Re: Missing button response
sch-1.jpg Photo-1.jpg sch-2.jpg Sorry for the long delay... I am back on this project.... I have measured everything in the V/DIV circuit... The only thing found in error was the resistance reading across R-26... It is supposed to be 10 K, It measures 5K. I replaced the resistor with another 10 K r...

OK, I have read the link that states you will sell an updated board for $18 with the -50 software... Does the board have all components mounted, the SMD's mounted, or nothing mounted? If only the SMD's are installed, and remaining parts are supplied (so I can enjoy re-soldering the board...), May I ...

Re: DSO138 firmwareupdate
Success! Thank you! Problem with SEN2 was traced to resistor R23 not being soldered correctly to one end... (Thank you for including a spare. The original SMT resistor is now located somewhere within my carpet). Problem with flash programming was with a poor crimp connection on one of the UART conne...
