Work-around: Put resistor in parallel to C94. Start with a value of 56k - this seems to work in most cases. If board does not start increase value slightly. The same approach is used BTW in the commercially available Disco F746 prototype board. === Change brightness of LEDs === Helle LEDS: Mit den Bausatz-Vorwiderständen leuchten die LEDs sehr hell. DF9EH hat die Werte reduziert: * R36 auf 22,6k (D1 grün) * R37 auf 6,8k (D2 rot) * R116 auf 6,8k (D3 blau) CKG Edit en/ovi40build/uiboardbuild.txt Last modified: 02.03.2018 18:13by df9ts_user
