hi all
Am trying to make my laptop recognize an virtual SD card (sd card adapter connected to the spi of my microcontroller(PSOC controller)). I have seen many projects where in people have integrated the sd card with microcontroller. but i was not able to make out the response that the sd card is sending back.
One of it says expecting R1 but then what is R1 in terms of value.??
i went through the sandisk manual V1.9 which has he details in some of its registers like csd and csr. how ll i be able to emulate this.??
there is a format for R1 and then are things like payload and the crc.do i need to calculate and send it with every response.??
what are the commands that i should expect and what should i reply to make it recognize it as a SD card.
Plz consider this thread...any help regarding this will be greatly appreciated.
thnks a lot brothers...![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
