	Once stored, characters can be recalled into a text string by either using the unicode value for the location as referenced in the ASCII ~~chart (Appendix A)~~ or by using the String Code method from the API. Examples in C# of both methods are shown below:		Once stored, characters can be recalled into a text string by either using the unicode value for the location as referenced in the [[LCD_Character_Display_Primer#ASCII_Chart\|ASCII Chart]] or by using the String Code method from the API.

	Liquid Crystal Displays are display devices used to convey information through arrangements of pixels. Graphic and Text LCDs are the most common types available for electronic products. The 1204 supports the following screen sizes (lines x characters): 1x8, 2x8, 1x16, 2x16, 4x16, 2x20, 4x20, 2x24, 1x40, 2x40, 4x40. Please note that your program has no way of automatically detecting the size of the attached screen, so you need to set the screen size with call from [[#API\|the API]] in order to have text strings display properly.

	Custom characters can also be generated for the PhidgetTextLCD. A custom character can be any arrangement of pixels within the space allotted for a single character. Single characters are made up of pixels arranged in a grid 5 pixels wide by 8 pixels high. Once generated, custom characters can be stored in any one of eight volatile memory locations on the PhidgetTextLCD, and can be recalled with a simple API command from software. When custom characters are designed, a formula is used to change the pixel design into a pair of numerical values. The first value relates to the design of the top 4 rows of the character, and the second value relates to the design of the bottom 4 rows of the character. Unlike the unicode characters used in the Special Characters section above, the calculated number is not in hexadecimal format but is an integer value up to six characters in length. The calculation for custom characters can be done by hand, or can be completed for you by using the form available at www.phidgets.com/documentation/customchar.html. Done by hand, each integer value represents the sum of two to the power of each individual on-pixel’s location within that integer-value’s half of the character. Pixels not turned on are valued at zero. For example, a custom character happy-face with pixels 6, 8, 11 and 13 in the upper half turned on, pixels 1, 3, 6, 8, 11, 12 and 13 in the lower half turned on, and all other pixels turned off, would result in the following integer values.
