Yet another power supply for microcontroller projects...
here is another 3.3-5v power supply, this time with XC8 Compiler and once again with the small PIC16F887.
at every turn on, will power 3.3v after displaying the welcome message.
it has the Up and Down button, Stand By button and the 3.3 to 5vcd.
Sin embargo, otra fuente de alimentación para los proyectos de microcontroladores ...
aquí es otra fuente de alimentación 3.3-5v, esta vez con XC8 compilador y una vez más con el pequeño PIC16F887.
a cada paso adelante, la fuerza de voluntad 3.3v después de mostrar el mensaje de bienvenida.
que tiene el botón Arriba y Abajo, Stand By botón y el 3,3 a 5vcd.at 0:00 is the board and testing
0:27 the Bootloading
0:45 welcome message
0:55 decrease steps (100mV)
1:07 encrease steps (100mV)
1:17 Stand By Button - I actually use (and abuse) of this feature, which allow me to turn on and off the powered circuit, very important for me, so I don't unplug it every modification/add to it. ~0.3 vcd, and it is just the NPN junction, almost 0 vcd, press again the button (and only that button) will give you the last voltage measure.
1:25 3.3 - 5vcd button, it is just a short cut when u need to supply this voltage and don't want press many times the Up Button, actually goes back to 3.3 when pressed again (1:30).
1:40 stability when put some load, at 3.3 and 5vcd
1:57 Short Circuit and Overload protection, put the circuit at 0vcd until press the Up Button (only at 2:06).
