E-ink screen ornament Sky Star development board

Overview

This is a 1.54-inch e-ink display, based on the Liangshanpai-SkyStar development board,
displaying a perpetual calendar, temperature, humidity, and air quality.
It's used for learning from the SkyStar STM32F407 development board and for circuit verification of the Orient Display 1.54-inch e-ink screen
. The circuit design is complete, but the inductor used had an incorrect package, requiring flying wire soldering.

The e-ink IC is the SSD1681, the same IC used in the Waveshare 1.54-inch e-ink screen. The Waveshare 1.54-inch e-ink driver has been ported, but the screen still doesn't light up. Further investigation is needed to determine if it's a hardware or software issue.

DSP solves industry problems
In the electronics industry, DSP high-speed computing is suitable for image and audio compression and encoding and decoding, but not suitable for running interfaces. ARM fills this gap. Therefore, amo

What to do if data is lost?
I believe that those who do embedded development know that non-volatile data storage is usually Flash, but there will usually be data loss. However, I have been thinking about what causes data loss. I
Some questions about uboot startup kernel
We know that the general process of uboot starting the kernel is: start.s-->start_armboot-->main_loop-->rum_command-->do_bootm-->do_bootm_liunx But some of the specific details are still not clear. 1.
RS485 receives garbled codes
I would be grateful if the expert can give me some advice! I am using Shengbo's CSD communication card, which has four independent serial ports, which can be set to any of rs232, rs422, and rs485. I h
