I am creating this project in C language using MPLAB X IDE XC8 compiler. However, you may use any other IDE that works with PIC microcontrollers. In this project, eight LEDs are connected to PORTC of a PIC18F45K22 microcontroller. … Read More
The ADD instruction tells the microcontroller’s CPU to add the source byte to register A and put the result in register A. Recall, A is the accumulator register typically used for all arithmetic and logic instructions.
8-bit microprocessors are limited in their speed (the number of instructions that can be executed in 1 s), directly addressable memory, data handling capability, and so forth. Innovations in semiconductor technology have made it possible for the manufacturers to develop … Read More
The 68HC11 (also abbreviated as 6811 or HC11) is an 8-bit microcontroller that was introduced by Motorola in the year 1984. The production of these chips was later done by Freescale semiconductor. Currently they are fabricated by NXP semiconductors which … Read More
Mutual exclusion typically imposes some conditions on access to a given resource by two or more different processes. For instance, a process can proceed beyond a certain point only after another process has reached some other point of its execution. … Read More
In envisaging a new microcontroller design, it is prudent to follow a design procedure that will take you from the initial problem statement to a programmed microcontroller that can be embedded in application hardware. In this article, we look at … Read More
A field programmable gate array (FPGA) utilizes an array of logic blocks, which can be configured by the user. The term “field programmable” implies that the device is programmable outside the factory where it is produced.
