J-LInk Troubleshoot Document
Forums:
A new Jlink related document has been released (AN-B-052:DA1458x/68x Development Kit Jlink interface) regarding some malfunctions that have been observed with dialog's development kits due to the automated update procedure of the Jlink driver. The document is located under the 58x/68x application notes pages.
Thanks MT_dialog
DA14681 power consumption is high
Hi,
My PCB USES DA14681 and other peripheral chips, which are powered by GPIO of DA14681.
When DA14681 is in extended sleep mode, GPIO power is turned off, and the battery output current is 102uA. In DA14681 hibernation mode, the battery output current is 1.4uA.
Some PCB extended sleep power is abnormal, battery output current is 1.9mA, but hibernation power is normal.
I wonder if the power anomaly might be related to DA14681.
AD1468x - SPI Half Duplex
Hello
I do need to communicate with a SPI peripheral that requires SPI Half-Duplex communications.
Can you confirm to me that this is possible with AD1468x and how ?
Is complex SPI transaction with callback functions between read and write transactions in which we toggle GPIO PIN Function from DO to DI suitable ?
Thank you in advance
can't wake up form hibernation by VBUS_Handler
Hi DA team
In the previous post you told me "The DA14682 can wake up form hibernation via the VBUS (USB) interrupt."
But I can only wake up via the wkup button。
I plugged in the USB while sleeping and did not enter the VBUS_Handler。
I can only do the following configuration:
hw_wkup_init(NULL);
hw_wkup_configure_pin(HW_GPIO_PORT_1,HW_GPIO_PIN_6, 1, HW_WKUP_PIN_STATE_LOW);
hw_wkup_register_interrupt(button_interrupt_cb, 1);and in button_interrupt_cb is：
Cannot wake up after enter extened_sleep
HI DAteam
i set
---------------------------------------------------------------------------------------------------------------
hw_wkup_init(NULL);
hw_wkup_set_debounce_time(32);
hw_wkup_configure_pin(HW_GPIO_PORT_4, HW_GPIO_PIN_1, true,HW_WKUP_PIN_STATE_HIGH);
hw_wkup_register_interrupt(wkup_handler, configLIBRARY_MAX_SYSCALL_INTERRUPT_PRIORITY);

and the wkup_handler is
AD1468x - GPADC in Continous Mode ?
Hello
I need to acquire 2k samples from the ADC for a sensor application.
The BSP does not seem to implement the ADC continous mode.
Can you please confirm to me that this is still the case ? Can you also provide me a planning for that feature ?
Thank you in advance
Add custom USB Class
Hello,
I'm using a DA14683 and I would like to use the USB CCID Class. However, the SDK does not provide it, so I would like to know if there is a way to add a custom USB Class implementation using the SEGGER interface.
Best Regards
No 16Khz Crystal Configuration
How do I configure custom_config_qspi.h given that my circuit has no 16khz crystal?
The system appears to attempt to use the 16khz crystal before switching over to the internal crystal. A few seconds later, the app closes with an "unhandled exception." Since this board has no 16khz crystal and the development daughter board does, I'm assuming this is the issue.
The code works perfectly on the deveopment daughter board but fails on my board with no 16khz crystal.
I've changed this setting from LP_CLK_32000 to:
