peek( addr, [n] )
- Reads one or more bytes from contiguous memory locations starting at
addr.
- addr
-
- The address of the first memory location.
- n
-
- The number of bytes to return. (1 by default, 32767 max.)
The peek() function reads and returns one or more bytes from the addressable memory region (0x0000-0x7fff).
See Memory for information about the memory layout.
See peek2() for a way to read groups of 16-bit values from two consecutive memory addresses, and peek4() to read groups of 32-bit values from four consecutive memory addresses.
@ operator[]
The unary-@ operator added in 0.2.0 performs the same function as peek(address) and is now the recommended way to read one byte of memory at a time, as it uses fewer tokens, costs fewer cycles at runtime, and runs on the real host CPU much more efficiently. Simply replace peek(address) with @address.
Examples[]
b = peek(0x4300)
b = @0x4300 -- preferred method
delay,interval = peek(0x5f5c, 2) -- assign variables with the btnp() settings
