I was curious what can MSP430F149 do. So I took MCU, LCD (one old PCB with MSP430F149 and 128x64 display), chose right crystall frequency and started this project. When DSO worked I tried to add FFT plot (to understand how it works and to see what can be done with this MCU). Finally I added various sampling modes, trigger setup, cursors. You can see my source code here.
