![]() ![]() PIC is the number one selling chip in the world being selected for new 8-bit designs and used in a wide variety of applications. If(kbhit()): test if a character is ready for getc() function.Our goal at CCS is to provide the customer with the easiest possible solutions for the Microchip PIC MCU development needs. ![]() Putc: send a character over RS232 transmission pin (TX). Printf: sends a string of characters over RS232 transmission pin (TX). For example TX is mapped to pin RD0 and RX to pin RD1: Software UART is generated by the compiler with the same previous function. If the pins TX and RX (RC6 and RC7) are used by an other application we can use software UART. The function #use rs232(UART1, baud = 9600) is used to configure the UART protocol. The code used in this example is shown below. The female COM port is connected to the PC using RS232 cable, this cable has to be male-female because the PC COM port is male. In this example the microcontroller PIC16F887 uses its internal oscillator and MCLR pin function is disabled. This small post shows an example for the usage of the UART protocol with PIC16F887 microcontroller. This module can be used as UASAT or UART. The microcontroller PIC16F887 has a build in USART (Universal Synchronous/Asynchronous Receiver/Transmitter) module.
