Trying to use ds1307 with ssd1306 oled #74

VedantParanjape · 2020-04-15T08:11:36Z

Devcie type

ESP32

Framework version

ESP-IDF latest master

Describe the bug
I am using https://github.com/TaraHoleInIt/tarablessd1306 to drive the oled. When i try to use both in the same code, ESP crashes.

Code of ssd1306 driver does not use i2cdev library which is the core of all i2c drivers in this repo.
You can make a pull request to https://github.com/TaraHoleInIt/tarablessd1306 to support usage with esp-idf-lib.

VedantParanjape · 2020-04-15T18:46:16Z

How do i port to use i2cdev?

UncleRus · 2020-04-16T06:28:22Z

See https://github.com/TaraHoleInIt/tarablessd1306/blob/master/ifaces/default_if_i2c.c
Something like

#ifdef CONFIG_USE_I2CDEV_LIB
#include <i2cdev.h>
#endif
...
#ifdef CONFIG_USE_I2CDEV_LIB
static i2c_dev_t dev;
#endif

#ifdef CONFIG_USE_I2CDEV_LIB
    ESP_ERROR_CHECK_NONFATAL( i2cdev_init(), return false );
    memset (&dev, 0, sizeof( i2c_dev_t ) );
    dev.port = 0;
    dev.addr = I2CAddress;
    dev.cfg.sda_io_num = SDAPin;
    dev.cfg.sda_pullup_en = GPIO_PULLUP_ENABLE;
    dev.cfg.scl_io_num = SCLPin;
    dev.cfg.scl_pullup_en = GPIO_PULLUP_ENABLE;
    dev.cfg.master.clk_speed = I2CDisplaySpeed;
    ESP_ERROR_CHECK_NONFATAL( i2c_dev_create_mutex(dev), return false );
#else
    ...
#endif
    return true;
}
...
static bool I2CDefaultWriteBytes( int Address, bool IsCommand, const uint8_t* Data, size_t DataLength ) {
#ifdef CONFIG_USE_I2CDEV_LIB
    NullCheck( Data, return false );
    ESP_ERROR_CHECK_NONFATAL( i2c_dev_take_mutex( &dev ), return false );
    ESP_ERROR_CHECK_NONFATAL( i2c_dev_write_reg( &dev, ( IsCommand == true ) ? SSD1306_I2C_COMMAND_MODE: SSD1306_I2C_DATA_MODE, Data, DataLength ), 
        do { i2c_dev_give_mutex( &dev ); return false; } while (0) );

#else
    ...
#endif
    return true;
}

Of course, you will need the appropriate changes to the Kconfig of ssd1306 driver and its makefiles.

VedantParanjape · 2020-04-17T07:04:53Z

Cool, Thanks for the help.

I will close the issue.

chandanchan0086 · 2021-04-28T11:21:59Z

@VedantParanjape is this issue solved?

now I'm facing the same problem but instead of ds1307, I'm using qmc5883l with ssd1306 OLED.

if you got a solution please help me out with this.

I don't remember, but I ditched that OLED library use u8g2 instead and it works fine with this driver.

chandanchan0086 · 2021-04-28T14:02:54Z

@VedantParanjape thank you for your quick response,

Using any library is ok with me. Finally I need to integrate qmc5883l magneto meter and ssd1306oled.
Is that ok to share sample working code. I really got stuck since am new to esp-idf.
