dsPIC30F5013 Switch ReadState Bug

[ronaldlijs]

Hi guys,

Using Flowcode dsPIC 5.5.2.1.

Simples I get the following when compiling my little project (SWICTH0 on PORTG_H_0 and LED0 on PORTB_H_1), anmd the program doesn't run on hardware.

test.c: In function 'FCD_SWITCH0_WaitUntilHigh':
test.c:304: warning: comparison is always true due to limited range of data type
test.c: In function 'FCD_SWITCH0_WaitUntilLow':
test.c:333: warning: large integer implicitly truncated to unsigned type
test.c:342: warning: comparison is always false due to limited range of data type
test.c: At top level:
test.c:293: warning: 'FCD_SWITCH0_WaitUntilHigh' defined but not used
test.c:331: warning: 'FCD_SWITCH0_WaitUntilLow' defined but not used

Compilation successful!
Return code = 0

Seems like a bug to me... and Flowcode won't read the status of PORTG_H_0 on hardware, I have chcked with the Flowcode debugger).

If I use an "Input" component in Flowcode to read PORTG_H_0, the program works fine.

Below the little program working and the one not working at all.

Thanks for looking into this!

This is an issue for all processors with 16 bit ports. The switch component tries to read a 16 bit value into an 8 bit variable. Drop the attached file in the components directory to solve the issue.
