Hi, guys! So I am doing a project for an embedded development course. My instructor wants us to use a PIC Microcontroller and we settled on: PIC16F877A. I downloaded MPLABX IDE, IPE, and compiler, but I am looking at the interface and I don't know what to do or where to start. I also want to simulate before buying anything. Is that even possible? I read online for a bit but what I found was either out of date or not helpful at all. Any help would be much appreciated.
Thank you!
Hello, I have a PIC microcontroller that sends data to another PIC microcontroller by UART, however, the distances are very long and noise gets in the way. I did some research and one of the solutions would be to implement the so-called Hamming Codes, however I'm totally new to this sub-domain of signal processing I don't even the slightest idea how they work. Can somebody help me out, please? Or at least offer me a better solution.
I am trying to make a reliable data transmission using wireless modules which work with UART. I've tried to use some 433MHz Tx&Rx modules (XD-FST / XD-RF-5V), but I only managed to get them to work only a few inches apart from eachother, then the signal got really noisy and the receiver couldn't figure out the data anymore. I've tried implementing a checksum, which I transmitted after the 8-bit useful information, but the result was the same. Which other error preventing/correcting countermeasures can I take? I am using PIC16F887 microcontrollers. I tried searching for the so-called Hamming codes for this kind of PICs but I coudn't find anything useful.
