| V0.82b-Arthur-P 2010-12-18 |
| ------------------------------------------------------------------------------------------------------------------ |
| Version includes only support for external HEF4017 for FC1.x hardware, NOT for Twi2Ppm converters for ESCs. |
| |
| 2010-12-18 Transferred changes to v.0.82b-Arthur-P |
| 20100917: Transferred changes to v0.80g-Arthur-P. |
| Arthur P. Modified to use several parameters for servo control: |
| User_Parameter4: |
| User_Parameter5: |
| User_Parameter6: |
| User_Parameter7: |
| User_Parameter8: Use external HEF4017 if bit 8 is set (>127). The remaining 7 bits are used |
| for the shutter cycle counter: the value is multiplied by 5 programmatically, |
| resulting in steps of approx. 0.1sec. Minimum value to start using the |
| interval timer is 10 (approx. 1 sec, or countervalue of 50). Note that this |
| was originally done through user para 6. |
