Checking the actual pin outputs of the Robostix (R1131) PWM_3 connections, = I find that the labeling of PWM 3A and PWM 3C are reversed. PWM 3A, on my b= oard is connected to the ATMEG pin 7, which is OC3C and the PWM 3C is conn= ected to the ATMEG pin 5, which is OC3A.=0A=0AHas anyone else encountered t= his problem or is this old news?=0A=0AThanks,=0AStephen=0A=0A=0A=0A=0A =0A_= ___________________________________________________________________________= ________=0ADo you Yahoo!?=0AEveryone is raving about the all-new Yahoo!

My silk screen is ok, but I've got R790 so it must have happened recently.

Hi Stephen, On 11/29/06, Stephen Nestinger <ss...@ya...> wrote: > Checking the actual pin outputs of the Robostix (R1131) PWM_3 connections, I find that the labeling of PWM 3A and PWM 3C are reversed. PWM 3A, on my board is connected to the ATMEG pin 7, which is OC3C and the PWM 3C is connected to the ATMEG pin 5, which is OC3A. So I took a look at the layout for 1131 and you're right. I went back and opened up R790 and the silkscreen agrees with the layout, and for some reason the order of these 3 pins got swapped in 1131. Good catch. I'll add an annotation to the Robostix I/O page. -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |
