TI MSP-EXP430

Thank you so much for the hints and tips.

Will go through them step by step.

Yes, I was stuck, because one of the two same MSP430 is broken (connects on/off all the time, and could not load new firmware as the other working one, latter also took an example c program and I was able to run that and read the value from a register in CCS, so first tiny experience gained) and will be replaced.

Have not installed energia yet, (for what) is it better than CCS?

Trying to use the LP to read resistance values from sensor into mobile, hence need the ADC of the LP. Must later get rid of all unnecessary parts, anyone know how to do that?

This is my minimal F5510 implementation. A regulator to get the 5V USB down to 3.3V, some transient suppression on the USB lines, some passives and a programming header. (I had more stuff for a NFC reader but have left those out.)

Please somehow get in touch (I could not send a private message to you), if you are interested doing more about it on this project or know someone who could. Thank you.

To send PMs we have to both follow each other and then accept the requests. It's a bit long-winded! Feel free to kick the process of if you want to send me a message. I'm more than happy to give you the odd bit of advice on here. However, I can hardly find enough time to work on my own projects so I definitely won't be able to get involved in another one.

By the way, I think that the phone will have to support USB host if it is to connect to a MSP430. Most older phones don't, but this may have improved over the last few years. You are also likely to find that a phone expects power in on the USB port rather than being able to power an external device.

Thx, "follow" has been initiated, over to you.

Re USB power from a mobile, when connecting a mini-usb-hub, its LED is powered by the phone at least, though have not measured how much can be drawn, perhaps it is far less than 5V 0.5A.
