最近自己组了一个MMDVM盒子，顺便研究了一下串口屏固件开发，写了一个固件，目前在DMR模式下测试良好，但因为没有其他制式设备，所以YSF等其他模式没有写，如果哪位可以提供YSF模式下的串口原始传输数据的话后续可以添加进去。屏幕固件基于TJC8048X370_011开发，测试硬件为树莓派4+双工热点板，WPSD系统，Nextion驱动。DMR模式支持双时隙，可显示呼号、姓名、组呼号，所在国家/地区（包括根据国内呼号判断所在省份），以及最后6个呼叫。如果有TJC X系列800*480分辨率串口屏的可以联系我获取相应固件测试，T系列和K系列因为部分控件属性与X系列不同可能需要一些额外调整。 [upl-image-preview url=https://storage.hamcq.cn/2024-05-29/1716987204-756409-tjc8048x370-wpsd.png] [upl-image-preview url=https://storage.hamcq.cn/2024-05-29/1716987205-589847-tjc8048x370-wpsd2.jpg] [upl-image-preview url=https://storage.hamcq.cn/2024-05-29/1716987544-210115-img-0663.jpg]

20240721更新了3.5寸屏幕固件，修正WPSD系统12小时制转换24小时制的BUG，并额外增加了一点点小改进。此版功能基本成型，后续不会花费太多精力更新版本。故本版本开始提供HMI文件，各位HAM可以自己修改适配屏幕型号、显示方向等。免费使用，但修改请保留原作者信息。如有发现BUG或优化代码请也请抄送原作者。链接: https://pan.baidu.com/s/19FrWKRvhTgzIQMzrHmCHLQ 提取码: 7ANY

左上角呼号的风格有点眼熟

@"BD4MCG"#p19065 左上角呼号是会根据MMDVM盒子的呼号自动更新的。至于配色风格……不要问，问就是本人的恶趣味😏

@"BH7FBP"#p19052 算了吧，光搞清楚串口屏控件和MMDVM通信指令就用花了一个多星期，还只搞定了一个DMR……

这个固件看着不错啊大佬知道哪里可以下载外壳的3D打印文件或者购买成品外壳吗？多谢🙏

@"BI7ANY"#p19076 串口屏的指令能发到mmdvm host处理了？github那个open的bug 开发一只没close

@"DF4_9460"#p20613 外壳某宝搜就有

@"BI1RRE"#p20618 NextionDriver的说明里是提到可以侦听串口返回的指令，但我反复测试后，最多也就切换下页面，调整下屏幕亮度这种，其他诸如关机、重启、更新系统等功能通过串口指令都无法实现。

I have created an MMDVM serial port firmware. Please test it.

BD4TZY

I found a bug: when a new call sign, such as USER BD4TZY, is entered in slot 2, it only displays TZY. Changing the starting position to 5 resolves this issue.

BI7ANY

BD4TZY Huh? Shouldn't the 't13' field only return the call sign, but it seems to have changed…?
Okay, let's just use the 't0' field to determine that instead. And while we're at it, let's also update the other fields as well.

BI7ANY

It's been updated again!
1. In DMR mode, the national flag code is changed to be identified by the call sign, just like in other modes. However, if only the digital ID is available, it cannot be determined.
2. In DMR mode, the call sign is now retrieved from the "t0" field, and it automatically determines whether it is a numeric ID. Now, the call sign or 7-digit numeric ID should be displayed correctly.
3、A clock has been added to the calling page.
4. Finally, adjust the contents of the call list so that each entry displays the call time, mode, call number, country, and group call number (the 7-inch screen also displays the call mode).
The latest version is 20241001, and it has been synchronized to update.Cloud storageAndGitcode。

Respecting the seniors

Hello teacher, I encountered a situation and would like to ask for your advice. When I put "t0" on the mmdvm page, it normally displays the call sign/ID. However, sometimes it jumps to content like "RIC: XXX" (e.g., RIC: 208, RIC: 224, RIC: 226), and the subsequent numbers may or may not change, but there is always "RIC:" before them. I'm not sure what the problem is.

BI7ANY

aline The "t0" field displays different content on different pages, but I haven't encountered this situation before.

BI7ANY

Fixed a few minor bugs, and also updated the previous English version. The latest version is 20241008. You can download it from BaiduDisk.

I just restarted the box, but it suddenly can't start the service. I suspect that either the system card or the hotspot board is malfunctioning. It probably won't be updated in the short term, so I will focus on getting the Black Monkey fully functional first.🤪

BH2VLF

Original Poster: I would like to change the patterns in the list to "lost" or "misread rate", is that possible?

BH2VLF

BH2VLF I think, since you have already grouped the patterns, there's no need for me to display them individually.

BI7ANY

BH2VLF According to the comments in the NextionDriver code, the system sends field strength and bit error rate information over the serial port. However, when I read the serial data from a physical device, both values are empty. This means that the serial monitor does not display field strength or bit error rate, and packet loss rate is also unavailable.
Regarding the issue with the time, it's handled through RTC code. If the screen doesn't have an RTC clock or if the RTC time isn't calibrated, errors will occur.

BH2VLF

I've found a problem: The date display is incorrect.

BH2VLF 大佬，你这个壳子看着不错，哪里可以定制哈？谢谢

BH2WBA

I have a 3.5-inch screen and WPSD system. After updating recently, the time display is not working correctly. Has anyone else experienced this? How can I fix it?

BH2XLC

Hi, OP. How can I make every page display at maximum brightness? Because I'm using it with a power adapter, and the TJC screen has a very narrow viewing angle, which makes the low brightness not clear.

BG7PUW

BH2XLC

BI7ANY

BH2XLC Currently, the system sends a "dim=50" command every time it receives a call, which sets the screen's current brightness to 50%. Even if the default brightness (dims) is set to 100, the screen will still adjust its brightness after receiving the "dim=50" command. Therefore, this issue currently has no solution.

BH2XLC

BG7PUW After adjusting, it was set to 100 brightness. Only the startup page appeared at full brightness, while the call and standby pages remained dim.

BH2XLC

BI7ANY I couldn't find that command anywhere.😂

BI7ANY

BH2XLC 意思是不管我的屏幕固件怎么改，每次收到呼叫系统都会自动让屏幕亮度变为50，除非你能接受屏幕亮度在50和100之间来回闪烁。
推测应该跟nextion driver有关。

BG7PUW

BH2XLC 高级设置Advanced》 MMDVMHost》RemoveDim的0改成1，保存，重启，亮度就不会变了
