Once completed, the software will display a "Success" or "Finished" message. Disconnect the device and power it on normally. Troubleshooting Common Firmware Issues

You will see a progress bar indicating that the memory is being erased and the new code is being written.

Ensure your DSO-TC2 has at least a 50% charge, or keep it plugged into a stable power source via your PC during the process.

Before diving into the update process, it is crucial to understand what the firmware actually controls. The DSO-TC2 runs on an ARM-based microcontroller (typically a Cortex-M3 or M4 core). The firmware is the low-level software that manages:

This handles the waveform display and high-speed sampling. Firmware files for this part usually start with the prefix CHD .

The is one of the most popular budget-friendly handheld test instruments for electronics hobbyists. Combining a 200 kHz single-channel digital storage oscilloscope with an automatic transistor component tester , it delivers high utility in a pocket-sized form factor. Once completed, the software will display a "Success"

The DSO-TC2 is an open hardware platform to a degree. For software engineers and embedded enthusiasts, you are not limited to official firmware. The device uses standard STM32F103 or similar. You can:

Once completed, the software will display a "Success" message, and the DSO-TC2 will automatically reboot into its normal operating mode. Custom Firmware and the Transistor Tester Component

This voids warranty and can brick your device. Always back up the original firmware before attempting. Ensure your DSO-TC2 has at least a 50%

While holding the button, connect the device to your PC using the USB-C cable.

The EEVblog forum has a massive thread dedicated to these oscilloscopes.

To accept new firmware, the device must be placed into a special programming mode. Turn off the DSO-TC2 completely.

The DSOTC2 entered the market as a budget enigma. Unlike traditional oscilloscopes that rely on expensive, specialized analog front-end chips, the DSOTC2 was built around a microcontroller and an FPGA .
