JWoodrell 285 Posted October 31, 2013 Share Posted October 31, 2013 I have done some silly things to these chips in the year or so I have been playing with them. but they always came back, may have needed to reflash the program and recheck connections but they were durable and didn't die. but now apparently in playing with motor driving, a transient spike somewhere has now fried the 430 on the board. when I apply power, it doesn't respond to programming calls from CCS, and it heats up to the touch rapidly. so something internal has gone and melted. I guess this is a sort of milestone of sorts now I have to desolder it and replace it. I just hope it didn't take out the OLEd screen at the same time, I only have 1 more of those left till I have to order more (have a whole stick of processors) i get to look forward desoldering tomorrow i guess [update] as an update, the OLED screen was not killed, however the battery charging chip, and the voltage detect chip both were dead as well, so basically all the chips on the board died at the same time, im guessing that "ground" got pulled to negative voltage showing a large voltage spike to all the chips at the same time.
