I2C waveform Strange
Ok i have got it sorry. The instruction address for DDRAM is 10000000. The position for the cursor is written in that instruction. e.g. For the start of each line (...

Ok i have figured out what is wrong with line two not working! It seems i have been writing to the wrong address (For line one & line two). There seems to be something extra...

Brian: Wow yours does it too! So it seems as though its part of the displays average design. If you have a initialization & how you write to the second line then that would be...

Ok Here is both. Sorry to be such a pain. This writes DATA to the screen. Device+RW RS Data Start 01111100 A 01000000 A 01001000 A Stop In the above i have just...

Quote: I can see The above was when i was reading the busy flag so don't really trust that. I can do a simple print like (Start "H" Stop) & post the picture here if you want.

KitCarlson Yes i would agree. It tries to pull the 3.3v rail to ground but it cant because "the device" impedance isn't low enough. Therefore you get that small...

Yeah it would be good if i had one of those lying around but i have this... Darn. Sorry i forgot to include more information at the start. Yep there is no point in looking at the...

Just for someone else reading this post in future it looks like you cant read the busy flag with the I2C interface anyway because i found this stuffed away in the datasheet Quote...

Ill see if can get my old analog scope going but it was rubbish last time i used it. I found the reason for the missing character & it was not enough delay after a screen...

Frequency is 100khz. Its running at 3.3volts. Yes its using TWI hardware. Ah ok i was wondering why anybody else's code was looking at wasn't looking at the busy flag....

Excellent work Kas! I had been looking on the net for pictures that could resemble what would be in this box. I have found pictures that you supplied in the link but it seemed...

I tired to make my own code to begin with but i didn't go far with it when i found out i was re inventing the wheel. Peter Fleury has I2C etc library's for what you want to do....
