Hey everybody As it seems, I fried the R/W output pin of my LPC17 (p1.27 of the LPC1769 xpresso). When I moved my Synth from the cardboard housing over to the new wood case, I accidentally plugged the 5V supply into J27 next to J2, the actual supply pins. The 800mA slow blow fuse blew instantly, so I assumed, that I had shorted 5V to GND of J27 but everything except for the fuse was alright. Of course, the move from one housing to the other lead to a lot of cables being too short and a bit of debugging due to shorts with the front panel and so on and so forth. The last thing to do, was to solder a longer cable to the KS0108 compatible GLCD, which at least for me is always a hassle to get the specific pinout as well as pullups, pulldowns and trimmerpots correct. After the first power on, the LCD started up normally with the init text, but then things got bad very quickly. After a couple of seconds, it continuously started looking more like a snow storm with random pixels being on or off, firstly changing, whenever the LCD was updated, but becoming static after a while. Meanwhile, with each power cycle, I either get a blank LCD or the mentioned snow storm. Of course, I doubted my skills first, checked the wiring several times, also changing RST high and low, but nothing helped. For a short time, I also believed that the 45cm long cable was too long, but the internet taught me otherwise. So I was left with two possible root causes, either the LCD has to be broken or the LPC. With the built in testlcdpin function, I was able to find R/W always being high (not mattering if an LCD is connected or not). This leads to my conclusion, that I probably fried the output of the LPC, since the pin is directly connected to the micro controller on the lpcxpresso board. Is there a possibility to assign another pin as the LCD R/W pin in a config file, so I can cut and rerout it to P1.27 on the lpcxpresso board and still be compatible with future updates? If this is not an option, does anybody know if the newly released LPC1769 board is fully compatible with the old version: http://www.mouser.ch/ProductDetail/Embedded-Artists/EAX00242/?qs=sGAEpiMZZMtWuggIubTlfyQKvxcc1sy3C%2fHLDQO4Us4%3d ? Thanks for your help! I am a bit in a hurry to fix this quickly, since I have to give up my electronics lab as soon as possible to make room for our firstborn :-) :-( :-) Cheers, Andy
