MSP430I2040: suggest code to configure ADC(SD24) of msp430i2040 controller

kinjal dani

Part Number: MSP430I2040

hello Sir,

Please suggest me the code to configure ADC i.e SD24 of msp430i2040 controller, i had tried sample code of ADC i.e msp430i20xx_sd24_01 for three ADC channel, but my problem is that i does not get constant value of voltage, it goes on vary though i had not given any external voltage on that pin. I had made fix voltage on that pin using CT switch. alos i need 4 AI channel voltage by ADC channel using msp430i2040 controller

Hi Kinjal,

Which board did you use?

Did you apply fix voltage on the three pins and try to get the ADC conversion value and testing the actual voltage on the pins using a multimeter?

hello sir

i am not using any board but using controller msp430i2040 mounted in my PCB , in that i am giving fix voltage on 3 pin of ADC and mesaure the voltage count on modbus register. this count does not remain stable it goes on vary.

Regards,

kinjal
