I think very nice..

Feb 7,2009 Split SD/MMC

Today, I am split SD/MMC... Oh,,,, nice to looking

Feb 4,2009 JX-MEGA128 + SD Expand

Example 1 for init_SD/MMC and get capacity of card

Download code for study here

Feb 3,2009 SD/MMC Expand to ALL

This board are SD/MMC Slot ,, I am provide

with mcu all Type, Many many time,

You need to study interface SD/MMC

with microcontroller. I think you

have big problem with MCU 5 Volt.

Because SD/MMC only use 3.3 Volt

For my design, Can be use with microcontroller all type i mean 5 volt and 3.3 volt. for 3.3 it no problem. But some

time you need to interface with 5 volt, Just to decreate level voltagte from 5 volt to 3.3 volt.On circuit I have chip

74LVC245for decrease voltage.I am share for all. please load my circuit and make pcb with your self or send to

pcb shop. "My files could you please open by protel99SE or higher tools" .

Feb 3,2009 SD/MMC + GPS + Bluetooth + SMS all in one for security on your car

Now, If you need to find some application for protect your car. Many many time,, after your car parking any where,

WOW ,,, You have to be apprehensive. For my idea,, May be help you. For My application are GPS Data logger

via SD/MMC and check status your car. if youcard have alert. it will be send message via GSM module to your

mobile.And On PCB you can put Bluetooth Device for connect to map on your PDA or your mobile.....i think very

nice for you (sorry as soon as posible update more)

Update Dec 26,2008 MP3 (USB or SD/MMC) I have 2 choice for play,, you can play by USB Drive or SD/MMC

Update Dec 25,2008 MP3 Media (SD/MMC, USB Drive)

Code not finish now

see Video

Update Dec 23,2008 OLED from (ES http://www.es.co.th from thailand and http://www.bolymin.com.tw)

For This OLED it perfect good . if you need to interface with ARM

it OK. But for other MCU, just to use VCC at 3.3 Volt

Download source code for test

For This OLED can be adjust contrast by softwar 256 step

Update Dec 21,2008 look at for Thai language Click

Procedure below are how to make the library file that protected your sourcecode.

For example, I would like to convert the lcd.c function to lcd.lib file for using with the INEX's JX-Mega128 board.
Example Here (link to "Full Code.rar") is a complete lcd.c source code. download for compare St1 and St2

St1. You can make the target library which protected your sorucecode. Any programmer can use your library full

features but do not know your sourcecode.This method is called "Making library file". Normally the makefile

method will create the result file as .hex or .bin for downlaoding to MCU. But with same method you can create

the .LIB file. Please see the example code here.

# Target
TRG = lcdlib <---- create lib file name here (1)

# C-source files
LIBSRC = lcd.c add any files here xxx.c yyy.c (2)

all: $(TRG).lib <---- Target Output (3)

--------------------------------------------------------------------------------------

lcd.o : lcd.c lcd.h makefile (4)

ํyou can add more files here

xxx.o xxx.c xxx.h makefile

yyy.o yyy.c yyy.h makefile

St2.Create your main sourcecode following the example file below. You can add your .lib file into the main code.
In this example you add the lcdlib.lib into the main code. With this method above you an make the C file and

use your library without distribution your library soucecode. Anybody will see the .lib file but do not know your .c

or .h sourcecode.

# Target
TRG = main <--- Output for copy to flash MCU Output = main.hex (1)

# C-source files
SRC = serial.c printf.c $(TRG).c <---- Add any files here jnut.c inex.c (2)

# Libraries
LIB = lcdlib.lib <--- call Lib from step here (3)

#this defines the aims of the make process
all: $(TRG).elf $(TRG).hex <---- Target Output (4)

Thai language Click for look at more detail

With all step above, you can protect your library code and make any custom library for the special one or commercial.

Update Dec 21,2008 ATMEGA8 + RPM Meter. edit from JX-MEGA128. But I use ATMEGA8 + Crystal 8 MHz .PIN PB0 (ICP )

Update Dec 21,2008 JX-MEGA128 + Frequency meter mode ICP capture ,The rang about 1 Hz - 300 KHz ,(jnut test)

download code here . and conect signal from

signal generature (square ware < 5 volt) to PD4,

(ICP1)if you have some advise or any question,,

could you plese send your question to my email

See Video http://www.youtube.com/watch?v=GidvZZX3F20

(The Soundtrack is the Bird in my garden) and

http://www.youtube.com/watch?v=bz3CniOzB-o

Update 20,2008 . Interface JX-128 from inex + Servo motor. The Example is servo turn Left and Turn Right .

if yo need to test, connect Gnd,VCC supply 5 Volt to

Servo motor, For Signal Control connect to PB5,

(PWM5) Turn left and if you need to test for turn right,,,

Connect to PB6 (PWM4)
