PIC or AVR ATMEGA ATMega8535 PIC16F87X
Microcontroller more and more, to choose to use the PIC 16F microcontroller or AVR family ATMEGA 8535 just need googling that here. System works sama2 work on both the base 8-bit PIC or AVR ATMEGA. PIC or AVR basically the same microcontroller that has an analog input facilities in accordance with what I need. Feature owned by PIC and AVR ATMEGA too much alike. From the PIC feature on the analog input also has AVR ATMEGA. Feature ADC also owned by PIC or AVR ATMEGA even between PIC and AVR ATMEGA is sama2 have ADC with many channels all (plus mantab all). From the feature control PWM PIC and AVR ATMEGA also have. Well bener2 added mantab world with the presence of PIC microcontroller or AVR ATMEGA this, first MCS51 family still AT89C5x or AT89S5x wrote that in use. After dipikir2 should also be detailed feature between PIC and AVR ATMEGA with details.
