ATMEGA328P-PU Microchip Core piece Arduino minimum system

Date: 07-01-2021 ClickCount: 147

Material preparation:

1. ATMEGA328P-PU

2.22pF Ceramics

3. One crystal oscillator (8M for "ATmega 8A-PU", "ATmega 8PU-8PU", 16M for "ATmega 8-16PU")

4. One USBtiny ISP

 ATMEGA328P-PU

The minimum systematic hardware part, however, Arduino screaming, Arduino parallel hardware, certain required hardware, Arduino 1.0.1 IDE for current use Used USBTINYISP, ICSP port 1 port D12, 3 port D13,5 contact RESET, 2 port contact VCC, 3 port contact D11, 6 port GND. Preliminary USB line connection,  USBTINYISP After that, I entered Arduino 1.0.1 IDE, "Hardware" selection Arduino NG, "Editing device" selection USBTINYSIP, Point 击 "Shosho Bootloader", Can be seen as a loader-like BUSY light start Ryo, overcoming 1 After the division, the bootloader was released, and the bootloader was released, and then the BLINK software, the D13 pulling leg 1 second import high electronic flat, the 1 second import low electronic flat, the Ryoka D13 pulling leg contacting one LED, and the meeting was available. Effectiveness. After the selection of "Compiled language", the LED of the D13 D13, the LED of the lead, and the LED of the lead, which can be used, have been completed.

Exclusion used editorial device loading, Iya can oppose loading good Bootloader-like minimum system serialization Kushiguchi loading, but the cause ATMEGA328P-PU Chip surface packaging plate electric circuit electrical environment comparison difference, guidance and lawless use high-speed communication Bootloader, reasonably necessary progress Actually.

Demand conversion 0022 version of this IDE. Neck tip illuminating Top-level walking program ATMEGA 8-core single-sided printing 0022 IDE-like NG restraint board-like Bootloader (This Bootloader speed is a little, but it is easy to implement. Next arrival indicator light. RST pull leg skewer  1 piece 10K electric block connection VCC, RST pull leg simultaneous contact 1 piece arranging, arranging total one end connection GND for the next work.

After that, USB TO TTL-like VCC contact minimum system, VCC-contact GND, GND-contact GND, TX-contact D0, RX-contact D1. Arduino 0022 IDE Control board selection NG ATMEGA8, Selectable end number, Same sample selection BLINK example child, compile compilation, download. After loading the point, it is the most relevant walking program, and after loading the main point, it is required to be hand-crafted, and the bottom wrapping plate is repositioned, and this sample program ATMEGA328P-PU Board can be installed normally. After the download, the LED has been completed.
