WebRC1IF is the uart1 receive interrupt flag which is set high when a new serial byte has been received and is waiting in the receive register RXREG1. This flag is set high on receipt of a byte regardless of whether you are using interrupts or not. WebI am having a problem with the UART on the PIC18F26J50. I am able to transmit data from the PIC correctly, but when I try to receive data the RC1IF is never set, hence I am not able to detect when data is received but when RCREG1 is read it will return the received data correctly... most of the time... The UARt is configured in the following way:
char receiveIncomingData; void interrupt() if(RC1IF bit == 1 ...
WebJan 11, 2024 · On the other hand, the linker does not mind if the variable is incremented or not, or your condition is executed or not. As the first comment suggested, it looks like the code is not being executed, due to a wrong interrupts/uart configuration, hardware, etc... Set a break-point inside the condition (RC1IF_bit) and see what is going on. – WebAnswer to Solved 73 74 75 76 LED=0; while (! PIR1bits.RC1IF) //Wait. This problem has been solved!

WebMar 4, 2024 · TX1IF. TX1IF: EUSART1 Transmit Interrupt Flag bit. 1 = The EUSART1 transmit buffer, TXREG1, is empty (cleared when TXREG1 is written) 0 = The EUSART1 transmit buffer is full. Also, as the interrupt fires immediately when you set TX1IE, you don't have to write to TXREG1, because the interrupt will immediately start the next character, and that ... WebRC1IF is read-only. User software must read RC1REG to clear RC1IF. 2. TX1IF is read-only. User software must load TX1REG to clear TX1IF. TX1IF does not indicate a completed … WebApr 19, 2024 · To get the data we will use the PIC’s UART. To decode the frame, we will use a state machine. IDLE : It’s the default state. When the UART get a FRAME ERROR it means that the ligne state to long at 0. It’s the BREAK. During this period we have to read the 0x00 in the UART until we get a new FRAME ERROR. This happens when we are in the MAB. slow cook risotto recipe
