Setting up ISR for use with UART Rx interrupt
EDIT: I figured it out, I should have been calling U1RX_ISR_Start() to properly enable the interrupt rather than calling U1RX_ISR_Enable() alone.
I'm getting started for the first time with using a PSoC 5 (CY8C5668AXI-LP010) and I've got a question about setting up a UART Receive interrupt.
I have the UART present and functional (I.E. UART1_PutString works, so the module is operating) but I'm having a tough time getting the interrupt upon receiving a byte to work correctly.
I currently have the UART module placed and wired. the rx_interrupt signal is wired to an interrupt named U1RX_ISR. This interrupt is of type "Derived". The UART is configured to interrupt on byte received. The buffer sizes for both RX and TX are 4 bytes. In the code, I am enabling U1RX interrupt via the U1RX_ISR_Enable() function. What I am now finding is that sending a character to the UART from my PC is resulting in the code ending up in the IntDefaultHandler. I presume it's some sort of issue with my U1RX_ISR not linking up properly? but in that case, how would I go about configuring this interrupt? Would it be better practice to increase the buffer size and use the internal interrupt?
In the code, I am first calling
This is my first time working with a PSoC, so I'm still unfamiliar with best practices and exactly how to configure interrupts properly.
Thanks in advance for the help.
