DA1468x

AD14680 PXP工程总是出现死机问题。

技术服务你好!
我现在遇到一个比较棘手的问题,我在PXP工程新建了一个任务。任务里面同时使用了I2C和SPI端口,并且每隔一段时间就读取两个端口设备。但是这个新建的任务总会遇到不运行的时候,现在我不知道从哪里下手解决。谢谢!
void User_APP(void)
{
static unsigned char TX[10];
static unsigned char RX[16];
i2c_device I2C_dev;
spi_device SPI_dev;
port_init();
demo_i2c_init();
SPI1_init();
setup_breath(0, 255, 255, 255);
I2C_dev = ad_i2c_open(M41T62);
TX[0]=0x04;
TX[1]=0x92;
ad_i2c_write(I2C_dev, TX, 2);
TX[0]=0x0A;
TX[1]=0x40;
ad_i2c_write(I2C_dev, TX, 2);

Hi Everyone:

I have a question regarding programming on the DA1468x development kit. When I run my code, I get the following on my console for smartsnippets:

Typical current consumption of DA14681?

We used ble_adv project on homemade minimal system board (SDK v1.0.6.968) to investigate low energy function.
we have settings as below:
pm_set_sleep_mode(pm_mode_extended_sleep);
advertisement interval is default 687.5ms.
During the test, we have two readings which are significant with official documents:
1, active current is 2ma from start to 8s.
2, current drop down to 600 ua after 8s later.

DA14681低功耗电流测试和官方资料显示误差的问题请教

请问下我使用DA14681的sdk:v1.0.6.968的ble_adv工程, 配置如下:
pm_set_sleep_mode(pm_mode_extended_sleep);
广播间隔是代码默认 687.5ms。
现象:
1.da14681启动到8s的时间电流检测显示2ma左右。
2.8s之后进入extended sleep后电流显示600ua左右。
请问下:
现象1的工作电流2ma正常么?
现象2的电流我在官方文档"AN-B-037 DA1468x Power measurements_v1.3.pdf"
中显示在广播间隔1000ms时平均电流在20.3713ua,那我实际测试是600ua左右,
请问下问题在哪里?

p.s 硬件条件是DA14681最小系统,没有其他芯片在工作。

DA14681降低主频使用的问题请教

请问下我使用DA14681的sdk:v1.0.6.968的pxp工程,系统默认时钟配置如下:

cm_sys_clk_init(sysclk_XTAL16M);
cm_apb_set_clock_divider(apb_div1);
cm_ahb_set_clock_divider(ahb_div1);
cm_lp_clk_init();
... ...
/* Set system clock */
cm_sys_clk_set(sysclk_XTAL16M);

DA14681 pro board works well with debugger, but halted when run alone

Hi, Dialog,
I build a app based on px reporter, add a timer to read data from I2C bus through adapter when connected to a central device.
the most strange thing was, it worked well when in jlink jtag mode, but halted after connected and send several packets of data when work alone. I used attach function and found it ended in the loop of hw_hard_fault.c.
What would be the reason?
Thanks a lot.
Regards.
Duan
