Then you build a circuit according to the plan shown below. The Arduino UNO must be still selected as board in this step. Select the ArduinoISP sketch from the examples of the Arduino IDE and upload it to the Arduino UNO. Select “ATmega328 on a breadboard” Turn the Arduino into an ISP programmer restart the Arduino IDE and check whether you can find the entry “ATmega328 on a breadboard (8 MHz internal clock)” in the boards menu (but not yet select):.unpack the downloaded zip file in the hardware directory.Space requirements, power consumption and costs ( Preferencesif you don’t know which directory it is. Then it is better to operate only the ATmega328P with a minimum of peripherals. But if you immortalize your project in solder and wire at the end, the Arduino becomes unwieldy. You don’t have to worry about the power supply, an oscillator is already attached to it, you don’t need a programmer and you have the labeled pin headers. A few points in advance Why operate the ATmega328P standalone? The ATmega328P (PU)Īrduino boards are without question very comfortable when it comes to developing projects. Take a look at it and decide for yourself what you might want to try. Programming the ATmega328P within the Arduino UNOĮach of these paths has its advantages and disadvantages.Variant 3: Arduino UNO and FTDI232 / 16 MHz.Variant 2: Arduino UNO and FTDI232 / 8 MHz.There is more than one way to skin a cat and I’ll show you some of them: ![]() LGT8F328P LQFP32 replaces NANO V3.In this article I would like to show how you can operate the heart of the Arduino UNO, the ATmega328P, standalone. KEYES Open Source LGT8F328P Control Module Development Board LINKS LINKS LINKS LINKSĪn excellent source of English datasheets and documentation by Andrew Watterott ![]() To display that number in its intended HEX format do this:ĭavid Buezas has written an entire boards description for all frequencies and it allows us to dispense with setting the clock prescaler. To retrieve the number (it's read-only) do this in your sketch setup(): ![]() Is your Serial Monitor speed set to 9600? Did you select the 32MHz variant of the board? Did you restart your Arduino IDE after replacing the boards.txt file? Did you put the unzipped folder under the correct hardware folder in the Arduino Sketches? What's this GUID then?Įach LGT8F328P has a unique GUID (serial number) built in. Then your board might not be running at 32MHz. If you get this instead (and your Serial Monitor is set to the correct speed) In the Serial Monitor window you should see this: Remember, in your future sketches, always add in the #include for the as shown in the video.įinally, add in this statement before anything else in the setup(). The original LGT8F328P board will now be described as (16MHz) Go to Tools, Board and scroll down until you see the next set of LGT8F boards, one of which will be 32MHz variant you just added. TestingĤ Fire up the Arduino IDE (or restart it if already running) Then copy the boards.txt in this GitHub there in place of the one you just deleted. In the Hardware -> LGT -> AVR folder delete the boards.txt. If you do not have a hardware folder in your Arduino Sketches folder, just create one. There's a copy of this zipped folder right here on my GitHubĪnd move the unzipped LGT/avr folder to under the hardware folder in your Arduino sketch folder. 6 Simple Steps to get a LGT8F328P-based board running at 32MHzġ Download the LogicGreen zipped resources here The 6 simple steps to get a LGT8F328P-based board running at 32MHz are listed on my GitHub. Or you can have a Pro-Micro sized device that will require a USB-to-Serial adapter to program. My device looks like this (and well worth it for experimenting with)īut the final device is Nano sized, and a drop-in pin replacement So we're looking at the 32MHz Nano-sized drop-in replacement but I'm using a different sized development board just for ease of use in the video.
