output to buzzer from MC9S12DP256B
I am using MC9S12DP256B minidragon evaluation board with an SRF04 transducer. I have written my program in C and have successfully downloaded the program on to the chip. Unfortunately I haven't been able to get a response from my buzzer.
I have attached my circuit diagram and am pasting my code here. Somebody please advise. I really need help to make this work. I have also tried using a IRF530N transistor instead of a 2N3906. I couldn't hook up the IRF530N, I am confused on how to connect this transistor with a 10k resistor and my output from the minidragon chip. Please help.
