[Solicitation Order] Dual color temperature and high color rendering WIFI desk lamp ESP8266

Overview

It’s the first time to use ESP8266, and it’s also the first time to use Arduino. If you are not familiar with it yet, use Dian Deng Technology’s APP first. DIY a simple and practical desk lamp.

Renovate a desk lamp you bought earlier and use its shell. Change to a WIFI desk lamp with high color rendering, dual color temperature and adjustable brightness.

Encoder and mobile APP dimming. 5V 1A or above power supply. The power is about 5W.

Two-way constant current DCDC dimming, non-PWM direct dimming, the light does not flicker.

Hardware parts:

The main control uses ESP8266 and Essence’s module ESP-12F.

Onboard is a ch340 serial port to USB, automatic download circuit.

The LED driver part uses two SGM3732 to boost constant current drive. Drive two LEDs with color temperatures of 6000K and 2700K respectively. LED is 6 series 4 parallel × 2.

One NTC is used to display the local temperature.

The motherboard and key board are connected using FPC 12P 0.5mm cable.

The key board has a rotary encoder and RBG light for manual dimming and status indication.

CButtonST class loses focus and flickers under EVC
I downloaded a CBottonST class from the Internet and found that when the button loses focus, it will flash? Has anyone used this button? How to solve this problem? Urgent! ! ! ! ! ! ! ! ! ! ! ! ! !
Received the board report
I received the board. Thanks to Renesas and eeworld. I'm busy with work recently. I'll start tinkering with it. Here's the picture
This is an idea of ADC, let’s see if it can be realized.
Known conditions:1. I use the internal ADC of stm32f103vct6, and connect an external SPI FLASH M25P64 for data storage;2. My purpose is to do continuous ADC conversion and save, and the ADC conversion
Special application for board trial
Most of the company's projects require the use of FPGA and CPLD. Recently, a project requires a higher-end FPGA, so I want to apply for a trial first. The new project requirements will be carried out
