pga309evm-usb usage

Hello all,

I'm using the pga309evm-usb after I had problems with the pga309evm without usb. This evm looks far more professional the the predecessor but i'm facing some problems.

I have connected a full bridge sensor end setup all the jumpers to ext mode for the external bridge. If I want to change the gain in the block diagram the green light ("Pending changes need to be written") lights up and after "Write all reg" the change is active. But if  I want to change the zera dac, gain dac or mux then the green light does not light up. I also see no activity on the PRG1 pin if I do "Write all regs". What might be wrong?

 

Thanks in advance,

Cor

    Hi,

    I got new software from TI (Arthur Kay). Every thing works fine now. It is exactly working as expected. It's a very good tool.

    All problems are solved now.

    Thanks,

    Cor
