Comment on A Library for LTC1665/LTC1660 by Josep Seto

Josep Seto — Mon, 06 Feb 2012 08:13:23 +0000

I have been testing LTC1660 with a PIC micro, but when i load an analog port, the rest lose their settings and show 0 volts. When i send the address b1111, all ports are set correctly but again, when i load one port individually the rest lose their settings.

Have you experienced this behavior?

I have pin CLR always tied to Vcc.

Thanks

Thanks for compiling this info! It was very helpful for me; I’m using the MMA8453Q as well, and your work helped save me a lot of time pouring over the datasheet. I see a lot of interesting articles in your blog and look forward to seeing more about your hobby work. :D

Comment on Arduino Development Using NetBeans by kwong

Hi John,

You will have to add the upload option manually by right clicking on the makefile and choose Make Target->Add Target and add the upload target name. Then you can right click and choose upload to upload the hex file generated.

Thanks for providing a great utility. It all worked fine for me with one exception. I can build hex files but do not get the option to upload them to the board. I get the options to make, make all, make clean and add target. Any suggestions as to what needs changing would be appreciated. I am using Ubuntu 10.4 and Netbeans 7.1.

Comment on A Simple Beowulf Cluster by mike lee

hi, I am a 7th grade math teacher and thought for PI day, it would be fun to try a beowulf cluster to run the computation. I saw there a was a code download that could do that. Have you updated any of your instructions, and do you have any words of wisdom for a linux newbee>

thanks

Have you tried contacting the seller? They have their own site on eBay and they are very responsive.

Comment on RF Data Link Using Si4021 And Si4311 by kwong

Sure thing. You read from the receiver output as you would from an UART output. So if you are testing this with an Arduino, you can simply connect the output from Si4311 to the Rx pin on ATmega328 and use Serial Monitor to see the received data (you will have to set the baud rate to be the same as the transmitter side).

Hi Kerry,
Could you please explain me how to read data from Si4311 receiver?
Thanks,

Comment on TIFF Merge and Split Utility by kwong

I took a look at my original code (it has been a long while), anyway, you will need to supply a path to your output file. For instance:

TiffMS -o c:\temp\out.tiff -m final.tiff final2.tiff

Could you give that a try?

I placed the program files into a c:\tiff directory –> not sure if that’s what you meant by the problem perhaps being a “space in your path.” I also enclosed the file names in quotes. Is that what you meant?

C:\tiff>TiffMS -o “out.tiff” -m “final.tiff” “final2.tiff”

Same error message, I am afraid. :(

It looks like you got a FileNotFound exception, which seems to me could be that your file names have spaces (or space in your path).

I’d put your parameters in quotes and try running again.

Hi Kenny!

I am trying to use your utility to merge two .tiff files, but get the following error message. I am using the command line, with the following command:

C:\Program Files\TIFF Merge Split Utility>TiffMS -o out.tiff -m final.tiff final
2.tiff

Can you see where I might be going wrong? Both .tiff files (final.tiff and final2.tiff) are in the C:\Program Files\TIFF Merge Split Utility directory. Thanks!
