I've used the **broken link removed**on my IR projects
Special Features
• Enhanced data rate of 4000 bit/s
• Operation with short bursts possible (≥ 6 cycles/burst)
As for generating an IR pulse, well I had issues modifying the UART library to control the PWM module on board the PIC in Swordfish, but I found a much easier solution...
Simply setup a 38Khz PWM signal, route that signal too one input on an **broken link removed**, and the output of your UART TX pin from your PIC to the other AND gate input. Wire up the output of the AND gate to a driving circuit, eg, ULN2003, to control the **broken link removed**. The result, 38Khz modulated UART.
Works best with low speed bauds (eg, 300 b/s to 600 b/s)
