G SD Get Screen Dump.

Explanation: Outputs a comma delimited dump of the display memory. The

result is formatted in two-digit hex values separated by commas. 1024 values

will be returned in this format representing the 1024 bytes of display memory.

To format these values to a display, you have to know the memory organiza-

tion. The memory is returned in 8 rows (Y) of 128 columns (X) starting at 0,0

and ending at 127,7.

Each row is made up of 128 one-byte hex entries, which covers an area of

128x8 pixels. Each byte in the row contains 8 pixels worth of data, and the

MSB bit of each byte represents the highest value in the Y direction. For ex-

ample Bit 0 is Y=0 and Bit 7 is Y=7 on the first column. See the table on the

next page for more information.

Example:

G SD<CR> sent

C0,AA,CE,C0,80,80,80,... (1023 entries total) <CR><LF>

returned

1 2 ... 14 15 16 17 18 19 20 21 22 23 24 ... 31 32
