Would you mind sharing the PBP code for the hex file you've already shared?

Why not! I need to comment it before. Give me few days.

Hi, guys....well let me describe better what the needs are, i have 2 PWM servo outputs, each one is driving each servo from left to right,..., with a 5V TTL logic level, movement from left to right is changing the pulse width from 1ms to 2ms, with 1.5ms at center position,....the movement is like 0....to...60 degrees minimum angle, or a maximum 90 degress !

Thanks

Hi again, my problem is that i would like to use it but needs modifications and we only have de Hex code, so if you could do it for me that would nice, of course with the necessary cash amount for your work, if you wish so !

thanks

Attached the PBP files in txt format. If you need to add more code then you have to change pic.
Suggesting pic 16f628 which has the same pinout but 4K of memory. In this case you have to add these two instructions at very top of the code.

Code:

CMCON   = 7
VRCON   = 0

This version is the latest so if you have in use the previous one replace it, with this one.
More torque, better homing and high precision also with 1 single step travel command.

Enjoy.
