Espressif has recently released one wafer-level change on the ESP32 Series of products: ESP32-E. Below are the main design changes in the ESP32-E Series of chips:
1. PSRAM Cache Bug Fix: Fixed “When the CPU accesses the external SRAM in a certain sequence, read & write errors can occur”.
2. Fixed “When each CPU reads certain different address spaces simultaneously, a read error can occur.”
3. Optimized 32.768 KHz crystal oscillator stability, the issue was reported by the client that there is a low probability that under ESP32-D hardware, the 32.768 kHz crystal oscillator couldn’t start properly.
4. Fixed Fault injection issues regarding secure boot and flash encryption are fixed.
5. Improvement: Changed the minimum baud rate supported by the CAN module from 25 kHz to 12.5 kHz./改進:將CAN模組支援的最小波特率從25 kHz改為12.5 kHz。

1.Project: Make a Home-made Network Clock with ESP32-E/使用 ESP32-E 自製網路時鐘
Introduction:
This production will be very simple, getting the time from the internet via the wifi of the ESP32, and then you need to find a screen that displays the time. There are many options for the screen, LCD1602 or LED monochrome dot matrix for splicing. I accidentally saw a VFD fluorescent screen before, it was green-blue when it was lit, and it glowed with white light, which makes the whole screen a mottled beauty. So, I am going to use it here./
這個製作會很簡單,透過ESP32的wifi從網路上取得時間,然後你需要找到一個顯示時間的畫面。螢幕有多種選擇,LCD1602或LED單色點陣進行拼接。之前無意中看到一款VFD螢光屏,點亮時呈綠藍色,還泛著白光,讓整個螢幕呈現出斑駁的美感。所以,我將在這裡使用它。
