![]() ![]() ![]() This IC includes charge pump which can generate RS232 voltage levels (-10V and +10V) from 5V power supply. The most commonly used RS-232 level converter is MAX232. So a voltage or level converter is needed which can convert TTL to RS232 and RS232 to TTL voltage levels. Usually all the digital ICs work on TTL or CMOS voltage levels which cannot be used to communicate over RS-232 protocol. UART (Universal Asynchronous Receiver Transmitter) are one of the basic interfaces which provide a cost effective simple and reliable communication between one controller to another controller or between a controller and PC. ![]() NXP’s ARM7 (LPC2148), ARM Development Kit is proposed to smooth the progress of developing and debugging of various designs encompassing of High speed 32-bit Microcontrollers. The kit supports in system programming (ISP) which is done through serial port. The kit is designed in such way that all the possible features of the microcontroller will be easily used by the students. The ARM7 LPC2148 Development Board is specifically designed to help students to master the required skills in the area of embedded systems. ![]()
