ILI9341 SPI atmega8, big font

01.07.2020, 21:07. Просмотров 162. Ответов 1

Здравствуйте, у меня возник вопрос - как вывести 24 битный шрифт на дисплей?
Двухмерный массив символов 16 битного шрифта я нашел и успешно реализовал в коде.
В инете нашел только одномерный массив и очень громоздкий который не помещаться в память меги8.
Подскажите, где можно найти двухмерный 24 битный массив?

Если кому надо, знакогенератор под 16 бит символы:
C++
1

void TFTDrawChar(int x, int y, uint16_t color, uint16_t phone, unsigned char char)
{
            unsigned int i,h;
            LCD_SetCursorPosition(x,y+2,x+7,y+15);
            DC_LOW;
            TFT9341_SendCommand(0x2C);
            DC_HIGH;
            CS_HIGH;
            for(h=0;h<16;h++)
            {
                for(i=0;i<8;i++)
                {
                    if ((pgm_read_byte(&chars16[char-0x20][h])>>(7-i))&0x01)
                    {
                                                TFT9341_SendData(color>>8);
                                                                        TFT9341_SendData(color);
                    }
                    else
                    {
                                                TFT9341_SendData(phone>>8);
                                                TFT9341_SendData(phone);
                    }
                }
            }
            
        
    }
И массив с которого выводится символ:

Здравствуйте, у меня возник вопрос - как вывести 24 битный шрифт на дисплей?
Двухмерный массив символов 16 битного шрифта
Что есть 24-битный шрифт ? То, что ты назвал 16-битным это шрифт 8x16. А 24-битный это что ? 12x24 или 24x24 ? Сколько на сколько шрифт тебе нужен ?

И в массиве твоего 16-битного шрифта самый левый байт в каждой строчке 00 и самый правый в каждой строчке 00. Зачем эти незначащие нули хранить, они смысла не несут, а место занимают ? Удали их и в цикле принудительно поставь при индексе h=0 ноль, при индексе h=0xF ноль и обращение к массиву по индексу [h-1].

И в чем принципиальная разница между одномерным массивом и двумерным ? Скобочки в одномерном массиве расставь и он станет двумерным, скобочки убери и обратно одномерным. Одно легко переделывается в другое прямо в исходнике.
