Hello everybody,
Today I tried this sample: 16f876a_sht.jal.
At the beginning I only saw the first and the third line of my the
20x4 lcd.
In order to solve this problem, I had to modify, lcd_hd44780_4.jal,
with the two lines below:
__lcd_write( 0b_0010_1000 ) -- two lines, 5x7
delay_10us(4) -- > 37 us
respectfully,
Enzo SERAFINI

procedure lcd_init() is
-- first, init the interface
lcd_rs = LOW -- set to control char
mode
delay_1ms(25) -- power-up delay (>
15 ms)
__lcd_write_nibble(0b0000_0011) -- function set
delay_1ms(5) -- > 4.1 milliseconds
__lcd_write_nibble(0b0000_0011) -- function set
delay_10us(10) -- > 100 us
__lcd_write_nibble(0b0000_0011) -- function set
delay_10us(4) -- > 37 us
__lcd_write_nibble(0b0000_0010) -- to 4-bit mode
delay_10us(4) -- > 37 us
__lcd_write( 0b_0010_1000 ) -- two lines, 5x7 (line
added by seen)
delay_10us(4) -- > 37 us
-- init the API
_hd44780_init()
end procedure
