Im using LPC812 MAX board,
Initially i have configured the board for two UARTs (UART0 as Debug port and UART1 as external) and it works.
later i m in need of switching the external UART into polling mode (refer to lpcOpen_3_01-> periph_uart_rom_polling)
after that Debug UART stopped working. my suspect is "Init_UART_PinMux" something going wrong here.
i have attached the polling example , please help me asap.
any other good suggestion to communicate with esp8266 without polling ?
