Hi Andrew,
I think I understand the concept: you are suggesting that I use 6 ports to output 1 bit every 4 instruction cycles, doing this 8 times for a single byte. It feeds this into 6 individual ...

Hi asmallri,
I understand the basic principles of creating a software UART, but without a master or slave, if chip A is sending information to B, and B is sending information to A at the same time ...

asmboy- I was able to find a few UART's with 2 channels that contain transmit and receive ready functions built into the hardware, but I do not yet see how I can use these for 6 channels. Are you talk ...

9600 baud (though this can be changed), small data chunks

full duplex, asynchronous communication is a must (to answer your master/slave question)

the buffer size required is only 1 to 2 bytes f ...

Thank you all for the thoughtful responses. I do appreciate it greatly.

I had migrated from a 16f877a to a 16f1824, without any hiccups. If the process would be similarly easy to the 24 series, I ...

Hi All,
I have been programming 16f877a chips and below, and am no expert by any means. My latest application requires the use of at least 3 hardware UART's, so I am looking at the 24 series. In or ...

Ttelmah,
I have been trying a few things with not too much luck, and now I am trying to make sure I understand you correctly. Correct me if I am wrong, but pointer operations require that the elemen ...

I forgot to mention, your second piece of advice regarding how to declare the font tables is working fine. Thank you!

Hi Ttelmah,
I removed the first bracket but it still gave me a syntax error...but lets skip that for a moment and perhaps fix the other problems.

I am declaring my fonts before the function d ...

Hi All,
I have spent quite a bit of time trying to educate myself on pointers and how they can be used to display characters from large arrays. I even have (presumably) working code for the screen ...

Thanks temtronic. Are there any suggestions as to specific memory chips I should look into, preferably ones whose use is well documented?

Hi Ttelmah,
Are you aware of any resources which would help me find a suitable EEPROM? I need plenty of space, as I hope to evolve my simple character maps to animations. I am also quite new to thi ...

Thank you Ttelmah, for your quick and courteous response. I will add an EEPROM to my circuit and continue from there.
Regards,
David

Hi,
I am trying to interface my pic16f877a with a knockoff nokia LCD. I have had success with everything except displaying characters, text, or bmp files, simply because it requires you to link to ...
