Hello everyone , I am earth salt .

I got off work at 10:30 last night , Working overtime 5 Hours , Solved a movement flow problem .

Before we solve this problem , I have written the items to be modified .

But after solving three of them , I have a brain stroke , Think the rest is useless , No change .

Three of them :

1   First of all 、 II. After the motor stops , Then turn off the upper chip heating .

2   First of all 、 2. Increase the steps of motor configuration file to three times  23*3 = 69 Step .

3   shielding B、C、D Motion control command of the equipment .

Toss the combination of multiple core boards and multiple configuration files , And fixed a code bug.

Not yet. .

Finally found , Amend Article 4 ： The problem can be solved by shortening the time of two heating .

2

This feeling is too low 了 .

Current control methods , The coupling is very tight .

Take time to learn the abstract syntax tree to implement the controller .

Found a controller code today , Such as the opening picture .

Study hard .

This is my own robot language parser program , I reserve the copyright .

Program function introduction ：

• Realize the compilation of variable files and program files ： utilize flex and bison Tools for lexical and grammatical analysis , Using tree structure to build symbol table and abstract semantic analysis tree , Support data type error 、 Parameter mismatch 、 Variable undefined, etc 10 Judgment and prompt of more than types of lexical grammatical errors ;

• Realize the parsing of sub statements ： Through traversing and recursive semantic analysis tree, we can realize the 10 Other variables define statements and motions 、 Set up 、 system function 、 Process control, etc 30 Analysis of more than control instruction statements .

Work must have a summary , Better to write a public name than a good memory .

I must come on .

Today, a single version of the interface programming has been basically realized .

Modified from the framework of the previous project .

I tried to build from scratch , You will still encounter many pits , Give up from zero to one .

From one to two , It's much easier .

Today, I watched a video of a little brother more than a year ago .

It was very much like me , I am the story of layoffs in Shanghai .

Companies that are open-minded have great vitality , Good at playing , But he is not friendly to Meng Xin .
