How to compare strings/array? RFID Project

[astanapane]

here you can see a demo of the RFID circuit.



I need now to improve it with GLCd and Keypad.

i would like to say thanks to Mr. Ioannis for his patient and help.

I need now to improve it with GLCd and Keypad.

If this is a one-off (which it appears to be) and price is not an overwhelming obstacle, then look at a serial Graphic LCD such as this one http://www.sparkfun.com/products/9351
Besides writing text, this serial graphic LCD allows the user to draw lines, circles and boxes, set or reset individual pixels, erase specific blocks of the display, control the backlight and adjust the baud rate. It costs $35 and you won't need a GLCD library.

Better yet, this full color TFT has a built-in touch screen so you won't need a keyboard http://www.sparkfun.com/products/10089 - it costs more at $85 and is fully programmable OR can can be controlled with a serial port.

hello rmteo,

thanks for your advice.

I dont know about the serial lcd. Can i drive it form a pic18f4550 for example?

Could you give me some instructions? a sample code? I will first use the serial lcd and then i will try the color.

How is the serial GLCD working, and why i dont need a GLCD library? As i see on the serial there is an ATEML chip. I dont know how to programm ATMEL. Sorry for my questions.

Thank you very much for any help in advance.

Kind regards,

astanapane.

The serial GLCD can be used with any MCU (including the PIC184550) that can output serial data. You do not need a GLCD library as it is an intelligent display that has an AtmelAVR MCU on board - you could say that the library lives in the AVR.

I do not provide sample code. You send simple ASCII codes using SEROUT (or HSEROUT) at up to 115,200 baud. Take a look at the datasheet here http://www.sparkfun.com/datasheets/LCD/Monochrome/Corrected-SFE-0016-DataSheet-08884-SerialGraphicLCD-v2.pdf and and the tutorial here http://www.sparkfun.com/tutorials/120

so using picbasic, can i include a file on my code with a picture?

thanks a lot. Sorry for missanderstanding about a sample code. I didnt ask for an actual code but an example.

Thanks anyway for give me the information.

Kind regards,

Going by the datasheet of the serial GLCD, it is obvious that the code in the AtmelAVR is pretty limited in capabilities. It can do text, pixels, lines, boxes, circles and not much else.

If you want to do pictures, then look into the COLOR LCD. It is a far more capable product that can even do full motion video (in color) as shown in the video. I have one and would highly recommend it. Full info here http://www.4dsystems.com.au/prod.php?id=114

In fact, since I no longer have a need for it, I may consider running a contest to give it away.

thanks i will look for an LCD that is capable for my needs.
