i have made some small changes, i put in a 10uF cap between vdd + the mpu, (reset part).

got rid of un-necessary 5volt rego, put in permanent 5 volt and ground references

and named a 100mA fuse in the solar shunt schematic


i think (anfd hope) that should be the final changes to make.......

as for reset watchdogs, after consulting with my tutor, he said whats wrong with what you have,.....i think it will be sufficent for my project.

and the solar shunt circuit will switch off when the battery is fully charged......the output of the battery goes to the op amp 1, and the volatage divider networks see to this......

i still may put in a current limiting ic, not sure.

finally,i cant get the keil to work with a lcd panel, i think i will have to wait for my board to be ready......

thanks for all the positive (and negative!) feedback!
