ENC28J60 reg set HELP
PostPosted: Sun Jan 17, 2010 8:08 am     Reply with quote
I'm trying to setup 'led config reg' to make one led blink fast and the other one blink slow.

My code look like this:
Code:

#define CS  PIN_D2

void main()
{
 
output_high(CS);
delay_ms(100);
 setup_adc_ports(AN0 |VREF_VREF);
 setup_adc(ADC_CLOCK_DIV_8);
set_adc_channel(0);
   setup_psp(PSP_DISABLED);
   setup_spi(SPI_MASTER|SPI_L_TO_H|SPI_CLK_DIV_4);
   setup_wdt(WDT_OFF);
   setup_timer_0(RTCC_INTERNAL);
   setup_timer_1(T1_DISABLED);
   setup_timer_2(T2_DISABLED,0,1);
   setup_timer_3(T3_DISABLED|T3_DIV_BY_1);
   setup_comparator(NC_NC_NC_NC);
setup_spi(SPI_MASTER | SPI_H_TO_L | SPI_CLK_DIV_16);
 

output_low(CS);
spi_write(0x5F06); //  SELECT '2' REG BANK
//output_high(CS);
//delay_ms(10);
//output_low(CS);
spi_write(0x5410); // WRITE 'x10' to 14 REG of 2 BANK to point to the 'led config reg'
//output_high(CS);
//delay_ms(10);
//output_low(CS);
spi_write(0x563B); // WRITE UPPER BIT VALUE
//output_high(CS);
//delay_ms(10);
//output_low(CS);
spi_write(0x57A0); // WRITE LOWER BIT VALUE
output_high(CS);

//spi_write(0x214DD0); //write 0x80 to SPI device
}

Code has no effect ;/
Leds are off all the time.

What am I doing wrong?

What size value does spi_write take.

I have no idea.

As is in the Datasheet of ENC.

Im writing for example spi_write(0x5F06);
to point to the 2'nd bank by writing to the ECON1 register.

spi_write(0x5F06); is equal of
bin (010 11111 00000110)
010 mean that we will Write Control Register
11111 is pointer to the register (in this case ECON1)
00000110 is new value to be written into register.
So im sending 2 bytes.

-------
Is there anyone who work with ENC and is able to give me clear answer ? [;

Download the CCS manual and look at the allowable size of the
parameter for the spi_write() function. Hint: it's not 16-bit.
