Hello, I'm using owfs to read/write the EEPROM of DS2436 and DS2433 devices. Mostly, this works nice and without problems. However, sometimes wrong data is stored on the EEPROM.
I'm wondering what is the correct procedure to read/write form/to an EEPROM. Is it sufficient to use write() and write 32 bytes for example to pages/page.0? Are there any status information if the last write() was successful? Is owfs doing any checks of CRC and sends messages again to the device or do I have to implement this on my own? It would be nice to verify the written data by reading them back, but it seems to be useless because of the caching mechanism of owfs. I know about the "uncached" directory, but reading from there makes owfs stop working. I can imagine the communication will be more reliable if it is slower. I'm using the w1 kernel driver. Is there an option to change the speed of the bus? Maybe when building owfs? thanks in advance Timo ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
