Tool/software: Code Composer Studio
Hello fellows,
I made a code to interact the MSP430, with the LCD, but now I would like to have it interact with the MSP432.
And I'm having some problems because I want to use specific pins, can anyone help me change the code?
My difficulty is: the MSP430 I use PORT P1 and P2, the problem is in the MSP432 I need PORT P2, P5 and P6
This is my connections LCD->MSP432:
EN -> (P2 + BIT3)
RS -> (P6 + BIT7)
D4 -> (P2 + BIT6)
D5 -> (P2 + BIT4)
D6 -> (P5 + BIT6)
D7 ->(P6 + BIT6)
