Other Parts Discussed in Thread: DLPA2000,
Hello:
Board info : dlpc3438+dlpa2000+dmd
Use the specified read command, i get the Controller-Device-ID is 0x05, DMD-Device-ID is 0x60 0x0D 0x00 0x87.
This system already works, the DMD generate the correct screen in test Pattern.(Color bars, Horizontal lines, etc)
I can correctly control the Test-Pattern-Select to show different images, and control the LED Current to make image more brightly.
But when i need to set the image display size, or make image Orientation, it does not work!
For example, I want to sent the display size to : 1280 * 360
My control Command as this: x_dlpc_wr 2 0x12 4 0x00 0x05 0x68 0x01
Op.Cmd | DLPC.No | Op.Code(Write Display Size) | Length | Byte1 | Byte2 | Byte3 | Byte4 |
x_dlpc_wr | 2 | 0x12 | 4 | 0x00 | 0x05 | 0x68 | 0x01 |
And, of course, I tried a bunch of configuration parameters, no one works, And i don't know why.
I guess there are some reasons for this problem:
1> My Config parameters is error. (This is unlikely to go wrong, Because some of the configuration items are already working correctly)
2> The firmware(Boot Code) on the external flash have some weakness.
3> May be some hardware error,etc
Please help me solve this problem.
Thanks a lot,Best wishes!
