On each side of the square (PCB) I've placed pads which are connected to the 4 UART interfaces of the MCU in such way, that you can connect 2 PCBs on any side. Programming PIC Microcontroller for UART Communication: Like all modules (ADC, Timer, PWM) we should also initialize our USART module of our PIC16F877A MCU and instruct it to work in UART 8-bit communication mode. To enable driving the CH340E at high data rates I’ve included an 8MHz HSE oscillator so that the MCU peripheral clocks will be as accurate as they can be. In order to use multiple RS-232 connections on a PIC ® MCU or PIC ® DSC, multiple #USE RS232 pre-processor directives will need to be setup using the STREAM option. The UART module within the Kinetis MCU family of devices allows full duplex, asynchronous, non-return to zero se rial communication between the CPU and remote devices. Installing Atmel Studio 6. • Integrated Level Converter on UART interface and control signals The previous devices would drive the UART and control signals at 5V CMOS logic levels. UART-to-SPI Bridge Using Low-Memory MSP430™ MCUs Figure 2. When the device(MCU) on the left of the above figure sends UART data to wireless module, and the RXD pin of the left wireless module receives the serial port data, it will automatically send the data through the air by means of radio wave. Here USART module of PIC Microcontroller is configured as UART Asynchronous Full Duplex Mode. ATmega32A is talking to the PC via USART(RS232). But this pic has only one USART. UART stands for Universal Asynchronous Reception and Transmission of data serially between two terminals. The EVB main board does not contain an MCU.
