LED was very dim when using bitlash

[rmd13]

Hi, I use bitlash and send a command:

d7=1 * turn on pin 7
The D7 pin was connected to LED, but I found the LED was very dim.

Then I run arduino IED and upload the sample Blink to test if arduino is OK,I found that the LED was bright as normal.

It's weired. Can anyone help me, thanks.

Ah ,I solved it.

I just add one line:
pinmode(7,1)
then LED was bright as normal.
