TouchGFX BW (1 Bit) Mode Load Image Fails, BUG

by ADMIN 47 views

Introduction

TouchGFX is a popular graphical user interface (GUI) framework for microcontrollers, particularly those from STMicroelectronics. It provides a powerful and flexible way to create user interfaces for embedded systems. However, like any complex software, it is not immune to bugs and issues. In this article, we will discuss a specific problem that some users have encountered when working with TouchGFX in 1-bit mode, specifically with custom SPI displays.

Symptoms

The issue at hand is that any image widget added to the GUI appears black, regardless of the configuration settings. This is a problem because it prevents users from displaying images on their custom SPI displays, which can be a critical feature for many applications.

Background

To understand the issue, it's essential to have a basic understanding of how TouchGFX works in 1-bit mode. In this mode, the framework uses a single bit to represent each pixel, which can be either 0 or 1. This is in contrast to the more common 24-bit or 32-bit modes, where each pixel is represented by multiple bits.

When working with custom SPI displays, users need to configure the display settings, such as the pixel clock, data transfer rate, and display resolution. These settings are critical to ensure that the display works correctly with the TouchGFX framework.

Causes of the Issue

After investigating the issue, it appears that the problem is related to the way TouchGFX handles image loading in 1-bit mode. Specifically, the framework is not correctly interpreting the image data, which results in the image appearing black.

There are several possible causes for this issue:

  • Incorrect image data format: The image data may be in the wrong format, which can cause TouchGFX to misinterpret the data.
  • Display settings not correctly configured: The display settings may not be correctly configured, which can cause the display to malfunction.
  • TouchGFX framework bug: There may be a bug in the TouchGFX framework that is causing the issue.

Troubleshooting Steps

To troubleshoot this issue, users can try the following steps:

  • Verify image data format: Ensure that the image data is in the correct format, which is typically 1-bit per pixel.
  • Check display settings: Verify that the display settings are correctly configured, including the pixel clock, data transfer rate, and display resolution.
  • Update TouchGFX framework: Ensure that the TouchGFX framework is up-to-date, as newer versions may have fixed the issue.
  • Use a different image widget: Try using a different image widget to see if the issue is specific to the current widget.

Workarounds

If the issue cannot be resolved by troubleshooting, there are several workarounds that users can try:

  • Use a different display: If possible, try using a different display that is not custom SPI.
  • Use a different image format: Try using a different image format, such as 24-bit or 32-bit.
  • Use a different image widget: Try using a different image widget to see if the issue is specific to the current widget.

Conclusion

In conclusion, the issue of TouchGFX BW (1 bit) mode load image fails is a complex problem that requires careful troubleshooting and analysis. By understanding the possible causes of the issue and trying the troubleshooting steps, users can resolve the problem and display images on their custom SPI displays.
