+# MAX7219 8 digit 7 segment display demo
+
+This example for the `max7219_spi_driver` and `max7219_spi_driver_extended` library demonstrates controlling a MAX7219 or MAX7221 based display over SPI with basic and advanced text writing, and at least one example of every available display function in some capacity.
+
+---
+
+The MAX7219 and MAX7221 chipsets are used in many 8 character 7 segment and 8x8 single colour dot matrix displays which can be purchased preassembled on eBay and AliExpress very cheaply. The abundance and low cost of these displays makes them a great companion for small projects requiring a display output that is more capable than single LEDs but not as complex as something like an LCD.
+
+---
+
+The example expects you to connect a MAX7219 based 7 segment 8 character display to your CH32V003 like so:
+- `DIN` / `MOSI` to `PC6`
+- `SCLK` to `PC5`
+- `CS` to `PD0`
+
+You can choose which examples will be shown on the display by changing the `spi_max7219.c` file in the marked demo selection section. All examples are enabled by default.
+
+Once running, you'll see one of the many examples being displayed like so:

+/*
+ * SPI based driver for the MAX7219 display driver (https://www.analog.com/media/en/technical-documentation/data-sheets/MAX7219-MAX7221.pdf)
+ *
+ * The driver can be used for 64 discrete LED control, or for 8 digits of 7 segment (+ decimal) displays. It includes a basic 7 segment display font called Code B
+ * which is made available with this library, as well as various other functions such as multiplexer scan limiting, digital brightness control and font decoding.
+ *
+ * The one-byte segment arrangement in the digit registers appear like so:
+ *
+ * A
+ * ---
+ * F | G | B
+ * ---
+ * E | | C
+ * ---
+ * D . DP
+ *
+ * +-----+----+----+----+----+----+----+----+----+

+ * +-----+----+----+----+----+----+----+----+----+
+ * | Seg | DP | A | B | C | D | E | F | G |
+ * +-----+----+----+----+----+----+----+----+----+
+ *
+ * On standard 8 digit boards, the 0th digit (MAX7219_REGISTER_DIGIT0) is on the right and the 7th digit (MAX7219_REGISTER_DIGIT7) is on the left.
