I can't thank you enough if you help me on my journey to program this nightmare.Developed by Simon Tatham, this is not only considered as a file transfer tool but also as a terminal emulator and serial console. IEC0bits.U1RXIE = 1 // Enable interrupt for UART 1 Receive IEC0bits.U1TXIE = 1 // Enable Transmit Interrupts IPC6bits.U1IS = 0x03 // Set subpriority 3 for UART 1 interrupt IPC6bits.U1IP = 0x07 // Set priority 7 for UART 1 interrupt IFS0bits.U1RXIF = 0 // Clears flag status bit for UART 2 Rx IFS0bits.U1TXIF = 0 // Clears flag status bit for UART 1 Tx U1MODEbits.ON = 0x01 // Enables UART module U1STAbits.URXEN = 0x01 //Enables UART receiver U1STAbits.UTXEN = 0x01 //Enables UART transmitter U1MODEbits.UARTEN = 1 // Turn the peripheral on U1STAbits.UTXISEL = 0x01 // UART interrupt is generated and asserted when all characters have been transmitted U1MODEbits.PDSEL = 0 // 8 bit data, no parity U1MODEbits.BRGH = 0 // 16x baud clock is enabled U1MODEbits.ON = 0 // disables UART module
U1BRG = 0x103 // Sets BRG value to 259 which gives a target baud rate of 9600 (bits/second) INTEnableSystemMultiVectoredInt() // Sets up global interrupts as well as multi vector mode Here's what I'm using: Programmer/Debugger : PICK it 3 Microchip: PIC32MX795f512l Software: MPLAB X IDE V3.55 Compiler: X32 V1.34 USB to UART translator: ULINX Isolate RS 422/485 Code in question: All the efforts over a work period of about 50 hrs (about 6 days) has just lead me to more and more frustration because I see no response from putty that gives me any sign that anything in my code is working. At this point I need some verification that at least some part of my code is correct, and a bit more information to start taking things in the right direction. I've looked online for examples and info of how to program a PIC 32 to do UART, and I've looked at the datasheet for what seems like a million times, and still I've made no progress. UART Transmit to PUTTY on COM1 not working (PIC32MX795f512l)ĭoes anyone on here have any experience with PIC32MX795f512l, and can help me figure out why my code hasn't been working? I just started playing around with PICs about 2 weeks ago so I'm a complete rookie at this stuff, but I have a base understanding of interrupts and I/O.
