im trying to improve this one, i may need your suggestions...  ano pa kaya ang dapat kong idagdag dito... ? o babaguhin? bakante pa ang PORTA. BTW, i am trying also to route the board for a single sided PCB... para magamit ng karamihan. |

how about POTS for the PORTA analog inputs?

pwede rin .. for temp sensing... jumper for either POT usage(variable 0-5V) or from temp sensor...  |

dito sis: http://www.electronicslab.ph/forum/index.php/topic,8296.msg156834.html#msg1568343310 lcd ok sana yan sis, kaso nalalakihan ako ng driver para sa 3310. though, magiging cheaper ang gastos... |

pwede naman separate breakout board.. pero aalisin na natin ang 16x2. parang tulad nito...  alisin nalang yung connector tapos palitan ng header para pwede maisolder sa main board. pero parang papangit... heheh I would still go for 16x2 LCD.... |

tita marce. leave port C for CCP, PWM, SPI, UART, and i2c. then on port D naman ganito na lang. para ma-practice nila na pwede mag switch from input to output. see image. then ULN darlington drivers naman sa port B. for relay, steppers, solenoids, dc motors, buzzer...  |

PORTA will be for ADCs PORTB, for GPIOs. LCD maybe but will still leave RB0 for its interrupt detection capability. tamang tama, we need 6 pins for LCD. Although I am also thinking that we need 7. the seventh pin will be utilized for the LCD backlight. But Martin's suggestion is also good for this. PORTC. Since most peripherals are assigned to this port, we must leave itopen. Siguro yung UART nalang ang lagyan. PORTD. PortD is intended for parallel interfacing, but since most of use rarely use this one, we assign this as for GPIO. we use that strategy of Martin. honestly, wala naman akong time gawin to... hehehe . pag may spare time lang siguro. |

Imbis na nakahilera yung push buttons sa ilalim, 3 by 3 na matrix might be better.

Im using the same circuit for my PIC16F877A demoboard and i got the idea from Flowcode |
