no update really, got some very screwy results going on! PSU reporting increase in current being drawn not much but gone from ~20mA to ~70mA, also cc keeps cutting in on the psu. so something is very not ok! i have a feeling the chip itself is playing up, have tried alot of settings for the OSC and the results dont match what i would expect, for example with pllx4 i still get a square wave of 234kHz watch window reports pll lock on, pllx8 gives me square wave of 1.8MHz so very not correct!. i am aeway tommorow but new chip should be here friday, plan is to redo board and start again. seems very easy to upset these 30f chips!
i want to get OSC sorted so i can move on. as a side plan i will post schematic and pcb layout for the max232 board, i am going to do a pcb for max232 ready for when i try the uart. as the chip has 2 uart i will use both chanels on the 232 chip and 2 sockets etc. so that at least might be useful for someone
