Overview:
The offline programmer is an offline programmer used for batch upgrades of WCH series chips. it does not reply on computers.it is used in mass production and is not a debugging tool.
Note1:
The offline programmer has two volaages:3.3V and 5V.The external power supply is determined by the chip
holder. For example:the ch57x holder is directly connnected to the VDD_3.3 pin of the chip,and the offline writer
selects 3.3V;For the CH55X/CH54X series ,the writer output voltage selects 5v.
Note 2：
The current factory programmer version (3.3V/5V) only support CH32Vxxx series chips(v2420v).If you need to use a programmer to program ch32Fxxx series chip,you need to upgrade the programmer firmware(V2420F)
Note 3:
The WCH-MCU-DL be designed of CH32V208 support V003 series chip programing.And the programmer support all series chip.
Note 4:
The WCH-MCU-DL need to dirtectly connnect chip when download program by usart/USB/SWD.USB port can not connect chip by HUB when download program.
