Product Number: AD5940
Hi Folkes,
After running AD5940_HWReset();
AD5940_Initialize(); functions and verifying the ADIID and chip-id of AD5940, I am trying to to set GPIO_Pin_0, GPIO_Pin_1 and GPIO_Pin_2 to output pin and set the value as high for AD5941.
I tried following code:
:
uint32_t j = AD5940_ReadReg(REG_AGPIO_GP0OUT);
uint32_t i = AD5940_ReadReg(REG_AGPIO_GP0IEN);
uint32_t k = AD5940_ReadReg(REG_AGPIO_GP0OEN);
AGPIOCfg_Type agpioCfg;
/* Configure AGPIO Pin 0, Pin 1, and Pin 2 as output pins */
agpioCfg.FuncSet = GP0_GPIO | GP1_GPIO | GP3_GPIO ;
agpioCfg.OutputEnSet = AGPIO_Pin0|AGPIO_Pin1|AGPIO_Pin2;
agpioCfg.InputEnSet = 0;
agpioCfg.PullEnSet = AGPIO_Pin0|AGPIO_Pin1|AGPIO_Pin2;
agpioCfg.OutVal = AGPIO_Pin0|AGPIO_Pin1|AGPIO_Pin2;
AD5940_AGPIOCfg(&agpioCfg);
//AD5940_AGPIOSet(AGPIO_Pin0 | AGPIO_Pin1 | AGPIO_Pin2);
j = AD5940_ReadReg(REG_AGPIO_GP0OUT);
i = AD5940_ReadReg(REG_AGPIO_GP0SET);
k = AD5940_ReadReg(REG_AGPIO_GP0OEN);
}
But not able to get the proper GPIO output level after running this code?
Do I missing something? Do we require pull-up resistor to do this action?
If there is change in code required then let me know? Or I am missing some configurations? I am using STM32WB55xx mcu for the SPI communication.
