 You should be aware that other target device use OSCCON instead of OSCFRQ, but the IntOsc Helper allows for that.

 The device datasheet should detail the type of oscillator available to the device.
-Here we have the datasheet for the PIC16F88 device listing the options available for the internal oscillator.
+To control the internal oscillator speed, a c code block will require adding at the very top of main, so its the first icon to be accessed.

+Luckily, we don't need to dive into the datasheet to work out the code to set the internal oscillator to the correct speed.
-Using a C code icon at the very top of the Main macro we can specify which speed the microcontroller should start-up with.
+This can be found on left of the '''Components Libraries''' and enter '''intos''' in the search bar.
-To access a register using PIC use the register name in all lower case. e.g. "osccon"
+'''Setting the hardware at the correct speed for PIC16F18877'''
-For the PIC 16 bit devices (dsPIC and PIC24) and AVR use the register name in all upper case. e.g. "OSCCON"

-Remember to end the line of C code with a semicolon to mark the end of the instruction.

 A [[One second LED flasher]] test can be very useful to confirm if your device is actually running at the intended speed.
