Alan thanks for that explanation of the architecture, it's a lot clearer than my experimentally derived picture! With apologies, the difference between the programmed and displayed string is a red herring. I wrote the post over a couple of days ago and played with the code in the meantime...

The problem with this faulty display is that it doesn't respond normally to either 254, 128 or 254,192, in either case short text strings don't appear in the display area. Adding 254,2 to the start of the code forces the display to start at row 1 position 1 each time it runs, without having to...

Thanks for the suggestions. As it was raining the other day I decided to waste some time trying to get to the bottom of what's going in with the display. Reloading and power cycling the display seems to have got rid of the odd characters in start up, so we can forget that issue. However...

Thanks for all the replies. I had already done as Inglewoodpete suggested, several times in fact, but as recommended I did it again using a new download of the 18M2 code. I didn't mention that I previously replaced the 18M2, just in case. I can't see why there should be a difference but the...

I have an AX133 16 x 2 OLED display that has gone faulty and wondered if there is a way of resetting it. As far as I know I haven't 'done' anything to it to cause the problem and it had been working fine for several months before this happened. At switch on, for a very brief instant the top...

I had to leave this project to one side for a while but am back on it now. Thanks for the replies. The suggestion to use the lookup function is definitely more sensible than using a separate hserout command for each character and works well, albeit it does need a 10mS minimum pause to avoid...

Thanks for the quick replies. I've read a few of your posts on this and other topics Alan and they've been really helpful. Breaking up the strings, including the control codes, certainly works but is going to be mighty tedious to implement on the final program for longer variable strings...

Hi I am writing a program that uses the Time variable and found it to be slow as a result of using serout to send data to an axe133 OLED display. Other posts on the Time/serout issue state that using the hserout hardware port avoids this problem. My simple test program using serout works...

Thanks for comments. I guess I'll be buying some 20M2 chips. Paul

I want to use an 18M2 ADC and improve the measurement accuracy with an external 1% reference 4.096V voltage source. The Picaxe manual 2 p.31 states that the Vref+ input is n/a for the 18M2, only Vref-, however the datasheet for the PIC16F1847 shows that both are available on the original Pic...

I've just updated Program Editor 6 to version 6.0.9.3 and I no longer have variable labels in the code explorer window, just their values. Where have they gone as they're all but essential to make sense of what's going on. I've probably done something dumb by I can't see what. Thanks Paul

I have a project that uses the 1307 chip to provide reasonably accurate time. I want to be able to alter the time setting from the main program and have a routine that reads the individual clock parameters, any of which, after being converted from BCD to decimal, can be incremented/decremented...

Screen shot of settings above, hopefully.

For some reason my pc decided to seize up today whilst working on a project and before I had saved my latest software version. 'Never mind' I thought, it's backed up automatically, however, when I went to the backup folder, the last backup for any project was at 23:40hrs on 31st December 2015...

I am using a count gosub routine with a 124mS period in a do - loop program with a number of other sequential gosubs within the loop. This all works fine until I add an elapsed time gosub routine to the loop that uses 'time' to count the number of minutes that the program has been running. A...
