Hello~~ I currently use processing to read the file and then use Serial read () to read documents from arduino, but there is a problem in the data conversion. The following is my data because the ASCII code is read. Currently, there are several methods but still Can't successfully read the value I want, Any suggestions would be greatly appreciated!
新文字文件.txt (724 Bytes)
I am not sure what the problem is. My guess is that you are reading ASCII but want float data type. The atof() function converts ASCII to float. But where does the analogWrite() come in?
It may help if you post your code. Read the how to use this forum-please read sticky to see how to properly post code and some advice on how to ask an effective question. Remove useless white space and format the code with the IDE autoformat tool (crtl-t or Tools, Auto Format) before posting code.
