Raspberry Pi LCD Module (Manual Mode with wiringPi)

You should initialize LCD device after connect to device.

Raspberry Pi Multifunction Module (Manual Mode with wiringPi)

Raspberry Pi Multifunction Module (Manual Mode with wiringPi)

Instruction about multifunction module.

PWM you can use normal PWM IO but if you want to HOLD after closed module gate, the signal

You should write in main function like this:

ex) RC servo
initPWM(spiChan, 24, 40950, 0, 0, 0); //frequency = 40950/4095 = 10msec
LPC1110 clock = 48MHz
clock/divider = 48MHz/24 = 2MHz
t =Frequency/2MHz = 0.02sec = 20msec
40950 : 20mse = X : Ymsec <-You can calucurate from this in the ratio.

PWMDuty(spiChan, ch, duty);
The duty is available from 1msec(0x7FF) to 2msec(0xFFF) for RC servo

MCU Gear Movies

Controlling Simple arm robot

I used Raspberry Pi,  iPad mini and PHP.

MCU Gear test with Raspberry Pi

Zigbee controled LPC 1114FN28 Tank with MCU Gear.

I try to use Lua script (loop) from my windows note PC.

This is a funny movie, to hack PS VITA.

My friend asked me "FF Thunder Plains (雷平原) are quite difficult to avoid thunder 200 times!".So, she try to make "Automatic Thunder Refuger" with Raspberry Pi , Python and MCU Gear(Board level reconfigurable circuit).

I just teach how to use photo sensor and small RC servo motor with these.
