Uart speed problem - 115200bd
can me somebody help with uart - speed?
When I set up the speed of uart to 19200bd, all is ok.
When I set up the speed of uart to 115200, I have a problem with receiving the characters. When I send characters from PC, uart interrupt detects twice more character.
Send from PC: HELLO
Receive in processor: H, null,E,null,L,null,L, null, O, null. Between characters is received the character: 0 (dec). I use the interrupt:RX FIFO not empty.
But in 19200bd, processor does not receive the character 0(dec).
The uart actual speed is 115196bd (The CLK of processor is 48MHz).
I tried to change Oversampling, CLK of processor, Stop bits, but everything does not work.
Thank you for help:)
