BlocklyProp reference for VALUES blocks

Block availability varies by board type.

number value

Compatible with all Propeller board types (except Scribbler Robot)

The number value block is a value that is usually placed in or attached to other blocks that are expecting a numeric value. Any numeric value can be typed into the block. Non-integers will be truncated to integer values.  Any integer value from 232 to 232 -1, which is -2,147,483,648 to 2,147,483,647, can be entered into this block.

text string

Compatible with all Propeller board types (except Scribbler Robot)

The text string block is a string of text that is usually placed in or attached to other blocks that are expecting a string of text. Any text can be typed into the block. Some blocks limit the amount of text they can accept to 128 characters.

(Note: previous versions of this block lacked the quotation marks.)

The constant value block returns the value of a named constant.

color

Compatible with all Propeller board types (except Scribbler Robot)

The color block provides a 24-bit integer representing the color selected. The value provided is derived by the following formula: (Red << 16) | (Green << 8) | (Blue). In a 24-bit number, the left 8 bits represent the amount of red, the middle 8 bits represent the amount of green, and the right 8 bits represent the amount of blue.

The compare colors block provides a value from 0 (opposite) to 255 (identical) representing how close two 24-bit colors inserted are.

system counter

Compatible with all Propeller board types (except Scribbler Robot)

The system counter block provides the current system counter value at the moment it is asked for. The system counter increases by 1 for every system clock “tick,” and there are 80,000,000 ticks every second on the Propeller Activity Board (PAB) and PAB-WX. When the system counter reaches 4,294,967,295 it resets back to zero.
