DAC81416EVM: DAC81416EVM Programming Method

Hi,

I can help you how to program DAC81416 EVM

1. USB2ANY programmer must need to program EVM which is not part of DAC81416EVM kit and you have to order separately.

2. Once you got the programmer , please refer DAC81416EVM user guide for hardware setup, software installation and programming.

Hope this will help you.    

Thank you for reply. 

However, I already did what you reply. The user guide and data sheet that TI provides don't include how to program it. 

What I want to know is how to program the output of the DAC automatically as I programmed at the interface I added.

I have the USB2ANY and can connect it.

Hi Seungeon Lee,

I can see from GUI screen that USB2ANY not detected in PC, whether you connected USB2ANY in you PC ? It seems not connected

(it look like in Demo mode)

After USB2ANY connected with PC and opening GUI you can see screen as below when USB2ANY interface establish connection.

You can perform DAC programming  once connection are established.

Hi Anbu,

I did all what you write before. However, I still have the same problem. The datasheets and userguide TI provides don't explain how to write code to control the DAC. i hope you show me some example programming that changes the output according to time.

Hi Senugeon Lee,

I can help you on refence programming sequence. before that i want to ensure your h/w setup working fine.

Can you able to establish USB2ANY hardware connection with EVM ? did you able to seed hardware connected status on GUI ?

I'm in the state. Is it right?

Could you please confirm supply voltage at J7 connector at EVM 

J7.3 ---- GND

J7.4-----VIO----?

J7.5-----VDD/VAA-----?

J7.6 -----VSS >  ?

J7.7-------VCC> ?

Without power device will not program . so power up device 1st 

 After power device with all recommended supply 

1. Select DAC Range base on VCC and VSS supply ( Ex. VCC=5 V and VSS =0V)

     - DAC Range should be select 0-5V for specific channel 

2. Enable DAC channel 

3. Device should be power on mode ( by default in power down mode)

4. Provide DAC code and DACOUT box for specific channel.

5. Measure o/p an J1 connector for specific channel

find the screen shot for DAC channel0 selection for 0-5 V range and 0 volt output

1. 0 V output 

2. mid code =0x8000, 2.5 V output 

3. full scale 0xFFFF, 5 V output

Hope this will help to solve your issue.

Change short 1-2 of J10 

EVM software can't be automated and if you want to control DAC you need SPI host ( example : Microcontroller or FPGA) 

Are you using any Microcontroller as host ? 

Um... you mean change the 1-2 of J10 to 2-3 of J10?

Oh!! I never know that I need Microcontroller. I will find more about it. 

I really really THANK YOU SOSOSOSO MUCH
