Hi, I have got 24c00 on my hardware board.Now the problem is that i want it to be read only and any data write should not happen. I cannot edit the program or replace the hardware.Is there in hardware solution to make it write protect on the fly (may shorting pins ). thanks rutu
Not really anything to do with Keil tools, but if you CAN'T change the hardware, why are you asking for a hardware solution? Some serial EEPROM devices have a hardware write protect pin (or write enable), that when connected either high or low will do what you need. You'll need to read the datasheet for your particular device to see if it supports this. Why do people insist on not looking at the datasheets for their hardware?? Or is this an assignment?
"Why do people insist on not looking at the datasheets for their hardware?? Or is this an assignment?" Why should it be any different for an assignment? [rhetorical] Don't they teach students the importance of reading datasheets? [/rhetorical]
hi, I have already seen the datasheet but 24c00 does not have write protoect pin (WP).So i posted it on the forum and also this is not any assignment. Thanks Rutu.
If the device hasn't got a write protect pin, then there's nothing you can do with the hardware to write protect the device. All firmware, I'm afraid.
