    Re map/assign ports

    Hi I have seen a thread some time back but cannot find it, can someone point me in the right direction please. It's about combining 2 ports or parts of ports together so it is easier to program. An example: If I have B.1, B.2, B.3, B.4, B.5, C.5, C.6, C.7 How do I set them up so it's as if...

    28x2 chip variants

    Hi, I have a couple of 28x2 chips that I purchased from rev-ed about 18 month ago and they are labeled as "PIC18F25K20", I notice that the 28x2's are now labeled "PIC18F25K22. Does anyone know what the real difference is between these two chip? I assume very little, just wondering. Thanks

    DS3232 Question

    Hi All, I would just like to get confirmation on what I am doing is correct before going any further. Attached is a typical circuit for the DS3232 RTC and my circuit for the 28x2. My question is: Am I correct if I connect the reset from the DS3232 to the 28x2 that has a pullup resistor and a...

    Question on program syntax

    Hi, I have a project that uses a small 12v pump to pump water and a float to detect the water level, when the water reaches a certain level the float closes the contacts and the pump starts. My very basic program works, but the syntax doesn't seem to be consistent, I am open to any suggestions...

    Logic level

    Hi all, I know I have either read this (logic level) in the manual or on a past thread, but I cannot find it again (or remember the answer). I would like to know what the voltage range is on a Picaxe (28x2) when it will detect a high, and while I'm at it, what a low is? I had a feeling for a...

    Interrupt question

    Hi All, I’m trying to understand the interrupt command I’m getting a little confused with some of the examples in the manual. In Section 1 on page 81 (v7.0) in the example it states that it will: “activate an interrupt when pinC.7 goes high” (as far as I can see there are no pinc.7 that is a...

    FRM010 - LCD - serout problem

    Hi all, I am having trouble communicating with a 16x2 line LCD using the FRM010 chip and the Picaxe 08m. I have searched the forum and found some helpful ideas but I’m still unable to find the problem. I don’t know if it the circuit or the code I am sending. The LCD is one just like this, it's...
