| SST26 Flash Driver |

Hello
I am looking for a driver for the flash memory SST26. Can I modify the driver from SST26 or has someone modified it?

It would really help if you supplied a link to the device you need the driver for, as well as your PIC type and the compiler version you're using.

It depends what you actually want to do?.
If you are after using it's quad I/O mode, then 'forget it'. This will be slower by a huge margin on a PIC, that just using standard SPI. The PIC doesn't have the hardware to do quad I/O, so you would have to use software, and software SPI at best, will be perhaps 20* slower than the PIC hardware can manage.
If you just want to use it as a simple memory, then one of the existing drivers for same size memory, can be used. The device at boot supports the standard JEDEC commands and these are compatible with for example the MicroChip parts.
The extra security features would not be supported by these drivers, but since they include byte read and write routines, these extra commands could be added fairly easily. |

Thanks a lot for your info. I need a simple memory. I tested with the SST25 Driver from CCS and it works.
Thanks |

Hello, I am trying to make an SST26VF064B running using the sst25vf.c driver but without success.
Did you get an SST26VF0xxB runnung using this code?
Did you do any modifications?
Can you send me a short sample code for testing the memory?
Best regards |

He is the one posting that thread.
I'm very puzzled, because everything says that with certain small limitations,
and a little tweaking the supplied driver ought to be able to work.
Possibly something silly like a faulty chip...  |
