yep, that's what I thought Another question, regarding write to GPIO output register. I could also measure it but do you happen to know how long does it take to write those 4*2 (8 total) gpio set/clr register? https://github.com/machinekit/machinekit/blob/master/src/hal/drivers/hal_pru_generic/pru_wait.p#L204-L207 >From what I understand from: https://github.com/machinekit/machinekit/blob/master/src/hal/drivers/hal_pru_generic/pru_generic.p#L144-L147 each line "SBBO GState.GPIOn_CLR, State.GPIOn_CLR_ADDR, 0, 8" takes no less than 95-105ns but I don't quite understand the thing that is explained about "Posted Writes": https://github.com/machinekit/machinekit/blob/master/src/hal/drivers/hal_pru_generic/pru_generic.p#L149-L156 Are those 4 SBBO "posted writes" supposedly taking 15ns each? .. or >95-105ns? https://github.com/machinekit/machinekit/blob/master/src/hal/drivers/hal_pru_generic/pru_wait.p#L204-L207 -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
