I'm trying to get more familiar with reading and writing to the memory of a 12F683 @4Mhz using PBP3 and simulating it on Proteus's serial out display.
What I want to know is how to write a large number, word sized, to memory, byte size, and then reassmble it. Like this
Memory 4 value is 10,000. What I'm trying to do is write memory 4 byte 0 value to memory location 3 and byte1 value to memory location 4. Then I want to read those bytes and assemble them into a word and display it.
I cut and pasted this code from the full program so it may be awkward in places. Your insights would be greatly appreciated.
