Hi All,
I'm trying to determine the feasibility of sending 4096 bytes between two PICAXEs, using just IR.
From Manual 2, for the Sony protocol, a Logic level 1 is transmitted as a 1.2 ms pulse, logic 0 as a 0.6ms pulse. Each bit is separated by a 0.6ms silence period.
Using the above figures, the maximum length of a bit is 1.8mS including the inter-bit silence.
4096 bytes = 32768 bits, which gives a maximum time of 32768 * 1.8mS, which is 58.98 seconds.
I am intending to use PWM to fake the Sony protocol, so I can use the full byte instead of just 7 bits.
Then I will then use PULSIN on the second PICAXE to decode the pulses from the IR receiver.
Both PICAXES will be 28X2-5's.
Does this seem feasible ?
Or better still, is there a solution in the forum somewhere ?
Cheers,
Buzby
