Pete says: "Your 2x16 LCD panel is hot! Any chance you have a 4x24 unit in the works?" James Newton answers Sorry, no. These are one of a kind, overstock items that will no longer be available when the existing stock runs out. I can't begin to make such an item for this price.

juanmarod says: "Thank you. Very good Displays. Every think ok. I put you a positive feedbak on Ebay."

John Muchow says: "James, I just received my order of three LCD Front Panels, thanks for the great service! I'm looking forward to getting my PICs hooked up to them. :-)"

Tom Lackamp says: "I spread the module's pins out at a 45 degree angle, then took the last .200 or .250 inch and formed them back to the vertical so I could plug them into the breadboard using .300 spacing." Toms modification allows the LCD module to be used with a standard "whiteboard" breadboarding system. Since the connector pins are quite long, even after being bent, they seat into the breadboard firmly.

  Questions:

• Any chance this panel canbr driven by 3.3v supply & I/O? Thanks - Steve James Newton replies: No, sorry, it needs 5 volts.

• akiroz_dunk@yahoo.com asks: " hi.i`m is interest in your project.can you display the source code for that project,please??" James Newton replies: See http://www.massmind.org/techref/io/lcd/44780.htm

• cstanleyw4@comcast.net asks: I was wondering if the PIC16F690 would be appropriate for use with this? It would seem you designed this with the PIC16F877 in mind so I thought I'd ask. James Newton replies: Absolutly.

• charlie2224@msn.com asks:

  Hey, I am way new to this whole LCD Panel + microcontroller stuff, can you give me a few links to places where I can learn to write and load software onto this thing? I really love this product and it's exactly what I need!

  James Newton replies: See: /techref/io/lcd/44780.htm

• caramel_s_t_m@hotmail.com asks: " does this works with 4 and 8 bit mode ? is the EN pin is 5 or 6 ? in it supports 4 bit mode , do I have to ground the none used pins ? thanks" James Newton replies: As with any 44780 LCD both 4 and 8 bit modes are supported. Enable is pin 5, and you can ignore unused pins.

• caramel_s_t_m@hotmail.com asks: " I'm using the basic stamp2. Is this lcd compatible with it" James Newton replies: Yes!

• jochen.burkert@hap.com asks: " Hi I`m using a PIC18F4580 and want to know if your display is compatible to it. Regards Jochen" James Newton replies: Sure! Any microcontroller with a few IO lines free should be able to use it. We do NOT supply sample code but you may be able to find it on the net.

• Randy G Glenn asks: " James, will you ship these to Canada? (USPS preferred due to UPS' insistence on gouging) Also, is shipping $5 per unit or $5 per order? Thanks!" James Newton replies: Randy, for you I would ship to Canada via USPS Air Parcel Post for $10 per order up to about 20 units. That is only because I know you. My standard price for international shipping is $20 via USPS REGISTERED Air Mail. These are also being auctioned on eBay and you might find a better shipping option there.
