我設置Timer3 2ms overflow並產生中斷時,可以看到 io toggle輸出, 取消Timer3中斷後,我在timer1 mcc 的設置中,設置 Clock Source並選擇Timer3 Overflow,好像沒作用?
我又試著把Timer3 Overflow 輸入到 CLC1 ,並令CLC 輸出在 raseing 時中斷, 也是可以看到 io toggle輸出,然後在timer1 mcc 的設置中,設置 Clock Source並選擇CLC1 output,但也是沒作用?
單獨將T1設置為FOS/4,是可以正常中斷並Toggle io輸出.. 請教先進..我少設定了什麼嗎??
我想用timer來產生1hz ~ 1khz 的波形,以1/32Mhz(0.03125us)的週期為timer的clock輸入..看設置好像可以把timer結合..但timer1的clock source設置好像都不成功...
