我通过在Smart Snippets Power Profiler中观察当前波形看到唤醒。我试图在da1458x_config_advanced.h中更改CFG_MAX_SLEEP_DURATION_EXTERNAL_WAKEUP_MS的值,但没有看到自动唤醒频率的变化。
当我消除app_easy_timer唤醒时,设备不会自己唤醒。只有设置了计时器,我才会看到10秒起床。 Is there any way to prevent periodic wakeup?
Hello!
我想用DA14580构建一个基本电路(最小功能)。我的目标是只有天线,电源,编程接口
和振荡器在板上本身,并连接所有其他引脚插头带,以便我可以添加其他电路的布局
(例如。ADC的不同输入,试图用GPIO管脚来控制一些东西)。
我阅读了启动指南,有几个问题:
-根据指南,我可以通过SWDIO和SWCLK引脚使用SWD接口编程DA14580
或使用RS232电平转换器使用P0_4和P0_5引脚。现在,我没有硬件限制,
我应该使用哪个接口?使用另一个接口来编写DA14580有什么缺点吗?
-如果我在降压模式下工作,32kHz的外部睡眠时钟是必要的吗?或者我可以使用内部振荡器没有任何缺点吗?
当决定睡眠时钟使用哪个振荡器时应该考虑哪些因素?
-我想使用一些GPIO引脚进行ADC测量,我必须把电阻放在引脚前面吗?
引脚是否受到更高电压级别的保护?
My sensor output will have a output coltage between 0V and 3V and an output current of around 10mA.
-Is it possible to solder the DA14580 onto the PCB using a reflow oven and a template for the solder paste?
-There is an application note on how to design printed antennas. Can I just use a ready made design for my layout
considering the limitations mentioned in the application note?
-My simple circuit is included and I want to have all floating pins connected to plugs to use with other circuits.
Can someone please confirm if the circuit will work or what I have to correct to make it work?
I know those are a lot of questions but I want to make sure the circuit is correct before I make the PCB
since I do not have the ressources to make multiple different PCBs of the minimalistic circuit I want to use
and want to add additional functionality later using bread boards or something cheaper than a PCB.
Kind Regards,
Reichel Robert
方法1:
我们在SPI flash刻录FW。如果可以的话,我们是否可以通过修改hex文件的BD地址来修改BD地址?
如果我们能做到这一点,请帮助我们知道如何做。
方法2:
We burn FW in SPI flash。然后把BD地址从OTP改过来。
但是我们只是想更改BD地址,在OTP中不使用其他设置。我们该怎么办呢?
你能在SmartSniooets工具箱v4.7.3.1690中提供刻录的OTP文件和命令行方法吗? (Jtag port)
We will directly burn that OTP file from Dialog.
(hope to provide the method to us step by step.)
If you have other better method to change BD address when FW is burned to SPI flash, please help to tell us.
Thanks.
