请教下，关键词DA14580芯片的发出/接收接收：
https://support.dialog-semiconductor.com/connectivity/product/da14580
描述为之
“Radio current consumption: 4.9 mA RX / TX at 3 V at 0 dBm output power”
而在最新的数据手册《DA14580_DS_3v4.》中
描述为之
“Supply current at VBAT3V:
TX: 3.4 mA, RX: 3.7 mA (with ideal DC-DC)”
两者有什么区别（为大小会有差异）？谢谢！
我上传了5.0.4 UART2_ASYNC KEIL项目。我建立了它，然后ran r r r次命中运行。
I am simply running in a while(1) loop:
uart2_print_string("A").
I have probed the pin P0.4 (port 0, pin 4) which is the default in the program with only one time it was actually printing something.
I then changed it to Pin 0.2 (port 0, pin 2) and I see nothing.
I also tried changing the baud rate to 9K6 instead of 115K2.
I am trying to program the bluetooth DA14580 chip and having a really hard time altering the example code in the 5.0.4 SDK.
The code is really robust I am sure but it is very tough to understand what is going on as when I go down one rabbit hole, it leads me to 5 others. Is there a tutorial online to help me program these chips. I really like writing my own embedded code like with PICs, but I can tell I will have to use some of the SDK code for at least the bluetooth aspects.
Any videos preferably?
Hi,
in our product, we are planning to store some sensor data locally when not BT connection. The storage size required for us is several MB's. So we are planning to use microSDcard.
What all is required to interface SDcard to DA14580?
Since the SDcard has SPI interface, can DA14580 be used to write and read data?
What are the other possible solutions to store the data locally?
Thank you,
Bharath
Hi Dialog Team
我使用自己的自定义,电池操作, Buck Mode , Da14580 with external flash with DSPS Device Project , added i2c driver ( SDA , SCL with pull up register - 10K connected to VBAT3v), Once data send to Master BLE device , DSPS Device disconnect and enters into extended sleep , I have checked the power consumption using Digital Multimeter(DMM) ,
Advertising - 512ua ,
connection , data xt - 776ua
Sleep - 322ua ,
Hi,
I am now able to populate the advertisement data and GATT services and characteristics using ke_send_msg and handle the events in user_catch_rest_hndl(). Although, I have done this in a hard coded manner.
hello dialog：
我使用jlink去使用命令行的方式去烧写OTP，可以无法烧写成功，我6.8V有接。。
我的命令是：SmartSnippets.exe -type otp -chip DA14580-01 -jtag 123456 -cmd write_custom_code -file "C:\5920_0300.hex" -offset 0x0000 -y
但烧写最后提示otp内存刻录失败。
请问下这问题会在里里，是我的命令错了，还是还需要先烧写步骤？
Hi,
In our application we have a peripheral connected to DA14580 through SPI interface. It generates 250 interrupts per second and in each interrupt we have to read 19 bytes of data. So roughly we get 5KB of data. We have to add some error handling bytes to this data and transmit it to the android device. So the rough final data size is 6KB per second. Now we are using the through_eval_periph example in our project. But we are seeing that there is a loss of data also observed that the data transmission stops for 1 or 2 seconds and then continues.
尝试在PLT中写入时，会发生以下错误。
DUT_PDLL_XTAL_TRIM_FREQ_CAL_NOT_CONNECTED | FAIL | XTAL trim could not be performed. Could not detect external input frequency. Current device status = [34].
What can be considered as a cause?
电路：电路应与DA14580DEVKT-B +加速度传感器+外部SPI闪光灯相同
XTAL Trim: enable
GPIO input pulse pin: P0_3 (shared with UART RX)
Externally output pins: VBAT 3, GND, P0_2 (TX), P0_3 (RX), VPP, SW_CLK, SW_DIO
Hi:
I use the DSPS device SDK. Set sleep_state_t app_default_sleep_mode = ARCH_EXT_SLEEP_ON in the user_config.h file, define CFG_MEM_MAP_EXT_SLEEP and set adv interval 3s.But the device always has an offset value approximately equal to 2.3mA and never reach the sleep current of 2uA or less. The DA14580 device has got less 2 uA with SDK3.0.8. What wrong with the DSPS device SDK.
谢谢。
