171 | 171 | Implemented power supply bypassing according to SiLabs' recommendations: |
172 | 172 | - added 4.7 uF in parallel to C1 |
173 | 173 | - added 100 nF in parallel to C2 |
174 | - results: | |
175 | A test run initially showed about 10% abnormal cycles. Detailed | |
176 | observation, starting with first anomaly: | |
177 | ||
178 | - turn-on cycle: CH2 LED green, M1 not powered (CH2 fully off ?) | |
179 | - 21 normal cycles | |
180 | - turn-on cycle: all LEDs green, no power (LEDs didn't go dark as they | |
181 | would in DFU wait, so the MCU didn't reset) | |
182 | - 8 normal cycles | |
183 | - turn-on cycle: MAIN and CH2 LED green, M1 not powered | |
184 | - 31 normal cycles | |
185 | - turn-on cycle: all LEDs green, no power (not a reset) | |
186 | - 12 normal cycles | |
187 | - turn-on cycle: all LEDs green, no power (not a reset) | |
188 | - 3 normal cycles | |
189 | - turn-on cycle: all LEDs green, no power (not a reset) | |
190 | - 3 normal cycles | |
191 | - turn-on cycle: all LEDs green, no power (not a reset) | |
192 | - 3 normal cycles | |
193 | - turn-on cycle: all LEDs green, no power (not a reset) | |
194 | - 68 normal cycles | |
195 | - turn-on cycle: all LEDs green, no power (not a reset) | |
196 | - 5+ normal cycles | |
