stm32flash -v -b 115200 /dev/ttyUSB0 -w 113-13801-061.hex r2 ../src/firmware-src/libdso138.a -b16 -aarm -AA
- "Supports two types of TFT controllers (ILI9341 and ILI9325/9328)."
- Mine is a ILI9341...
- CPU is: STM32F103C8. Does not support DFU (usb bootloader).
- Calling the STM32 SystemMemory Bootloader from your application
- how to use STM32 system memory boot modes

- Post on bare STM32 dev
- USB HID on STM32F042
- This might be about the bootloader...

Capacitors
This info on LM1117 capacitors....
- The minimum output capacitance required by the LM1117 is 10µF...
- The ESR of the output capacitor should range between 0.3Ω - 22Ω.
I have:
- Polyester Film - 1nF->470nF @ 100 Volts
- Polyester Film - 1nF->68nF @ 630 Volts
- CBB Polypropylene Metal Film - 1nF->2200nF @ 630 Volts
- 0402 SMD Ceramic - 50 Volts
