General discussion / Re: Microchip Arduino thing interview questions?
[quote author="ian"]Audio file, edited to remove banter and cross talk. Unedited audio available if there is a controversy :) Will try to make a smaller embedded version by next week.

Audio sounds quite good, thanks for recording the presentation.

By any chance do you have a link to their Powerpoint slideshow ?

Cheers

[quote author="Zeta"]While Chipkit boards are great some of us already have Pic32 Starter Kits. Will I be able to use The chipkit enabled Arduino enviroment with Pic32 starter kits?[/quote]

As is out of the box probably not. On the PIC32 SKs there is another PIC in the middle serving the USB interface and acting as programmer/debugger, on the other hand the "Arduino like" have a FTDI USB-Serial converter communicating with a serial bootloader preprogrammed on the PIC32MX.

Then to use the Arduino environment you will need at least to add the required hardware and program the serial bootloader on the PIC32MX.

I didn't check yet the code or the new boards (taking for ever to arrive) but I assume that there are no pin or configuration conflicts.

General discussion / Re: Microchip Arduino thing interview questions?
[quote author="schazamp"]I was looking at the schematic and board layout, and it looks like they are using the FTDI FT232RQ (USB to Serial) chip.  My question is, why didn't they use the built-in USB (on the Max32) or one of the PIC-based USB-serial converters (eg., 18F2550, 18F24J50) (for the Uno32 and/or the Max32)?  The PICs seem relatively easy to source, and somewhat cheaper to me.[/quote]

Just to add a datapoint. Microchip has also its own RS232<->USB converter which is the MCP 2200 (based on the PIC18F14K50), simliar to the FTDI chip. Its a fairly new part and there is a breakout board designed by DP but it is not longer available from Seed Studio.

What are Microchip plans to join the open source community and get rid of the developer unfriendly licensing terms included in their application libraries and protocol stacks ?

Clear example USB and TCP/IP, the current terms are very discouraging for freelance developers.

TIA
