Bugs in ARM basic functions.

[ARM]

Hello,

I want to report the following bugs:


----- 1. Error in compiler -----

Device: ARM.AT91SAM7S.AT91SAM7S512_64
Generated by: Flowcode v6.1.2.0
.....
Flowcode HMI-Control 2.c: In function 'FCD_047b1_RS232__SendString':
Flowcode HMI-Control 2.c:213: warning: pointer targets in passing argument 1 of 'FCI_GETLENGTH' differ in signedness
Compilation successful!
Completed compilation, return = 0

all other files are compiled correctly.


----- 2. Error in external interrupt -----
see also Project HMI-Control in attachment.

Flowcode HMI-Control 2.fcfx

(18.92 KiB) Downloaded 182 times

Interrupt pin INT1 and INT0 deosn´t work (INT0 is peripheral B. When it doesn´t work it is OK, because it is very tricky to switch cyclic from peripheral A to peripheral B in running program)

serial Com to edip touch display is OK. But when i did enable INT1-pin the interrupt doesn´t work.

What I see:
When Flowcode Program in µP is starting without enable interrupt, PA16 is flashing once for a short time.
When Flowcode Program in µP is starting with external Interrupt 1 enabled, PA16 is flashing once and after a few second once again and then the Program is first starting.


----- 3. Error in output makro -----
When I set output port (complete port) to 0 it is ok.
When I set output ort (complete port) to 1 only bit0 of the port is set to 1. The other port are still 0.



kind regards

Hello,

Thanks for letting us know about the problems you are facing.

1) This looks to be a warning rather than an error. You should be able to ignore it and the program should still function correctly.

2) I have answered this for you on the other thread you created.

3) When you output to a complete port then it writes the binary value to the port register. Writing the value of 1 I would expect only bit 0 to switch on as 1 in binary is 0b00000001. Try writing 255 to the port to get all 8-bits set.
