Limitations to using pin 1_2 and 1_3
Hi
I came across a custom board design around the Da14580 which has something peculiar in it's schematic. It states that "P1_2 and P1_3 cannot be toggled when 16 MHz XTAL is" .(the last word is cut off).
Is there any restriction on using pin 1_2 and 1_3 ? Is there any special dependency on the XTAL or some other peripheral ?
I tried looking for this in the datasheet but didn't find anything
Can I safely use it in my design for I2C ?
Thanks,

1，硬件板子应该是没问题。因为其他工程范例是可以正常运行。Jlink SW模式也是可以在keil中被识别到，没有问题。
2，根本没有进去debug，弹出错误如下，所以应该不是睡眠的问题。
3，点击“debug”后，错误提示“verification of application image failed.Target contents do not match!flash download not performed?”
SUOTA multi part Binary tool - Bug - debug build of mk
The mkimage.exe application in the bin folder was compiled as a debug build. This requires the user to have Visual Studio 2010 installed, or to illegaly obtain a copy of the debug CRT DLL from somewhere else on the internet.
This can be observed by running the application on a system that does not have Visual Studio 2010 installed. You will get a dialog box like this:
Scatterfile warning
Hi
I am using the barebone project and I wanted to make some changes to arch_main , so I made a copy of it in my project, removed the SDK file from the Keil project structure and added mine.
I get the following warning message when creating the build.
Is this important ? How can I fix it ? The code seems to work when in debug mode
.\..\..\..\..\..\sdk\common_project_files\scatterfiles\scatterfile_common.sct(490): warning: L6314W: No section matches pattern arch_main.o(BLE_exchange_memory).
RSSI on Central without connection conversion
Hi,
In continuation of my previous question, the RSSI value return through adv_report struct will need to be converted to get value in dBm using following formula. Is my understanding right?
i.e.
LRES = param->rssi
and
RSSi (dBm) = (0.474 * LRES) – 112
Thanks.
请问如果要实现手机音乐上曲/下曲/播放，显示歌曲名字
请问如果要实现手机音乐上曲/下曲/播放，显示歌曲名字。无须手机端安装APP。
请问可以用sdk里哪个范例去实现类似功能？
与手机通讯的范例
第一次开发蓝牙设备，在阅读了相关文档之后依然是一头雾水，可否提供一个与手机通讯的范例？连接之后发送一个字节到手机上就可以。谢谢！开发板为14580-Basic
PS：对零基础开发的人员，可否提供一些建议？
KBD_3.10.6 能运行。但扫描不到
我用keil 仿真运行 KBD 3.10.6. 能运行起来，但是手机没有扫描到广播。
请问有什么地方需要注意，或者修改的吗？
External PAN1740 FIrmware upload
- Can you use a Basic dev kit to program a external pan1740 beacon unit?
- I hooked up as attached and the could not detect the device in debug for port SW or JTAG to program. tried on two modules
- Pls have a look at the attached for the pin connection
- Do I have to acquire another different kit
- SPI flash was not connected yet, I wanted to port the code to the sram of the chip and jtag interface I think is sufficient
-Whats wrong here
