与LCD模块通信的STM32有什么问题 [英] What's wrong with STM32 which communicating with LCD module

问题描述

我目前在HY28B液晶显示模块上显示有问题。我在16位模式下配置我的LCD模块，在正确的地方焊接正确的短路我正在使用STM32 [url] = http：// www.kynix.com/Detail/1223233/STM32F103C8T6%20ARTC.html[url];发现板STM32发现板驱动LCD模块。我移植了卖家给出的源代码，并尝试了在互联网上找到的许多初始化序列。我当然可以读取与ILI9235 LCD驱动器相对应的9325的部件号寄存器，但我不能再进一步了。这是我的代码，我的唯一目的是用一种颜色填充显示器，以便建立正确的方式来与它进行交流，不幸的是显示器仍然是白色的。您将在源代码中找到我的引脚分配，除了我的复位和背光引脚与3V3相连。





我尝试了什么：



我不知道问题出在哪里。

解决方案

< blockquote>我首先用万用表和示波器检查电子，也可以用逻辑分析仪。

你需要确保电子配置没问题。

确保LCD接收的内容。

我担心远程无法提供太多帮助。

I'm currently in trouble with displaying something on the HY28B LCD module.I configured my LCD module in 16bits mode by soldering the right short at the right place and I'm using an STM32[url]=http://www.kynix.com/Detail/1223233/STM32F103C8T6%20ARTC.html[url];discovery board STM32 discovery board to drive the LCD module. I ported the source code given by the seller and tried many init sequences found on the internet. I currrently can read the part number register wich is 9325corresponding to the ILI9235 LCD driver but I can't go further. Here is my code, my only aim is to fill the display with one color to establish the right way to comminicate with it unfortunatly the display remains white. You will find my pin assignation in the source code except for my reset and backlight pin wich are tied to 3V3.


What I have tried:

I don't konw where the problem is.

解决方案

I would first check the electronic with a multimeter and a scope, may be also with a logic analyzer.
You need to make sure sure the electronic configuration is OK.
Make sure what the LCD receive.
I fear not much help is possible remotely.
