Use CH341A to program external Flash (W25Q16JV)

Because I am working on a temperature and humidity meter recently, I use a liquid crystal display, but the image size on the liquid crystal interface is too large and cannot be displayed normally.Considering the use of external Flash for storage, I chose the W25Q16 Flash chip.Note that 16 on the chip means 16M bit, not 16M capacity. The actual capacity of this series of chips is 16/8=2M byte. The burner I use is the CH341A bought by Taobao.As follows:

But the supporting programming software is not enough. It is easier to use the NeoProgrammer below, which supports 1629 kinds of Flash chips.

W25Q16JV chip pin description:

CS: chip select pin, low-level chip works, high-level chip worksStrike, this pin must be connected to GPIO

DO: data output

WP: write protection, low level can only be read, high level is up to youread and write

GND: Ground

DI: data input (receives external commands)

CLK:Clock

HOLD: data pause control, low level means pause, high level work, usually useIf multiple devices share one SPI, if there is only one master and one slave, this pin can be connected to VCC

VCC: 2.7～3.6V
