7seg LED simulator for IchigoJam web by WebAssembly x HTML

2017/04/20 23:55:00
#js #IchigoJam #web #english 

IchigoJam web updated to simulate 7-segment LED.

IchigoJam web by WebAssembly *7seg on right top!
IchigoJam web connects a 7-seg LED on HTML through shared memory on WebAssembly.

"LED(7seg) by PCN Kanazawa / LED(7セグ) by PCN金沢@ja"
7-segment LED is one of very popular electronics parts to build devices.

You can control the 7seg LED very easy.


"OUT1,1" to light up a top of LED. OUT1-7 connects each LEDs.


127 means 1111111(binary). So all 7 LEDs lighted up.

"Janken using 7seg LED"

This is the dice program.

10 LET[0],6,91,79,102,109,125 20 OUT[RND(6)]

This is the count down progrom.

10 LET[0],63,6,91,79,102,109,125,39,127,111 20 FOR I=9 TO 0 STEP -1:OUT[I]:WAIT60:NEXT

Let's make it!

Write in C language! The fast web with WebAssembly

2017/04/14 23:55:00
#js #web #english 

Chrome and Firefox support WebAssembly to make fast application on the web!
You can write your web application in C language also!
This is simple demo using shared memory on both JavaScript and WebAssembly.

"WebAssembly test" (src on GitHub)

To set up WebAssembly to your Mac (taking 2 hours and 20GB storage space!!)

1. binaryen (compiler for WebAssembly)

cd *** git clone cd binaryen cmake . && make

*** : your bin path
2. wabt (assembler for WebAssembly)

git clone --recursive cd wabt make cd ..

3. LLVM (takes long time and big storage space!)

git clone cd llvm/tools git clone cd ../projects git clone cd ../.. mkdir llvmtmp cd llvmtmp cmake -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX=/usr/local -DLLVM_EXPERIMENTAL_TARGETS_TO_BUILD=WebAssembly ../llvm make -j 8 sudo make install

4. edit PATH (.profile etc...)

export PATH=***/wabt/out/clang/Debug/:***/binaryen/bin/:$PATH

5. done! Let's make web an app in C!

#define SIZE 10 int mem[SIZE]; int* getMemory() { return mem; } int getMemorySize() { return SIZE; } int calc() { int sum = 0; for (int i = 0; i < SIZE; i++) { sum += mem[i]; } return sum; }

Have you ever wondered whether the bus is crowded or not?
Sabae city started "Count of Bus Passengers Real Time Open Data System".

This is the simple monitor application to look that!

Kids love computers. It spreads them world.

This is a list of educational applications I've made for iPad.

The latest "kanaroma" is the application to learn Roma-ji. Roma-ji is a standard typing Japanese method on the computer. (* different from the smartphone, the flick input method is standard instead in Japan)

You can write Japanese on your IchigoJam with it!

We got a little but strong technic to draw pictures to communicate.
Thank you Tanoue-san!

I updated an app to draw graffiti tool "freepad".

Try to make hardwares not only softwares as engineers!
IchigoJam is the easiest way to start that.
