How to connect the 4x3 keypad to a pic using the kbd.c, the code does not say which i/o is for the column or for the row.
Thanks. |

Search the forum for kbd.c and you will find many posts on the subject asking the same question you are.
It is best to do a little re(search) in this forum before asking a question. A lot of questions have been asked (and answered) many times before. It saves a lot of time for everyone (including you) because reading the threads will gives you a wealth of information beyond just the connections. This way folks on the board don't end up answering the inevitable followup questions that have already been addressed. |

Searched them and no answer regarding connections. |
