How to start with CH32V003 ? #34

Closed xcom169 closed 2 months ago

xcom169 commented 8 months ago

Hello All, I bought and soldered the CH32V003 product, however when I plug it onto a USB port nothing happens. I can't see any now device in Windows. On Linux there is nothing in dmesg. Only a blue LED is blinking on the board. How to start the device? Or is it faulty?

I also tried Ardunio IDE but nothing happens with it either. The model is: WeAct CH32V003F4U6

I don't think there is any USB chip on that board https://external-content.duckduckgo.com/iu/?u=https%3A%2F%2Fae01.alicdn.com%2Fkf%2FS79da539b6b564dbc92dd1bc2b869e99bj%2FWeact-ch32v003f4u6-ch32v003f4-ch32v003-ch32v0-ch32-RISC-V.png&f=1&nofb=1&ipt=ed2f085d369bc700fec98f3dc68f861b0e5e3f9859740a8ccda75c844c0f8267&ipo=images you need an external USB to serial converter.

Hello. Thanks. Do you mean that USB-c is just for power nothing else?

CH32V003 doesn't have usb, you need another USB IC for that, if it's not on the board then USB is only used for power.

Thank you Árpád!

I have a USB to TTL-serial converter at home. On the board are the DIO,NR, GND, VCC pins the serial pins? Should I provide the 5V power over USB or via serial ?

You need a WCH linkE programmer if you want it do something, it also has built in UART.
