Re: Gertboard Connection to Pi (cable twist)

I agree with sylverfox.. You could keep the connector the way it is, but use a RasPi stacking header. That way, you could stack directly on pi or use a generic female-female cable. I build my male female cable before I thought of this, so i did not replace(yet) the header on the gertboard. I though ...

Re: led.c (Gertboard_sw_20130106.zip) & buf6 led(gpio18)

Hi Gordon, good thing the drive/swim from your home to my place is so long, so not worth for you to come and kick my butt :oops: LED6 had a life of its own, reboot would change the behavior..... as in "floating" As my colleagues from the hardware board dev team once told me: show some respect to the...

Re: led.c (Gertboard_sw_20130106.zip) & buf6 led(gpio18)

What distro are you running? Raspbian (the one I'd recommend - also the current recommendted one by the foundation IIRC) normally has the SPI (& I2C) modules blacklisted by default... However, that would not affect the first 8 GPIOs - 17,18, etc. that is what I beleived to from reading the spec, so...

Hi Gordon,

Thank you for your proposition.

I will try and update the wiringPI, and run manual tests.
I am attaching the waveform I captured two days ago so you can see what I mean.
The analog probe is on BUF6...

Benoit

hi, I will post a waveform later(at work now), but when I run led.c, my buf6(gpio18) led is not following the sequence it will only lit when all other led are being lit. The buf 6 signal also shows hi to low glitches. I am using: raspian( the version just before the last one, but up to date)(note1) ...

Change to the default skin for the forum (in your account control panel) and there's a global "mark all read" button on the forum's index page. I couldn't find that either when I was on the Raspberry skin and didn't think about switching skins to resolve it... :lol: Bingo, that was it, done... Too ...

Hi, I found no way to mark all the forums read (is there such a way?) I found a way to do it subforum by subforum, but it is time consuming. Without this, it is harder to see how many new (unread) posts were posted since my last visit. ( I am used to clicking mark forum read prior to leaving a forum...

Re: Assembled gertboard & header cable

Sorry for replying to my own post (I cannot find the way to edit my previous post.) on my female-female cable, I removed one of the connector, and try to replace it upside down, flip over, etc.. That did not change the cable behavior. (pin inversion). What did work (see pict) was connecting two fema...

Re: Assembled gertboard & header cable

Since I created a male-male adaptor, I just need to cut the cable and find a female connector, entering the cable f...

Assembled gertboard & header cable

Greedings from a french Canadian, I really like the combination of PI & pre-assembled gertboard (more hardware oriented), but I would like to use a ribbon cable instead of directly connecting them together.
