AC696N GPIO quick reference. APIs: gpio_set_direction (1=input,0=output); gpio_set_pull_up; gpio_set_output_value; gpio_read; gpio_set_hd0 (1=strong drive); gpio_set_die (0=analog for ADC). USB: usb_iomode(0). Output high level = VDDIO voltage. Test each pin with multimeter on dev board. #JieLi #AC696N #EmbeddedSystems

Bluetooth speakers and headphones often need more than the chip's built-in resources. The JL JieLi AC696N's SPI interface allows you to add external Flash, an LCD display, and RGB LEDs.
All these configurations can be validated on the AC696N development board before porting to custom hardware. Once working, they significantly expand the capabilities of your audio product.

The serial port is your eyes in embedded debugging. On the JL Jieli AC696N chip, I've set up UART0 to print logs at 1M baud (configurable to any pin) – logs fly without stuttering.
Full configuration steps and code snippets are in the article. If you're working on audio products with AC696N, this workflow will save you hours.

Timers seem simple until they cause mysterious power drain or timing issues. The JL JieLi AC696N SDK provides two timer systems with different characteristics. Here's what I've learned debugging on the dev board.
Practical Tip
Test both on the AC696N development board. Add serial prints to see which thread the callback runs in.Both timer systems support one-shot timeouts—choose whichever fits your context needs.

Moving beyond basic low-power configuration on the JL JieLi AC696N, there are three advanced power management settings that can prevent intermittent crashes and improve user experience. Here's what I've learned while debugging an SD-card-based audio product.
All of these can be validated on the AC696N development board before porting to custom hardware. Taking the time to tune them saves weeks of field debugging.

The analog section of a Bluetooth audio SoC is where careful design pays off. Notes from the JieLi AC695N/AC696N guide:
For the DAC outputs, they recommend reserving positions for small inductors (100nH, 120nH, 220nH, 330nH) to form filters that can suppress high-frequency noise, specifically called out as TDD noise from a nearby mobile phone during calls.
