The data is scattered everywhere and for a newbee it is very hard for them to find the infomation they need. I think they have a higher priority by completing the next "stable release" in mid Oct. </p> http://forums.leaflabs.com/topic.php?id=233#post-1716 Fri, 08 Oct 2010 15:06:45 +0000 crenn 1716@http://forums.leaflabs.com/ <p>Because that's 1.125MHz </p> http://forums.leaflabs.com/topic.php?id=233#post-1713 Fri, 08 Oct 2010 15:03:44 +0000 josheeg 1713@http://forums.leaflabs.com/ <p>72 mhz sorry GPIO humm I am looking <a href="http://leaflabs.com/docs/maple/gpio/" rel="nofollow">http://leaflabs.com/docs/maple/gpio/</a><br /> where did you find that?</p> <p>I see the SPI section has :<br /> SPI_18MHZ<br /> SPI_9MHZ<br /> SPI_4_5MHZ<br /> SPI_2_25MHZ<br /> SPI_1_125MHZ<br /> SPI_562_500KHZ<br /> SPI_281_250KHZ<br /> SPI_140_625KHZ </p> <p>this line looks strange how could it be faster than the clk?<br /> SPI_1_125MHZ </p> <p>referencing:<br /> <a href="http://leaflabs.com/docs/maple/spi/" rel="nofollow">http://leaflabs.com/docs/maple/spi/</a> </p> http://forums.leaflabs.com/topic.php?id=233#post-1710 Fri, 08 Oct 2010 08:45:30 +0000 leaflabsandy 1710@http://forums.leaflabs.com/ <p>Max clock is 72 MHZ (not 75MHz) but GPIOs toggle at up to 18MHz - see Maple's docs. </p> http://forums.leaflabs.com/topic.php?id=233#post-1709 Fri, 08 Oct 2010 08:41:34 +0000 josheeg 1709@http://forums.leaflabs.com/ <p>maple at 75 mhz how much time does toggling a pin take? working with sensors their is a window of time for me to respond it must be x long but not y it is too long. </p>
