rtc libary in visual studio code

[jeroen24]

hey, i am trying to youse the exampel code . but every time i get this error . i think dear is a libary to short in visual studio code but i dont now witch.( i already installed TinywireM).

can enyone help me? this is the errors i get: /home/jeroen/.platformio/lib/TinyWireM_ID797/USI_TWI_Master.cpp: In function 'void USI_TWI_Master_Initialise()': /home/jeroen/.platformio/lib/TinyWireM_ID797/USI_TWI_Master.cpp:64:3: error: 'PORT_USI' was not declared in this scope PORT_USI |= ^ /home/jeroen/.platformio/lib/TinyWireM_ID797/USI_TWI_Master.cpp:66:11: error: 'PIN_USI_SDA' was not declared in this scope << PIN_USI_SDA); // Enable pullup on SDA, to set high as released state. ^ /home/jeroen/.platformio/lib/TinyWireM_ID797/USI_TWI_Master.cpp:69:11: error: 'PIN_USI_SCL' was not declared in this scope << PIN_USI_SCL); // Enable pullup on SCL, to set high as released state. ^ /home/jeroen/.platformio/lib/TinyWireM_ID797/USI_TWI_Master.cpp:71:3: error: 'DDR_USI' was not declared in this scope DDR_USI |= (1 << PIN_USI_SCL); // Enable SCL as output. ^ /home/jeroen/.platformio/lib/TinyWireM_ID797/USI_TWI_Master.cpp:74:3: error: 'USIDR' was not declared in this scope USIDR = 0xFF; // Preload dataregister with "released level" data. ^ /home/jeroen/.platformio/lib/TinyWireM_ID797/USI_TWI_Master.cpp:75:3: error: 'USICR' was not declared in this scope USICR = (0 << USISIE) | (0 << USIOIE) | // Disable Interrupts. ^ /home/jeroen/.platformio/lib/TinyWireM_ID797/USI_TWI_Master.cpp:75:17: error: 'USISIE' was not declared in this scope USICR = (0 << USISIE) | (0 << USIOIE) | // Disable Interrupts. ^ /home/jeroen/.platformio/lib/TinyWireM_ID797/USI_TWI_Master.cpp:75:33: error: 'USIOIE' was not declared in this scope USICR = (0 << USISIE) | (0 << USIOIE) | // Disable Interrupts. ^ /home/jeroen/.platformio/lib/TinyWireM_ID797/USI_TWI_Master.cpp:76:17: error: 'USIWM1' was not declared in this scope (1 << USIWM1) | (0 << USIWM0) | // Set USI in Two-wire mode. ^ /home/jeroen/.platformio/lib/TinyWireM_ID797/USI_TWI_Master.cpp:76:33: error: 'USIWM0' was not declared in this scope (1 << USIWM1) | (0 << USIWM0) | // Set USI in Two-wire mode. ^ /home/jeroen/.platformio/lib/TinyWireM_ID797/USI_TWI_Master.cpp:77:17: error: 'USICS1' was not declared in this scope (1 << USICS1) | (0 << USICS0) | ^ /home/jeroen/.platformio/lib/TinyWireM_ID797/USI_TWI_Master.cpp:77:33: error: 'USICS0' was not declared in this scope (1 << USICS1) | (0 << USICS0) | ^ /home/jeroen/.platformio/lib/TinyWireM_ID797/USI_TWI_Master.cpp:78:17: error: 'USICLK' was not declared in this scope (1 << USICLK) | // Software stobe as counter clock source ^ /home/jeroen/.platformio/lib/TinyWireM_ID797/USI_TWI_Master.cpp:79:17: error: 'USITC' was not declared in this scope (0 << USITC); ^ /home/jeroen/.platformio/lib/TinyWireM_ID797/USI_TWI_Master.cpp:80:3: error: 'USISR' was not declared in this scope USISR = (1 << USISIF) | (1 << USIOIF) | (1 << USIPF) | ^ /home/jeroen/.platformio/lib/TinyWireM_ID797/USI_TWI_Master.cpp:80:17: error: 'USISIF' was not declared in this scope USISR = (1 << USISIF) | (1 << USIOIF) | (1 << USIPF) | ^ /home/jeroen/.platformio/lib/TinyWireM_ID797/USI_TWI_Master.cpp:80:33: error: 'USIOIF' was not declared in this scope USISR = (1 << USISIF) | (1 << USIOIF) | (1 << USIPF) | ^ /home/jeroen/.platformio/lib/TinyWireM_ID797/USI_TWI_Master.cpp:80:49: error: 'USIPF' was not declared in this scope USISR = (1 << USISIF) | (1 << USIOIF) | (1 << USIPF) | ^ /home/jeroen/.platformio/lib/TinyWireM_ID797/USI_TWI_Master.cpp:81:17: error: 'USIDC' was not declared in this scope (1 << USIDC) | // Clear flags, ^ /home/jeroen/.platformio/lib/TinyWireM_ID797/USI_TWI_Master.cpp:82:19: error: 'USICNT0' was not declared in this scope (0x0 << USICNT0); // and reset counter. ^ /home/jeroen/.platformio/lib/TinyWireM_ID797/USI_TWI_Master.cpp: In function 'unsigned char USI_TWI_Start_Transceiver_With_Data(unsigned char*, unsigned char)': /home/jeroen/.platformio/lib/TinyWireM_ID797/USI_TWI_Master.cpp:161:13: error: 'USISIF' was not declared in this scope (1 << USISIF) | (1 << USIOIF) | (1 << USIPF) | ^ /home/jeroen/.platformio/lib/TinyWireM_ID797/USI_TWI_Master.cpp:161:29: error: 'USIOIF' was not declared in this scope (1 << USISIF) | (1 << USIOIF) | (1 << USIPF) | ^ /home/jeroen/.platformio/lib/TinyWireM_ID797/USI_TWI_Master.cpp:161:45: error: 'USIPF' was not declared in this scope

Why are you using TinyWireM? This is a Wire replacement for ATtiny microcontrollers that do not have a real I2C port. It instead relies on the “universal serial interface” (USI) to provide this functionality.

The Uno does not have an USI, but it does have a regular I2C port: you should use the regular Wire library with it. Note that RTClib.cpp uses the TinyWireM library only when being compiled for the ATtiny85, which is clearly not your case.

hey , i am not using the tinywirelibary i just add it the libary. this is the exampel code i am jousing:

include

// Date and time functions using a DS1307 RTC connected via I2C and Wire lib

include "RTClib.h"

RTC_DS1307 rtc;

char daysOfTheWeek[7][12] = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"};

void setup () { Serial.begin(9600);

ifndef ESP8266

while (!Serial); // wait for serial port to connect. Needed for native USB

endif

if (! rtc.begin()) { Serial.println("Couldn't find RTC"); Serial.flush(); abort(); }

if (! rtc.isrunning()) { Serial.println("RTC is NOT running, let's set the time!"); // When time needs to be set on a new device, or after a power loss, the // following line sets the RTC to the date & time this sketch was compiled rtc.adjust(DateTime(F(DATE), F(TIME))); // This line sets the RTC with an explicit date & time, for example to set // January 21, 2014 at 3am you would call: // rtc.adjust(DateTime(2014, 1, 21, 3, 0, 0)); }

// When time needs to be re-set on a previously configured device, the // following line sets the RTC to the date & time this sketch was compiled // rtc.adjust(DateTime(F(DATE), F(TIME))); // This line sets the RTC with an explicit date & time, for example to set // January 21, 2014 at 3am you would call: // rtc.adjust(DateTime(2014, 1, 21, 3, 0, 0)); }

What do you mean by “i just add it the libary”? You should not need to “add” TinyWireM anywhere to compile this example. If you can't prevent platform.io to try to compile it anyway, you should ask for help in a forum dedicated to platform.io.

ok thank you for the help.

@edgar-bonet this is a feature in platformio where all dependancies are compiled, even when dependancies are not referenced in code for a platform, we've let @ivankravets know, for now folks have to manually remove the unused library

[ivankravets]

Sorry for this issue. Please use lib_ignore option and skip libraries from a build process.

This provided some more clarity for me on the TinyWireM issue in VS Code: https://github.com/platformio/platformio-core/issues/3543

Here is an example of the suggested fix in the platformio.ini file:

[env:featheresp32] platform = espressif32 board = featheresp32 framework = arduino lib_ignore = TinyWireM
