These DIP micro-controllers can easily prototype on a breadboard. However we can create a simple prototype board for these chip from scratch. I designed a prototype board for these chips with a PICKit2 programmer to make it self and easier to prototype.

Circuit Design

I use Proteus VSM to design the schematics for this board. Most of parts are already have in Protues while other parts are downloaded from snapeda website.

I putted some major modules on this board:

1. PICKit2 programmer
2. dsPIC30F2010 and dsPIC30F1010 IC socket
3. RS-232 to TTL converter
4. ADC inputs
5. Switches inputs,
6. LEDs outputs
7. Male header for external connection

I tested this PCBA with my PC program to to the PICKit2 device programmer. Everything works well.

Power Supply Testing

I test it with PICKit2 on host software. It's error free.
 

PICKit2 Software Test

PICKit2 Software

I putted a two-row machine-tool female pin header to optionally place a dsPIC30F1010-30I/SO I soldered on an SMD IC adapter board.

A dsPIC30F2010-20I/SP and a dsPIC30F1010-30I/SP that could fit on this PCBA

 

I needed to remove dsPIC30F2010 from this PCBA first before placing the dsPIC30F1010 chip.

Testing the dsPIC30F1010 on this PCBA

 This chip could programmed with the earlier version of PICKIT programmer, PICKIT2.

If you don't have a USB programmer for the on-board PICKIT2 device programmer. You can use a simple serial port JDM programmer with WINPIC800 PC software. 

 

CCS PICC Sample Code

CCS PICC is very easy to use but we need to pay for license. For beginners with with this embedded C compiler using its project wizard is a good choice.

Using Project 24 Bit Wizard

We can use this wizard for dsPIC30F2010 since it's a 24-bit instruction device. 

LED Blinking Using Wizard - Device Settings

LED Blinking Using Wizard - Blinking Example

 It will generate source code for us.

1. #include <main.h>
2. 
   
3. 
   
4. void main()
5. {
6. 
   
7. 
   
8. 
   
9. //Example blinking LED program
10. while(true)
11. {
12. output_low(LED);
13. delay_ms(DELAY);
14. output_high(LED);
15. delay_ms(DELAY);
16. }
17. 
    
18. }

 Its main.h file is separated from main.c file.

 

1. #include <30F2010.h>
2. #device ICSP=1
3. #use delay(clock=20000000)
4. 
   
5. #FUSES NOWDT //No Watch Dog Timer
6. #FUSES CKSFSM  
7. //Clock Switching is enabled, fail Safe clock monitor is enabled
8. 
   
9. 
   
10. #define LED PIN_D0
11. #define DELAY 1000

In the #use delay directive I have the parameter crystal=20000000 to clock=20000000 to prevent error.

On Board LED Blinking

On this PCBA there are two LEDs connects to RD0 and RD1 respectively. So I wrote a simple PIC24 C program to toggle these two LEDs. 

 

1. #include "board.h"
2. 
   
3. 
   
4. void main()
5. {
6. 
   
7. //Example blinking LED program
8. while(true)
9. {
10. output_low(LED0);
11. output_high(LED1);
12. delay_ms(DELAY);
13. output_high(LED0);
14. output_low(LED1);
15. delay_ms(DELAY);
16. }
17. 
    
18. }

I also separate its board.h header file as lists below.

1. #include <30F2010.h>
2. #device ICSP=1
3. #fuses HS,NODEBUG,NOWDT,PR,CKSFSM
4. #use delay(crystal=20000000)
5. 
   
6. #define LED0 PIN_D0
7. #define LED1 PIN_D1
8. 
   
9. #define DELAY 500
10. 
    

I use its on-board 20MHz crystal oscillator instead of a 10MHz oscillator because I can not use its PLL to get its maximum 20MHz frequency. So this crystal oscillator will directly drive the processor.

Tactile Switches and LEDs

There are two push button connect to RC13 and RC14 of dsPIC30F2010 PCBA respectively. I use software polling from these two switches to toggle two on-board LEDs of RD0 and RD1 respectively. 

1. #include "board.h"
2. 
   
3. 
   
4. void main()
5. {
6. 
   
7. set_pullup(TRUE,PIN_C13);
8. set_pullup(TRUE,PIN_C14);
9. 
   
10. 
    
11. while(TRUE)
12. {
13. //TODO: User Code
14. if(input(SW0)==0){
15. output_toggle(LED0);
16. delay_ms(500);
17. }
18. if(input(SW1)==0){
19. output_toggle(LED1);
20. delay_ms(500);
21. }
22. }
23. 
    
24. }

I also modify its main.h file adding two buttons definition.

1. #include <30F2010.h>
2. #device ICSP=1
3. #fuses HS,NODEBUG,NOWDT,PR,CKSFSM
4. #use delay(crystal=20000000)
5. 
   
6. #define LED0 PIN_D0
7. #define LED1 PIN_D1
8. #define SW0 PIN_C13
9. #define SW1 PIN_C14
10. 
    
11. #define DELAY 500
12. 
    

I don't use ICD feature due to complexity, and I don't this hardware.

RS-232 To TTL UART Converter

I putted a DB9 COM Port connector on this board for device and host PC communication. However I don't use its standard MAX232 level converter. Instead I use transistor level converter. 

This is a sample program for on-board UART.

1. #include "board.h"
2. 
   
3. #use rs232(UART1, baud=9600, stream=UART_PORT1)
4. 
   
5. void main()
6. {
7. long cnt=0;
8. printf("HELLO WORLD!\n\r");
9. printf("Saturady 13 September 2025\n\r");
10. printf("dsPIC30F2010 DIY Prototype Board.\n\r");
11. printf("UART To RS-232 Demo Program\n\r");
12. while(TRUE)
13. {
14. //TODO: User Code
15. printf("Time In Seconds: %Lu \n\r",cnt);
16. output_toggle(LED0);
17. cnt++;
18. delay_ms(1000);
19. }
20. 
    
21. }

 The board.h file is the same as above.

1. #include <30F2010.h>
2. #device ICSP=1
3. #fuses HS,NODEBUG,NOWDT,PR,CKSFSM
4. #use delay(crystal=20000000)
5. 
   
6. #define LED0 PIN_D0
7. #define LED1 PIN_D1
8. #define SW0 PIN_C13
9. #define SW1 PIN_C14
10. 
    
11. #define DELAY 500

It will print the following text. LED connects to RD0 toggle every time the UART send data.

Analog to Digital Converter

There are one potentiometer and LM35 temperature sensor on this PCBA. The following C example use the 10-bit ADC module of dsPIC30F2010 to read the ADC value from these two on-board devices.

The following demo program shows a simple ADC reading and sending data over serial port terminal.

#include "board.h"

void main()
{
   unsigned int16 adc_value = 0;
   float analog=0;
   set_pullup(TRUE,PIN_C13);
   set_pullup(TRUE,PIN_C14);
   output_high(LED0);
   setup_adc_ports(sAN4 | sAN5);
   setup_adc(ADC_CLOCK_INTERNAL | ADC_TAD_MUL_31);
   
   printf("dsPIC30F2010 CCS PICC ADC and UART Example\n\r");
   printf("Using dsPIC30F2010 Prototype Board\n\r");
   printf("Wednesday 10-Sept-2025\n\r");
   printf("**************************************************\n\r");
   delay_ms(100);
   
   while(TRUE)
   {
      //TODO: User Code
      set_adc_channel(4);
      delay_us(50);
      adc_value = read_adc();
      analog = (5.0*adc_value)/1023; 
      printf("AN4: %4d Decimal %f Volts\n\r",adc_value, analog);    
      output_toggle(LED0);
      
      set_adc_channel(5);
      delay_us(50);
      adc_value = read_adc();
      analog = (500.0*adc_value)/1023; 
      printf("AN5: %4d Decimal %f Degree Celsius\n\r",adc_value, analog);
      printf("**************************************************\n\r");
      output_toggle(LED1);
      delay_ms(1000);
   }

}

 I put some definition and declaration in the "board.h" header file.

#include <30F2010.h>
#device ADC=10
#device ICSP=1
#fuses HS,NODEBUG,NOWDT,PR,CKSFSM
#use delay(crystal=20000000)


#use FIXED_IO( D_outputs=PIN_D1,PIN_D0 )
#use rs232(UART1, baud=9600, stream=UART_PORT1)

#define LED0    PIN_D0
#define LED1    PIN_D1
#define SW0   PIN_C13
#define SW1   PIN_C14

#define DELAY 500

 Two on-board LEDs blink every time the ADC reading and data transmitting completed.

 The HD44780 16x2 Character LCD Interfacing

The Hitachi HD44780 industrial standard alphanumeric LCD interfacing is very interesting for most of novice micro-controller programming. However there are many new replacing controller chip for this device that operate in the same way. They are available in many forms and at very low price.

Using The TC1604A-04 16x4 LCM Module 

I have a TC1604A-04 (16x4) LCM module that work in almost the same way. It bases on the HD44780 LCD controller but with 4 lines. We can use CCS PICC "lcd.c" C driver to control this module.

It uses the SPLC780D1 controller IC instead of a conventional HD44780 controller chip. 

The TC1604A-04 Block Diagram

The original "lcd.c" driver file able to handle only two lines of LCD. To control a four-line LCD module we just add the LCD command.

 

TC1604A-04 Display Data RAM (DD RAM)

 We just send the LCD command that's the DDRAM Address of each lines. For instance, the lcd_send_byte(0,0xD0) of "lcd.c" driver set the display line to line 4 of this LCD. I optionally write some macros for new lines and LCD clearance.

Wiring the R/W of LCD to GND 

Using the R/W pin can make the program stuck whenever the LCD has problem, or the LCD is not inserted. However we can connect the LCD R/W pin to GND to send command or data to this character LCD that is most common for most programmer. We don't need to read and wait for LCD respond for polling the LCD busy flag.

So I modify the "lcd.c" C driver to by pass the LCD R/W pin. We just wire this pin to GND. We need to copy the "lcd.c" from "..\Program Files (x86)\PICC\Drivers" to project folder and import it by using the #include "lcd.c" directive.

In project IDE we need to comment out the line while ( bit_test(lcd_read_byte(),7) ) ; and add the delay_us(1000) and delay_us(10) statement. 

Modifying the "lcd.c" driver

 The source code is almost the same but the "lcd.c" locates in project folder.
