• (in order to work on ESP8266 + Arduino IDE v1.6.6)
• • add function APPTV_SendKey() to send a specified key
• • add function get32bitToSend() to calculate the 32bit
• • modify values of KEY_XXX (e.g. KEY_UP for 0x05) to use with get32bitToSend()
• • modify timing to send 32bit key
• (checked with ESP8266)
