The peripheral settings in the described demo are fully working and you can look at them as an example.
It is the I/O management the is still an ongoing part.

You have 2 possibilities: [ol] [*]You use an external 12V power supply and connect the 2 Ground. [*]You power the Flex board with a 12V supply and use the Vout line for the sensor power supply. [/ol] Thr first one is better in term of quality, while the second one is easier because it uses only 1 po...

Cool! Good work! :P

Some issues related with paths have been solved together with the \"C30 3.11b bug\".

Try using the patch that you can find here.

It is a EE 1.4.3 problem with C30 version 3.11. Now it\'s solved and next releases will be bug free.

You\'re right, analog inputs accept only voltages in the 0-3V3 range.

The faster solution is a couple of resistors in order to do a partition. Better solutions are possible with buffers, OA with gain set to 2/3 and so on... It depends from your sensor.

Be careful! If you selected the Microchip compiler inside Eclipse you need to use coff complied libraries.

There are different solutions: [ul] [*]Use the demo board + a EasyBee module; [*]Create an adapter for the MultiBus board + a EasyBee module [*]Use my schematic for the adapter plugin (I\'ll put it in the wiki ASAP) on the Multibus board + a XBee module [*]Create a custom board for the EasyBee modul...

All the jumpers are correct? You tryed to measure the 3.3V and the 5V lines to check is the micro is correctly powered?

It started as a polling demo, then it was extended. It was not finished yet when the kernel was released, then we had the idea of putting devices support in the board level so the demo was not ended. We hope to have the new support in the next release of the kernel.

Come diceva anche Paolo, le soluzioni sono molteplici. Quelle a 2-pin funziona con segnali lenti e/o poco rumorosi. Altrimenti ci si appoggia ad un chip esterno. Nei mesi scorsi, per prove interne, si era parlato sia del modello nominato da te sia di altri chip ma nulla è stato ancora realizzato,...

In the demo folder you also can find the schematich for the homemade board. In that you can spot the resistors with the right placement and value.

You remembered to put the pull-up resistors on I2C bus clock and data lines?

You respected all the init phases? TRISxbits for directions, clock multipliers compatible with the system clock and so on?

Nino

Also the ZigBee \"Wireless Communication using FLEX and ERIKA Enterprise Basic\" application notes has ee_radio_spi.c and ee_radio_spi.h for spi init and communication.

I\'m sorry but the DemoBoard doesn\'t export an I2C bus. One of the channels is used but connected to the DACs.
The only way is to solder 2 wires. The place where doing this is less dangerous is on the connector to the Flex.
