Fnirsi Dso-tc2 Firmware ✭ «TOP-RATED»

If you buy a DSO-TC2, check the firmware version immediately. If it’s below v2.0, consider updating. And always treat the oscilloscope readings as rough indicators—for serious analog design, reach for a bench scope. For the latest firmware files, visit: fnirsi.com/support or search “FNIRSI DSO-TC2 firmware” on EEVblog forums (community mirrors).

| Issue | Firmware Version(s) | Workaround | |-------|--------------------|-------------| | Auto-set sometimes freezes | v1.x, v2.0 | Manual vertical/ horizontal adjustment instead | | Capacitance reading drifts | All versions | Short probes, then measure twice | | Saving screenshots fails | v2.1 | Reformat SD card, save as BMP not PNG | | Waveform refresh rate lag | All versions | Accept ~30-50 fps; it’s not a high-end scope | fnirsi dso-tc2 firmware

Always check your current firmware version: Menu → System → About. Unlike the popular FNIRSI DSO-150 (which had a hacked open firmware), the DSO-TC2 has no known fully open-source firmware replacement . The reason: the transistor tester hardware is proprietary, and the ARM bootloader is locked. Some hobbyists have dumped the firmware via SWD (Serial Wire Debug) pins, but reverse engineering is complex due to code obfuscation. If you buy a DSO-TC2, check the firmware version immediately
