: Some users have tried to port open-source "TransistorTester" firmware to the device, but hardware limitations—like the way FNIRSI integrated the MCU—often make these third-party stories end in failure. How the Process Usually Goes (For Other Models) If FNIRSI were to release a update, the narrative would likely follow the path of the fnirsi dso-tc2 firmware
This open-source foundation explains both the strengths and weaknesses of the tester side. The firmware reliably identifies thousands of components, measures parameters like hFE (transistor gain) and Vf (diode forward voltage), and displays pinouts—all within seconds. However, the legacy code also introduces peculiarities: the tester can be confused by very low-value resistors or high-capacitance capacitors, and it occasionally misidentifies complex components like JFETs. The firmware does not improve upon the open-source algorithms; it merely repackages them. In this sense, the DSO-TC2’s firmware is a compilation rather than a creation —a pragmatic choice that keeps development costs near zero. [2] Chen, Z
: The device should appear as a removable "U-disk" or a virtual COM port on your computer. Drag & Drop : If it appears as a drive, simply copy the firmware file into the root folder. : If it appears as a COM port, use the FNIRSI PC Software to select the port and "Start Upgrade".
