SAME54 XPLAINED pro NOT detect

SAME54 XPLAINED pro

DEBUG USB 無法為windows PC device manager所偵測
依照使用手冊用USB轉microUSB cable, 應該能在device manager 看到COM port, 但是並沒有看到,且沒有掃描硬體的動作

在MPLABX IDE project property,connected hardware tool亦沒有靠到這塊板子

請問有何建議?

hi,
若不接外部MCU,以模組為主MCU,哪個模組可以增加應用到模組的FLASH?
例如OLED 模組,Button, Buzzer等

hi,
can you advise what the difference is?
if I have PIC18F26K80, which one to use?
or which one I can use it without external MCU?

which one has longer transimmison range?

MCU:ATSAME51G18A
MPPLABX IDE
欲使用CAN bus monitoring 相關OBD2資訊以顯示,發現有以下一影片:

CAN BUS基礎 & Harmony(使用ATSAMC21)– 實驗講解
==================================================

1. 此影片中所展示的CAN 相關source code可否分享?

2. 另外CAN auto detect baud rate用bus monitoring mode是否有相關範例參考?亦即不干擾CAN bus情況下偵測CAN bus的baud rate 及ID 的bit 數

3. 可否用CAN activity來叫醒sleep mode MCU?有相關程式參考?

MCU:ATSAME51G18A
MPLABX v5.45
Harmony v3

參考SAM2001使用TCC1 來產生PWM波形,但在但在configuration options 的選項不同
我是使用pin #29(PA20) function 選TCC1_WO4,不清楚對應關係?

1. select output matrix該如何選
2.channel configuration只有channel 0-3該使用哪一個?
3.Pattern generation有8個該選那一個?
4.outputs有八個該如何選?
5.dead time是何意思?在PWM波形的哪一塊?
