bug in sleep mode sequence

GoogleCodeExporter commented 9 years ago

In ug_dev_ssd1306_128x64.c, the following code is present.....

static const uint8_t u8g_dev_ssd13xx_sleep_on[] PROGMEM = {
  U8G_ESC_ADR(0),           /* instruction mode */
  U8G_ESC_CS(1),             /* enable chip */
  0x0ae, /* display off */      
  U8G_ESC_CS(1),             /* disable chip */    <--------------------------erroneous code.  This should be U8G_ESC_CS(0)  
  U8G_ESC_END                /* end of sequence */
};

static const uint8_t u8g_dev_ssd13xx_sleep_off[] PROGMEM = {
  U8G_ESC_ADR(0),           /* instruction mode */
  U8G_ESC_CS(1),             /* enable chip */
  0x0af, /* display on */      
  U8G_ESC_DLY(50),       /* delay 50 ms */
  U8G_ESC_CS(1),             /* disable chip */     <--------------------------erroneous code.  This should be U8G_ESC_CS(0)  
  U8G_ESC_END                /* end of sequence */
};
