To asm experts:
To be honest i am a real beginner in asm programming. I hope i can learn from you guys along my period of my project implementation.
OK, I am doing a project on meter reading. A PIC takes current and voltage and make calculations to get the power, watt. Then this data will be displayed to a 16x2 LCD. So until now this step is done. The problem now is, this data I will need to get it over a RF module. This RF module will take this value, transmit wirelessly to the receiver, and ends up at Hyper Terminal on the PC via USB connection.
Here, I have several questions regarding the asm code:
A. By refering to the attachment, I need to know which of the port is the one sending data to the LCD. (As I know there are also controlling bytes to the LCD.) Because if I get lets say RA4 as the one transmitting data, i can use this pin sending data using UART routine to the input of my RF module. If there are 2 pins from the PIC that is sending data, then i might need advice from asm experts how to get it transmitting over the input of my RF module.
I really needs urgent help here and I really really appreciate for your help.
Thanks again.
