Sharp LCD IR Pulse Issue

Postby bkankur on Sat Jun 20, 2009 8:20 pm

Dear All,

We are trying to generate IR Pulses for Sharp LC-19AD22U LCD. Promto code for Power On/Off is shown below.

0000 006D 0000 0020 000B 0045 000B 001D 000B 001D 000B 001D 000B 001D 000B 001D 000B 0045 000B 0045 000B 001D 000B 0045 000B 001D 000B 001D 000B 001D 000B 0045 000B 001D 000B 06C3 000B 0045 000B 001D 000B 001D 000B 001D 000B 001D 000B 0045 000B 001D 000B 001D 000B 0045 000B 001D 000B 0045 000B 0045 000B 0045 000B 001D 000B 0045 000B 0672

Using our Device we are generating IR pulses based on above promto. But the tricky part is that we have to generate IR pulse twice for whole promto then only the LCD interprets the command. We have also verified with Oscilloscope that pulse is generating correct.

Any suggestions why its happening?

Its strange!!
Ankur.

What IR Blaster device are you using to learn and retransmit IR codes with xLobby. Are you using the freeware xLobby or are you a xLobby V3 customer.
