| A question about oled ssd1306 bitmap |
 Posted: Sat Mar 09, 2024 7:17 am |

Good day friends, I am not very experienced about CCS, I want to show the code I created on the Oled SSD1306 screen. I am using the x.115 version of CCS and I am using the 1306 library. The code below does not compile.. image_bits How can I send the code on the screen?
| Code: | static const unsigned char image_bits[] = {0x00,0x00,0x00,
0x00,0x00,0x00,0xfe,0x01,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x80,0x01,0x3e,0x00

0x00,0x00,0x00}; |
The code I sent to the screen
| Code: | | oled_text57(1, 10, image_bits, 1, 1); |

What is oled_text57(????)
Where is the image size?
To send data you should call that table byte by byte.
Something similar like
| Code: |
unsigned int16 x;
for(x=0;x<imageByteCount;x++)
{
imageSenderSub(image_bits[x]);
}
|
That's the basic idea. I don't see that in your code.

A 'link' to the 'driver' you're using would help.
I'll assume the '57' in the function means a 5 pixel by 7 pixel character ?
Probably need a variable that contains the length of the array,so when you make the call, it dumps the entire array to the screen ? |

If that array is not one image and they are several he should use a 2 dimensional array or it could get messy really easy.

| I am not very knowledgeable on this subject. Can you tell me the code to send the above code to the screen? I am using the 1306 library. |

OK, didn't know it was a CCS driver, which you're NOT supposed to post.
So please delete it though one of the moderators may... |

NO, I'm saying you need to delete your POSTING that has the SSD1306 driver in it !
You're not allowed to POST 'drivers' that CCS supplies...it's in the 'rules'. |

| Code: | static const unsigned char wifi[] = {0x80,0x0f,0x00,0x60,0x30,0x00,0x18,0xc0,
0x00,0x84,0x0f,0x01,0x62,0x30,0x02,0x11,0x40,0x04,0x0a,0x87,0x02,0xc4,0x1f,0x01
,0xe8,0xb8,0x00,0x70,0x77,0x00,0xa0,0x2f,0x00,0xc0,0x1d
,0x00,0x80,0x0a,0x00,0x00,0x07,0x00,0x00,0x02,0x00,0x00,0x00,0x00}; |
| Code: | //draw BMP stored in ROM
void SSD1306_ROMBMP(uint8_t x, uint8_t y, rom uint8_t *bitmap, uint8_t w, uint8_t h)
{
for( uint16_t i = 0; i < h/8; i++ )
{
for( uint16_t j = 0; j < (uint16_t)w * 8; j++ )
{
if( bit_test(bitmap[j/8 + i*w], j % 8) == 1 )
SSD1306_DrawPixel(x + j/8, y + i*8 + (j % 8));
else
SSD1306_DrawPixel(x + j/8, y + i*8 + (j % 8), 0);
}
}
} |
| Code: | SSD1306_Begin(SSD1306_SWITCHCAPVCC, SSD1306_I2C_ADDRESS);
SSD1306_Display();
delay_ms(100);
SSD1306_ClearDisplay();
SSD1306_ROMBMP(58, 17, wifi, 19, 15); |
I use the ROMBMP algorithm and a ridiculous shape appears on the screen. How can I send the above static const unsigned char wifi shape to the screen correctly? |

so.. what's stored in the array called 'bitmap'
and
you still haven't deleted the CCS driver in your previous post !!!
If you don't do that soon, you'll be in trouble with the forum !!! |
