Compile error arduino mkr 101 wifi

TOMMEHR · January 19, 2023, 2:50pm

Hello!

trying to verify my sketch for my project, i out of a sudden recieve the following error:

/home/builder/opt/libraries/latest/m5core2_0_1_5/src/Fonts/Font16.c:10:10: fatal error: pgmspace.h: No such file or directory

#include <pgmspace.h>

**^~~~~~~~~~~~**

compilation terminated.

Error during build: exit status 1

I do not find the #include command with the pgmspace library and i did not put it in my sketch.

please help!
Thank You

Posting the code you were trying to compile might be a good start.
Don’t forget to use triple backticks at the beginning and end of your code so that it displays correctly.
Triple backticks look like this…

What does your full compilation error say (use triple backticks with this again).

Pete

I’m kinda bored tonight so I did some Googling for you.

As I understand it, font16.c uses PROGMEM (pgmspace.h) for memory handling. According to Arduino Reference it should be called with #include <avr/pgmspace.h> if you have an older IDE.

In font16.c it’s just #include <pgmspace.h> without the avr. Might be worth looking into!

https://www.arduino.cc/reference/en/language/variables/utilities/progmem/

github.com

m5stack/M5Core2/blob/master/src/Fonts/Font16.c

// Font 2

// Comment out for £ sign for character 24
#define TFT_ESPI_FONT2_DOLLAR

// The grave ( ` ) diacritical mark will show as a degree ( ° ) symbol
// Comment out next line to return character 0x60 to the grave accent:
#define TFT_ESPI_GRAVE_IS_DEGREE

#include <pgmspace.h>

// Width has been increased by 1 pixel so pixel lengths are calculated correctly
// for the displayed string

PROGMEM const unsigned char widtbl_f16[96] =  // character width table
    {
        6, 3, 4, 9, 8, 9,  9, 3,   // char 32 - 39
        7, 7, 8, 6, 3, 6,  5, 7,   // char 40 - 47
        8, 8, 8, 8, 8, 8,  8, 8,   // char 48 - 55
        8, 8, 3, 3, 6, 6,  6, 8,   // char 56 - 63

You wrote these lines twice in your sketch:

Oh my… Any use of delay()outside setup() is a capital offence and @PeteKnight will put you on his hit list!

This is the longest, but I suggest you remove all your delays and let the timers do their job.

Thank You distans!

Juraj · January 20, 2023, 8:53am

the problem with your sketch is not a problem with Blynk. you use many libraries and some of them has that error (maybe WidgetRTC)

TOMMEHR · January 20, 2023, 12:41pm

Hi folks
found, that rtc.h was the problem. i hope i dont need it using widgetRTC instead.
Thanks

PeteKnight · January 20, 2023, 12:53pm

Non of this is needed in Blynk IoT
You should read the documentation about how to use RTC in Blynk IoT.

Pete.
