Is it possible to set dual-purpose pins using these tools?
RECONFIG_N and DONE pins need to be set to dual purpose to use UART to CH552 on the Tang Nano.
Configuring dual-purpose pins/pin multiple…

Hi I just found this project and I'm curious if it is possible to write to a CH552 chip?
I got it compiled and captured the USB transaction. It seems the "Set Flash Address" command from WCHISPTool…

When you press the Write button, the ArduinoIDE will display an error.

CH552 UsbSerial can communicate properly with 230400 baudrate on 24Mhz,But Serial0 can not,I can use with 115200.
Which can communicate with 230400 in CH55x?

It worked really fine, but once the file size gets over around 30kB, it starts failing on verification step.
I confirmed that the official tool can write the same binary without any error.
Also, the…

We have having some trouble with the CH552 chips, programmed via the Arduino IDE, becoming unstable if the supply voltage drops too much, rather than reverting to a consistent off state. Does anyone c…

I wanted to use a CH552 and a seven-segment display using a 74hc595 shift registers.
On stm8s103f3p6 (sduino) it works fine, but ch552 doesn't even compile.
I get errors:

USB light controller currently using LGT8F328P and it's a huge chip, need a bootloader to upgrade firmware using UART
In other side CH552 is a dirt cheap MCU which capable of full speed USB (tested w…
