PIC16F8xx and 128×64 GLCD
Thursday, January 21st, 2010 | Author:

I looked at Microchip & Hitech picc, Mikro C, CCS and others. I went back to JAL, 1/2 a day got graphics library for KS0107 / KS0108 used in JE-AN1286404 Graphics LCD working. Animation, Circle, arbitrary lines, box etc. Also text compatible with Text LCD libraries & programs.

I'll be using this in a few projects. Pinout is different from usual KS0107 GLCDs:

HQM1286404 / JE-AN 1286404 LCD Pin connections:

1: VDD is connected to +5V

2: VSS is connected to OV /GND

3: V0 – LCD operating voltage is connected from a 10K or 20k Ohm POT (Between OV and -5V from pin 18)

4 .. 11: Data Bus 0 to 7 is connected to port d

12: Chip Select 1

13: Chip Select 2

14: Reset  (hold at +5V for normal operation)

15: R/W – Read=1 or Write =0

16: D/I aka RS – Data or Instruction (Registers)

17: EN Enable is connected to B5 18: Negative voltage out to feed 20k Ohm POT for view angle

19: Positive voltage for LED backlight is connected to +5V

20: Negative voltage for LED backlight is connected to GND. On my pre-wired panel this is red wire! (feed LED backlight via 47 Ohms in series with + or – pin.)

I had to reverse CS1 and CS2 in the JAL library, but the wiring above works with LCDStudio for PC parallel Port (RW = 0V and RESET aka RES = +5V, connect Power first! I used USB for +5V) More details with projects, schematics etc on http://www.techtir.ie soon

Tested on PIC16F877A 20MHz using JAL. Same SW should work on 16F887 (replacement) and others with enough pins.

Other models of GLCD that are compatible may have different pin layout and even +5V and 0V reversed (even on similar model names of same make!)

Ireland Bottom of Another Bandwidth-Driven Pile.
Friday, November 13th, 2009 | Author:

A survey released today by Tariff Consultancy1 has revealed that Ireland is now the most expensive country in Europe in which to lease Data Centre capacity. After getting a broadband connection the first reaction of most people and companies is to establish a presence on the internet, usually a web site. However the cost of renting space in a datacentre is prohibitive .

This shocking report is a result of a myriad of policy failings over the medium term since around 2001, not only in the lack of an overall balanced National Broadband policy but also because our only energy policy is to have the most expensive electricity in Europe, by design. Data Centres are the very heart of any functioning knowledge economy, they are where knowledge and data is stored and and from which the kowledge underpinning the economy is distributed.

Pricing Irish business out of these Datacentres may seem smart and green to some but this smart green policy will have disastrous consequences over the medium term out to 2015, not least to our GDP. Ireland Offline calls on Minister Ryan to address these deficiencies as a matter of extreme urgency. Only 2 data centres have opened in Ireland in the past 8 years, one in Cork and one in Dublin. No more are planned.

http://www.telecomspricing.com/news_detail.cfm?item=2592 “The most expensive average Data Centre countries in our survey are Denmark, Switzerland & Ireland (with rates per rack from 1,300 Euro to 1,050 Euro per month), with cage and 50 KVA pricing being significantly less (in Euro per square metre terms).” Ireland led Europe in the quality price and availability of its Data Centres in 2001. We have built only 2 since, one in Cork and one in Dublin. Data centres are huge computer warehouses where ones data is stored, even though we are supposedly a “leader” in the knowledge economy stakes.
