This is matlab simulation. Signal is output of modulation. IS purely binary representation with out any line or source code for the input. so the output should be purley binary represenation (i.e, high is logic 1 and low is logic 0)
The model above obtain from web site.
Question, i just want to try a 'noiseless' channel (without any channel) by modulate and immidaitely demodulate. But why there is error? Shouldn't is zero error?
2. the output of the FSK modulator should be analog signal, right? how come cannot use the...
For PIC side, where can i find the protocol of interfacing with PC? Because I did try to find about UART interfacing. I am seeing lot of code using thing like "TXIE", "RCIE". I have no idea on this.
I mean i need to know how the pic know the data is comming from PC, and what the PIC going to...
Hi,
I am really a new to interfacing. Lot of thing dont understand. Hope your can guide me on this.
I am doing a project to interface the PIC and PC. The PC should send a data via C program from serial port and to PIC and PIC display it on the LCD screen.
For PIC to LCD, i already manage to...

interfacing serial
Since we program a mcu using serial port (+/- 13v), why not we just use a rs 232's converter to convert all (max 9 pins) to 5 V/0V. Why we still need a complex prgrammer?
we just need to have a algorithm to program the mcu and hence we can then write a program so that the...
The computer have 2 serial port ...
when we programming the port, how to know which port is com1 and which is com2?
For different assembler, will it produce a different hex code for a same mcu for same program?
Re: New toMCU (programmer)
About programmer, is the software use for programming (sending hex code to pic) only match it's own hardware programmer?
Actually how the pc communicate with the pic?
pic bootloader oscillator
Isnt bootloader also a tye of serial programming?
Is any one of you have circuit and software for "serial programming" and bootloader?
Thanks
Re: New toMCU (programmer)
Thanks to Normad13 for replay.
But yet, for bootloader (hardware),can we write one program on our own? if how can we do it? Any material for this?
Also, i read in some where, it say before we use bootloader, we required to use the programmer for once-off progrmming...
tomcu
HI all,
I am new to PIC mcu. However, i do know some basic as shown as following diagram.
My question are, what is the different between bootloader and programmer?
Are they the same?
Is bootloader also consider a ICSP?
The "software for communication" is to put the hex code to...
