i have a problem using Necto Studio latest version:
i treid many times to use uart3 rx interrupt so when there is data i get interrupt to receive the data through the interrupt handler?
please mikroE i need an example there's no example using necto studio.
Mcu i'm using is mini m4 for stm32 that contains STM32F415RG.
so far i tried to do this but i got error:
Code: Select all
void uart3_config()
{
//init UART
/*UART3_Init_Advanced(115200, _UART_8_BIT_DATA, _UART_NOPARITY,
_UART_ONE_STOPBIT, &_GPIO_MODULE_USART3_PC10_11);*/
uart_configure_default( &uart_cfg );
uart.tx_ring_buffer = uart_tx_buffer;
uart.rx_ring_buffer = uart_rx_buffer;
uart_cfg.rx_pin = PC11;
uart_cfg.tx_pin = PC10;
uart_cfg.tx_ring_size = sizeof( uart_tx_buffer );
uart_cfg.rx_ring_size = sizeof( uart_rx_buffer );
uart_open( &uart, &uart_cfg );
Delay_ms(100);
// enable uart rx interrupt
USART3_CR1bits.RXNEIE = 1;
interrupt_enable(IVT_INT_USART3);// enable interrupt vector
//Enableinterrupts();
}
/*
This is ISR for UART.

Data will be stored in an array buffer until ending line CR or LF
is found then stop and storing incoming data.

}
}Interrupt handler redefined: UART3_IRQHandler at 0x00000037
by the way it works good in mikroc pro for arm but in necto studio it doesn't work.
please i need help i couldn't find any useful solution.
kind regards
