==DSO138==
'''Status:''' Managed to compile the opensource version and upload it to the device. The opensource uses the old R11 resistor value. Need to port the new resistor value to the opensource version. Currently radare2 sucks as reverse engineering the ARM thumb instructions. Heaps of the oscilloscope code is behind a binary blob.

* "Supports two types of TFT controllers (ILI9341 and ILI9325/9328)."
* Mine is a ILI9341...
* CPU is: [http://www.st.com/en/microcontrollers/stm32f103c8.html STM32F103C8]. Does not support DFU (usb bootloader).
