HILETGO ESP8266 ARDUINO SD SERIAL
HILETGO ESP8266 ARDUINO SD UPDATE

Using library SPI at version 1.0 in folder: /home/kenc/.arduino15/packages/esp8266/hardware/esp8266/3.0.2/libraries/SPI Using library RTClib at version 2.1.1 in folder: /home/kenc/Arduino/libraries/RTClib Using library Wire at version 1.0 in folder: /home/kenc/.arduino15/packages/esp8266/hardware/esp8266/3.0.2/libraries/Wire Using library Adafruit BusIO at version 1.14.1 in folder: /home/kenc/Arduino/libraries/Adafruit_BusIO Not used: /home/kenc/.arduino15/libraries/SD Is there a different set of Libraries I should try? I get a bit confused over different libraries (sometimes the same name? I wish they would include the github address in each to know for sure), and different boards require different libraries, and it looks like some are in the core, or one library loads another? Here's my compiler verbose output for libraries, does this help? Multiple libraries were found for 'SD.h' All boards and libraries in use show to be up to date. Yes, I recently updated to IDE 2.1.0, and all the work I've done on this is on that version (App Image on Linux).

The RTC gives good values with the SDCARD code blocked out after the “File myFile ” declaration.įYI, I only need to read the SDCARD on boot, and never need to write to it (I'm using it for a config file that I'll create/save on a computer). Then I read/print the current time from the RTC, then set it to a dummy time of 3 04:05:06, read it back, then go into the main loop to read/print the RTC every 10 seconds. I then do an “SD.begin” and read a file from the SDCARD, then close the file. My stripped down code loads those libraries, declares a “File myFile “ for the SDCARD, and “RTC_DS3231 rtc ” for the DS3231, a 10 second delay to allow me to start the Serial Monitor. The RTC works in sketch “RTC_NO-SD_AFLIB_v002”, but fails in sketch “RTC_SD_AFLIB_v002”. DS3231S RTC I2C address 0圆8, EEPROM 0x57Īs stated, I can get either to work independently in my code, but enabling the SDCARD /breaks/ the RTC, I just get odd results from the RTC. I was confused by which libraries to use, but after much reading I settled on: #include VSS/GND (Pin 6) GND Pin 3 or Pin6 of SD Card to GND VSS (GND) (Pin 3) GND Pin 3 or Pin6 of SD Card to GND
