    SPI Guide #Introduction WizFi360 operates in SPI slave mode and can be controlled via AT commands. In order to communicate with the MCU, the SPI pins must be connected and set the SPI_EN(PB13) pin to Low for SPI. Refer to Figure 1. WizFi360 Pinout to locate the SPI pins. Set the SPI_INT(PB14) pin to low when the user needs to send data from WizFi360 so that the SPI master can read the data.
  • Page 24 #AT CMD Frame The AT CMD frame reads the TX BUFF AVAIL from the SPI Control Frame and sets the Control Byte as 0x91 during the Control Phase if 0x0002 or bit 2 is high. Then the CMD length is set in units of 4bytes and AT CMD messages are included in the data for transmission. AT CMD reply uses the RX Data Frame method when receiving data.
