Unable to display Text on the LCD (Controller)

asked Dec 21, 2018 in System Integration by Chaitra

Working on Rx65n controller dev board. We have developed a UI with some text and background images using embedded wizard studio 9.10 pro. Using RGB565 package.

The baground images are properly displaying on the LCD but the Text is not showing up. If we run in EW then the text is visble but not visible on the frame buffer.

Extracted bramebuffer from the target board is attached in hex and bin format. We have reconstructed the image using the framebuffer extarcted data though http://rawpixels.net/ , here the text is not visible.

if the text does not appear within the framebuffer, it is very likely that it is not drawn: For text drawing it is necessary that it is processed first (e.g. alignment and word wrapping) - then it will be drawn. Does your main loop contain the function EwProcessSignals()? If this is missing, the drawing of text cannot be done.

Furthermore: Do you have established a serial connection between you target and a terminal window on the PC in order to receive debug and error messages? Please post the output.

Thank you and best regards,
