Daughterboard
comming soon :) git repo
Components:
Diode: Standard types (like 1N4007) will work
Resistors: 2k2 and 22k, 0,1%
Caps: Low ESR type, 10-50µF
Firmware Flashing
FLASH_MODE=STLINK is set as default
STM32F4 Discovery can mainly be programmed in two different ways:
STLINK
- with onboard STLinkV2 over SWD
- required hardware: usb to mini USB cable
- required software: st_flash and st_util from Texane
- more information: STLink page
DFU-UTIL
- with the MCU native (embedded in rom) DFU USB bootloader over the micro USB AB connector
- required hardware: USB to micro and USB to mini usb cable
- required external software: dfu-util
- push MCU in DFU mode: connect mini(for power) and micro USB to PC, connect pin BOOT0 with 3V, press reset button(LED LD7 should light up now), disconnect BOOT0
- more information: DFU page
