NETMF Character LCD (C# Code)

I found a usable C# sorec code  for HD44780-compatible Character LCD.
The  BitBucket open source netmf LCD page . has NETMF source code for your projcet.
The online LCD simulator is very useful for you to verify code that you send to LCD.

NETMF C# hardware Watchdog for FEZ Cerb40

Hardware watchdog is very important in industrial control. The FEZ Cerberus main board   /FEZ Cerb40 module are good choose for low cost design. Unfortunately, it is not support watchdog in firmware! (also, The GHI guy said :  Open Source "OSHW" is not support!)

I read the STM32F405 reference manual to find out the solution ... And I try to write the low leve CPU register setting to enable watchdog ...  It is working ! 

The C# source code as follows :
using System;
using Microsoft.SPOT;
using Microsoft.SPOT.Hardware;
using GHI.OSHW.Hardware.LowLevel;
 class iWatchDog
    {
        public uint  TimeOut = 4000; // default 4000 units    
        private uint AccKey = 0x5555;
        private uint RstKey = 0xAAAA;
        private uint EnableKey = 0xCCCC;
        //----------------------------------------------------------------
        Register IWDG_KR  = new Register(0x40003000);
        Register IWDG_PR  = new Register(0x40003004);
        Register IWDG_RLR = new Register(0x40003008);
        Register IWDG_SR  = new Register(0x4000300C);
        //-----------------------------------------------------------------
        public void Init()
        {
            IWDG_KR.Write(AccKey);   // open the access key
            IWDG_PR.Write(4);        // write the Prescaler for 2ms (One unit)
            IWDG_KR.Write(AccKey);   // open again
            IWDG_RLR.Write(TimeOut); // write the down counter  
        }
        //--------------------------------------------------------------
        public void Enable()
        {
            IWDG_KR.Write(AccKey);    // open access key
            IWDG_KR.Write(EnableKey); // enable counter
        }
        //---------------------------------------------------------------
        public void Reset()
        {
            IWDG_KR.Write(AccKey);    // open access key
            IWDG_KR.Write(RstKey);    // reload counter
        }
    }


//--------------------------------------------
// your main program as follows:
//--------------------------------------------.
.
 iWatchDog Wdog = new iWatchDog();
 Wdog.TimeOut = 2500; // for 5 second time out
 Wdog.Init();
 Wdog.Enable();  // enable watch dog
.
.
//-------- the easy way to reset the watchdos counter -----------------
  void timer500_Tick(GT.Timer timer)// 500mS timer tick
  {

             Wdog.Reset(); // reload the watchdog timeout counter
  }

I2C for EEPROM

The  Cerb Family has one I2C interface that connected to socket1 and socket2. I found a very usable code from GHI Electronics . I test the sorce code for 24LC16 eeprom and it is working.
The source code as follows: 
 
//-------------- setup the I2C device ----------------------
I2CDevice EepI2C = new I2CDevice(new I2CDevice.Configuration(0x50, 400)); // 24LC16 Chip @400KHZ clock

//--------------- Write to EEPROM -----------------------
public void EepWrite(int Address, byte data)
        {
            var xActions = new I2CDevice.I2CTransaction[1];
            xActions[0] = I2CDevice.CreateWriteTransaction(new byte[] { (byte)(Address >> 8), (byte)(Address &                 0xFF),data });
            EepI2C.Execute(xActions, 1000);
            Thread.Sleep(5); // Mandatory after each Write transaction !!!
        }
//----------- Read from EEPROM ----------------------
public byte EepRead(int Address)
        {
            var Data = new byte[1];
            var xActions = new I2CDevice.I2CTransaction[1];
            xActions[0] = I2CDevice.CreateWriteTransaction(new byte[] { (byte)(Address >> 8), (byte)(Address & 0xFF) });
            EepI2C.Execute(xActions, 1000);
            Thread.Sleep(5);   // Mandatory after each Write transaction !!!
            xActions[0] = I2CDevice.CreateReadTransaction(Data);
            EepI2C.Execute(xActions, 1000);
            return Data[0];
        }

// Assign the Analog input channel 3 as a Sensor1
  PWM Moto1Pwm = new PWM(Cpu.PWMChannel.PWM_0, 10000, 0.5, false);
// Assign PWM channel 0 as Moto1Pwm output  and working at 10KHz, 50% duty cycle
