topic Smart card mode UART in LPC Microcontrollers https://community.nxp.com/t5/LPC-Microcontrollers/Smart-card-mode-UART/m-p/788618#M31718 <HTML><HEAD></HEAD><BODY><P>Hi! I am trying to implement connection with smart card via UART on LPC11uxx. After a few calculation and with help of examples, I understood, that I shlould fill the right values of DLL and DLM to get a nessesary initial frequency (3.57MHz). But, when I configurate DLM = 13 and DLM = 1 using formula Fdiv = SYSCLK/(F*baudrate)&nbsp; (where F = 372 and baudrate = 9600), a see just a 14,5 KHz. Why? Where&nbsp; I made mistake?</P></BODY></HTML> Wed, 31 Oct 2018 09:59:22 GMT rudomanenko 2018-10-31T09:59:22Z Smart card mode UART https://community.nxp.com/t5/LPC-Microcontrollers/Smart-card-mode-UART/m-p/788618#M31718 <HTML><HEAD></HEAD><BODY><P>Hi!
