你好。 我订购了steval-ihm022v1板。当我熟悉电路板时，我将提供的fw项目（具有较小的适应性）和lcd项目闪存到uC上并且它工作得非常好。但大约一个小时后，显示屏停止显示任何内容。它只是空白。我试过闪烁lcd和fw项目的各种组合，但显示屏保持空白。 是否可以获取原始闪存映像以验证问题是否与HW无关？可能是一个lcd测试fw可用于验证显示器？ BR，伯恩哈德以上来自于谷歌翻译以下为原文 Hi. I ordered the steval-ihm022v1 board. As I was familiarizing myself with the board I flashed the provided fw project (with small adaptions) and the lcd project onto the uC and it worked quite fine. But after about an hour the display stopped showing anything. It's just blank. I tried flashing various combinations of lcd and fw projects but the display stays blank. Is it possible to get the original flash image to verify that the problem is not HW related? Is maybe a lcd test fw available to verify the display? br, bernhard

你好ST社区，对不起，也许我应该在这里发布我的问题。现在我正在研究wifi模块X-细胞核 - IDW01M1，我发现了一些问题。硬件：细胞核 - F401RE，X-细胞核 - IDW01M1软件 ：STM32CubeExpansion_WIFI1_V3.0.1IDE：iar arm 7.70.1从示例项目中我发现两个类型一个是SPWF01另一个是SPWF04，我发现示例二进制是SPW04。我将配置更改为SPWF01，但它仍然无效。从Tera术语我发现了打印消息，但是当我输入'AT + S.STS'时，没有输出。从这个例子来看，它总是在wifi init上运行。 文件 wifi_module.c第294行并且不能用完这个功能。它似乎在等待状态。我只在wifi_conf.h中改变了一件事旧的是#define SPWF04，我改为 #define SPWF01 / ********* / while（IO_status_flag.WiFi_WIND_State！= WiFiHWStarted） { __NOP（）; //没事做 }//总是在这个功能中/ *************** / 有没有人可以告诉我有什么问题？非常感谢你。以上来自于谷歌翻译以下为原文 Hello ST community,sorry,maybe I should post my problem here.Now I am working on the wifi module X-NUCLEO-IDW01M1,I found some problem.Hardware:NUCLEO-F401RE,X-NUCLEO-IDW01M1Software :STM32CubeExpansion_WIFI1_V3.0.1IDE: iar arm 7.70.1From the example projectI found two types one is SPWF01 another is SPWF04, I found the example Binary is the SPW04.I change the config to SPWF01,but it still not work.From the Tera term I found the print message,but when I input 'AT+S.STS',nothing output.From this example it will always run at the wifi init. file wifi_module.c line 294 and can not run out this function.It seems to wait for the state.I only changed one thing in wifi_conf.hthe old one is #define SPWF04,I change to #define SPWF01 /**********************************/while(IO_status_flag.WiFi_WIND_State != WiFiHWStarted) {__NOP(); //nothing to do }//always in this function/*******************************/ Is there anyone can tell me what is wrong ? Thank you very much.

我想知道数组的大小与RAM的可用性有关。如果我在主.c文件的任何函数之外分配一个数组，那么看起来我不能像我喜欢的那样大，所以我必须在512 UIT32上停止，否则我会在内存中产生内存不足的错误。但是如果我把数组移到函数中实际使用它的离子，我可以把它做成1024个没有问题。那么我怎么才能知道我能在多大程度上做到这一点呢？我的设备是PIC24FJ256GB206，具有96 KB的RAM，这意味着完整的第一页0x000—0x7FFF可用（除了第一个2K寄存器重叠的地方）。 以上来自于百度翻译 以下为原文 I am wondering about the size of arrays concerning RAM availability.If I assign an array outside any function in the main.c file then it seems like I cannot make it as big as I like, I had to stop at 512 UINT32 otherwise I got a memory shortage error on build.But if I move that array into the function that actually uses it, then I could make it 1024 without problems.So how can I find out how big I can make it at the most?My device is PIC24FJ256GB206 with 96 kB of RAM, which means the the full first page 0x000-0x7FFF is available (except the first 2K where registers overlap.How much of this is available for local function variables?
