UCD9081: Programming in production

Ben Strawbridge1

Part Number: UCD9081


Hello,

I am trying to organise production programming of this sequencer, and can export a .hex file, but can't work out which tool I should be using to program the sequencer. 

My only real goal here is to great a file which can not be easily edited/changed so that it can be used in a production environment without having to check that it has not been altered by production staff.

Please can you help?

    Hello

    UCD9081 has a standard I2C interface. So any I2C tool can work with it, for example, a I2C from micro-controller, micro-processor, FPGA, or USB-based I2C tool.

    The production shall use the hex file format generated from GUI, there is checksum embedded.

    Of course, they have to follow the command protocol defined by the UCD9081 which is defined by https://www.ti.com/lit/pdf/slva275

    Regards

    Hello,

    yes I can see the .hex output and I have seen this document, what I can't find is any TI tool that will program this onto the device

    I have got a TI USB-TO-GPIO programmer, I just need to know what tool can use the .hex file and program the device.

    Kind regards,

    Hello

    The UCD9081 GUI TOOL can only export the hex file but it does not support importing function.

    You have to use own tool to import the hex file, mainly requires SW work to parse the hex file and pack it with right command protocol.
