這真是個好問題,剛剛拿homepod mini 20W USBPD charger試了一下,其支援PDO只有兩組,分別為5V,3A and 9V,2.2A, 20W; 接上12V trigger, 輸出9V; 接上20V trigger, 輸出9V; 參考先前曾使用過的USBPD IC,會請求輸出能力範圍內最大的電源項目來看,這個trigger模組看來也是依循類似的機制。

請問一下,為了避免設計問題,我先拿兩片正常的arduino UNO照著影片的說明操作,但是出現以下故障 "C:\Users\Unid-RD\AppData\Local\Arduino15\packages\arduino\tools\avrdude\6.3.0-arduino17/bin/avrdude" "-CC:\Users\Unid-RD\AppData\Local\Arduino15\packages\arduino\tools\avrdude\6.3.0-arduino17/etc/avrdude.conf" -v -patmega328p -cstk500v1 -PCOM5 -b19200 -e -Ulock:w:0x3F:m -Uefuse:w:0xFD:m -Uhfuse:w:0xDE:m -Ulfuse:w:0xFF:m avrdude: Version 6.3-20190619 Copyright (c) 2000-2005 Brian Dean, www.bdmicro.com/ Copyright (c) 2007-2014 Joerg Wunsch System wide configuration file is "C:\Users\Unid-RD\AppData\Local\Arduino15\packages\arduino\tools\avrdude\6.3.0-arduino17/etc/avrdude.conf" Using Port : COM5 Using Programmer : stk500v1 Overriding Baud Rate : 19200 avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x60 avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x98 avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0xe0 avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0x98 avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x1e avrdude: stk500_getsync() attempt 6 of 10: not in sync: resp=0x98 avrdude: stk500_getsync() attempt 7 of 10: not in sync: resp=0x80 avrdude: stk500_getsync() attempt 8 of 10: not in sync: resp=0x60 avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x18 avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x78 avrdude done. Thank you. 晶片擦除失敗: 上傳錯誤: exit status 1 請問有人知道為什麼嗎? 不管拿有沒有燒過bootloader的晶片,都會出現以下回復
