it’s definitely something with the code i can load the example sketch and it works fine plugged into the working design. I appreciate you taking the time to reply. list all files in the card with date and size Serial.println("\nFiles found on the card (name, date and size in bytes): ") Serial.println((float)volumesize / 1024.0) Volumesize /= 2 // SD card blocks are always 512 bytes (2 blocks are 1KB) Volumesize *= volume.clusterCount() // we'll have a lot of clusters Volumesize = volume.blocksPerCluster() // clusters are collections of blocks print the type and size of the first FAT-type volume Serial.println(volume.blocksPerCluster() * volume.clusterCount()) Serial.println(volume.blocksPerCluster()) Serial.println("Although there is a SD card it is not formated correctly") Serial.println("Card failed or not present") If (!card.init(SD_CS)) //it did not see an SD card Root.openRoot(volume) //Open the root directory in the volume. Volume.init(card) //Initialize a volume on the SD card. Serial.println("Initializing SD card.") Ĭard.init() //Initialize the SD card and configure the I/O pins. I included it in case its causing problems void setup() In the hopes of at least seeing the SD card I have also grabbed some code to read the type of SD card until i finish the code for that section. #define IST_Pin 1 // anolog input for DHT11 temp / humid sensorĬonst int OST_Pin = 2 // anolog input pin for outside temp sensorĬonst int SHT_Pin = 3 // anolog input pin for solor heater internal temp these variables are assigning input and out put pins namesĬonst int SD_CS = 8 //CS pin for SD card reader shieldĬonst int DLS_Pin = 0 // anolog input pin for day light sensor asginment LiquidCrystal lcd(2,3,4,5,6,7) // pin assignment for LCD Servo servo2 //create servo object to control the second servo Servo servo1 //create servo object to control the first servo I am using 3.3v as required on the SD shield I do see the LED on the SD shield brighten up when it tries to initialize it if that matters. I have verified none of my hardware by default wants to use an i/o something else is using. I have downloaded and formatted the SD card with the SD Memory Card Formatter I have tried the o/i jumpers as noted above as well as going to pins 11,12 and 13 on the 2560 as the SD shield wants but both ways still show no SD card plugged in Where in lies the problem of it still does not see the SD card. Now that the LCD is moved to pins 28-33 the LCD now correctly displays the no SD card found error like it should. I did originally have the LCD pins d4-d8 on pins 50-53 which I believe is what was causing the garbage to come up on the LCD screen when it failed to see the SD card. Virgin() //this should run the set up if its in the right placeĪs I suggested above I attempted to just jump pins 11, 12, and 13 on the SD shield to pins 50, 51, 52 on the 2560. Serial.println("No Config file found Loading setup") if the file isn't open, then it doesnt exist which means you need to run the setup if the file is available, read from it Serial.println("SD card found") // if did see the SD card #Arduino sd card issues install#don't do anything else you need to install a SD card Serial.println("Card failed, or not present") If (!SD.begin(SD_CS)) //it did not see an SD card see if the card is present and can be initialized: Lcd.begin(16, 2) // set up the LCD's number of columns and rows: Variables assigned in reguards to SD card sheild const int SD_CS = 8 //CS pin for SD card reader shield SPI (SCK on D13, MISO on D12, MOSI on D11, and CS on D8). I suspect I have something coded wrong causing a problem but I am not seeing it. However it is not running the code on the lines directly under that containing: Serial.println(“Card failed, or not present”) I can see the sketch is getting to this line complete code below for review however as far as i can see i am following the example for using the SD shield i have. In the Arduino IDE, go to File > Examples > SD(esp32) > SD_Test, or copy the following code.Working on a HVAC controller and I’m having an issue seeing my SD card. #Arduino sd card issues how to#There are several examples in Arduino IDE that show how to handle files on the microSD card using the ESP32.
