STM32 FatFS + SD Card Example via SPI interface. Anyway, I agree, it would be a good idea to mention this in the documentation. Size of integer types The FatFs module assumes that size of char/short/long are 8/16/32 bit and int is 16 or 32 bit. c that I'd read was fixed in L4 was missing. First you initialize the SPI and you can use the FatFS functions. The way how Processor Expert components are implemented made it pretty easy to extend the existing FatFS component from using a single drive to a 'multi-drive component': Instead linking to a single 'memory' or 'drive' component, I changed the interface to use a 'list of drives':. Here is where FatFS comes to help! About FatFS. I prefer to use Processor Expert when possible as this will often generate code that is smaller in size than. In another case maybe you need to send chunks of data using SPI. The operation is simple. Watch dog example 1. It can be reading data from the peripheral unit like ADC and writing values to RAM.
