00:00 | |
Because LPC has hardware IIC built in | 01/01/70 00:00 | |
I am not too worried baout the IIC, but | 01/01/70 00:00 | |
Reconfiguring the port to IO after start | 01/01/70 00:00 | |
but it will still toggle when configured | 01/01/70 00:00 | |
Why does the SPI care | 01/01/70 00:00 | |
yes, but![]() | 01/01/70 00:00 |
