Fnirsi Dso-tc2 Firmware

One of the most important things to know before updating your DSO-TC2 is that it uses for its two primary functions:

is based on the popular "transistor tester" project, there is significant community interest in porting or improving the software EEVblog Forum

Future work includes full decompilation of the component tester state machine and porting an open-source oscilloscope firmware (e.g., ScopeFun lite) to the DSO-TC2 hardware.

If you need to update both the CHD and CHT firmware, repeat Steps 1 through 5 for the second file. fnirsi dso-tc2 firmware

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