Are the low pins set as input or output? Are the pull-ups turned on? WHICH pins are they, because there might be an alternate function turned on. Jim On Sep 29, 2009, at 5:44 PM, blue_eagle74 wrote: > That is my question. They are set as inputs with pullups enabled (I > think). h

the inputs are labeled in my code and the pullups are also, I think. The only alt function is the TCCR0A. Brian --- In AVR-Chat@yahoogroups.com, Jim Wagner wrote: > > Are the low pins set as input or output? Are the pull-ups turned on? > WHICH pins are they, because there might b

It does not need to be exactly at "logic 1". Generally with AVRs, inputs recognize as logic one is anything that is above 0.6*Vcc (I think, check the spec sheet). Jim On Sep 29, 2009, at 4:20 PM, blue_eagle74 wrote: > I am trying to use internal pullups on the tiny2313 but only 2

That is my question. They are set as inputs with pullups enabled (I think). here is a short video of what I have done. one of the switches has a pullup and the start button (not installed in this video) has a pullup working, that is it. Brian > > What are the pins at 0V? > > Mark

I am trying to use internal pullups on the tiny2313 but only 2 pins are actually at a logic one. The are going to a pushbutton switch for each of them. I have checked that the switches are open also. I set DDRx to 0x00 and PORTx to 0xFF. I even tryed to set the PUD in the MCUCR t

I'm curious just how they're tested, and is every unit tested before it goes out? I have never heard of that happening either. Zack On Wed, Sep 23, 2009 at 9:15 AM, Tim Mitchell wrote: > > > ----Original Message---- > From: AVR-Chat@yahoogroups.com > [mailto:AVR-Chat@yahoogroups.

It obviously sounds like they were never programmed in the first place. Maybe they slipped through. Is there any E^2 or RTC that was supposed to be programmed too? Is that there? Roland 2009/9/23 Tim Mitchell > > > ----Original Message---- > From: AVR-Chat@yahoogroups.com > [mail

Strange one... We designed a board using a Mega128 which has been assembled, programmed and tested in a small batch by an assembly company. The programming was done using an AVR-ISP mk2. The customer has returned several of the boards because they don't work. On checking it seems

You still have to set DDR as an output on that pin, *then* the USART will override the Port/PIN I/O functions with Tx/Out. All pins default to inputs at reset so that the part does note have a "Lets Light Up the World" attitude like the old 6820 did. On Sat, Sep 12, 2009 at 5:52
