Hello everyone,
I am working on implementing display output using the STM32H747I-DISCO board. After designing the display in TouchGFX and generating the project code, I encounter a serious issue: when I modify the .ioc file (for example, enabling TIM or CAN), the onboard display that was working fine before suddenly shows heavy noise.
To resolve this, I have carefully checked the clock configuration and excluded any pins that might affect the display during code generation, but unfortunately, I have not been able to solve the problem.
If anyone has experienced a similar issue or knows a solution, I would greatly appreciate your advice.
Thank you for taking the time to read this.
For the chinese helpers…
大家好,
我正在使用 STM32H747I-DISCO 开发板实现显示输出功能。在 TouchGFX 中完成显示设计并生成工程代码后,出现了一个严重问题:当我修改 .ioc 文件(例如启用 TIM 或 CAN)时,原本正常工作的板载显示屏会出现严重的噪点。
为了解决这个问题,我已经仔细检查了时钟配置,并且在代码生成时避免使用可能影响显示的引脚,但最终仍然没有解决。
如果有朋友遇到过类似的问题,或者知道解决办法,非常希望能得到您的建议。
感谢您抽时间阅读。
