Does Bob have an Embedded page?

Maybe this is what you are looking for: CodeProject Stuff[^]
Ok I deserved that.

I think the question is about where to post a question about embedded systems... :sigh:

Well in all fairness I need to ask a question on C programming to make sure I am not missing something. I was in the middle of writing a document (not related) and thought :bob: might know. So in all fairness I deserved the trolling.

Richard, Richard. I don't think I've seen you troll anyone before. :-D

Hi All, Do we have an Embedded page or shall I ask in C/C++ forum..? Glenn.
Try pinging honey the codewitch directly, probability is she'd be the only one to answer anyway :D

Well, pardon me for trying. The title of the question led me to believe that Glenn is looking to embed a pictire of Bob somewhere.
He did wonder if should post in the C/C++ forum, hence my conclusion.

Nope, I know our little Green friend! I remember see stuffed Bob's somewhere... has he been licensed?

If it is more about the hardware part - you should go here: https://www.codeproject.com/Forums/186301/Hardware-Devices Otherwise go with the programming language you use...

Nope, solved it myself, posted the question and face palm came up with a solution...

I fixed it, wrote the question though about it and solved it about two seconds after I posted it, tried it, Working all is good!

I do IoT stuff, which is related and similar, and am diving into more embedded here. For my part, I just ask C questions in the C section, whether it's embedded or not. What's harder is asking about the things where the hardware and firmware meet, but typically I'll just consider that a programming question, tag it as best I can, and then make sure I'm clear about what I'm doing in the description. There are enough embedded devs here I think you'll be able to cast a net and get something that way.

Anyway, MS is coming out with a G5 ARM Surface Go; and VS can generate ARM code ...

Not to worry I solved the original problem and as is the case meant something else broke, bodged that. Now being left over night to see what breaks next... The LCD driver is a pain yes, you can send it an integer or float but will display a decimal point? Some times yes some times no, and will it return I2C address? (so I can hook up a real time clock that use I2C) No is the answer. Shall I try to get the data sheet, oh company went bust and some genius bought a load of LCD's on Ebay... :rolleyes: Circuit diagrams, who needs those! Glenn (I need :beer:)

You're probably using a crappy graphics driver. I have one that may work better for you depending on the type of MCU you're using, but your best bet is to actually use sprintf(tmp,"formatspecifier",value); and then display tmp so you have total control over the formatting of it.

Graphics Driver I wish, No RTOS a while(1) or a for(;;)...

sprintf(tmp,"formatspecifier",value);
I would have to load stdio for sprintf()... no room. Think it's the I2C having a bit of noise. Will play more tomorrow. Thanks Glenn

I meant the library you're using to communicate to your I2C or SPI display. Clearly, I don't know enough about your platform. It might be simpler to just roll your own ftoa type function

Interesting...get the scope on the pins lots of noise I think the fault is with the board, I'm gonna start probing... Also know of a good I2C reference... ;)

Check the values of the pullup resistors. Too low and the drivers can't sink the current. Too high and they can't deal with the capacitance of the wires (sounds like you must have wires to an off-board display). You might try twisting wires, too, thought that's more to keep radiated noise out of other circuits.
