Da14681 External Flash Choices AN-B-045
Hello,
in AN-B-045 the supported Flash devices are listed. Are these really the only ones I can use?
他们太贵nsive for me. Could I use an other spi flash e.g. LE25U20AMB-AHOSCT-ND ?
Thanks
Microsecond Resolution Timing
Timer1 is reserved for the FreeRTOS ticks, which is running with the 32 kHz clock giving a resolution of ~30.5 microseconds. If I wanted to get the current execution time in a smaller resolution of microseconds, is there somewhere where the 16/32 MHz XTAL or 48/96 MHz PLL ticks are stored? The only place I could find to change the RTOS clock was dg_configUSE_LP_CLK in custom_config_qspi.h which modifies FreeRTOSConfig.h, but it seems that only choices are the 32000, 32768, and RCX (10.5 kHz) clocks.
DA1468x ADC Questions
Is the ADC clocked internally with a 200 MHz or 20 MHz clock? The datasheet mentions a 200 MHz clock, but the sampling time calculations are done with ADC_CLK=20 MHz, and I’m not sure where 20 MHz came from? If I choose the digital clock, does this mean the ADC uses the PLL instead as the SAR clock?
DA14680和14681从Flash加载程序的操作兼容吗？

你好！
我想购买DA14680的评估板，并使用片上Flash存储固件及需要掉电保存的数据，但官网只有DA14681的评估板。
如果使用DA14681+外部Flash芯片开发，程序、BOOT流程与DA14680+内部Flash兼容吗？
或者将评估板子板的14681替换为14680芯片，管脚兼容吗？
最后，DA14681-Pro评估板的子板上是不是没有Flash芯片，需要自行购买、焊接？
谢谢！

如何将程序烧录到spi flash中
hello dialog：
我的external tools 没有program_qspi_jtag_win这个选项
请问我该怎么做，怎样才能把程序下载到spi flash中（当前程序已经编译通过，并且可以在ram中运行）
谢谢
DA14681如何使用printf
中间看到很多宏定义，用于控制HW_UART，经过一段时间的调试，我现在可以用hw_uart_write_buffer查看打印了。
但是现在没办法使用printf，console又涉及到一堆的宏，不知道怎样才能打开console，有这方面的资料吗？
14681 Advertising Application
Hi There,
I have a simple question about running the provided "BLE advertising application" on the DA 16481 Pro-development kit. I am basically following the procedure described on page 41 (Section 7.5.1) of the DA 1648x Software Platform Reference (UM-B-044, attached here). While I can located all the codes and scripts I am not sure what the following line in the 2nd paragraph of page 43 refers to: "running this project using the same procedures described in previous sections ...".
