Might be worth steering clear then and buying a nextion display when I need to.

Been reading bits on the Nextion display and watching videos on youtube as you do, have known about the nextion display for a while but happened to stumble across Stone HMI's, similar setup to the Nextion as in has a PC editor for making the GUI up and a serial connection. Has anyone used them...

This works in the PE6 simulator as an idea of turning a bit on and off from a picaxe input, this being part of b0 would the be sent to the MCP23017 and in theory output A0 would turn on. if pinB.6 = 1 then let bit0 = 1 else let bit0 = 0 endif I didn't think it would be that easy haha...

Hi, question about the code I've written below. It sets up two MCP23017's to be all outputs. I've used b0 to b3 so that I can use the "bits" in my program as if you would an output on a picaxe it's self, so instead of say High C.7 I can do High MCP1_A0 (bit0 of b0) which gets sent to the first...

Morning chaps, thanks for your replies to the thread, I will have a read through the posted links. I wasn't looking at anything as complicated as analogue expansion (not yet anyway) just digital I/O. I was thinking that my 12 ish relays might be nicer fed from some sort of I/O expansion chip...

Just been having a route about the forum and the picaxe website in the FAQ section and just wondered what fellow forumers (if that's a word) thoughts are on adding I/O. There are the following options from what I can see:- 1. Use a bigger picaxe chip (probably the easiest thing to do) 2...

Nice explanation, thanks Alan.

Out of interest Alan what would be a more byte friendly way of doing the BINTOASCII command and why does the compiler use 40 bytes?

Agreed on all levels, I wouldn't have learned what I have without the efforts of these people.

Possibly last version of the code, this one unlike 3V0 above is tested and works, it's time I moved onto the next part. I've answered my own question in #35

Blimey, re-coded by a master I see, I will compare my attempt with yours to see how you've done it. Thanks again to all who have helped with this and glad you've enjoyed the challenge of shrinking it down to fit on legacy hardware Alan, I hope to learn more from your work. If starting at the top...

Evening chaps, The attached isn't tested as yet as I'm away from the test hardware but the attached does compile, fits on a 14M2 and uses no system words. I've ended up using w0 (I head left this one unused to start with as suggested..but) as a common us variable, I use this to receive the data...

So what your saying is that if you poked 0 you'd be writing to w0 and poke 27 would be b27 of w13 these are the only ones you have direct easy access to the WORDS, BYTES & BITS of from then on up to whatever the limit is you have to poke to and then have one of the lower accessible ones to peek...

Hi, This is neat I was then going to ask about the fact that the sensor fail comes from the CJ_VAL (Cold Raw) for each sensor, how can I still use the bx from each one if I use the same Wx for each sensor, it will just have the value of the last one written to init? Don't worry about the...

Been through the code again which I've attached and as you can see I've had to go back up to my 20X2 even with taking things like the output Deg Celsius down to Bytes instead of using up Words I'm still over the overall word count for a 14M2 and now I'm not using words for the temperatures, if...

Morning chaps (where I am anyway) thanks for looking and being constructive in the criticism, it's very helpful in the learning. Your right I didn't but now I've seen what you've done I will as get what you mean.

I've managed to get the code to now fit on a 14M2 by using ll the system words where I don't need to have access to the words bytes/bits and it works fine. I looked into the use of poke/peek and couldn't work out how I could make it work and save on using the normal variables to read from and...

Thank you both I'll spend a bit of time looking into seeing if I can modify my code to use RAM where possible and save the words for those that need them.

With the use of the system words on an M2 (SW_0 to 7) can you access the bytes & bits of these words?
