In the same file, insert the following code in the user code area inside the
r_Config_SCI8_callback_receiveend function:
static void r_Config_SCI8_callback_receiveend( void )
{
/* Start user code for r_Config_SCI8_callback_receiveend. Do not edit comment generated here */
/* Check the contents of g_rx_char */
if (( 'c' == g_rx_char) || ( 'C' == g_rx_char))
{
g_adc_trigger = TRUE;
}
/* Set up SCI8 receive buffer and callback function again */
R_Config_SCI8_Serial_Receive((uint8_t * ) & g_rx_char, 1);
/* End user code. Do not edit comment generated here */
}
At the end of the file, in the user code area for adding, add the following function definition:
/*******************************************************************************
* Function Name: R_SCI8_AsyncTransmit
* Description : This function sends SCI8 data and waits for the transmit end flag.
* Arguments : tx_buf -
* transfer buffer pointer
* tx_num -
* buffer size
* Return Value : status -
* MD_OK or MD_ARGERROR
*******************************************************************************/
MD_STATUS R_SCI8_AsyncTransmit(uint8_t * const tx_buf, const uint16_t tx_num)
{
MD_STATUS status = MD_OK;
/* Clear the flag before initiating a new transmission */
gs_sci8_txdone = FALSE;
/* Send the data using the API */
status = R_Config_SCI8_Serial_Send(tx_buf, tx_num);
/* Wait for the transmit end flag */
while (FALSE == gs_sci8_txdone)
{
/* Wait */
}
return (status);
}
/*******************************************************************************
