USB with 3 Serial ports
« on: November 01, 2011, 06:11:54 PM »
Folks,
I am looking for a board solution that can do the following:
1. Receive data on two Serial ports
2. Transmit the received data from the two serial ports over the 3rd Serial port and/or
3. Transmit the received data from the two serial ports over the USB port (CDC).
4. Minimum 4 DIO
5. Minimum 2 Analog inputs

Was looking at the SBC44U, but seems lacking any resources for the serial ports.

Anybody ever tried this? Any help/inputs will be very valuable for me.

Thanks.

Hi, the SBC66EC and soon to be released SBC66ECL have a USB port and 4 USARTs. The sample software shipped with the SBC66EC has a CDC port implemented on the USB. The SBC66ECL is a cheaper version of the SBC66EC, and does not have a DC/DC power supply, RTC and uses a cheaper CPU (128K of flash in stead of 256k). It is powered by USB or a external 5V regulator.

Will also in future be releasing a USB only version of the SBC66EC. No Ethernet, one with USB Host and one with USB Device.

Thanks a lot David! You made my day!!!!.

I've already placed the order for the SBC66EC. Will start the development and will be eagerly wait for the ECL.

I was seriously considering ATXMega as an option and even brought the development kit etc!! Then thought I should give PIC another try. Searched heaps in vain!!!

Good on you!

Cheers,

Hi,
Is the SBC66EC programmable using ICD2? Was reading some posts here where people were having issues with ICD2? Is there any update regarding this?

Cheers,

Hello Joseph

I currently only use the PICKit 3 and ICD 3 for programming and developing code on the SBC66EC. Microchip does not recommend using the PICKit 2 or ICD 2 any more. Sorry, not sure if there are any issues when using it with the ICD2. Before my ICD2's untimely death I was using it, and it worked fine with the SBC66EC board.
