Dear, I am a new one in this field. I have a project of Receiver (HIVION made Korea), TV (LG Model LD420) and controller HC200B. Now I want to control the TV and receiver by touch screen and SR250. I already create drivers for receiver and TV drivers were available on on-line data base. Now I have no more idea, how to program these devices. Anybody have a potential to help me as soon as possible. You can send e-mail to me zaheer_eng2007@yahoo.com Zaheer Abbas from KSA
