[MB 6.0] timing problems with DS1820 example

[bruno]

Hello,

DS1820 example (PIC18F452, EP4) should be corrected like this :

Code: Select all

   while TRUE
     Ow_Reset(PORTA, 5)             ' onewire reset signal
     Ow_Write(PORTA, 5, $CC)        ' issue command to DS1820
     Ow_Write(PORTA, 5, $44)        ' issue command to DS1820
     Delay_ms(750)              ' <==============here
     i = Ow_Reset(PORTA, 5)
     Ow_Write(PORTA, 5, $CC)        ' issue command to DS1820
     Ow_Write(PORTA, 5, $BE)        ' issue command to DS1820
     Delay_us(120)                ' <================here

     j1 = Ow_Read(PORTA, 5)         ' get result
     j2 = Ow_Read(PORTA, 5)         ' get result (assuming the temperature 
is positive)

(same for C example, did not check Pascal)

also, sensor with mB is on RA5, and with mC on RE2
