STELLARIS-UEXT adapter for Stellaris launch pad in stock

Image

STELLARIS-UEXT is Texas Instruments Stellaris Launchpad to UEXT adapter.

We have prepared demo code for MOD-GSM, MOD-MP3, MOD-GPS, MOD-TC, MOD-SMB380, MOD-IRDA, MOD-LCD3310 so you can interface these modules from your Stellaris Launchpad.

As Stellaris MCU have two SPI, I2C and UARTs we made the adapter with two separate UEXT connectors so you can connect two independant UEXT modules to it. Each UEXT have power up/down control with MOSFET so you can power up and down UEXT modules connected.

PIC32-PINGUINO is Arduino like board which works with Pinguino IDE.

Several new demo examples are uploaded on our web https://www.olimex.com/dev/pic32-pinguino-otg.html

1. MOD-GPS demo example with our GPS module

2. MOD-CC2450 demo example with our low energy Bluetooth module (still not released on our web 🙂 )

3. SHIELD-EKG-EMG demo example how to interface this shield to Pinguino and measure pulse and muscle activity

4. MOD-MP3-X demo example how to play MP3 files with Pinguino

5. Sending and receiving calls and SMS with MOD-GSM and Pinguino

6. Connecting to Bluetooth enabled devices with MOD-BT and Pinguino

7. Interfacing MOD-ZIGBEE-PIR with Pinguino

8. MOD-RTC real time clock interfacing with Pinguino

9. Reading 13.56Mhz RFID tags with Pinguino and MOD-RFID1365-BOX

all examples have readme.txt inside which explains the functionality

DuinoMite controls MP3 player – Add voice and music to your embedded projects

Image
MOD-MP3-X is smart MP3 player build with VS1053 MP3 decoder and STM32F103RBT6 Cortex M3 microcontroller. It can work in two modes – stand alone MP3 player and Smart MP3 player controllable via RS232. In stand alone mode you can control MOD-MP3-X with slide switch to play/stop forward/reverse and increase / decrease the volume.

In Smart MP3 mode you can load MP3 files on the MOD-MP3-X SD-card if you connect with USB to computer, or you can send commands via RS232.

To play file with Duinomite is very simple you just have to send to MOD-MP3-X via RS232 this message: “PSONGNAME FILE.MP3” and to stop it you should send “C”

MOD-MP3-X responds to the commands and you can play with the different commands using this simple BASIC code:

10 OPEN “COM3:9600” AS #1 ‘open UEXT RS232 port
20 INPUT “CMD: “,CMD$ ‘ask for command
30 PRINT #1, CMD$+CHR$(13); ‘send to MOD-MP3-X + CR
35 PAUSE 300 ‘wait the command to be executed
40 IF EOF(1) THEN 20 ‘if there is response from the MOD-MP3
50 PRINT INPUT$(1,1); ‘read and print it
60 GOTO 40 ‘loop forever

with this code you can check all commands which are written in MOD-MP3-X user manual and see what they do.

OK then let’s write small code which plays the song “DUHAST.MP3” from my SD card when I press DuinoMite-Mini user Button, then to stop the song when the button is pressed again .

the code is:

10 OPEN “COM3:9600” AS #1 ‘open UEXT RS232 port
20 PRINT “PRESS THE USER BUTTON TO PLAY DUHAST.MP3”
30 DO: PAUSE 100: LOOP UNTIL PIN(0)=1 ‘wait button to be pressed
40 PRINT #1, “PSONGNAME DUHAST.MP3” ‘start playing the song
50 PAUSE 1000 ‘wait 1 second
60 PRINT “PRESS THE USER BUTTON AGAIN TO STOP THE SONG”
70 DO: PAUSE 100: LOOP UNTIL PIN(0)=1 ‘wait button to be pressed
80 PRINT #1, “C” ‘stop playing the song
90 CLOSE #1
