Now Let’s Set Up Our Development Environment
To begin your Nuvoton 32-bit microcontroller project, you'll need the right tools. Ensure you have the following:
1. Hardware:
The official development board for Nuvoton N76E003 is the NuTiny-N76E003 SDK board with a programmer.
2. Software Development Kit (SDK):
Download the softwares listed below
Board Support Package for Keil - N76E003
Keil Micro Vision - C51 (IDE with Compiler)
3. Integrated Development Environment (IDE):
Download and install Keil Micro Vision and C51 Compiler which is used to compile code for 8051 architecture.
To flash the program to the microcontroller we will use Nu-link Keil driver interface.
Other than the compiler and IDE, install the Board Support Package (BSP) Library for N76E003.
Lets Now Start Coding
Now after successfully getting all your hardware and software requirements and finishing their downloading and installing process we can start building our first project i.e Blinking an LED.
Open Keil uVision and select the proper boards and upload method, and paste the following code in the editor:
#include "N76E003.h"
#include "SFR_Macro.h"
#include "Function_define.h"
#include "Common.h"
#include "Delay.h"
void sw_delay (int ms);
void main(void){
P14_Quasi_Mode;
while(1){
P14 = 0;
sw_delay(250);
P14 = 1;
sw_delay(250);
}
}
// Software based delay. Time is not accurate.
void sw_delay (int ms){
int a, b;
for (a=0; a<1296; a++){
for (b=0; b<ms; b++);
}
}
Now compile this code and it should show output as follow:
Build started: Project: LED-Blink-Test
Build target 'Target 1'
assembling STARTUP.A51...
linking...
Program Size: data="9.0" xdata="0" code="118
creating hex file from ".\Objects\LED-Blink-Test"...
".\Objects\LED-Blink-Test" - 0 Error(s), 0 Warning(s).
Build Time Elapsed: 00:00:01
Now Let's Upload Code on N76E003 using Nu-Link
Connect the development board with berg pins. Check the connection properly and match it with the programmer and the development board pin names.
Connect the hardware into the USB pin of the PC. Make sure that the power led to the development board is glowing perfectly as shown below.
As shown in the above image, the PWR LED is glowing in Green color. Go to the Keil compilation toolbar. Press the Build target button and the load button.
The program will be loaded in the chip and the LED will start to blink as shown in the image below.
