I've done this with SPI microSD cards, but never with a SPI flash. Is this even possible and if so is there an app note to get started.
Content originally posted in LPCWare by Dore on Thu Dec 12 10:05:01 MST 2013 I am using the Internal Flash of LPC1114FHI33/302 for my data storage (eg., configuration parameters) around 40 bytes. Whenever I would like to update the configuration, I am erasing the sector (page erase is not supported in LPC1114FHI33/302) and writing as page. Do i need to erase the sector everytime before writing the page/data? Is it possible to erase one time and program multiple time (overwritting of the existing bytes) ?
