AsynchroSerial component headaches with KL46Z

russellsher — Sat, 09 May 2015 17:45:06 GMT

I am using the KL46Z board:

If I send characters such as:

AS1_SendChar(‘a’);

AS1_SendChar(‘b’);

Only the ‘a’ was sent…

Then I realized that if I include a delay between sending, then it worked.

After that I enabled interrupts to use AS1_SendBlock

If I then do any uart function – either AS1_SendChar or AS1_SendBlock

The program sends one character and then hangs.

By the way - how (and when) would you use AS1_Enable();

I get 'undefined reference' to it (with interrupts enabled for ASerialLdd1)

(I still cannot enter debug mode at all and can only drop and drag to the folder to run code.)

Hello,

if you receive a 'undefined reference' from the linker, this means that this method/function does not exist. Make sure you toggle enable/disable the function.

The 'x' in the Icon means the function is disabled (not generated).

Then do not forget to generate code.

Hi and thanks Erich - Yes I see this now (I also posted a further comment to my last post on your site -- I think things are becoming clearer)

I used a serial example from Jing which works fine -- I think I don't have good understanding of the difference between Asyncroserial and Serial_LDD

I guess my enabling interrupts resulted in a vector unknown territory with Asyncroserial. Do you use this routine? Perhaps have some code to share on your site - in particular withKL46Z

best regards

Hi Russel,

there are already several examples on GitHub here:

mcuoneclipse/Examples/FRDM-KL46Z at master · GitHub (CodeWarrior, but settings are for KDS applicable too).

mcuoneclipse/Examples/KDS/FRDM-KL46Z at master · GitHub (KDS)

Thanks Erich, I'll have a look.
