If you use a reasonably modern optimising C compiler the resulting code will often be the same if you use a #define for Sq or a function.

(Because they inline short functions when optimising for speed.)

Macros can be useful but can also make it very hard for other people to read your code - and the error messages the compiler makes when they are involved are sometimes not very helpful.

You have been quiet for a long time. MIssed your voice. Hopefully health and heart are staying on the green side of the grass.

I have not played with these types of displays for many decades.

Nice update Chris.

I have changed my approach. To the design of how it's design to get this beast to function, this will be accomplished by using 2 Ardunio. Vegas one just to run the display since there's as i have a mix of alpha & 7 seg displays, I have to use 16 bit gpio and run the. statically.
The second cpu handles quite alt
A. Transmitting am receiving messages from the cam bus
B. keeping track of which display it needs to us
B. Encoding the keyboard and 4 other switched.
D.. TALKING the other cpu two items 1
1. The ascii letter /number
2. Which display

Oh yes you need to run incandescent things at 4 volts to boot

.so currently that's 3 boxes

CP-1252 the computer display. And keyboards and switches.

There will be an i interface box which cxu termination between echo boxes

last there is the.LRU which talks to the can . And the Sim itself.

I found the PIC18F26k80 paired with a MCP2551 (now NRND) was a great way to get familiar with CAN bus, Microchip have lots of documentation such as their ECAN application note (as the 26k80 has an onboard ECAN module) and C library's, very easy to implement once you have got an idea of the CAN bus concepts.

Nice update Chris.

Takes me back to days when I did CNI avionics analysis.

C++ has the very same constructs. Exceptions, Invokable, same thread support... .Love java, but this comparison is odd.

Would you be so kind to share your Arduino code?

Hi, would you share your Arduino code?

Sorry to hear that. Edge protection is vital.

Backup, Backup, Backup with regularly properly tested recovery procedures is one of my mottos!

One of my systems died and with today's multichannel PCI-e channel storage (in disbelief) I was able to recover 110+GBytes and be back up online within 10 minutes.

Damned amazing. - However if it can be recovered that quickly imagine how fast it can be trashed!

Cheers to all!

Yes, everything is great until it is not.

I can sympathize, rebuilding your system can be a major pain.

Whoa, this takes me back to the early 1980's when I was controlling Syncros for a FLIR using radar information.

They were very responsive so I had to build software to slow them down so the user had time to assess what was going on.
