micro chip is also viewing, Mr. Giann is looking it. They say XC8 is full free in the google. but no compiling is happening. I am attaching some screen shots . Pl. see any thing I am missing to do while using the MPLAB. Also I have not yet connected PICKIT3/4 to o/p device, will this create any problem for generating hex file?

This is the program I am trying to build on 16f887. But can not build the code. I am very small business man I can not afford to buy dongle or work station now. Pl. see i want to use now for two controller constn. if pic is not free software. I have to try for Arduino or any other free software. how about Arm? Is arduino good for professional work? many people say it is for school projects or hobby work like that. Also I am doing some periferal ckt. since i don’t need to have infinite loop working 24/7, when there is a call it should turn on the MCU and start the loop, after about 10mts. if no call is registered for elevator then MCU shoud stop the loop and stay on standby, is it possible to use sleep mode for this work or can i stop vcc to the MCU if no call is registered with in 10 mts.? Pl. see and solve this issue also.
Waiting to hear from you.
