The PY32 offline programmer currently supports chip models in the PY32F002A/002B/002/003/030/071/072/040/403/303 packages and XL32F001/003. The PY32 offline programmer uses a MINI-USB interface, providing a stable physical connection. The device communicates with the computer via a serial port, with a fixed baud rate of 1M. It must be used in conjunction with our host software. The programmer only provides 3.3V SWD programming. It needs to connect to SWD_VCC, SWD_GND, SWCLK, and SWDIO, which correspond to the VCC, GND, SWCLK, and SWDIO of the chip being programmed.
The PY32 offline programmer supports loading firmware in both “.Hex” and “.Bin” formats, but can only save one firmware at a time. After selecting the chip and loading the firmware, you can check and configure options such as limiting the number of programming times, programming write protection, programming configuration items, sector erasure, SDK settings, ID encryption, and rolling code programming according to your needs.The PY32 offline programmer features a user button located at the lower left of the programmer. In the programming interface, this button can trigger the download to test whether the programming process is functioning correctly and to verify the signal communication with the machine. In the loading interface, a short press will exit the loading interface and restore the programming working state.The PY32 offline programmer is equipped with a display screen that can show the firmware checksum and the number of successful and failed programming attempts.
