Hi all

got that sensor for a while an I taught it would be nice to plug and play with it, but it's not behaving nice to me so far.

After a long read of the spec sheet, I came up with the following code
Code:
'I2C data communication with HP01D, low cost pressure/temp sensor
;i2Dpin var PORTB.7
;i2CLKpin var PORTB.6
; HP01Pres var WORD
; HP01Temp var WORD

; ******* READING PRESSURE *************************************************


  I2CWRITE i2Dpin,i2CLKpin,$EE,$FF,[$F0]  ; resquest pressure reading from sensor
  ; $EE is WRITE command to the HP01D
  ; $FF is address to write in
  ; $F0 is to read Pressure  , $E8 is to read temp 

  pause 38  ; at least 38ms is required before we can read the data

  I2CWRITE i2Dpin,i2CLKpin,$EE,$FD     ; set sensor for retrieve result
  ; $EE is WRITE command to the HP01D
  ; $FD set sensor to read?

,
  I2CREAD i2Dpin,i2CLKpin,$EF,[HP01Pres.highbyte,HP01Pres.lowbyte],NoREADAck   ; Read values
  ; $EF is READ command to the HP01D
taugh it was pretty slick, but It does not work at all

I think there might be a problem at line
I2CWRITE i2Dpin,i2CLKpin,$EE,$FD ; set sensor for retrieve result

because i'm not sending any data? But that's the way the sensor wants it...
can shiftout do a trick here?

I also tried with I2C_SLOW setting, but no data comes out
