Good morning,
i have problems with the calibration of the touch screen uLCD43PT using the software "ART1020_touch_calibration" and therefore i read the data sheet of the AR1020 and the software uesd for the calibration.
Since the I2C bus is used, the AR1020 uses the signal SDO to communicate when it is "ready" (pin 6 SIQ is not read from Picaso) which becomes the signal "CT_INT" (page 22 of schematic uLCD43).
This signal is connected to pin 48 of Picaso GFX2, while the file "AR1020.inc" refers to pin 16:
*
* constant SIQ_PIN # 16 / / pin definition for AR1020 SIQ pin (HI When data ready)
* while (pin_Read (SIQ_PIN) == 0) / / wait for device ready
*
*
the pin 16 is the data D0 for the Picaso GFX2.
It 'correct??
