ESP32 PicoD4 USB plug-in minimum system development board

Overview

You can directly plug in the USB for programming, eliminating the trouble of data cables. The esp32 packaged in pico-d4 is compact and can be plugged into a breadboard. It has an automatic download circuit and is pin-compatible with Wemos Lolin32 lite, but introduces Vin and +5V pins to facilitate breadboard development and expansion board power supply.
The project has been verified and works fine. Note: Do not use pins 16 and 17 when writing code, and do not use UART2 directly. Just replace pins 16 and 17 with pins 9 and 10.

E22-400TBL-01 LoRa module test version + 02 initial test
I took advantage of my spare time to try to see the data transmission and reception of E22-400TBL-01. E22-400T22S_UserManual_CN_V2.7 on the EBYTE website explains that the module has four modes, and t
Why? The 32768 in MSP430F2001 does not oscillate
The internal clock of MSP430 is configured, but the 32768 in it does not oscillate because there are devices connected to the outside of xin/xout. I would like to ask how to use the 32768 clock when t
About the IP address routing of the WiFi module
What is the IP address of the WiFi module? IP is the abbreviation of Internet Protocol, which means "protocol for interconnection between networks", that is, a protocol designed for computer networks
DSP2812 code is blocked by compiler problem
[size=4]Recently, a colleague wrote a program with more than 2000 lines. All the codes were placed in one file. The length of the .text segment was 0x20a0, which exceeded 8k. So he had to block part o
DSP TMS320F28335 interrupt vector table
Since the addresses corresponding to each interrupt source of F28335 are set in advance and cannot be changed, we must prepare an interrupt vector table.It can be seen from the figureINT1-INT12 each c
(3) UART DMA plus IDLE interrupt indefinite length byte reception
The amount of data received by radar applications is relatively large, so DMA is needed to increase the speed and reduce the MCU load. The previous project has used DMA+IDLE interrupt on the STM32F103
