DSPS extended sleep current consumption
I'm using DSPS. If I measure the current of BLE IC during sleep period(stop advertising), the current is about 150uA.
This is normal current of DSPS sleep current or may I do something wrong about sleep mode?
SLG46826重置
Forums:
Hi,
For SLG46826, I do realize we may reset the chip via Vdd and I2C softtware reset, but is there any way to use one pin as reset input and then reset the chip?
Thank you!
Best regards,
Joe
Vias for WLCSP34
Hi Dialog,
I need more then 6 IO pins for my application with the WLCSP footprint. Since micro vias, i.e. 0.1mm Φ, are expensive here, is it possible to use normal vias （0.2 mmΦ）in the WLCSP empty area as shown in this figure?
DA9063 won't reset after watchdog timeout
Hello,
I am currently developing BSP for a custom iMX6-based board.
I am trying to enable the DA9063 Watchdog feature.
The timeout works OK, but when it's meant to reset, the iMX just stops. All PMIC voltages seem to remain the same, and the iMX won't reboot until I manually write 1 in the SHUTDOWN bit (bit 1) of register CONTROL_F (0x13).
Also, the exact same behaviour is reproducible by writing 1 in SHUTDOWN bit while the iMX is alive. Then I have to re-write 1 in the SHUTDOWN bit, otherwise the iMX won't reset.
I2C read / write
Hi all,
I am working on I2C interface code. I have referred i2c_eeprom driver code. few the code snippet i am not understanding means exact working of code.
If any one help to understand then it will be very helpful for me to interface my sensor.
slave device using is IQS333 touch sensor. where i am not able to communicate properly.
da14580低功耗IO保持问题
Hi Dialog,
我们在做一款监护手环类的产品,需要14580做蓝牙主端,同时控制GSM通信模块的电源
软件上我们设置了app_default_sleep_mode = ARCH_EXT_SLEEP_ON,有时需要拉高 GSM的电源控制IO 并保持,但是测试发现IO口的电平在进入低功耗之后变低电平了
于是我在periph_init函数里面添加了恢复IO状态的代码,但是仍旧有10微秒的IO下降沿,这样我的受控的GSM系统会短暂断电导致异常
想请问下有没有什么办法能在低功耗状态下保持住IO的状态?
还是我这种场景就不能使用sleep模式了?
谢谢
Best Wishes
Walt
自定义服务的属性读写问题
您好，很久没来论坛了。从14年到现在一直用DA14580在做产品。之前用的SDK3所以一直都没什么问题。
现在公司的新产品打算用SDK5，我参考“Dialog SDK 5.0.3培训材料2自定义协议“文件并使用了SDK5.0.4下的ble_app_all_in_one这个项目来进行试验。
添加新的特征值之后，运行起来的设备能被手机上的工具软件扫描并且能和手机上的工具软件进行连接。
我发现当我用手机上的蓝牙工具对自定义的特征进行写入数据时，并没有回调对应的gattc_write_cmd_ind_handler（...）函数，我记得在SDK3上是会回调
gattc_write_cmd_ind_handler（...）的。请问ble_app_all_in_one这个项目能实现对特征值进行操作吗？写入数据是会调用哪个回调函数？
about GLOBAL_INT_STOP
Hi, Dialog,
about Initialize RW
Hi, Dialog,
Now I'm running the ble_app_all_in_one project in DA1458x_SDK sample and I found a problem.
A function rwip_init(error); is written in system_init() located in arch_system.c.
During debug, it faulted at the rwip_init(error);.
当我看到entity of the function, it exists under the condition #if (!BLE_HOST_PRESENT).
So I think before at the rwip_init(error) calling #if (!BLE_HOST_PRESENT) is also needed.
Actually after inserted #if (!BLE_HOST_PRESENT) before at the rwip_init(error), debug proceeded.
Am I right?
add UART into DA1458x_SDK project
Hi Dialog,
Now I'm struggling to add UART2 communication into ble_app_all_in_one project in DA1458x_SDK sample project.
UART2 communication with uart2_async project in same DA1458x_SDK sample project works fine.
But by adding the uart2_async function into the ble_app_all_in_one project, UART2 communication doesn't work normally.
As UART2 functions, I just only same uart2_async functions.
Following abnormal phenomena occur.
Just run by debugger, character beta in Greek appears in console.
