I have problem showing a float variable in an Arduino webserver

Weird behaviour while POSTing a JSON through arduino's ENC28J60 module

QUESTION

I have problem showing a float variable in an Arduino webserver

Asked 2021-Apr-27 at 18:06

I am using Arduino Uno, ENC28j60. using rbbb_server example.

the library I am using:

as can be seen in the code below I am trying to convert my Float var to Str using dtostrf() in the homepage function since emit_p() can not accept float vars. although Serial.println(temp1) is working correctly, but in the browser, I have a problem showing the variable(pic added). I've been looking for a solution but couldn't find any, unfortunately. would appreciate any suggestion.

I think I see your problem, but I can't test it.

dtostrf returns a char * pointer to the string you want to print here's the docs

It looks like that function is being called and assigning that string to the temp variable which is a String type (idk your experience, but working with text in Arduino can be very confusing check out this thread ).

Try changing temp1 to be a char * like this:

QUESTION

Weird behaviour while POSTing a JSON through arduino's ENC28J60 module

Asked 2020-Jan-14 at 16:21

I've managed to set up a function to POST JSON data through my Arduino. I'm using webhook to test it and I'm experiencing some weird behaviour with it. The JSON data is not created where I would expect it to. Any help with explaining this would be appreciated.

The Arduino has two completely separate address spaces: program memory, and RAM. Normally, pointers point to RAM.

PSTR("hello") puts the string "hello" into program memory and returns its address within program memory. If you read from this pointer, you actually read from data memory at the same location, and get some completely unrelated data. You need to use pgm_read_byte to read from program memory (which the ENC28J60 library doesn't do).

Your PSTR("") happens to have the same address as the second byte of the string you are printing in setup.

The solution is to remove PSTR() around the POST data.

I'm not sure if it is documented which parameters need to be in program memory, but I found the function here which reads them. It appears that $F means to read a string from program memory and $S means to read a string from RAM. client_postval is read using $S.
