LGT8F328P-LQFP32 MiniEVB Arduino Nano V3.0 HT42B53 b27

Mini Arduino Nano V3.0 LGT8F328P-LQFP32 MiniEVB  is an Alternative Arduino Nano V3.0 ATMeag328P with serial HT42B534-1 SOP16 USB Driver. It is an improved ATMega328P with this cheap clone Logic Green LGT8F328P

            

Features of Mini Arduino Nano V3.0 :

1. 8F328P-U MCU used by the LGT8F328P, is a Atmel MEGA328P compatible chip.
2. 8F328D architecture design is relatively new, peripheral functions far stronger than Atmel MEGA328. Especially the program encryption ability is far more than MEGA328.
3. 8F328D can use 3V3 and 5V power supply running at 16M frequency, excellent level compatibility.
4. Built-in high-precision RC, no external crystal can be stable operation.
5. Less And decreases in peripheral instrument parts, Circuit Design Is Simple.
6. 12-bit ADC (analog-to-digital conversion)
7. On Board DAC
8. Owned Inventory the GUID (Unique own ID) Can Be For on used chip solutions Encryption Program.
9. A Built-In .internal 1.024V / 2.048V / 4.096V ± 1% Calibratable Source Reference voltage software.
10. The PWM pin adapter Number: the D3, the D5, the D6, the D9, the D10, D11.
11. MCU LGT8F328P
12. FLASH 32Kbytes
13. SRAM 2Kbytes
14. E2PROM 0K / 1K / 2K / 4K / 8K (FLASH Share)
15. PWM 8
16. Frequency 16MHz (Maximum 32MHz)
17. ADC 6 passageway12 position
18. DAC 1passageway8 position
19. UART 1
20. SPI YES
21. TWI (I2C) YES
22. GUID YES
23. Internal benchmark 1.024V / 2.048V / 4.096V ± 0.5%
24. System logic level Factory 3V3 (switch from pad to 5V)

Now we’re going to look at the 32MHz Nano-sized drop-in replacement

 

6 Simple Steps to get a LGT8F328P-based board running at 32MHz

1 Download the LogicGreen zipped resources here
https://github.com/LGTMCU/Larduino_HSP
There’s a copy of this zipped folder right here on my GitHub

2 Extract the download (unzip it)
and move the unzipped LGT/avr folder to under the hardware folder in your Arduino sketch folder. If you do not have a hardware folder in your Arduino Sketches folder, just create one.

Your structure should look like this:

3 Replace the boards.txt

In the Hardware -> LGT -> AVR folder delete the boards.txt.
Then copy the boards.txt in this GitHub there in place of the one you just deleted.

Testing

4 Fire up the Arduino IDE (or restart it if already running)

5 Select the right board
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. The original LGT8F328P board will now be described as (16MHz)

Remember, in your future sketches, always add in the #include for the <avr/power.h> as shown in the video.

Finally, add in this statement before anything else in the setup().

6 Load the Prime Numer Test sketch from this GitHub, build and run.

In the Serial Monitor window you should see this:

If you get this instead (and your Serial Monitor is set to the correct speed)

then your board might not be running at 32MHz. 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?

Each LGT8F328P has a unique GUID (serial number) built in. Useful for encrypting things.
To retrieve the number (it’s read-only) do this in your sketch setup():
uint32_t guid = (uint32_t)&GUID0;

To display that number in its intended HEX format do this:
Serial.println(guid, HEX);

Simples, right?
