nucleo L476RG and AD9834

hello,

I try to use the AD9834 with the nucleo L476RG and I have some issue.

I use Spi 1 , send that I think good, but it's not work.

here are my code, I hope someone can help.

thanks and sorry for my english

int PINSW = 1;
 
//int led = GPIO_PIN_5;
int AD_reset = GPIO_PIN_15;
int AD_SDA = GPIO_PIN_14;
int AD_SLK = GPIO_PIN_13;
int AD_FSY = GPIO_PIN_12;
int AD_CSK = GPIO_PIN_5;
 
uint8_t spitx[2];
 
void AD9834_Reset(int value){
    if(PINSW){
        if(value)   HAL_GPIO_WritePin(GPIOB, AD_reset,1);
        else        HAL_GPIO_WritePin(GPIOB, AD_reset,0);
    }else{
        if(value)   AD9834_CONTROL |= 0x0100;
        else        AD9834_CONTROL &= ~0x0100;
        //AD9834_SendWord(AD9834_CONTROL);
    }
}

Hello @Seth1er​  and welcome to the STM32 Community 😊 ,

Please share your ioc file and more details to help you solve your issue :

Which version of CubeL4 and CubeMx are you using ?

In the debug, where the code hangs/stop ? Do you get an error message ?

hello,

here are the ioc file.

cubeide version :

Version: 1.5.1

Build: 9029_20201210_1234 (UTC)

I don't know what is CubeL4 sorry. if it's the nucle version, i don't know how to check.

In fact I don't have any arror message. the code is load, I send some data on the SPI to the AD9834 but I don't have any signal.

after some try I have one success, with code below( with luck) I have a 6,25MHz signal. I don't understand why, because it doesn't correspond to the 9834 formula.

If I try an other value, I don't have any signal.

I don't know if it's an SPI issue, a sequence issue .

I don't found any exemple on net between SMT32 and AD9834. a lot with arduino, but all exemple don't use the SPI, they make they own one.

I hope someone can help me. it seem to be easy but i can't .

The AD9834 is on a "eval" board with the clk inside a 75MHz.

BR,

just a up,

if someone can help me on this please. or give me a simple code to set a freq with STM32 and AD9834, I will understand
