Tool/software: Code Composer Studio
Hello,
We're working on a project using the CapTIvate MCU development kit and are having trouble getting data/communication from the board. The board seems to be communicating with the design center, but when we try using a USB connected to a basic serial monitor instead we get no output at all (including noise).
Is there anything we should change from the automatically generated code to get UART communication with USB or through TX/RX pins?
So far we haven't made any modifications to the base code. We are still getting communication to CapTIvate design center which implies the board is capable of outputting data.
Our second question is in regards to scaling up grid sizes on mutual capacitive channel grids and how this affects CapTIvate design center.
When we use a 4x4 channel we are able to see touch sense data in CapTIvate without any problems. However, as we scale up the number channels and physical size of the board we notice that CapTIvate design center becomes unstable (and causes CPU usage to skyrocket to somewhere close to 100%).
Is there something we're overlooking that could cause this to happen?
We'd ideally like to be able to tune an 8x8 board of sensors (i.e. all 16 channels) via the design studio, but since this is happening we are limited to using serial communication to/from the board.
Thanks very much for your time!
