In Topic: When will V4.2 really be released and working?

14 June 2012 - 05:28 PM

I think it comes from your program. I also had a moment or you may not access deployment. When unplug the USB , pc is reboot automatiquely ! (driver problem? OS windows 7 Pro 64-bit + NetduinoPlus + 4.2 framework). I think I found the reason (one reason may be). The way of coded .. I declared a variable within a program interuption (who often call themselves). I exit out of the variable this function and I solved the problem. I think it comes from the action of the watchdog when the memory decreases. The watchdog seems slow. my English is poor, sorry if not understand. Thierry

In Topic: binary number representation in c#

Thank you.
Binary notation, is sometimes handy while writing a code to access a register where each bit to a property.

A simply solution:

        const byte b00000000 = 0x00;
        const byte b00000001 = 0x01;
        const byte b00000010 = 0x02;
        const byte b00000011 = 0x03;
        const byte b00000100 = 0x04;
....

Attachments file for all value;

Use For exemple to circuit test (use class b)..

            i2c_gyro.Write((byte) register.CTRL_REG1, b.b00001111);                    // Turn on XYZ axes
            //  Bit 7, 6:  Output Data Rate Selection      [100Hz, 200Hz, 400Hz, 800Hz]                                                                                       
            //  Bit 5, 4:  Bandwidht selection      [12.5 To 110  fonction ODR selection]                            
            //  Bit 3:  Power Down if 0
            //  Bit 2:  Z Axis Enable
            //  Bit 1:  Y Axis Enable
            //  Bit 0:  X Axis Enable

it' équivalent to:

i2c_gyro.Write((byte) register.CTRL_REG1, (byte) 0x0F);                    // Turn on XYZ axes
