STM32 LCD中英文字符顯示學習筆記

本文轉載自查看原文 2019-05-06 22:57 804 STM32學習筆記

本實驗基於STM32 LCD英文字符顯示學習筆記、STM32 SPI Flash學習筆記這兩個程序編寫

開發板：野火指南者（STM32F103VE）

STM32庫版本：STM32F10x_StdPeriph_Lib_V3.5.0

IDE:KEIL5（代碼編寫很不方便，只在編譯的時候用到）

代碼編寫工具：Source Insight 4.0（跟讀代碼、編寫代碼的最佳工具，會對本實驗項目中文顯示有點問題，main.c中會提到）

硬件原理圖：

1. 新建user_spi_flash.h、user_spi_flash.c、user_fsmc_lcd.h、user_fsmc_lcd.c、main.c 5個文件，並從

STM32官方庫的例子中將stm32f10x_it.c、stm32f10x_it.h、stm32f10x_conf.h拷貝到自己的工程目錄下。

2. 在user_spi_flash.h中添加如下代碼

總結：

1. 編寫要顯示中文時，最好不要使用SourceInsight來寫，不然會因為保存的時候因為編碼不一樣，導致KEIL5編譯程序后，LCD顯示的字符為亂碼，如果實在需要用SourceInsigt來編寫，通過先建立KEIL5工程，將各文件加載好后，再使用SourceInsight來編寫，可能會避免這個問題

2. 當程序出現問題不能正常工作時，通過OK代碼（野火的代碼）來一步一步替換查找自己的代碼異常的地方，可以快速定位問題。
