USB to TTL fully universal automatic downloader

Overview

Use CH340G and lead out common pins, and select 5V and 3V download modes through jumpers.
Using the type-c interface is more versatile, and you can download it with just a C port data cable.
If you use a chip such as Atmega328p LGT8F328P, directly short the pin header to 5V mode, as shown in the picture, and then RSTconnect the chip pins to the downloader DTRto achieve automatic downloading.
If you use a chip such as esp8266 or esp32, directly short the pin header to 3V mode, as shown in the picture, and then connect the chip ENor PDpin to the downloader DTR. For esp8266 and esp32, GPIO0ESP32-C3 is GPIO9connected to the downloader RTS, and automatic download

LPC1114 Debug SSP
Unfortunately, LPC1114 only has one serial port, which is not very convenient to use. Now I adjust the SPI, which is called SSP communication here, to control the wireless chip to send data. It is not
I have a question
I am a DSP novice, and I have a question for everyone. How can I load my own program into the main program so that it can be called by the main program? Please explain the process in detail, thank you
Oscilloscope development, don’t know where to start?
I want to make an oscilloscope that can store about 500 waveforms, and use an LCD to display them. The time sampling unit is in microseconds. What chip should I use? No one in my company makes the boa

About the problem of direct operation of NandFlash by application program
Due to project requirements, it is necessary to provide the application with an interface for directly operating NandFlash. I found some articles on direct Flash operation on the Internet and tried it
