  • Looks cool, but the in the tradition of Sparkfun, will a schematic be posted?

  • Trying to use a Raspberry PI to talk I2C to this board to get the device_type. I would expect the value to be 0x0421 per the datasheet, but, I am receiving 0x7400 and wondering what I am doing wrong on reading a simple address:

    Here is my simple code:

    #include <stdint.h>
    #include <stdio.h>
    #include <errno.h>
    #include <stdlib.h>
    #include <wiringPi.h>
    #include <wiringPiI2C.h>
    
    #define I2C_ADDRESS 0x55
    
    
    int main()
    {
        int fd=0;
    
            if ((fd=wiringPiI2CSetup(I2C_ADDRESS)) < 0)
            {
             fprintf (stderr, "Unable to open I2C device: %s\n", strerror (errno)) ;
                 return 0;
            }
            delay(100);
    
            int x4 = wiringPiI2CReadReg16(fd,0x0001);
    
            printf("read from I2C: 0x%04x\n",x4);
    
    return 0;
    }
    

    Output: read from I2C: 0x7400

    Wonder if someone could give me assistances. I want to make sure I understand the I2C communications before trying to incorporate the library.

  • Can someone explain the differential audio output. If I wanted to connect this to a headset speaker (mono), do I need a amplifier or can I do this with discrete parts?

  • Try: http://www.tankzone.co.uk/cart/hl_kt.htm

    They have alot of parts for RC Tanks.

  • Only if I had RFID reader!

  • Have you consider creating a POE 802.1 10/100BT interface blade?

  • I just check Digikey for the mating connector 2.0mm and both H11908CT-ND and H11908TR-ND are in stocked. At time of this posting, they had 8K on hand.

  • Just downloaded the LED library from the top link. I am running Eagle 6.3 on Ubuntu 64 bit machine and I get the following error:

    Loading /Shared/Engineering/eagle/lbr/SparkFun-LED.lbr ...

    Error:

    line 5, column 6: This is not an EAGLE file.

    Thoughts?

  • I am running Ubuntu 10.04.. Seen that before.. I got through digikey.

  • The JST Connector datasheet does not have dimensions. However, the Datasheet has the part number that you can get proper datasheet from Digikey. The 5pin connector is S5B-PH-KS (Digikey: 455-1722-ND)

No public wish lists :(
