Thu, 04 Dec 2008 16:24:52 -0800 http://backend.userland.com/rss092 hi rickey!i want to make a project for my summer vacations..i am interested in the project " controlling appliances with Infrared" using 8051. i have <noauthor@nospam.com> http://www.8051projects.net/forum-t1349.html for IR project, you must start with sending data via IR. For this.. you need... an IR transmitter and IR receiver. IR transmitter is of course IR LED Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1349.html yes you can do that too.. but it just reduce the load from the IC. and you can be sure of accuracy when u use separate hardware. 555 can generate squa Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1349.html we have to generate pulses of 38kHz, so why to use 555 ic ? we can generate it using 8051. what do u say!!?? abbas1707<abbas@nospam.com> http://www.8051projects.net/forum-t1349.html yes that is my code i need to make little changes to make a simple project on it like you can control 8-devices. I am making schematic for this.. Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1349.html Why don't u use commercial remote control as transmitter? just built the receiver.I have done with project like this but using PIC16C84A. U can contr zerisha<zerisha@nospam.com> http://www.8051projects.net/forum-t1349.html Yes please post ur code and schematic... I want to built another IR Remote Control. zerisha<zerisha@nospam.com> http://www.8051projects.net/forum-t1349.html I already posted it in the download section Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1349.html As my comment at download section, i have to compile the asm code, but there is many error. Please post the hex code.. Can it modified, to add RC5 zerisha<zerisha@nospam.com> http://www.8051projects.net/forum-t1349.html hmm.. you can add.. after the valid check is done..In the code after label valid1i compiled the same program.. also using it.. no errors so far. can y Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1349.html This the error message :1 Undecodable line, Syntax error 4 Undecodable line, Syntax error 5 Undecodable line, Syntax error zerisha<zerisha@nospam.com> http://www.8051projects.net/forum-t1349.html which software you are using to compile the program?i recommend you to use Keil. as the code is less than 2K so you can make use of demo version of ke Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1349.html Can anyone guide me which particular brand's TV remote can be used with this?And can I change the code to work with some other brand's TV remote? say2paul<say2paul@nospam.com> http://www.8051projects.net/forum-t1349.html if you want a different brand remote to work, then you need to implement its protocol.which brand you're thinking? i can provide you protocol informat Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1349.html I want to use IrSIR to send IR signal to this IR Switch using my Symbian mobile phone.
