Hi,
I'm trying to power a Kent Scientific Syringe Pump using the TM4C microcontroller and the kentec lcd, however, when i clicked the start button from the lcd, the syringe pump did not react to the start button being pressed. Is there anything wrong with my UART config?
PS: I am able to build and debug the codes.
Thanks,
Eisen
