ADF4153 using Arduino Due

hello,

before im new here @ arduino. worked pic , other mcu-s, not totally without knowledge.

but have never used spi, , have problem now. have make pll using adf4153, , given data analyzer works. pll wont move @ all. hoping else tried pll , can provide help.

here code

code: [select]

#include<spi.h>
#include<liquidcrystal.h>

liquidcrystal lcd(12, 11, 5, 4, 3, 2);
spisettings settingsa(2000000, msbfirst, spi_mode1);
const int slaveapin = 6;
unsigned long rtristart=0x000003;
unsigned long rtri=0x3c7;
unsigned long rdva=0x13c2;
unsigned long rjedan=0x144191;
unsigned long rnula;
unsigned long integer;

void setup() {
  spi.begin();
  lcd.begin(16,2);
  lcd.print("pisem init");
   pinmode (slaveapin, output);
   delay(100);
   
  spi.begintransaction(settingsa);
   digitalwrite(slaveapin, low);
   spi.transfer(rtristart>>16);
   spi.transfer(rtristart>>8);
   spi.transfer(rtristart);
   delay(100);
    digitalwrite(slaveapin, high);
    spi.endtransaction();

 spi.begintransaction(settingsa);
   digitalwrite(slaveapin, low);
   spi.transfer(rtri>>16);
   spi.transfer(rtri>>8);
   spi.transfer(rtri);
   delay(100);
    digitalwrite(slaveapin, high);
    spi.endtransaction();

     spi.begintransaction(settingsa);
   digitalwrite(slaveapin, low);
   spi.transfer(rdva>>16);
   spi.transfer(rdva>>8);
   spi.transfer(rdva);
   delay(100);
    digitalwrite(slaveapin, high);
    spi.endtransaction();

     spi.begintransaction(settingsa);
   digitalwrite(slaveapin, low);
   spi.transfer(rjedan>>16);
   spi.transfer(rjedan>>8);
   spi.transfer(rjedan);
   delay(100);
    digitalwrite(slaveapin, high);
    spi.endtransaction();

    delay(1500);

    //integer=2500/20;
    lcd.clear();
    lcd.print("frek 2500m");

    rnula=0x1f4000;//integer*16384;

     spi.begintransaction(settingsa);
   digitalwrite(slaveapin, low);
   spi.transfer(rnula>>16);
   spi.transfer(rnula>>8);
   spi.transfer(rnula);
   delay(100);
    digitalwrite(slaveapin, high);
    spi.endtransaction();
   

}

void loop() {

 
 
}


i not using loop, trying set fixed frequency.

hi,

welcome forum.

can post link specs/data pll ic please.

thanks..   tom...
