    USB to UART Converter using Microchip MCP2200

    Nowadays USB port is used widely for data transactions between electronic devices and computers. In many scenarios, there is no need to communicate with the USB port directly, therefore electronic designers use USB to UART (RS232-Serial) converter chips, so the USB port is converted to a virtual...

    Problem using UART0 in TM4C123 Tiva C Launch Pad

    I'm trying to interface UART0 with the my laptop using the ICDI the code I used is from Mazidi's book : #include <stdint.h> #include "tm4c123gh6pm.h" void UART0Tx(char c); void delayMs(int n); int main(void) { SYSCTL->RCGCUART |= 1; /* provide clock to UART0 */ SYSCTL->RCGCGPIO |= 1; /*...

    UART or I2C sensor version?

    Hello! The tfmini is an IR lidar sensor. There is a UART and an I2C version, quite at the same price. For my project, I need 2 tfmini hooked up to an Arduino UNO with a +/- 1m cable. I've been doing some tests with 2 tfmini UART versions and it works fine following the example...

    Program controls jumps to interrupt handler after RCSTA1 = 0x90;

    Hey guys, I am using pic18f25k80 microcontroller and XC8 compiler for my development. The control of the program jumps from RCSTA1 = 0x90; to interrupt handler when debugged. The TX1IF flags gets sets every time when RCSTA1 = 0x90;. Any idea guys? #include <xc.h> #define _XTAL_FREQ 8000000UL...

    UART interface with PIC16F886

    I am trying uart serial communication on pIC16F886 . I am using 20Mhz external oscillator frequency.For below code i am getting garbage value. i have tested similar code on PIC18F24K40 where i am using 16Mz internal oscillator where i can able to send and receive data with same hardware . Here...
