Other Parts Discussed in Thread: PGA900, USB2ANY
Hello,
I am using PGA900EMV development board and Code Composer Studio v6. I have built project, connected to target (I am using XDS200), run->load ->load program. Compiler gives me message: PGA900 OnFileLoaded is done. I assume that PGA900.out file and program was loaded to micro(TI example code).
a) Problem I have is I can't change output voltage. For example if I am changing DAC gain value register, I can see what register values are changing too, but Vout value is not changing ( I am measuring Vout on TP1 wrt TP39). Why Vout is not changing? What I am doing wrong?
b) Also I have connected USB2ANY and PGA900 GUI. In microcontroller mode tried to change bridge value - no changes in Vout value. Why Vout is not changing? What I am doing wrong?
c) In digital mode tried to change bridge value (configured ADC, DAC) - no changes in Vout value. Why Vout is not changing? What I am doing wrong?
Best Regards,
Irmantas
