Hi, TouchGFX community
I'm trying to get TouchGFX working on a STM32F401RE device with a 200x200 screen.
I've created a simple project with one screen and text as 1bit color depth (Idither_algorithm := 2, opaque_image_format := BW, non_opaque_image_format := BW on app.mk) and I use these configuration on BoardConfiguration.cpp:
uint8_t frameBuffer[5000]; //200 * 200 / 8
uint32_t frameBuf0 = (uint32_t)& frameBuffer[0];
namespace touchgfx
{
NoDMA dma;
NoTouchController tc;
LCD1bpp display;
void touchgfx_init()
{
HAL& hal = touchgfx_generic_init<MyFakeHAL>(dma, display, tc, 200, 200, 0, 0);
hal.setFrameBufferStartAddress((uint8_t*)frameBuf0, 1, false, false);
hal.registerTaskDelayFunction(&OSWrappers::taskDelay);
// Enable strategy.
hal.setFrameRefreshStrategy(HAL::REFRESH_STRATEGY_OPTIM_SINGLE_BUFFER_TFT_CTRL);
hal.setFrameRateCompensation(false);
hal.lockDMAToFrontPorch(false);
}
I think that framebuffer big is enough for a 1 bit per pixel ( 200 * 200 / 8 bytes). Everything compiles OK but at debug system crashes always when trying to draw at touchgfx::LCD1bpp::drawGlyph()
I've seen other examples and they always use uint16 [width *height] arrays for creating the frame buffer, but this should only be needed in case of 16BPP. Its also needed for working with 1BPP? If not, what's happening?
Thanks,
