#120003 - bit vank version Responding to: ???'s previous message |
Hello Andy
I am using both BIT bang and Smbus interface since when power fail I want to save my curent reading without any interrupt. for the same thing I get fower fail signal from exterternal watch dog.and for RTC chip i am using smbus interface the. when power fail external watchdog will interrupt the mcu and in that same Isr I am disable the all interrupt and run bit bang code written in ISR will execute. and same curent reading. In SM bus interface I have fear that if my other i2c device are running(ex.RTC) and if poer fail than I may lose my current reading. so I use external interrupt with external watch dog to secure my data. I coplitetted i2c usig bit bang and also SMBUS interface both are working fine. Thanks for all who supported me best regards |
