DA16200 Hongjia HJ-DA16200
Small size is critical for many IoT applications. SiP (System in Package) allows IoT device makers to reduce the size of their electronic circuit hence achieving a small form factor for their end products. Dialog’s partner Tangshan HongJia Electronic Technology Co., Ltd. has developed an ultra-small, ultra-low power Wi-Fi SIP module with Dialog’s DA16200, the world’s most power-efficient Wi-Fi SoC. The HJ-DA16200 delivers the same long battery life and low power consumption offered by DA16200 module but in a much smaller form factor.
The fully integrated SIP consists of the DA16200 SoC, 2MB or 4MB flash memory, RF components including crystal oscillator, RF lumped filter, and an antenna. The built-in antenna is sufficient for normal application, and the external antenna can also be extended. Support customer 2-layers PCB design.
The SIP has 40 pins in 8 x 8 x 1.3mm LGA package including GPIOs, JTAG, RTC control, UART, power input and Antenna Pin (optional to use external antenna).

quadrature decoder interrupts not working properly
Posted by1user35 points 8 repliesI connected a rotary encoder to the dev kit pro and tested it with the quadrature_decoder example. In polling mode it does work perfectly and the X value changes every "click" of the rotary encoder. The ISR reports on the other hand are very irregular and usually show up every 3-5 "clicks" of the rotary encoder.
Do you have an idea what the issue could be?

Hi There,
According to our Team internally, the event counter isn't cleared in the interrupt. Please try to clear the event in the quad_decoder_user_callback_function as follow :
SetBits16(QDEC_CTRL_REG, QDEC_EVENT_CNT_CLR, 1);// Clear event countLet us know if this helps to fix that issue.

Hi There,
Could you please let us know if this resolution solved the issue?

Now the Interrupts fire way more often but still irregularly. Usually about 2-6 ISR reports are sent every "click". And sometimes but rarely 0.

Hi There,
This sounds like contact bounce – Our setup had some issues with that too. Adding a debouncing circuitry fixed it.

Ok, I tried it with the debounce circuit attached below and it made it much better but still not perfect.
Could you let me know what debouncing cicuitry you used?

Hi There,
Thanks for posting your question on our new forums. I have escalated this internally, so I'll get back to you ASAP.
Thanks, PM_Dialog
