PE : BitsIo and ByteIo

[sebikoo]

Hi.

I am writing code with PE on CW4.5

When I use bitsIO for Port 8ch, I get warning msg saying that " It is better to use ByteIo instead of BitsIo."

I need to handle each bits used for output, thus I choose BitsIo.



What if I use ByteIo? Still I can handle each IO like BitsIo?

What is difference between BitsIo bean and ByteIo?

Hello,

ByteIO bean provides the same set of methods like BitsIO bean. You can handle each IO pin by ByteIO bean as well as in BitsIO bean.

Generally if you need to handle a whole port (8-bit input/output) it is recommended to select ByteIO bean instead of BitsIO bean and it is recommended to select the BitsIO bean for utilization as a two- to seven-bit input/output. ByteIO bean has more optimized code of some methods than BitsIO bean when using for whole 8 pin port.
