18 Feb 2009 6:36 UART problem....

Hi, I am now using PIC16F88 which has hardware UART for my project. Previously the asm code is written such that to display the reading to a 16x2 LCD. But now i need to have these data input to another RF module. The RF module has 2 pins for UART data IN and OUT. Beside, it also has 4 pins for analog input/digital IO. I knew UART routine is needed to use the UART input but I might want to ask how if i connect it to the digital IO? Is UART needed for it? Whats the difference between UART and the digital IO?

ASM code here:

The module pins:

This looks like quite a verstile module.
You would still connect to it using the uart pins, looks like you can configure it using the uart.
It also offers a pwm output, Analog to digital channels and general purpose digital I/O lines.
There is only one answer to your question. You have to get the data sheet for the module and study it to see what it can do.
