Here are some topics you could explore further: - Timers - How to use the onboard timers for things like blinking LEDs, delays, etc. - A/D Converter - How to read analog sensor values using the analog to digital converter - Serial Communication - How to send/receive data over the serial port - External Interrupts - How to trigger code using external interrupt pins - Memory - Understanding program and data memory limitations - Advanced C Programming - Pointers, structures, functions for more complex programs - Peripherals - Interfacing with additional hardware like buttons, sensors, displays - Projects - Come up with an example project to apply what you've learned

1. PDI Studio 5
Dayna Polstein

2.  Main purpose:
◦ To run programs on devises
 “Mini Computer” – Contains memory space
 Devise for embedded control
 Use a computer to program
 Can download programs from computer
 Can output information to computer
 Contains input/output ports

3.  Everywhere!
◦ Computers
◦ Remote controls
◦ Cell phones
◦ Cars (engine, antilock breaks, cruise control, etc.)
◦ Microwaves
◦ Dishwashers
◦ TVs
◦ DVD Players
◦ Almost every electronic with a user interface

4.  Basic computer skills
 C-programming
 Some basic circuitry

5.  Computer
 C8051 Board
 USB Debug Adapter
 Power Cord
 USB Cable
 SiLabs IDE
 SecureCRT

6. 1.

7. 2. 3.
4.

8.  Used For
◦ Writing Programs
◦ Sending Programs to C8051
 Programmed in C
 Used For displaying text from:
◦ Main Program
◦ Input

9.  Be Careful with circuit
◦ Circuit boards are very delecate
 Only hold circuits by the edges
◦ Do not touch anything metal
 Before setting down:
◦ Make sure rubber feet are in tact
◦ Make sure area is clean and dust-free
 When storing:
◦ Use anti-static bag and cushioned packaging
◦ Store at room temperature

10. To USB
Debug
Adapter
To Power
Cord
LED should light up
when powered

11. USB to
Computer
To power
LEDs should light
outlet
up when in use

12. 1. Open SiLabs IDE
2. Go to File  New File
3. Type in C Program
 Copy Sample Program:
#include <stdio.h>
main ()
{
printf(“PDI Studio 5/n");
}

13. 4. Compile program by pressing the
Assemble/Compile button on the toolbar or
press Project  Assemble/Compile File
5. Build program by pressing the Build/Make
button on the toolbar or press Project 
Build/Make Project
Assemble/Compile Build/Make
Button Button
Note: If your program does not work, it will
notify you at steps 4 and 5 and you will have
to debug before attempting to connect

14. 6. Go to Options  Connection options and
choose USB Debug Adapter and then OK

15. 7. Press the Connect button (or alt c)
Connect
Button
LEDs on the Debug Adapter should now be on

16. 8. Press the Download code button
Download
Code Button

17.  Go to Project  Target Build Configuration
 Enable automatic connect/download after
build and then press build again

18.  Go to C:SiLabsMCUExamplesC8051F02x
 Click on the “Blinky” folder, and open the c
file in IDE
 Press on the green “go” button
 The green led on the board should start
blinking
 Press the red button for the program to stop
 Each program has a description of function
and reason for different lines
 Use these programs as guilds for your
programs

20.  8 ports, 0 through 7
 Each port is 1 byte (8 bits)
wide
 You can address to entire
bytes or individual bits
 Each port can be assigned as
input or output
 C8051 will read the ports as
◦ 0 volts as false
◦ +3 volts as true

21.  Setting by bit (one of eight bits of the port)
◦ To assign b7 of port 0 :
 sbit bit7 = P0^7;
bit7 = 1;

22.  Set as Input
◦ Port 3 pin 7
 P3MDout &= ~0x80;
P3 | = 0x80; *****
 Set as Output
◦ Port 2 pin 2
 P2MOUT |= 0x04

23.  For individual bits, first read entire port, then
use masking to determine value of bit
 Describe Masking Here

24.  Open Secure CRT

25.  Change settings and connect (try different
com numbers) **

26.  Right click on Serial-COM3 and select
“Session Options…”

27.  Click on emulation, change the scrollback
buffer to 32000, and press ok.

28.  Make a new project and file in IDE (save as
384test.c
 Copy this program:
#include "c8051.h"
int main()
{
Sys_Init();
printf("nnntesting...n");
printf("done for now...n");
while(1);
}

29.  Compile and build the code
 Connect and download code
 Start the code
 Text should display on Secure CRT window
