Speeding up the chip

Post by Jodoku » Sat Jul 31, 2010 8:07 pm

I have a question:

I am working on a program in Simulink that models a 30f4011 chip as a sort of wireless node transmitter/receiver. The basic premise is that after every fixed period of time, it sends a data packet and then looks for an acknowledgement. If it does not receive one, it will resend (up to 9 times). I have accomplished this by creating an embedded matlab function, and I use a limited counter to keep track of time. Ideally I want the aforementioned period of time to be 1 microsecond or even 1 nanosecond, however I can not get it to run nearly this fast. I am reading the send data in matlab via a serial connection from a dsPICDEM2 board. How can I go about fixing this? I have attached the model for reference.

Thank you
