what kind of modbus:
- RTU modbus or ASCII modbus ?
- SLAVE mode ?
- dialogue trough serial link ?
point to point (RS232) or multi slave (RS485)
I did some trial any years ago on modbus exchange with industrial devices.
i add some tools written in VB6 to test modbus

Hi, I am struggling with getting the threshold voltage (reference voltage) for the sensors to suite the pic16f887 to recognize as logic zero and logic 1. I am using SENSOR HOA0709-1 with comparator to microcontroller.
I have threshold voltage of 1.6v for white surface and 3.6v for black surface; this does not do any effect as I programmed it to be

I am using pic16f887, QL200 development board and MikroC. My project is very simple and consists only in using digital inputs/outputs.
I should define the following SFR:
