For example, LED is connected to the P0.1 pin, it is not recommended to send the value to the port pin directly, first, we have to declare the pin with another variable then after we can use anywhere in the program. The “sbit” is used for declaring the single PIN of the microcontroller. The program is stored in the RAM of the microcontroller but before writing the program, we must aware of the RAM organization of the microcontroller. It consists of memories, serial communication, interrupts, input/output ports and timer/counters, built into a single integrated chip, which is programmed to control the peripheral devices which are interfaced with it. The 8051 microcontroller is the 8-bit ‘CISC’ architecture. The 8051 microcontrollers has been used in lots of embedded products from small children’s toys to large automotive systems.
The 8051 is a family of the microcontroller, which has been developed by different manufacturers such as Philips, Atmel, dalls, and so on. It is developed by the 8086 processor architecture. The 8051 microcontroller is a basic microcontroller, it is first introduced by the ‘Intel Corporation’ since 1970. Embedded System Introduction to the 8051 Microcontroller The embedded system was first introduced by the 8051 microcontrollers. These types of embedded systems are being used in our daily life such as washing machines and video recorders, refrigerators and so on.
#Saving input from serial uart embedded c program software
The embedded system is defined as the combination of embedded C programming software and hardware part majorly consist of microcontrollers and it is intended to perform the specific task.
