Hey,
I want to use the SSD1306 display with the STM32F103 controller.
In the "gfxInit();" the uGFX logo is shown, which implies that the I2C works (the write_cmd and write_data).
But when i want to display some text, notting happens.
I write:
" font1 = gdispOpenFont("DejaVuSans12");
font2 = gdispOpenFont("DejaVuSans20");
// Show some stuff on the display
gdispDrawString(5, 5, "Hello uGFX!", font2, Black);
gdispDrawString(5, 35, "Temp. 1: 24.1", font1, Black);
gdispDrawString(5, 50, "Temp. 2: 28.3", font1, Black);"
But the write_cmd and write_data are never called (except in the init funct) and the controller is never sending data.
