I am using a v1.2 device. In the SD example you #include a header file called mySD.h but you do not include this library anywhere in the Git project.

According to your device diagram and looking at the ESP32__goodSD.ino source code I see that you have connected the SD card in a non-standard way for the ESP32. For example you use IO15 for MOSI but the standard SD library for ESP32 uses the designated MOSI pin of the ESP32 (IO23) so it would seem your custom mySD library is required to make the SD card work on your device!

Where can I find this library?

kosso commented 6 years ago

Same issue. The file mySD.h does not exist.

kosso commented 6 years ago

I see the files required exist in this library: https://github.com/nhatuan84/esp32-micro-sdcard

But I still cannot get it to work.

Anyone have any idea what the correct pin settings are for the SD.begin() statement?

ririfonfon commented 6 years ago

SD.begin(13,15,2,14) with V1.0 it work.

ririfonfon commented 6 years ago

SD.begin(13,15,2,14) 13=SD3-CS 15=CMD-MOSI 2=SDO-MISO 14=CLK-SCK

kosso commented 6 years ago

@ririfonfon Thanks! That worked on my V1.2.

Now I need the pin numbers for the 3 buttons. Any idea? Thanks.

kosso commented 6 years ago

Update: It's OK. I've discovered through some trial and error that the 3 button pins are (in the orientation of the photo):

LEFT 35
MIDDLE 34 
RIGHT 39

(Note: The examples use M5Stack.h (from a very similar board. Is this a dev version?) which defines BUTTON_A_PIN 39, BUTTON_B_PIN 38 and BUTTON_C_PIN 37 which are wrong (at least for the V1.2 board containing the gyro and fewer physical pins)

ririfonfon commented 6 years ago

yes i use RBD_Button https://github.com/alextaujenis/RBD_Button 35 34 39 but if i use the m5stack.h the screen don't work the screen in the lib. is ILI9341 and on the ttgo ts v1.0 is ST7735

do you have another lib. for the speaker ? or the gpio ?

For the screen, I found the Adafruit_ST7735 library worked with these pin settings :

yes me too the lib. adafruit work i have the buttons, screen, sd. but no speaker

kosso commented 6 years ago

In the TEST_speaker folder, did you update your pin button definitions in Config.h https://github.com/LilyGO/TTGO-TS-V1.2/blob/master/TEST_speaker/lib/src/utility/Config.h

The speaker test uses the incorrect button definitions. But you should still automatically hear a short bit of audio when it starts up. It's working OK for me.

kosso commented 6 years ago

@ririfonfon Try my test sketch here, where I have extracted the relevant bits of code from the M5 library test : https://github.com/kosso/ESP32_TTGO_TFT_SD_Sketches/tree/master/TTGO_Speaker

Galbi3000 commented 6 years ago

I have v1.2 with the 1.88 TFT.

When I did get it working using the ST7735 libraries I found the screen did not display correctly. The graphics demo for TTGO worked but the display was shifted one pixel left and one pixel up with random pixels in the unused edges. I left it at that for a while until I bought 2 screens for other Arduino devices.

While getting those to work I found an excellent TFT library elsewhere on GitHub that is faster than the Adafruit ones and it supports many TFT driver chips in one library.

I decided to try that library with the TTGO and got the same problem of shifted display with random pixels. However, that library has much more support for ST7735 variants, by selecting a non-standard variant I was able to make the screen display correctly.

The library I used is called TFT_eSPI available here To get it to work with my TTGO I made the following changes in the User_Setup.h file:

Make sure it's using #define ST7735_DRIVER
Make sure TFT_WIDTH and TFT_HEIGHT are 128 and 160
THIS IS THE IMPORTANT BIT! Use #define ST7735_GREENTAB2

Use the following values for the ESP32 Dev Board settings:

#define TFT_MISO 19
#define TFT_MOSI 23
#define TFT_SCLK 5
#define TFT_CS 16
#define TFT_DC 17
#define TFT_RST 9

The #define ST7735_GREENTAB2 setting corrected the shifted display without altering the colours. The default is ST7735_BLACKTAB. With those changes to User_Setup.h the TTGO screen works perfectly and is much faster than the Adafruit libraries :)

BorisFR commented 6 years ago

I have found the same info for screen, except I put RST to -1. Do you not if it is possible to put the screen backlight off?

jvhaarst commented 6 years ago

For me the default library works, using this code :

#include "SD.h"
#include "SPI.h"

#define PIN_NUM_MISO 2
#define PIN_NUM_MOSI 15
#define PIN_NUM_CLK  14
#define PIN_NUM_CS   13

void setup() {
    Serial.begin(115200);
    SPI.begin(PIN_NUM_CLK, PIN_NUM_MISO, PIN_NUM_MOSI, PIN_NUM_CS);
    if(!SD.begin(PIN_NUM_CS)){
        Serial.println("Card Mount Failed");
        return;
    }
    uint64_t cardSize = SD.cardSize() / (1024 * 1024);
    Serial.printf("SD Card Size: %lluMB\n", cardSize);
}
void loop() {}

Hi, I am having those issue's also...

My board is this one : https://www.ebay.com/itm/TTGO-T2-ESP32-0-95-OLED-SD-card-WiFi-Bluetooth-Module-/202327971464?_trksid=p2349526.m4383.l4275.c1#viTabs_0

My Arduino IDE is up to date being 1.8.5 I can not find my board in the board manager! COM5 is used and i can upload sketches 16Gb SDHC card in FAT32

I have tried with the basic SD library as provided and got following error "Card Mount Failed" Then i changed SD.begin() to : "SD.begin(5, SPI,1000000)" with no solution to my problems next i've tried the mySD library where is stated :
if (!SD.begin(17, 14, 12, 15)) { Serial.println("initialization failed!"); return; } that turned this error : "Initializing SD card...initialization failed!" Then i used : SD.begin(5, 23, 19, 18) with the same error as output.... after this i used the above mentioned settings : SD.begin(13,15,2,14) still the same error....

Can anyone point me to a solution please?

Grtz, Yves
