I tried the the new print command for long integers,but it doesn't work for me on ATtiny2313 + LCD. After some investigation i found out, that arithmetics give strange results with long and integer-variables. Tried with another AVR (Mega48) and serial communication and got the same issue.
This code works proper on PIC (with differences for the first lines of course) but with different results on AVR:
'ATmega48:
#chip mega48, 1
'Configuring UART:
#define USART_BAUD_RATE 1200
#define USART_BLOCKING
Dir PORTD.1 Out
Dim lVar as Long
Dim iVar as Integer
'Testing LONG arithmetics:
HSerSend 13
lVar = 22222 / 2
HSerPrint [word]lVar 'should give 11111, o.k.
HSerSend 13
lVar = lVar * 2
HSerPrint [word]lVar 'should give 22222, o.k.
HSerSend 13
lVar = lVar / 2
HSerPrint [word]lVar 'should give 11111, but gives 0
HSerSend 13
lVar = 12345
lVar = lVar % 1000
HSerPrint [word]lVar 'should give 345, but gives 255
HSerSend 13
'Testing INTEGER arithmetics:
HSerSend 13
iVar = 22222 / 2
HSerPrint iVar 'should give 11111, o.k.
HSerSend 13
iVar = iVar * 2
HSerPrint iVar 'should give 22222, but gives -23601
HSerSend 13
iVar = 22222
iVar = iVar / 2
HSerPrint iVar 'should give 11111, but gives 1
HSerSend 13
iVar = 12345
iVar = iVar % 1000
HSerPrint iVar 'should give 345, but gives 12345
HSerSend 13
wait 200 ms
End
