The variables

The Leds status

uint8_t LedG=0; // Led Greem 0==OFF 1==ON
uint8_t LedB=0; // Led Blue 0==OFF 1==ON

The Leds flashing

uint8_t LBflash=0; // Led Blue 0==FlashOFF 1==FlashON
uint8_t LGflash=0; // Led Green 0==FlashOFF 1==FlashON

The underlying variables are used to configure the STM WiFi module.

Remember to configure the parameters in according to your WiFi network.

In particular, be sure to specify:

• RouterName (see the orange line below)
• RouterPW (see the yellow line below – password)

uint8_t TxBuffer_RouterName[] = "at+s.ssidtxt=U739\n\r";
uint8_t TxBuffer_RouterPW[] = "at+s.scfg=wifi_wpa_psk_text,Ria1\n\r";
uint8_t TxBuffer_RouterPotectionMode[] = "at+s.scfg=wifi_priv_mode,2\n\r";
uint8_t TxBuffer_RouterRadioInSTAMode[] = "at+s.scfg=wifi_mode,1\n\r";
uint8_t TxBuffer_RouterDHCPclient[] = "at+s.scfg=ip_use_dhcp,1\n\r";
uint8_t TxBuffer_RouterSaveSettings[] = "at&w\n\r";
uint8_t TxBuffer_RouterSoftReset[] = "at+cfun=1\n\r";

See also the function: ConfigureWiFi The underlying variables are used to test the STM WiFi module.

uint8_t TxBuffer_AT[] = "at\n\r";
uint8_t TxBuffer_FAIL1[] = "+WIND:42:RX_MGMT:";
uint8_t TxBuffer_FAIL2[] = "+WIND:43:RX_DATA:";
uint8_t TxBuffer_FAIL3[] = "+WIND:44:RX_UNK:";
uint8_t TxBuffer_FAIL4[] = "+WIND:34:WiFi Unhandled Event:";
uint8_t TxBuffer_FAIL5[] = "ERROR:";

The RxBuffer; contain the characters received (under interrupt) from USART2 that is connect to STM WiFi module.

uint8_t RxBuffer[RXBUFFERSIZE];

The RXBUFFERSIZE is define in the file: Definizioni.h

Virtual EEPROM emulation address defined by the user: not used in this example .

I left because it can be useful for some future application. For more info see here: http://www.emcu.it/STM32F0xx/STM32F0-USART1-USART2-SysTick-IO/STM32F0-USART1-USART2-SysTick-IO.html
