very low compilation speed for multi core/thead processors

I performed some test with different computers for a big flowcode program (TCP+LCD+3xADC+RS232) 18Ko compiled size. Here are the results: 1-Samsung NF-210-A-02FR: 6min40s - processor 25% (8min 42s with default settings) 2-ASUS EeePC1201NL: 1min35s - ? 3-Dell OptiPlex 780 MT: 1min15s - processor 50% ...

Re: EB069 WLAN wifi - how to use

Here is a very raw example which show how to use the EB069 without the wifi component. It is very very easy to use because data are send with the RS232 so it is possible to simulate send and receive data. wlan-rs232v2-raw.fcf You can use netstuff to connect to the EB069 wlan and see the effect of tr...

Step 3: Androcar driven by the Android phone tilt

This is an easy Android project. You just need to send the data orientation to the wifi EBlock. I write the orientation on the phone screen but that's not really necessary and that's the most difficult thing to do in the project. It works with just "Hello world" on the screen. Then you jus...

Higher ADC resolution using oversampling:16 bits with 12

It is possible to have more than 1 bit resolution with oversampling 16 bits resolution was possible with a 12 bit ADC in our tests (see text below). A good starting document can be found here : http://www.atmel.com/images/doc8003.pdf For this, the noise must be 1 LSB minimum(least significant bit) W...

Re: FFT on DSPIC

Is it possible to do a 256 buffer-16bits=512 bytes? For a 30F3014, SRAM=2048. This mean 3 buffers and 512 bytes for extra datas. 30F6014 have SRAM=8192 so a 512 byte should be possible(it is 80 tqfp I know). Can the matrix staff do that because a 32bytes buffer is really too short to be used in most...
