spidev config

I've been struggling all day to solve this, and have clicked probably the first 3 pages of links in google related but can't crack it. I have another post on here regarding the Nokia Colour display and the speed problem, so I have now reverted to spidev to get better performance rather than bit bash...

Re: Nokia Colour Display

Well after looking at the shiftOut routines for wiringpi, they seem quite similar to mine except that this is 9 bit and not 8: for x in xrange(8,-1,-1): wiringpi.digitalWrite (SDAT,DAT & (1 << x)) wiringpi.digitalWrite(SCLK, 1) wiringpi.digitalWrite(SCLK, 0) So I've started to look at spidev and hav...

Re: Nokia Colour Display

Hi; Yes, good question, well for a start there are 26, 316 pixels to be set on the screen, with the start and stop bits and the 9 bits of data that is roughly 290,000 clock cycles for a complete screen. The clock pulse width is around 6 us and the fastest clock frequency I am seeing is around 21us o...

Nokia Colour Display

Hi all; Have now managed to get the Nokia 6100 Colour Screen working with python's wiringpi bit-bashing and an old breakout board I bought from sparkfun several years ago (they have since revised the design). This is a great little display, it uses 9 Bit SPI and is supplied with 2 different chipsets...

Re: Serial Console Test

OK, solved.

Seems like the Serial > USB Adapter does not like 115200, slow it all down and everything is working as expected.

Thanks anyway !!

Re: Serial Console Test

I have also created a loopback from the putty serial connection by linking the TX and RX pins and what is being transmitted by PUTTY is correctly echoed back.

Serial Console Test

Hi; I am connected @115200,n,8.1 to the PI on the RX & TX Terminals via Max232, all of the text is outputted to PUTTY correctly during boot up, however when the booting is completed, the format does not look the same as a SSH Console and I am unable to login or communicate via putty, and I get spuri...

Re: WiringPython - WiringPi for Python

Hi;

Thanks so much for all the work on this, but would it be possible to include wiringpi's latest support for interrupts, ?.

It is exactly what I need to solve a problem that would otherwise involve a tight loop and lots of cpu usage

Many Thanks

Re: login

I can assure you it most definitely is NOT raspberry, as I have just downloaded and installed it, raspberry is not accepted as password either via ssh or local terminal.

The password is suse on the version I downloaded "debian6-19-04-2012"

Cheers

Re: Cases for the Raspberry Pi

Thanks, but I will be making my own case, hence the need for the drawings in advance of the actual boards.

Re: Cases for the Raspberry Pi

I've searched the wiki and website and can't seemed to find a mechanical drawing of the board showing dimensions to the various connectors.

I'm sure there must be one, can someone point me in the right direction ??
