Hey guys! I have a problem with the configuration of input for UART in LPC824. I use ringbuffer & interrupt.
(Output work on ewery pin OK.)
Chip_GPIO_SetPinDIRInput(LPC_GPIO_PORT, 0, 17);
Chip_SWM_MovablePinAssign(SWM_U0_RXD_I, 17);
Input does not work. When you use pins P0_10 or 11, 8,1 input work.
When you use pins P0_23, 17, 14, 15 input does not work.
What is the difference between pins?
I tried to disable the default setting pin functions with Chip_SWM_DisableFixedPin() No result :-(
Any idea? Thanks for the help.
