i want to connect two mirocontrollers together using infrared ,one circuit will be in a rotating cylinder by a way that it will be always in the same direction of the axis of transmission ,the other circuit will be fixed and connected to the pc with serial port
can u suggest an infrared transmitter/receiver that contains seial port interface or that i can connect it easily with microicontroller
thanks too much for your help ,but i donnot wanna use the irda protocol , i will make a simple one ......i just need the led that transmit and that is receiving ...
i will implement any simple protocol between them
is it possible that i connect an infrared led to rs232 transmitter pin on a pic and receive the signal with infrared receiver in another pic in the rs232 receiver pin
on the transmitter side the 555 is used to generate square wave of 38khz.but i think if we connect the IR led to microcontroller without 555, we can generate a frequency of
38khz from the microcontroller i.e if using 8051 it can be easily done using timers.
but may be it will be not accurate.
on the receiver side TSOP1738 is commonly used.
i will connect the pic (rs232 TX) to the 555 circuit to transmit the data
in the receiver circuit .......i will connect the outpout pin from the IR receiver to the (RS232 RX ) will this work ? ....... i mean the byte i send in the transmitter will be directly read by the receiver circuit ....or is there any thing i should do
