CH552 CMISIS DAP about ch55xduino

[DeqingSun]

It seems you are using a newer chip. I'll check if ishiyakazuo/ch55x-isptool@151c55e works.

What you mean usb port? It should appear as an HID device.

@DeqingSun I have bootloadwer 2.4, it can be that?

when the chip is in bootloader mode it appears the device USB and I can program with wchisptool, but when I load the compiled example, everything disappears

With bootloader 2.4, I can't upload directly from arduino

@DeqingSun work for me, but i can't get a blink

My schematic work at 3.3v

[DeqingSun]

I just compiled the 2 versions, would you also try if my file worked for you?

Try to use 5V for main chip to see if the USB work properly. CH552 may not work at 24M with 3.3V power supply.

CMSIS DAP working for 12Mhz

[DeqingSun]

Good, you may use 16M, that will be a bit faster.
