I have purchased Easy VR STAMP board with the schematic included.
I need to know exactly the devices used in the board.
- what is the code and the producer of the MAX232 on board?
- what is the code and the producer of the 74hct245 on board?
- what is the code and the producer of the microphone on board?
- what is the code and the producer of the speaker on board?
- what is the code and the producer of the lcd 2x16 on board?

Is it possible to known the schematic included in the box "Easy VR-STAMP On- Board Programmer" ?

Thanks.

Hi,

Is it possible to known the schematic included in the box "Easy VR-STAMP On- Board Programmer" ?

We cannot give you schematic of programmer.

The producer of the MAX232 is Texas Instruments.
The producer of the 74HCT245 is Philips.
The producer of the LCD 2x16 is (if LCD is green - Xiamen Ocular GDM1602A,
if it's blue - LongTech Optics LCM1602A-NSW-BBS)

Driver for mentioned board is the same one as for EasyPIC5.

Thank for your answear.
I purchased a 2x16 LCD with 16 pin (the first two ones are for the backlight).
The product is DISPLAYTECH 162B. I tested it with the demo program for LCD in Mikro's Examples. But It doesn't work.
Do you think that the problem is due to the different display that I used, instead of using those ones that you suggested me?

Hi

The problem is probably with LCD.
DISPLAYTECH 162B has different pinout.
Display Xiamen Ocular GDM1602A and
LongTech Optics LCM1602A-NSW-BBS have this pinout:
Vss (pin1)
Vdd (pin2)
Vo (pin3)
RS (pin4)
RW (pin5)
E (pin6)
pin7 - pin14 data
LED+ (pin15)
LED- (pin16)

Try to find information about GDM1602A on internet or send me e-mail
and I will send you datasheet for GDM1602A display.
My e-mail is dane.radakovic@mikroe.com

Sorry for late respond.
