Re: [emulatorII-list] Re: EII LCD Display

2010-10-21 by Damir Rogina

I just decided and order �few Displays of ebay!!!!

i realized that all old displays are using same Type �of Processor HD44780�

EII
EMAX
SP12
Prophet VS
Studio 440

all using 16x2 LCDs
they are compatible with new ones BUT
be carefull some devices like emax have no space for 12 mm of new LCD displays!!!�

old displays are 8mm (lcd 5,1mm+ pcb 3 mm)
some new displays are  12mm (display 5,1mm + LED area 4mm + PC 3mm)

big improvement with new displays is :

LED backlight or VFD displays from noritake
no need for hi voltage and inverters that produce hi pitched noise
all displays are pin to pin compatible... just get instructions, get soldering iron and some wire!!

this is pin out of all Displays!!


Pin1 :� GDN - 
Pin2 :� VCC +
Pin3 : Contrast for Display - Using 10k resistor mostly
Pin4 : RS (Register )- For high power to select the Data Register , low power to select Instruction Register .

Pin 5 : RW(Read and Write ) - high power for Read , low power for Write .
If� RS and RW are low power , it will read a data to show on the screen address.
If RS is low and RW is high, it will read a data and busy signal.
If RS is High and RW is Low, It can write a data

Pin 6 : E (active port) , from High to low will action a Instruction�;
Pin 7~14 : D0 ~ D7 are data port .
�����  ( Standard port :
�������� For Microchip��� :������� RB0 ~ RB7 = D0 ~ D7
�������� For 89S51 MCU :������ P1.0 ~ P1.7 = D0 ~ D7
�������� For AVR�� �������� :��� �� PA0 ~ PA7 =� D0 ~ D7� )

Pin 15~16 : Backlight + and -� (AK)
The LCD is includes a 160 words in CGROM which are number , symbols ,English words and Japanese.



JUST ordered this one to try!!

OK, response from Bruce Forat:

'The ones that we use have LED backlight (Blue/ White text) same as what you see offered for the SP1200 on our site at www.forat.com/service however they are not direct replacements and require mods. There's someone selling the original SP1200 displays on eBay and I think it should work on the EII as well':

http://cgi.ebay.com/E-MU-EMU-SP1200-SP-1200-SP-1200-Replacement-Display-/290475275179?pt=LH_DefaultDomain_0&hash=item43a1acf3ab

$104 is steep but attempting to clarify the make/model of these with the seller. Also found someone in UK that appears to have replaced theirs and will update if/when further details come back.
