18F67J50 with HMC6352
PostPosted: Wed Apr 11, 2012 1:23 pm     Reply with quote
Hi,

I hope anyone here can help me.
I try to get the HMC6352 working with my PIC.

Routine:
start
send slave write adress (0x42)
send slave adress to read (0x00)
delay
start
send slave read adress (0x43)
read register
stop

The only answer i will get ist 0xFF.
I also checked the communication with an oscilloscope, the voltage level is within the borders. 10k PullUps installed (the rising edge is a little bit sloped, lower pull-ups would resolve this, but still the same response)

Here's the code:
Code:
#include <18F67J50.h>
#fuses INTRC
#use delay(crystal=8000000)
#use rs232(baud=57600,uart2, parity=n, bits=8, stream=rs2)
#use rs232(baud=9600, uart1, parity=n, bits=8, stream=rs1)
#use i2c(Master, scl=pin_c3, sda=pin_c4, FORCE_HW)

int data1, data2;
//int16 data3;

void read_hmc()
{
   i2c_start();
   i2c_write(0x42);
   i2c_write(0x00);
   
   delay_ms(10);

   i2c_write(0x43);
   data1 = i2c_read();

   i2c_stop();

}

void main()
{
   setup_oscillator(OSC_8MHZ);   
   while(1)
   {   
      read_hmc();   
      fprintf(rs2, "Test %u", data1);
      delay_ms(200);
   }
}



Thanks
Best regards

Please use the forum's search page to look for code in the forum archives.
Search for this: HMC6352
Look in the Code Library forum.

What I am saying is, don't write your own driver. Use the search page
to find a driver in previous posts. Always do this first.
