offcourse using oscilloscope to decode IR signals is practical..
search for RC-5 and REC-80 codes.. most of d remotes use these ..
and there are many ways of decoding
Re: 8051 and IR LEDs
it has open drain output so as to interface with external memory..
We need a true bidirectional port for interfacing of memory.. and PORT 0 serves as both data bus ( D0-D7) and lower address bus( A0-A7).. these are time multiplexed
and lower byte of address is latched with...
Re: Build easy MPLAB-6 ICD-2
Hey Guyz thanks for all the wonderful information on ICD2.
I have made the RS232 ICD2. Will be making the USB one if i can get the parts at my place.
Anyway i just wanted to know if there was any way of programming the dspic which requires lower supply 3.3 volts...
Well basically wut happens.. and interrupt call , stops the microcontroller to function normally rather the program jumps to another function called Interrupt Service Routine to finish of the job it has to do in that function.
So when an interrupt calls.. the priority is checked and that...
Well embedded c is nuthin dat special.. itz just normal c with a few extra syntax .. and a lil restriction.
Every complier will have some different syntax.. so itz basically which microcontroller ur using , which will decide which compiler to use .
Keil C supports most of the Micrcontrollers...
simple circuit .. just visualize wut i am writing::
take two npn transistors .. connect their collectors 2gether with a + supply
their emitter together in series with a single emitter resistance with -suppy.
and the two inputs at the two bases respetively.
The Output is taken b/w the two...
