INA260EVM: Problem regarding uae of INA260EVM board as simple INA260 cheap for current sensing circuit.

Part Number: INA260EVM
Other Parts Discussed in Thread: TMS320F28027, , INA260, CONTROLSUITE

Hello,

My application needs to read currents but instead of INA260 cheap I have a INA260EVM board. I cannot use it from GUI as I am want to fis the sensor on my circuit board. I am kinda puzzled about how to use the given INA260EVM board with direct I2C communication protocol with my microcontroller TMS320f28027. I gonna need this current value to control the a PMDC motor which is my final target.

    Hello Kiran,

    I would start by looking for all available I2C libraries for the development environment you have chosen. Then you will want to I2C commands specific to the INA260. Maybe first determine if you can establish an ACK from INA260 after sending a command to INA260's slave address. Then you will have to program the confiugration register.

    You can try basing some code off one of our LInux driver codes for other digital current sense amplifiers here: www.ti.com/.../ina2xxsw-linux

    Thank you for you reply.

    I figured that out about how to use ina260EVM board as ina260 sensor but the problem which is I am facing is I do not know how to intialize and read or write to this sensor via i2c communication with tms320f28027 microcontroller.  I need a clear direction about how to use ina260 with this piccolo microcontroller. I have tried using the given example of i2c communication of eeprom in controlSuite but it isn't working for me since, I want to read three registors viz. current, voltage and power and write one configuration register of ina260.

    My main objective of this use this current readings to implement a PI controller for PMDC motor where set point for it is being given by user by a potentiometer from which I am reading the analog values succesfully.

    Thank you for your response.

    Hello Kiran,

    I do not have much experience with this MCU or I2C example code. I think you will best be served by posting to the C200 32-bit Microcontrollers Forum here:
    e2e.ti.com/.../171

    You could also reach this forum by using the TMS320F28027 as the part you having trouble with. Thanks for choosing TI.

    Best,
