1 00:00:01,470 --> 00:00:07,440 How can we control the number of steps in a step and what this lecture will explain how to give the 2 00:00:07,440 --> 00:00:14,640 number of steps to a step emoter as its input, we will use the two phase one method to drive this to 3 00:00:14,640 --> 00:00:15,030 promote. 4 00:00:19,250 --> 00:00:24,500 The control of supermoto and integer number as an input defines a number of steps. 5 00:00:25,730 --> 00:00:33,350 Also, I one with put sends the Sakar man to the mod, therefore when they stop and what a driver receives 6 00:00:33,350 --> 00:00:40,160 a signal pulse on the starting point, it should load the number on its impact and use that as the initial 7 00:00:40,160 --> 00:00:46,210 value for a counter register to count the number of states in the FSM implementing its behavior. 8 00:00:51,550 --> 00:00:57,880 Before writing the code, Etchells, let's have a look at the final design in Vivaan, the design consists 9 00:00:57,880 --> 00:00:58,870 of four ipis. 10 00:00:59,200 --> 00:01:01,530 The main IP is the stepmonster driver. 11 00:01:02,170 --> 00:01:08,920 This IP has a 16 bit input which will be connected directly to slide switches on the basis rebought. 12 00:01:09,310 --> 00:01:14,470 It also has to a single bit inputs motorcoach right and load. 13 00:01:14,860 --> 00:01:19,500 Whereas the motorcoach right defines the speed of going from one step to the next. 14 00:01:19,870 --> 00:01:25,600 The load signal will come on the motto to read the number of steps input and it starts the rotation. 15 00:01:26,930 --> 00:01:34,130 The stepmother, crockpots, IPE, supplies the motorcoach right signal the answer and pulse generator 16 00:01:34,130 --> 00:01:37,330 epis also connect the loud input to a push button. 17 00:01:41,800 --> 00:01:48,130 Let's start coding, open the White House and create a new project with the name of a Stepa underscore, 18 00:01:48,140 --> 00:01:55,440 malter underscore driver underscore with underscore citral underscore white essentialists then select 19 00:01:55,450 --> 00:02:00,220 astep underscore Märta underscore driver underscore with underscore citral at a top function. 20 00:02:01,060 --> 00:02:04,660 Don't forget to choose the bases rebought as a target FPGA platform. 21 00:02:12,170 --> 00:02:15,440 Download the design files and add them to the created project. 22 00:02:20,900 --> 00:02:28,700 Open the design source file as a two phase one method is selected to provide the motor signals the design 23 00:02:28,700 --> 00:02:36,630 FSM has for states which are defined within enumeration data type, the design top function is defined 24 00:02:36,630 --> 00:02:39,860 with four arguments, three inputs and one output. 25 00:02:41,100 --> 00:02:47,150 To a static, variables are declared to save the designer status and the number of remaining steps. 26 00:02:48,950 --> 00:02:54,920 Two temporary variables are also defined, corresponding to the defined static variables, also, a 27 00:02:54,920 --> 00:03:01,520 temporary variable is defined to keep the intermediate values for the design output values when the 28 00:03:01,520 --> 00:03:02,870 load input signal is high. 29 00:03:03,170 --> 00:03:07,010 The counter should be initialized with the value of their steps input. 30 00:03:07,820 --> 00:03:13,070 Then the states in the FSM check them all to collaborate and the steps counter. 31 00:03:14,190 --> 00:03:19,860 If the clock right is one and they stop Kountouris, not zero, then the counters would be decrement. 32 00:03:20,900 --> 00:03:25,790 The state should be changed and the motor should rotate one step further. 33 00:03:26,860 --> 00:03:30,190 Otherwise, the FSM does not change its state. 34 00:03:31,330 --> 00:03:34,990 Synthesize the code and export the corresponding article IP. 35 00:03:47,780 --> 00:03:53,720 Now around the world and create a new project with the name of a stepa underscore to underscore driver 36 00:03:53,720 --> 00:04:00,050 underscore with underscore on this Gheorghiu and select the basis reboard as a target FPGA platform. 37 00:04:13,940 --> 00:04:15,440 Create a new blog design. 38 00:04:27,250 --> 00:04:29,860 And for Ipis to deliver the repository. 39 00:04:40,800 --> 00:04:47,370 The bouncer pulse generator, a amateur kozakiewicz generator, and the establishment of the Reiber. 40 00:04:54,570 --> 00:04:59,880 Instantiate the pipes and connect them together and change the port's name properly. 41 00:06:22,490 --> 00:06:28,550 Download the consent file from the resources folder attached to this lecture and add that to the project, 42 00:06:29,240 --> 00:06:31,860 then generativity stream and program the board. 43 00:08:14,450 --> 00:08:22,790 Something number 800 or one one zero zero one zero zero zero zero zero in binary on this light switches 44 00:08:23,150 --> 00:08:29,660 and pressed up push button, know that as this angle of this stepper motor into two phase one method 45 00:08:29,780 --> 00:08:41,100 is zero point 45 degree, then 800 multiply zero point forty five equals to 360, which means the step 46 00:08:41,150 --> 00:08:43,370 motor will rotate a complete round. 47 00:08:44,330 --> 00:08:50,120 So different numbers on this light switches and pressed up push button and inspect this supermoto. 48 00:08:55,290 --> 00:09:01,740 The next lecture will go into the details of implementing the one two phase on method in Etchells. 49 00:09:05,100 --> 00:09:11,910 This is our takeaway message, using a counter in the Supermoto, driver FSM enables the precise control 50 00:09:12,180 --> 00:09:13,470 on the state rotation. 51 00:09:18,330 --> 00:09:24,420 Now, the quiz question, what number should be set on this light switches such that the motor rotates 52 00:09:24,420 --> 00:09:26,220 three complete rounds and a half?
