Other Parts Discussed in Thread: MSP430G2553, ADS1247, ADS1220, ADS1248

i am trying to program my MSP430G2553 with AD7793/AD7794 via SPI to measure 4 - 20mA analog signal

Can someone post me some example codes a for the IAR compiler and schematic to communicate them?

    Hi Thuy,

    as written in the other thread already, our forum is used to help customers with questions regarding devices from Texas Instruments. If you have questions regarding devices from Analog Devices please contact them through a different channel. I am hoping for your understanding.

    ADS1220, ADS1247 and ADS1248 would be solutions very similar to the devices you mentioned and we will be happy to support you with questions regarding those devices. We could e.g. share sample code for using ADS1220 with an MSP430 (not necessarily the exact version you asked for though).
    ADS1220 is ideally suited to implement 4-20mA measurements.

    If you need help with the MSP430 please feel free to post your questions in the respective MCU e2e-forum.

    Regards,

    Hi Thuy,

    The MSP430 is supported in the microcontroller forums.  Generic 'c' code and assembly functions for IAR can be found for the MSP430G2553 at the following link:

    There are also example projects for the the LaunchPad that can also be found with links on this page:
