Hi,

Can MSP430F5438 work good with ADS1258 and ADS1278?

If so are there any devices drivers or codes for the same?

 

Regards,

Dhaval.

    Hi Dhaval,

    The ADS1258 and ADS1278 would both be compatible with the USC of the MSP430F5438 (3-wire, SPI master mode). Unfortunately, we don't have example code readily available for this processor to either the ADS1258 or the ADS1278.

    Getting the MSP430 set up though is relatively straight forward. There are ‘c’ examples (Titled: MSP430F54xx Code Examples (Rev. O)) available from the MSP430 group that initializes the SPI port. The ADS1278 does not require AND commands, so each transfer from the ADS to the MSP430 would consist of writing 0x00 to the transmit buffer three times (for 24-bit data retrieval). The ADS1258 does have command inputs, so the transfer there would consist of writing a command byte of your choosing, followed by 0x00 as needed to retrieve the data. You also need to use a GPIO as the chips select for this device.

    Regards,
