1.0.7 (prerelease)

This release brings two big changes 👍

• Better frequency computation
• Usb support

For the USB support to work, you'll need a micro usb breakout board and a few resistors (see the wiki for details)
The PC software is python3 based, nothing to compile. It has only been tested on linux. You'll need python3, Qt5 and pyQt5.
See https://github.com/mean00/DSO_STM32Duino/tree/master/pyDSO

1.06

• Use timer for most timebases except 5us/div and 10us/div => much more accurate
• No longer using bootloader !
• General speed-up
• Fixed some bugs around trigger
• Use M4 FPU for GD32F303
• Can overclock STM32 to 128 Mhz using -DMCU_SPEED=128000000
• Overall stability

The only that is not working too well is the 5 us/div due to fast interleaved mode.
The files you probably want are :

• Dso150STM32F103_vanilla.bin if you didnt modify the rotary encoder
• Dso150STM32F103_usb.bin if you connected the rotary encoder to PB14 and PB15

1.05

• Support for both STM32F103 and GD32F303
• General stability fixes
• Support for 5 us / div
• Rotary encoder moved to PB14 and PB15!

Use the same bootloader as previously

Accuracy

Fine voltage calibration
Better use of ADC range to improve accuracy
Improved UI for calibration & fine voltage calibration

1.3

• Fixed task priorities, much more responsive rotary encoder
• Pseudo "triggered" led

Usage same bootloader as version 1.0

1.2

• Updated to gcc 8.2
• Fixed most of the deadlocks
• Long press on "OK" does an auto setup

Please use the same bootloader as in v1.0

Demo 2 (v1.1)

Fix deadlock
More accurate frequency meter
Better calibration

Please use the same bootloader as in demo1

Demo 1

Still buggy, but usable
You'll need to flash both files, see the wiki to see how (stlink v2 or blackmagic needed)

• pb7 is just a stm32duino bootloader
• Dso150 is the app itself, for unmodified rotary encoder
