X19A-B-005-05 Issue Date: 01/02/01
Usage
PC platform: at the prompt, type 13504play [/?].
Embedded platform: execute 13504play and at the prompt, type the command line argument.
Where: /? displays program revision information.
The following commands are valid within the 13504PLAY program.
X index [data]
- Reads/writes the registers.
- Writes data to the register specified by the index when
“data” is specified; otherwise the register is read.
XA
- Reads all registers.
D index [data1 data2 data3]
- Reads/writes DAC values.
- Writes data to the DAC index when “data” is
specified; otherwise the register is read.
- Data consists of 3 bytes: 1 red, 1 green, 1 blue.
DA - Reads all DAC values.
L index [data1 data2 data3]
- Reads/writes Look-Up Table (LUT) values.
- Writes data to the LUT index when “data” is
specified; otherwise the LUT index is read.
- Data consists of 3 bytes: 1 red, 1 green, 1 blue.
LA - Reads all LUT values.
F[W] addr1 addr2 data . . . - Fills bytes or words from address 1 to address 2 with
data.
- Data can be multiple values (e.g. F 0 20 1 2 3 4
fills 0 to 0x20 with a repeating pattern of 1 2 3 4).
R[W] addr [count]
- Reads number of bytes or words from the address
specified by “addr”. If “count” is not specified, then
16 bytes/words are read.
W[W] addr data . . .
- Writes bytes or words of data to address specified
by “addr”.
- Data can be multiple values (e.g. W 0 1 2 3 4
writes the byte values 1 2 3 4 starting at address 0).
I
- Initializes the chip with user specified configuration.
M [bpp]
- Gets current mode information.
-If “bpp” is specified then set that pixel depth.
