+# SPI_DEMO
+
+This is Not intended to be a full demo, but a simple example of how to use the SPI interface on the Flipper Zero.
+
+Please see [https://youtu.be/W6bGYZ5PgIc](https://youtu.be/W6bGYZ5PgIc) for a video demo.  
+
+My video this Saturday, Nov 18th 2023,  will cover how to wire the device between the Flipper Zero and the chip that supports SPI, such as the W25Q32.
+
+The connections are:
+- Flipper Pin 2 - MOSI (D0 on the W25Q32)
+- Flipper Pin 3 - MISO (D1 on the W25Q32)
+- Flipper Pin 4 - CS (CS on the W25Q32)
+- Flipper Pin 5 - SCK (SLK on the W25Q32)
+- Flipper Pin 8 - GND (GND on the W25Q32)
+- Flipper Pin 9 - 3V3 (VCC on the W25Q32)
+
+
+The `Hellow-World.sal` file can be viewed using [https://www.saleae.com/downloads/](https://www.saleae.com/downloads/) software.  This is a capture of my W25Q32 chip being read by the Flipper Zero.  The commands were sent using the `SPI Mem Manager` application.  
+
+You can find the `SPI Mem Manager` application at [https://github.com/flipperdevices/flipperzero-good-faps/tree/dev/spi_mem_manager](https://github.com/flipperdevices/flipperzero-good-faps)
