Got it!!!!!
Hi: I think I might have created an unwanted post on your forum. Please check and delete. It might just be blank. I'll have a look in a minute. Ok. I have the display working from my Arduino. The main issue was in my code in that I was always sending the 0xFE. That of course put the display in comma...

Hi Raquel: Changing the address to 50 made no difference. Unfortunately it does make me question the value of the Diolan U2C-I2 I have been relying on. I expected that the device reported the addresses it saw on the bus. Originally it indicated 7F which I took to be the Arduino and 0x28 which I beli...

Good Morning Troy: Thanks for your suggestions. I will give those a go and report back. The begin.Transmission function is supposed to do the actions to start I2C. I believe that is the transition of SDA from high to low. I don't think they do anything more than that. I am concerned only in that I h...

Hi: Still no luck. I discovered this morning that I2C on the Arduino uses Analog Pin4 and Pin5. All day yesterday I was using Digital Pin4 and Pin5. That was a pretty good waste of time. Today I am on the right pins. I also connected my Diolan monitor to the SDA and SCL pins on the display itself. I...

Hi Troy: Still no magic, but I am updating a library for the Arduino that will hopefully get me where I need to get. I know I did all the code at the low level the last time, so I hope the library will be quicker in the end. When done, would you like copies of the .h, .cpp and Arduino sketch? Your a...

** Not a Matrix Issue - User Problem - Code **
Hi Troy: Thanks for your reply. This morning I found my previous post on this forum from some time ago when I first got this display. In reading that post, I was reminded about 7 bit vs 8 bit I2C addresses. On that basis, the actual address for this display is 0x28. I hooked up a device I bought som...

MOI-AL-202 with XBoard I2C help request
Hi: I am trying to get this combination to work with my Arduino Diecimila. I am not expecting you to help me on the Arduino side, but it has been some time since I have worked with this display and I suspect that I am doing something wrong. I am looking in the MOX.pdf manual and on Page 14 it indica...

Hi Raquel: Thanks for your note. I appreciate the code. That is most kind of you. Can I use Large characters and regular characters at the same time? It would be nice to have 4 large characters for the numbers for the clock on half the display and then regular text for date and day of the week and a...

Hi Troy: I guess what I was looking for was a little more detailed on the pixel level. For example, when writing 5x8 characters, there is a space between the characters. I am assuming that there are no active pixels in this space. I would similarily assume that there are no active pixels between the...

Hi Troy Lets drop this thread and stick with the AL202 since I have temporarily shelved the 404C It is entirely possible that there is enough space available for me on the AL202 to do what I would like. I did read something about reserving bank 0 for the splash screen. If I don't want a splash scree...

Thanks Troy: I am certainly interested in the advanced font kind of stuff. If I could fake a split screen to get full size characters I would be most pleased. I did put it on hold for the weekend to focus on getting everything running before I started playing around. Saturday was very frustrating as...

Hi Troy: Amazing things happen when you use the correct address. My display is working perfectly and all I changed were two characters. I'm still kicking myself. Perhaps you might have some advise on the subject of characters. Ideally, I would like to used the left half of the display in medium mode...

Ray: Thank you so much for the Arduino link. I have been going through the site in detail as I was working on try to get a parallel display up before I switched to this new display. I tried both the 4bit and 8bit libraries. The 4 bit worked and I got garbage. The 8bit worked great but I really wante...
