The strange behavior of the compiler MB for PIC32

[montana_rus]

Good day !

Some days ago I detected the strange behavior of the compiler MikroBasik PIC32. I thought that is accident. But the problem shown more often. Problem is next:
First, the program after compiling for PIC32MX795 worked correct. Then it was need for some changes... For example, it was code:
.....
UART1_WRITE_TEXT ("Press any key")
i=i+1
.....
After addition a code for a view:
.....
UART1_WRITE_TEXT ("Press any key")
UART_WRITE_TEXT ("and work will done !") ' <---- this line
i=i+1
.....
in the working process of program body the strange take place: failure datas, incorrect rinning routines and more-more... This strange is shown also if change places two routines (procedure of functions) just. The compiler not gives error, it's OK, but really the program behaves unpredictably.
Please , need answer abour specific for PIC32 MikroBasik Compiler: is need any requirements for a lenght of routines (procedure, functions).

Thanks
Best regards,
Aleksey

Hello,

since this is the same topic, I had answered you to the other one, so we can continue the conversation there:

Hi Aleksey,
Before using Uart_... (so without number x) one must select the uart to do the action on. This is done with UART_Set_Active. See the compiler help for details.

Remark1: After a Uartx_Init (or Uartx_Init_Advanced) (with the uart number x) a Uart_Set_Active is done implicitely to the Uartx initialised. This means that, if you e.g. only initialise and use Uart1, you do not need to do Uart_Set_Active.

Remark2: when using Uart_... routines will link all uartx routines to your code next to the code of Uart_... you use.

So, perhaps you need to do a Uart_Set_Active ?

Hello Aleksey,

can you explain your project here? Use only one topic please.

There seems to be some issue with the tickets you are sending?

Dany has a good advice in case you didn't use that function. But it would be great if you could attach the whole project just to avoid the assumptions.

Kind regards,
Biljana
