DA14583 IoT Sensor Gyroscope Sleep Problem
Dear All,
I2C interface source code DA14583 IoT Development Kit
Hi MT_Dialog,
I've downloaded SDKv5.160.1.19 wrbl for "DA14583 IoT Sensor Development Kit".
As I see from Sensor Board Schematic and from some code strings commented in code this Sensor is ready to work using both SPI or I2C interfaces to connect Sensors<=>DA14583.
But it looks like I2C part of source code is missed in this SDK.
Now I need to add 2 more sensors to this board. Only one way I can do this is to use I2C interface (Sensor PCB hasn't reserved CS pins with pads available to connect additional sensors).
DA14583 IoT sensor specifications
I am interested in purchasing the DA14583 IoT sensor, and I would like to ask some questions regarding the product:
1. What is the maximum sampling rate for the Accelerometer, Gyroscope and magnetometer?
2. Can we access the raw sensor data?
3. Can we use the sensor data on another application?
4. Is there any available tutorials for developing applications?
Power Consumption Extended Sleep Mode
Hi Dialog,
We are using the DA14583 in a smart button and currently have a custom power management circuit that shuts down the DA14583 completely.
The down side is that we are unable to "catch" fast clicks (input signal duration 50 - 200ms). We guess this is due to the boot sequence of the DA14583.
We have also considered using the extended sleep mode but are concerned about power consumption.
Connection Interval data transfer slow
亲爱的Dialog
I have changed the connection interval on a DA14583 dynamically using the code below
struct gapc_param_update_cmd * req = KE_MSG_ALLOC(GAPC_PARAM_UPDATE_CMD, TASK_GAPC, TASK_APP, gapc_param_update_cmd);
RX_BUFFER_ITEM_COUNT size increase
亲爱的Dialog,
Determine the interrupt source of wkupct_register_callback
I implemented wkupct_register_callback() and wkupct_enable_irq() to wake up BLE by an external interrupt pin. If more than 1 interrupt pins are configured in wkupct_enable_irq(), how can I determine which interrupt pins trigger the interrupt API? That means how to read the interrupt status. Thanks.
I2C voltages
Hi,
Here's a question on the edge between hardware and software.
I'm trying to use an accelerometer with our 14583-based board, and I'm seeing some strange behavior. Communication isn't working, and it may be related to the voltages being outside of tolerance for the chip. That leads me to the main question: What could cause the I2C SDA/SCL voltage to go to 3.3V? We have a pull-up on the I2C line, but it's only pulled up to 1.8V.
DA14583 SUOTA Operation
Hello support !
Could you please let me know about how to check the operation of SUOTA.
We are currently checking the operation with both DA14580 DEVKIT-B and DA 14583 DEVKIT-B.
I checked by the procedure of page 12 to page 14, page 21, page 22 of AN-B-10"DA1458x usin SUOTA Ver1.2".
When using DA14580 DEBKIT-B, the DA14580 device was detected correctly
on the device detection screen of the SUOTA application.
