Hello dear followers, this post is special for us, the last post of the year, and this show the first test with a small program in the hardware, the famous "Hello World", for this we use the MSP430F2013, a 2X16 LCD, an external 9V , a 5V regulator (LM7805), a 10K trimpot for LCD contrast and several jumpers for connecting the protoboard.
Since we will use 4-bit mode, the LCD must be connected only in their last 4 pins (D4, D5, D6 e D7) plus (RS, command and enable).
For this configuration we have the following electric diagram:
In our case we have the LCD backlight controlled by the timer (LM555), but that's a topic for another post.
