On this weekend event "I-O DATA FAIR 2017 in Akihabara", IchigoJam RPi will be showed up!
We're prepareing for the workshop to learn how to enjoy programming for kids!

At last IchigoJam runs on Raspberry Pi 3 by Matta of Natural Style!
"RaspberryPi3用 IchigoJam、I-O DATAフェアにて今週末お披露目!起動2秒で走る1.2GHz BASICプログラムでSense HatをHackしよう! – about yrm"

If you want to use the small monitor via the composit cable, you can make it!

This is an earphone with a controller.

Just connect to a composit terminal.
The terminal spec of Raspberry Pi 3 is VIDEO, GND, AUDIO-RIGHT, AUDIO-LEFT (from the root).

You can control "Raspberry Pi Sense HAT" very easily in IchigoJam BASIC!

If you have own WiFi in the home, using WiFi is one of easy way to create own IoT device. Cheking cat's toilet is first step to look a cat's health! Today I updated its communication device to WiFi.

NekoIoT notices me that a cat go to a toilet.

It's a 450 yen distance sensor same as paprika's eye!

MixJuice is the WiFi module for IchigoJam.
Just stack your IchigoJam and set up.

?"MJ APC *ssid* *password* MJ APC *ssid* *password* '................. 'WiFi connected: ***.***.***.*** 'OK

It succeeded to connect the net! And program as below.

Sakura's IoT Platform is easy way to create IoT also and the easiest way to set up! Just be power it on!

This is a tutorial to use it.

In 27 April at Tokyo, we will hold an IoT event!

IchigoJam for PAL TV / making library in IchigoJam BASIC

2017/04/09 23:55:00
#ichigojam #KidsIT #english 

There are 3 TV types in the world, NTSC, PAL and SECAM. (*see NTSC on Wikipedia)
Now IchigoJam supported PAL TV! (from now only NTSC, selected in Japan)

The 4.3inch mini monitor supports both NTSC and PAL.
A little bit smaller than NTSC version and with 50 frames per second.
So "WAIT 50" means 1 second! (NTSC ver: "WAIT 60" is 1 sec)

10 S="PAL" 20 FOR I=0 TO LEN(S)-1 30 X=4+I*8:Y=10:C=ASC(S+I):GSB@PUTCBIG 40 NEXT 20000 END 20010 @PUTCBIG 20020 FOR J=0 TO 7 20030 LC X,Y+J:N=PEEK(C*8+J) 20040 FOR K=0 TO 7 20050 ?CHR$((1<<(7-K)&N)>0); 20060 NEXT 20070 NEXT 20080 RTN

On IchigoJam 1.2 beta 44 firmware, you can hide after 16385 line to make your library.

LIST 10 S="PAL" 20 FOR I=0 TO LEN(S)-1 30 X=4+I*8:Y=10:C=ASC(S+I):GSB@PUTCBIG 40 NEXT OK

If you want to see library, type with name of library and a comma zero.

LIST @PUTCBIG,0 20010 @PUTCBIG 20020 FOR J=0 TO 7 20030 LC X,Y+J:N=PEEK(C*8+J) 20040 FOR K=0 TO 7 20050 ?CHR$((1<<(7-K)&N)>0); 20060 NEXT 20070 NEXT 20080 RTN OK

DMM 4K monitor can display PAL version of IchigoJam also.
You can download this beta firmware Facebook group "IchigoJam-FAN".
Try your PAL TV and report me!

Manipulate 10 Servos on IchigoJam (PCA9685 via I2C)

It's very easy to manipulate a servo on IchigoJam.

PWM 2,100:WAIT60:PWM 2,200

2 means OUT2, 100 means 0.1msec. You can control from 50 to 200 to manipulate the servo.

OUT2-5 supports PWM command. So you can connect up to 4 servos. Do you want to more? Yes we can!

Use this the kit using NXP PCA9685. You can connect 16 servos to this unit and control by I2C. Maximum capacity to manipulate is 992 servos using 16 units cause each unit can have a I2C slave address.

It's very easy to connect. Connect 5V/SCL/SDA/GND/VCC to same name pin on IchigoJam. And connect servos as many as you want (up to 16).

1 'servo 16 (for ver 1.2beta43) 10 POKE#700,#10,100,#A1 20 IF I2CW(#40,0,#700,1) STOP 30 A=I2CW(#40,#FE,#701,1) 40 A=I2CW(#40,0,#702,1) 50 CLV:N=10 60 M=400:FOR I=1 TO N:[I*2-1]=M:NEXT:GSB@SVO 65 WAIT 30 67 FOR J=1 TO 2 70 FOR I=1 TO N:[I*2-1]=150+RND(600-150):NEXT:GSB@SVO 80 NEXT 90 GOTO 60 100 @SVO 110 CLS:FOR I=1 TO N:LC 10,I*2:?HEX$(I-1),[I*2-1]:NEXT 120 A=I2CW(#40,6,#800,4*N) 130 WAIT30:RTN

This is demo program to manipulate 10 servos (on the movie).
10-40 set the frequency of PWM (have to stop before setting)
60 reset positions
70 set randam positions
100-130 sub function to manipulate servos and show them number

Enlarge Your Storage! 1Mbit EEPROM PCB for IchigoJam

2017/04/07 23:55:00
#ichigojam #maker #english 

IchigoJam can storage your 4 programs. If you want to save more, use a chip of EEPROM!
* EEPROM = Electrically Erasable Programmable Read-Only Memory

CN5 of IchigoJam T supports I2C, so I made a EEPROM board!

How to make a EEPROM board on Upverter.

1. Select the EEPROM from the list (A2 is GND or VCC)
"EEPROM for IchigoJam" on Google Docs spread sheet

2. Draw the circuit

3. Design the PCB

4. Order the PCB (Elecrow, FusionPCB, pcbgogo and so on...)

5. Solder the board!

Let's try to make your original EEPROM board!
Easy first step is just forking this!
