Bigger font ssd1351, Arduino M0 Pro #50

Closed FrogManBird closed 5 years ago

FrogManBird commented 5 years ago

Please provide the following information:

library version 9d74c90

LCD display type 1.5 inch 128x128 ssd1351

Steps to reproduce the issue N/A

Expected behavior N/A

Actual behavior N/A

The good news is that I have this up and running on an Arduino M0 Pro (which I'm sad that they've retired because it's great). The bad news is that I can't figure out how to get bigger font than the 6X8 using: ssd1306_setFixedFont(ssd1306xled_font6x8); ssd1306_printFixed8(0, 16, "Test String", STYLE_NORMAL);

I see routines like ssd1306_printFixedN in the code, but I can't seem to get them to work on this system. It's probably operator-error on my part. Can you show me the light on this?

Hello,

Could you please send me compilation command for the files of ssd1306 library (you can get it if enable verbose mode in Arduino IDE)? Does direct_draw/draw_text work well for you? If not, can you take a picture of lcd content?

Hi, FrogManBird is my old account. Anyway, I got it working now. You guys did a really outstanding job on this.

direct_draw/draw_text did indeed work fine. Then I realized a few things, mainly that this statement was creating a mess: ssd1306_setMode( LCD_MODE_NORMAL ); //this caused screen mess problem, using ssd1351 no better

Long story short, here's a version of your draw_text program that I tweaked to work on my system, this one showing how to use colors as well:

include "ssd1306.h"

void setup() { //works with Arduino M0 Pro running a 1.5 inch 128x128 ssd1351 display //MOSI and SCK connected to ICSP header. Other 3 SPI signals connected to digital pins below ssd1351_128x128_spi_init(3, 4, 5); //RST, CS, DC ssd1306_setFixedFont(ssd1306xled_font6x8); ssd1306_clearScreen(); ssd1306_printFixed (0, 8, "Line 1. Normal text", STYLE_NORMAL); ssd1306_setColor(RGB_COLOR16(255,0,0)); //must use COLOR16 witb ssd1351 ssd1306_printFixed (0, 16, "Line 2. Bold text", STYLE_BOLD); ssd1306_setColor(RGB_COLOR16(255,255,0)); ssd1306_printFixed (0, 24, "Line 3. Italic text", STYLE_ITALIC); ssd1306_setColor(RGB_COLOR16(255,0,249)); ssd1306_printFixedN (0, 40, "DoubleSize", STYLE_NORMAL, FONT_SIZE_2X); ssd1306_setColor(RGB_COLOR16(252,147,3)); ssd1306_printFixedN (0, 68, "4", STYLE_NORMAL, FONT_SIZE_4X); ssd1306_printFixedN (0, 96, "X", STYLE_NORMAL, FONT_SIZE_4X); ssd1306_setColor(RGB_COLOR16(16,239,33)); ssd1306_printFixedN (30, 72, "8X", STYLE_NORMAL, FONT_SIZE_8X);
}

void loop() { }

Thank you.

ssd1306 library has 2 sets of functions: with 8 suffix (like ssd1306_printFixed8()) and without 8 suffix (like ssd1306_printFixed()). Functions without the suffix work in ssd1306 compatible mode, that is: GDRAM addressing mechanism is the same as for ssd1306 controller. Such addressing has some limitations. Function with the suffix 8 work in native mode for selected display. By default, for any supported display the ssd1306 library works in ssd1306 compatible mode.

Unfortunately, ssd1306_printFixedN8() is not yet implemented. But you can switch between modes using ssd1306_setMode() as you already know.
