I have a problem in coding for RESET IC(hardware watchdog tps3813i50) which is connected to At89c51ed2. Before even thinking of code, you need to describe precisely how the reset IC is connected to the AT89c51ed2. Look at the Datasheets for those chips: http://www.atmel.com/dyn/resou...oc4235.pdf http://www.ti.com/lit/gpn/tps3813i50 The tps3813i50 provides an open-draind active-low reset output; the AT89c51ed2 has an active-high reset input! Please help me in writing Delay functions for toggling the WDI pin of reset ic NO! do not so this! This is not an effective way to use a Watchdog! The tps3813i50 Datasheet said:
To benefit from the window watchdog feature and help the watchdog timer monitor the software execution more closely, it is recommended that the watchdog be set and reset at different points in the program rather than pulsing the watchdog input periodically TI tps3813i50 product page: http://focus.ti.com/docs/prod...13i50.html |
