Hi Dialog,
I want to use UART2 to communicate with other device.
But I don't know which port/pin is ready for UART2.
//------------------------------------------------
/* UART 2 */
#if CFG_DEMO_AD_UART
#if dg_configBLACK_ORCA_MB_REV == BLACK_ORCA_MB_REV_D
# define CFG_GPIO_UART2_TX_PORT (HW_GPIO_PORT_4)
# define CFG_GPIO_UART2_TX_PIN (HW_GPIO_PIN_2)
# define CFG_GPIO_UART2_RX_PORT (HW_GPIO_PORT_4)
# define CFG_GPIO_UART2_RX_PIN (HW_GPIO_PIN_1)
#else
Hello MT_dialog,
I'm using uart2 and it seems that the Rx FIFO size is fixed on 16 bytes , is it possible to change it to 32 ? because there is the following struct in uart2.c :
/// FIFO_SZ values
enum UART_FIFOSIZE
{
UART_FIFOSIZE_16,
UART_FIFOSIZE_32,
UART_FIFOSIZE_64,
UART_FIFOSIZE_128
};
But it's not used.
Thanks,

Hi
I am trying to understand how the UART2 Receive interrupt callback flow works, can somebody help me out please?
In the example uart2_async provided in peripheral_examples in SDK 5.0.2.1 , the method UART2_Handler calls uart2_rec_data_available_isr , but I don’t understand what is calling the UART2_Handler method itself.
Also there is a UART2_Handler_func method that doesn’t seem to be defined anywhere. Can someone please shed some light on how this is set up, so I can use it correctly ?
Thanks
Ankit
