I hope this is a right community to post this question, I have Atsamd21-Xplained-Pro kit and using MSC (USB) example from the list, I can now able to access SD card content on my computer via USB. I want to change SPI SERCOM port of SD card to another one. How can i change that.?
Can i import this project to Atmel START and re-configure the SERCOM port.? if 'yes' the how.? OR please provide any other better way!
Thank you

I am working on my school project - an infotainment system, and I want to read data from the OBD-II port, using ELM over Bluetooth and display it in React. However, to get any information, you need to send a command. Does anybody know what are the commands for example to get RPM or speed?
And can somebody help me with displaying it in react?
I will appreciate every answer
I am working on a CX3 chip from cypress which has a USB 3.0 connectivity. I need to enumerate the USB to work as a UVC class(video class) and as a serial port simultaneously.
I have seen the USB documents related to the same but those don't clearly explain about how to write one.
The CX3 SDK provides help to generate the USB descriptors for a UVC class but that doesn't give info about how to add the COM port features into it.
So my query is how do you write the descriptor for the same.
Thanks in advance.
Refer to the attached project in this knowledge base article from Cypress - "Using CyU3PDebugPrint API to Send Debug Messages over USB-CDC Interface from FX3 Firmware – KBA231478"
This is a modified version on AN75779. You can compare this project with the original AN75779 appnote firmware available here to see the additions done for adding USB-CDC support in a UVC device.
Hope this helps!
I would like to use an arduino with a bluetooth module to modify the volume and skip songs on my phone.
All the information I found was about how to code an application that would communicate with a device via bluetooth, which isn't what I am looking for. I want to know what protocol I should follow to connect to an android device via bluetooth like a car radio would do.
My goal is to be able to use my device as a remote to control the built-in music application.
I think you are looking for the AVRCP protocol. Please send more info about your hardware so I can digg a better answer (if you need more, anyways...).
I am using the ARM-based microcontroller LPC1769 and the LPCXpresso IDE. I am using an example project for Vcom using USB Device controller in 1769. By default it works at 9600 baud. But I don't understand how to change the baud rate - I want to use it at higher baud rate.
Please define every thing well for better answer, I am providing the computer side answer,
If you are connection with Computer, Its using generic Com port which will be assigned to the device,
now, again if you are using computer, the com port have configuration. go to device manager, and see properties>> Configuration>> there you will see baud rate.
go and change that,
that will do. :)
Edit: Updated with links of support in Driver Side,
I have few link for the same VCP(Virtual Comp Port) Drivers you can use
http://www.ftdichip.com/Drivers/VCP.htm
and Documentation for the same in different different case, please refer documentation first :)

this is all from my side :)
So basically, me and a friend are using the Dragon12-Plus2 board for our class in school, and we are trying to get them to talk via Xbee chips. We have hooked one of them up, and simply need a bit of code to get the Xbee to talk with the board so we can make sure it's in correctly. We are writing in C using Freescale Codewarrior, and as much help as possible is appreciated, especially next steps such as when we hook up the other one, how to get the two to talk and test, etc. They should in theory already be set up as a point-to-point system, but we don't have much experience at this time. Any help would be greatly appreciated
If you configure the XBee modules with "AT mode" firmware, you should be able to use the serial port on the Dragon12-Plus2 board to communicate just as you would with a wired connection.
You'll need to configure both radios with the same PAN ID. Make one a coordinator and the other a router. On the coordinator, configure the DH and DL settings to match the SH and SL settings of the router. You can keep the router's default configuration of using 0 for DH and DL, which tells it to send data to the coordinator.
Do your testing on a PC with a two terminal emulators so you can verify that data sent in on one comes out on the other and vice versa.
Here's an excellent guide from the Digi website on Basic XBee ZB ZigBee (Series 2) Chat which provides more detail and a step-by-step guide for configuring the radios.
