Another thing people keep suggesting for this is a block GPIO set operation - something that will let you configure multiple GPIOs with a single call. That maps nicely onto hardware which has a single register for multiple GPIOs but there's been abstraction problems implementing it. [unhandled content-type:application/pgp-signature] | |
