DS_SYS_UartRead
1212
Perform an UART read action on the digital board on a specified UART
- Decode the user input for the port to read from
- Read from the port and return data read to the user
Less than 1 second.
The user inputs the UART to read from.
1=UART port 1 : not used
2=UART port 2 : Bit DVDR Mechanism
3=UART port 3 : Analog board
<UartNr >
Number Description
121200 Reading the data from the UART succeeded
121201 The user provided wrong input
121202 Reading the data from the UART failed
DS:> 1212 2
121200: The value that was read is: 0x50 0xD1 0x00
Test OK @
DS_SYS_VideoLoopThroughStart
1213
The video signal, which is confirm the user input, is routed from the input to the output. Input
is set with the routing nucleus 1112. All outputs are enabled.
- Decode the videosignal: PAL / NTSC and Y/C, RGB, CVBS,YUV
- Initialize the Video Input Processor and check for valid signal
- Initialize the Video Front End and start capturing frames to memory
- Initialize the SYNC module
- Initialize the Video Post Processing and retrieve frames from memory
- Initialize the mixer
- Initialize the DENC module
- Route the signal to all outputs
Less than 1 second, but stays running.
