USB to Serial Adapter / Cable - Experience wanted
« on: April 18, 2007, 05:56:59 am »
HI All in the LPC2000 FLashmagic land,

I am look your experiences using a USB-to-Serial cable and some of the standard LPC2000 development boards from Keil, IAR OLIMEX and Embedded Artist.

Most of these dev boards use  DTR to pull a port pin down to put the LPC2000 in to bootloader mode.

I have heard that some USB-to-Serial Adapters may have RS232 signal timing differences between TxD, RxD, DTR etc.


What is your experince with these adapters?


Regards
Joe

Some work well, some work poorly and some don't work at all. There is a thread in the general support section of this forum where hopefully over time people will post their experiences, but to date there isn't enough data to generate much in the way of conclusions. :(

It's a case of get one and try it.

My own personal experience is that adapters based of ftdi chip work well and those based on the prolific chip work badly.

But YMMV.

All the best.

there is a thread somewhere in this forum re what works and what does not.
