Hi all,
I'm trying to WAKE a LM4F232HQD mcu getting a signal from a serial connection, the problem is we design instruments that cannot be open by the user and the program is constantly in Hibernation (RTC) mode so we need to implement a circuit that captures a signal from RX and grounds the WAKE pin (72). We cannot use the sleep mode for power reasons so we can't use serial interrupts.
Does someone tried this already? If you getting a signal from the Serial RX what can happens to multiple WAKE pulses?
I hope someone can help with this.
Thanks
German
