Well, I’ve discovered three errors in the book:

1. Page 30: The blue bar with PlatformIO commands will appear after creating a new project or open an existing project.
2. Page 173, first line: “main.html” should be “index.html”.
3. Page 180, “Uploading Code”:  One must uplode the code after “Uploading Filesystem Image” on page 181.

Hi.
Thank you for taking the time to telling us about that.
I’ll add that to the errata and it will be fixed on the next eBook update.
The filesystem image can be uploaded before or after the code, it works either way.
Thanks.

Hi Sara and Rui,

Your eBook is really very clear, it is very pleasant to follow all the chapters. All that is proposed works perfectly. Just a few small mistakes. Great job!
Please confirm the code  (page 175):

void initSPIFFS() {
if (!SPIFFS.begin(true)) {
Serial.println(“An error has occurred while mounting SPIFFS”); }
Serial.println(“SPIFFS mounted successfully”); }

The test seems to be bad (always successfull?)

Best regards,
 

Hi.

Yes, you are right.

It always prints the success message. But, if it fails it will print the error message. Not the best test. And it is used in all projects. I’ll need to fix that for the next eBook update.

Thanks for pointing that out.

Thank you for following our work.

Sara

Hi Sara, Rui and everyone, I am following the course with pleasure that I find very interesting, 
I would like to point out that in my case in the exercise on page 112, 
to have the colored border the system suggests this syntax:
Syntax: <line-width> || <line-style> || <color>, 
so I changed the command: 
border: 10px solid # f80d05;
maybe I have a different update of the programs.
I'm happy if this report can be a little help to someone
Keep it up, I like you a lot.

Hi.
It’s deleted.
Thanks for pointing that out. The example should work with either way.
Does the other way work for you too? Or only the “new” one?

Sara
