The software required to drive a discrete flash chip with an SPI interface is trivial and very small, as you will soon see. Spi Serial Flash Programmer Schematic Diagram Software Required To These libraries are large and can take up precious EEPROM space on smaller embedded controllers.Ĭompatibility and integration into your build environment may require significant debug. ![]() Software Complexity (Choose: Discrete) The SD flash subsystem commonly relies on the SDFat1632 libraries. While shields provide convenience for prototyping, the final production assembly might not have the budget or the space to include SD hardware.Īn 8-pin DIP package of a discrete flash chip is much easier to drop on a protoboard than an SD shield, assuming your development board even supports a shield. The list below contains a few tradeoffs I think about when I need to decide if I want to use a single 8-pin DIP chip or a full-on SD solution: Hardware Complexity (Choose: Discrete) One way to add SD flash to an Arduino system is to use a shield, such as this one by Seeed Studio (three es) I bought at my local Radio Shack for 15. Many reasons exist to choose a discrete flash chip over an SD subsystem, and vice versa, and youll need to consider these tradeoffs for your design. ![]() ![]() ![]() Spi Serial Flash Programmer Schematic Diagram Software Required To.Spi Serial Flash Programmer Schematic Diagram Download The Data.
