Hi,
I am trying to build a microcontroller circuit where I want to read a keypad and transmit the data using serial transmission. Also I want to read this data from another board and display the data there. In this process, I have built my first program that is supposed to read keypad and send data serially. I have designed a program in flowcode, can anyone look at it and tell me what's wrong with the program? It is simply not working.

I am attaching the file here.

Hello,

I've made some changes and it's working now.

Thank you!!
