NurseBob 111 Posted April 27, 2017 Share Posted April 27, 2017 I just spent the last two hours trying to figure out why all of the UART-related register code was failing on my 5529LP. After hooking up to a different 5529, where code performed as expected, I finally remembered that several months ago I'd found that one of my LP boards had a "broken" UART/I2C - Of course, I'd not marked the board when I set it aside. Dumb. Board is marked now. It's still useful for other experiments, so I'll keep it on hand; I just won't use it for any comms protocols. dubnet 1 Quote Link to post Share on other sites
Fmilburn 446 Posted April 27, 2017 Share Posted April 27, 2017 A while back I damaged two pins on this board and dutifully marked it on the back. Unfortunately it was only visible from the back. Some time later I picked it up and was trying to use it unsuccessfully. After tearing my hair out for a while I eventually turned it over and noticed the markings. Now it is marked front and back. chicken 1 Quote Link to post Share on other sites
NurseBob 111 Posted April 27, 2017 Author Share Posted April 27, 2017 All too familiar... But at least you marked it! Given that my board was DOA for Rx,Tx, I wonder what the level of production QC actually is. I'm not complaining, especially given the price, just curious. Quote Link to post Share on other sites
veryalive 49 Posted April 28, 2017 Share Posted April 28, 2017 would those have been rev 1.4 -or- rev 1.5 ? just curious as I have both. Thanks Quote Link to post Share on other sites

Thanks That's not a G2 value line board, sounds liek NBob was using a 5529LP as well. So hey guys, this is off topic to the post, but not to the hardware. I'm curious, I've only really used the G2 valueline LP's why would I want to use one of these ? Honest question, not a trick, just curious. Quote Link to post Share on other sites
Fmilburn 446 Posted April 28, 2017 Share Posted April 28, 2017 Mine is Rev 1.6 but I should point out that RX,TX only ceased working when I accidently applied 5 volts to a pin - it worked fine before that. I have several F5529 LaunchPads and all were working on receipt Why use a F5529? The LaunchPad itself Costs $3 more but it is faster, has more memory, more and better peripherals (eg faster UART and higher resolution ADC), has USB, etc. It is easy to use if you are familiar with the G2553 and need the features.

zeke 693 Posted April 28, 2017 Share Posted April 28, 2017 I use the G2553 when the client (who could be me) needs that little amount of resources to get the job done. Essentially, it's all about the cost of the chip during production. Quote Link to post Share on other sites
Nightwatch 0 Posted October 30, 2017 Share Posted October 30, 2017 Hi, I would like to note that if the jumpers are not set right on some boards, the UART pins will be disconnected and won't work. Therefore, a board with bad jumpers setup may appear that UART isn't working. (Board's User's Guide shows the jumpers setup). Quote Link to post Share on other sites
