Hello,
I am having a hard time to get the BOOSTXL-ADS7841-Q1 to work with the TM4C1294 LaunchPad. The behavior is as follow.
If I use the GUI program, I am able to get the data and everything as expected. However, if I program my own application to interface with the IC through SPI, no matter what I do, it doesn't seem to work.
Please advises me on the situation, should I buy a standalone IC and work with it rather than using the BOOSTXL-ADS7841-Q1?
Thanks,
Alex
Tom,
You make my gloomy and snowy weekend a lot better!
I checked the /SHDN pin and it was held low... The datasheet stated that it was always pulled high by VDD (See picture below), that is why I didn't question the integrity of the pin.
I check the resistor R21 that was connected to the pin and the side it is connected to VDD has 5V while the side it is connected to /SHDN is 0V.
What would be the cause of this? Since it is still working with the GUI program...
Thanks,
Alex
