Hello
after connecting my lcp1769 to a ULN2803A like on the pic attached it won´t start up anymore. LED2 seems to be be half on and the debugger does not go into main function.
If I disconnect the IC everything starts up fine.
Any idea?
Also If i drive the ULN manually by 3.3V everything is fine which tells me the circuit must be ok....
Is there any special configuration on software side necessary?
Thanks
