Part Number: TDC1000-TDC7200EVM
Tool/software: Code Composer Studio
Hello,
I've been using the TDC1000-TDC7200EVM to measure water flow using transducers sensors, but I want to use it to measure flow without the USB/GUI, using a battery as a power supply and collecting the data by the GPIO3 UART TX using an Arduino. I was thinking to cut the USB cable and conect a battery directly on it. What voltage should I use in this case?
I made some modifications in the original firmware to have this working:
First, I changed the 'TDC1000_UART_Stream' = 1, to have the UART STREAM enable as default:
Then, I changed the 'tof_graph_state' = 1, since the data is only sent when the graph is started.
And it works for a while. When I connect the USB, it starts to send the data to Arduino immediately, without even opening the GUI. But, after approximately one minute, it stops to send the data, and also, the LED in the board stops blinking. When I press "start graph" at the GUI, the data are being sent again, and when I press "stop graph", it stops again after a while. It seems to enter in a sleep mode, am I right?
I can't find out how to solve that, any idea?
Thanks in advance!
