So the 4.x optimisations are mixed in with the old 3.2 stuff? Sigh.. I'm currently using teensy 1.59 & the 1.8.19 IDE for writing this stuff. I'd figured I was back far enough. Guess not. I totally understand why you are not interested in...

Well, this doesn't even use the Serial stuff. And it has the error. So this can't be right. void setup() { float x = atof("4.3"); } void loop() { }...

It's not the warning I'm worried about. It's the compile error below the warning.

Randomly getting this error message. (Yes randomly, changing random things in the source causes it to come and go.) Here's the error...

Yes, I know. But in this case I have no say in the matter. Some are specced for int32_t and some are insisting on int64_t. I notice that the instruments that I'm using to display the values (marine applications) are using the int32_t versions of...

Like I said it was late and I was tired. Just because the function is declared in the .h file doesn't mean I don't need to actually write it in the .cpp file. Thanks again for the help. What you were all telling me pointed me in the right...

What's going on. This is converting GPS data (read in as text string) to NMEA2000 data packet. (binary) They are looking for latitude/longitude in degrees. Then multiplied by 10^16 and stuffing the result into a signed 64 bit integer. Kinda'...

Ok got one more issue.. int64_t the compiler thinks its a "long long" ? How can I bailing-wire together an int64_t? Is it even possible?

Well, the speed should be fine for this. I only need to calculate it twice per second. As for the 4.x teensy? I'm getting there. I only have about 1/2 dozen 3.2 teensy's left. Then I will be switching over. P.S. Thanks for letting me know the...

Thank you!

Actually, I see that it's listed as 32 bit processor. Do I need to use double to get the precision? I have some picky math in my immediate future. -jim lee

Does it do 32 bit math operations? Or just 16 bit? I think Arduinos typically only do the 16 bit stuff. Many thanks! -jim lee

Wait, I tried switching it over to serial3, nothing. So I removed the added serial device all together. Nothing. I'm sorry to have bothered you guys. I obviously have something else going on here. Maybe I cooked one of the SPI pins messing about...

Thanks. But that isn't working either. I have pin 7 free and I can move move pin 8's wire to pin 6. This'll leave Serial3 free of anything. I think I'll try that for now. -jim lee

That still seems to get in the way of the SPI port. (That likes to use pins 9 & 10 as chip select) Or maybe I'm doing it wrong? Serial2.setRX(26); Serial2.setTX(31); Serial2.begin(9600); -jim lee

The pinout picture shows Serial2 can be 10 & 9 -or- 26 & 31. How can I select the 26 &31 set as opposed to the 9 & 10 set? Thanks! -jim lee
