LGT8F328P-SSOP20 arduino clone and SPI

Question

LGT8F328P clone I Would like to use the SPI interface.

as indicated on the datasheet:

It has everything necessary but I don't know how to configure <SPI.h>. and how to make it works for example with W5500?

Answer 1

I found out the problem, using LGT8F328P-SSOP20 there are two pins identical! the MOSI on 11 and SS on 10.

in this way I cannot communicate with SPI protocol.

Answer 2

这可能对您有所帮助： https : //github.com/dbuezas/lgt8fx/issues/54其他人通过覆盖 PB0 的默认引脚 IO 方向，使 SPI 在 SSOP20 封装上工作

Answer 3

For W5500 chip, you can using ethernet2 library. Edit the ethernet2.h file for replacing w5500_cspin to 9.

  EthernetClass() { _dhcp = NULL; w5500_cspin = 9; } //default 10
  void init(uint8_t _cspin = 9) { w5500_cspin = _cspin; }

This is specially for LGT8F328P-SSOP20
