- /* If you want to use a specific flash device, for example for a custom built
19
- board, first look for it in Adafruit_SPIFlash\src\flash_devices.h
20
- * If it isn't in there you need to create your own definition like the
21
- W25Q80DLX_EXAMPLE example below.
22
- * These definitions need to be edited to match information on the data sheet
23
- of the flash device that you want to use.
24
- * If you are not sure what the manufacture ID, memory type and capacity values
25
- should be, try running the sketch anyway and look at the serial output
26
- * The flash device will report these values to you as a single hexadecimal
27
- value (the JDEC ID)
28
- * For example, the first device on the list - the W25Q80DLX - will report its
29
- JDEC ID as 0xef4014, which is made of these three values:
30
- * manufacturer_id = 0xef
31
- * memory_type = 0x40
32
- * capacity = 0x14
33
- * With this macro properly defined you can then create an array of device
34
- definitions as shown below, this can include any from the list of devices in
35
- flash_devices.h, and any you define yourself here
36
- * You need to update the variable on line 71 to reflect the number of items in
37
- the array
38
- * You also need to uncomment line 84 and comment out line 81 so this array
39
- will be passed to the flash memory driver.

- * Example of a user defined flash memory device:
42
- #define W25Q80DLX_EXAMPLE \
43
- { \
44
- .total_size = 1*1024*1024, \
45
- .start_up_time_us = 5000, .manufacturer_id = 0xef, \
46
- .memory_type = 0x40, .capacity = 0x14, .max_clock_speed_mhz = 80, \
47
- .quad_enable_bit_mask = 0x02, .has_sector_protection = false, \
48
- .supports_fast_read = true, .supports_qspi = true, \
49
- .supports_qspi_writes = false, .write_status_register_split = false, \
50
- .single_status_byte = false, .is_fram = false, \
51
