BH1750FVI sample code available?

You ought to be sending this way

not in my view
addr var byte
addr= $46
i2cwrite sda,sck,addr,[opecode]
i2cread sda,sck,addr,[dat.highbyte,dat.lowbyte]

Big thanks Richard! now it works!

here's the code:

adr=$46
x=0
cnt=%0100011
i2cwrite ldta, lclk, adr, cnt
pause 200
cnt=%00010001
i2cwrite ldta, lclk, adr, cnt 
pause 200
maik:
cnt=%00010001
i2cwrite ldta, lclk, adr, cnt 
pause 200
cnt=%0100011
i2cread ldta, lclk, adr, [x.highbyte, x.lowbyte] 
pause 200
lcdout $fe, $1, dec x
pause 200
goto maik

Big thanks Richard! now it works!

as maybe but you are still incorrect , if you use a logic analyzer you will see the transaction ends abnormally



wrong way
i2cwrite ldta, lclk, adr, cnt
correct way
i2cwrite ldta, lclk, adr, [ cnt ]

Well, just added these square brackets - see no difference in readings.

its best to be correct for future reference , not all i2c devices are so forgiving
