This shop can have SUPERTWIST LCD 20 x 4 - BACKLIGHT WITH YELLOW LEDS described here http://www.velleman.eu/fr/en/product/view/?id=339042 with pcb shemas here http://www.velleman.eu/images/products/8/lcd2004a_t.jpg So I would like to know if someone has succesfully test lcdproc with this lcd screen.

The additional information confirms what your first links suggested - the KS0066U is a rather ordinary HD44780-compatible LCD controller. You could wire one of these modules directly to a parallel port or find a suitable microcontroller-based serial or USB converter if your target machine lacks a parallel port. -ethan From sidh at rtha.info Thu Aug 6 09:35:18 2009 From: sidh at rtha.info (Sidh) Date: Thu, 06 Aug 2009 11:35:18 +0200 Subject: [Lcdproc] lcdproc hardware compatibility with SUPERTWIST LCD 20 x 4 In-Reply-To: References: <4A7A963C.4020005@rtha.info> <4A7A9D80.601@rtha.info> Message-ID: <4A7AA3D6.7060407@rtha.info> Ethan Dicks a ?crit : > On Thu, Aug 6, 2009 at 5:08 AM, Sidh wrote: > >> I found more specific information on it : >> >> It is a POWERTIP PC2004A with a S6A0069X (KS0066U, or equipped with >> equivalent IC ) controller. >> > > The additional information confirms what your first links suggested - > the KS0066U is a rather ordinary HD44780-compatible LCD controller. > You could wire one of these modules directly to a parallel port or > find a suitable microcontroller-based serial or USB converter if your > target machine lacks a parallel port. > > -ethan > What a great news, really thank you for this information. One of the motherboard i will rack has only USB, so i will google for the microcontroller USB converter you talk about. Thank you very much.

Just for information: if you're looking for a 20x4 LCD easily useable in your system (accounting you just have USB port available), you should take a look at the one sold by Sure Electronics. http://www.sureelectronics.net/goods.php?id=937 Il could be (far) easier than conceiving / soldering / integrating any home- made controller. And (if you decide to bought it eventually) you will be able to tell me if my driver works for the 20x4 LCD too... ;-) Note: I hope I will not be taxed for advertisement here (being a newbie on this mailing list too I do not know the 'rules'). I am not affiliated with this company at all of course, but having bought their device just for test / fun I must admit it works good for the price and is easy to integrate in a computer. -- - Laurent Latil - -------------- next part -------------- A non-text attachment was scrubbed...

Message-ID: <3c5546140908081556w13089661kbf79c8ee8e2d25e2@mail.gmail.com> Hi, I am designing an analog CPU usage meter for my linux box. The basic design (soon to be posted) uses a BS2 microcontroller and Maxim5250 DAC. The current setup translates serial input data (0-100) into an analog voltage sent to the meter. It would be simple enough to periodically send a bit of data out the serial port with a little python program or the like-- but it would be nice if I could take advantage of the server-client nature of something like LCDproc. So, the main question: is there currently a driver that can send unformatted data to the serial port, or would this need to be written into a custom driver. if so, how hard would this be? All I need is a simple '%i\n' sent to the serial port where %i would correspond to the integer representation of the current CPU usage. I have limited knowledge of C programming, but no experience with the LCDproc codebase. Also, I will post the complete details of the completed project for anyone else that may be interested. Thanks in advance!

It is up to the driver to do something useful with it. Originally it was intended to drive some LEDs connected to the parallel port, which is similar to your project. However, as LCDproc is intended to drive displays this is an optional auxiliary function of a driver. Output drivers are required to have the functions to print text on a display, although you may write a driver which completely ignores any text sent to it. On the other hand I have no experience if LCDproc is working well with two output drivers (one for a display and one for your device). Additionally you have to write a client which collects CPU data and sends it to the server using the 'output' command, as the current client displays it as some text and bargraph on a LCD screen.

Message-ID: <4A80710C.4040200@simmons.titandsl.co.uk> I've updated to fedora 11 on my antec fusion (imon vfd with ir), and I'm finding that about half the time the goodbye message isn't being set. The antec keeps the display powered when 'off' so it ends up stuck displaying whatever was last on the screen, usually the default/background server which is a bit rubbish. I'd guess it fails about half the time, maybe a bit less frequently but something of that order. Has anyone else seen this / its a known issue / there's a workaround or something? I was wondering about tweaking the chkconfig priorities but they look sane as far as I can tell. My guess is that LCDd tries to write asynchronously to /dev/lcd0 when its shutting down and sometimes by then lcdproc has shutdown and the device has already gone bye-bye. Cheers, Chris Simmons.
