Trying to check port bits, compiles, doesn't work...FIXED

[woodfold]

Complete newbie here.
I've gotten this code to compile, but it never stops when the bit is set high. Can anyone point out my error?

Code: Select all

program LCD_Test
dim text as char[20]
main:
  DDRB=$00
  Lcd_Init(PORTA,3,2,PORTA,LCD_HI_NIBBLE)
  Lcd_Cmd(LCD_CURSOR_OFF)
  text= "TEST"
  Lcd_Out(1,1,text)
  while true
  PORTB.7 = 0
  Delay_ms(1000)
  Lcd_Cmd(LCD_SHIFT_RIGHT)
  wend
  end.

Turns out PORTB isn't the correct usage.
Here's what did work:

Code: Select all

program LCD_Test
dim text as char[20]
main:
  Lcd_Init(PORTA,3,2,PORTA,LCD_HI_NIBBLE)
  Lcd_Cmd(LCD_CURSOR_OFF)
  text= "TEST"
  Lcd_Out(1,1,text)
  while PINB.7=0 then
  Delay_ms(1000)
  Lcd_Cmd(LCD_SHIFT_RIGHT)
  wend
  end.
