SDHC card example

Post by **cfbsoftware** » Mon Jun 13, 2016 4:41 am

v6.0 of Astrobe for Cortex-M3 includes the source code of a driver module and demo module showing how to access high-capacity SD (SDHC) cards via SPI1. The driver code is based on the NXP Application Note AN11070: Accessing SDC/MMC card using SPI/SSP on LPC1700, Rev.1 (Jun 1, 2011).

The driver and examples were tested on Embedded Artists LPC1769 LPCXpresso and ARM's LPC1768 mbed boards. We used a microSD adapter card which was actually designed by one of our Astrobe users. Although it was designed specifically for use with the Digilent Arty board for the FPGA RISC5 version of Astrobe it works equally well with these LPC1769 boards. For more details see the message in the Astrobe for RISC FPGA forum: A microSD card adapter for the Arty.
