Thanks to the FreePCB drawer, I got my hands on a LogicBoost board. I got it build up last weekend, and after discovering that I need to swap RX and TX on my launchpad it worked without problems (it's a 1.3 version which doesn't work with the hardware UART ouf-of-the-box). I have written up a blog post
about it, with more detail of the build and some pictures. Here just the one from the build:
Next step will be building a USB-to-UART cable, to have it connect faster than 9600 baud. My main gripe is that the FTDI header doesn't use the Vcc pin, so I cannot power the board via USB in an easy way (an additional connector to the power pins is needed...).
Btw: the baud rate definition in main.c has a small error - the value is defined as int, not as long, so the compiler mangles this when setting a larger value like 115200...
Thanks for this design, it is a neat little board and will be quite useful in my toolbox.
