A4988 Stepper Motor Driver<\/h2>\n\n\n\n
The A4988 is a complete microstepping motor driver with a built-in translator for easy operation<\/strong>. It is a microstepping driver for controlling bipolar stepper motors which have a built-in translator for easy operation. This means that we can control the stepper motor with just 2 pins from our controller, or one for controlling the rotation direction and the other for controlling the steps. It is designed to operate bipolar stepper motors in full-, half-, quarter-, eighth-, and sixteenth-step modes, with an output drive capacity of up to 35 V and \u00b12 A.<\/p>\n\n\n Note<\/em><\/strong>: We have to connect A4988 driver with external power supply i.e. VMOT<\/strong> pin of driver to +10V of external power supply with the ground connection followed by RST & SLP pins short as shown in circuit diagram.<\/p>\n\n\n\n Now, for powering up the ARIES v2 board via USB port of a Laptop\/Desktop\/PC and burning the code into the ARIES v2 board, we have to use a micro-USB type B to USB type A cable. The cable should be connected to UART0<\/strong> port of the ARIES v2 board, and the Laptop\/Desktop\/PC should be preinstalled with VEGA SDK and Toolchain.<\/p>\n\n\n\n After setting up the toolchain and SDK path environments, clean the executable using make clean<\/strong> command.<\/p>\n\n\n\n Build the example program for Stepper Motor<\/strong> by using make<\/strong> command<\/p>\n\n\n\n Before transferring the built program to board, ensure that you have connected the UART0 connector of the board to the PC.<\/p>\n\n\n\n Open a new terminal, execute the following command <\/p>\n\n\n\n Now you can see the minicom terminal opened and the board UART terminal is ready.<\/p>\n\n\n\n Press Reset Button to set the Aries Board. In the next window, with the space bar select the file stepper_demo_pgm.bin<\/em><\/strong> to be transferred, by pressing Enter<\/strong>, the transfer process starts.<\/p>\n\n\n\n Wait until the process is completed. The screen should display how much data has been transferred.<\/p>\n\n\n\n After completing the transfer the Program will start to execute.<\/p>\n\n\n\n The Motor shaft will start to rotate.<\/p>\n\n\n\n In this tutorial, we will see how we can interface Stepper Motor with Aries v2.0 Board by using A4988 Stepper Motor Driver. Stepper Motor A stepper motor, also known as a step motor or stepping motor, is an electromechanical device that converts electrical power into mechanical power and it is also called as a brushless […]<\/p>\n","protected":false},"author":10,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-1614","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/vegaprocessors.in\/blog\/wp-json\/wp\/v2\/posts\/1614","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vegaprocessors.in\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/vegaprocessors.in\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/vegaprocessors.in\/blog\/wp-json\/wp\/v2\/users\/10"}],"replies":[{"embeddable":true,"href":"https:\/\/vegaprocessors.in\/blog\/wp-json\/wp\/v2\/comments?post=1614"}],"version-history":[{"count":28,"href":"https:\/\/vegaprocessors.in\/blog\/wp-json\/wp\/v2\/posts\/1614\/revisions"}],"predecessor-version":[{"id":2281,"href":"https:\/\/vegaprocessors.in\/blog\/wp-json\/wp\/v2\/posts\/1614\/revisions\/2281"}],"wp:attachment":[{"href":"https:\/\/vegaprocessors.in\/blog\/wp-json\/wp\/v2\/media?parent=1614"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vegaprocessors.in\/blog\/wp-json\/wp\/v2\/categories?post=1614"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vegaprocessors.in\/blog\/wp-json\/wp\/v2\/tags?post=1614"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"\"](\"https:\/\/vegaprocessors.in\/blog\/wp-content\/uploads\/2022\/06\/image-38.png\")
