Introduction: Reviving the DSO138 DIY Digital Oscilloscope Kit

My DSO138 DIY Digital Oscilloscope Kit had a trouble in the firmware update. And it did not work anymore.

Even following these instructions it was not possible to revive the DSO138 DIY Kit ( http://www.jyetech.com/Products/LcdScope/DSO138_oscilloscope_upgrade.pdf )

Step 1: Solution

After several attempts to fix the problem, here was the solution: My step is to just download stm32flash (https://sourceforge.net/projects/stm32flash/) and using the command:

Stm32flash -w 113-13801-061.hex -v -g 0x0 COM3

COM 3 is my USB TTL converter.

Step 2: Tools

DSO to USB TTL connections:

GND to GND

TX to TX

RX to RX

Some of the files mentioned must be downloaded . The url's wont load to comments so you need to put them in the instructable . In particular the hex file you uploaded to the oscilliscope

I'm sorry for not mentioning, but you can download it from the manufacturer's website, the link is in the instructions document (http://www.jyetech.com/Products/LcdScope/Firmwares_138.php).

Arn't they nifty devices . Bloody cheap and excellent clear plastic boxes . I recommend them to anybody that does not have one

Yes, I agree ... I bought it too.
