ak96 4 Posted August 23, 2018 Share Posted August 23, 2018 I made a heart rate sensor, and prototyped it with the launchpad. The mcu reads BPM and displays it on an LCD. I now want to create a pcb without the launchpad. I've attached what I have so far. I'm powering everything from a 9V battery, so I have a 3.3V regulator which I will use to power the MSP430G2553. Can I just connect the the output of the regulator to the VCC pin, and connect all the other pins to the circuit as I did with the launchpad, or are there other considerations I need to account for? Also, how do I debug and edit the program while the microcontroller is on my custom pcb? Quote Link to post Share on other sites
