你再試試我改的!!!
我將CLRWDT拿掉!
BANKSEL 拿掉!
還改成只傳送一次!!
你的會一直傳送!!!

上了電池以後就有電了!!!
這時程式有在跑了!!!
但船不讓她動!!!
等到滑動開關切到on時,才讓船開始動!!!
這應該是玩具的基本動作,假如沒開關,就會一直耗電,不符合消費者需求!!!
你的船假設裝上電池後mcu就能準備動作了!!!
此時偵測滑動開關!!!
如切到ON!!!
1.就做你"g!"此動作!!
2.又或者改成直接偵測滑動開關即可,跳過接收到"g!"指令程式,
直接控制船動!!!

你的問題在十位數轉ASCII CODE!!!
123=495051(d)
97=5755(d)
查一下ASCII CODE就知道啦!!!

你可以用MAX3232接電腦,再用超級終端機!!!
這樣不管是接收或傳送,都可以很清楚的知道!!!

呵!!!
那是我用超級終端機時,可以在每兩個byte中間加一個','逗號!!!
方便我檢視資料用啦!!!
你可以不用啦!!!

你再試試我的程式!!!

那你就去偵測電源開關阿!!!
有動作的話就開始跑你的程式阿!!!

TXSTA設為B'00100100'
設PIE1&PIR1即可,不需再設PIE2&PIR2!
亦不需設中斷!
每個BYTE傳完最好在清一下TXREG!

VDD最好再加一顆104!!!!
MCU要能動還需reset pin 接10k到VDD!!!
還有選擇內/外部震盪器!!!
當然還須燒錄程式阿!!!

我選硬體流量的原因是...
我有將PIN4(DTR:data terminal ready)PIN6(DSR:data set ready)PIN8(CTS:clear to send)短路接在一起!
後來公司前輩有跟我說其實這樣就等於選擇無流量限制啦!
所以跟組合或C是無關的!
不過我有試過PIN4.6.8無短路在一起,傳送資料會有問題,會類似你的漏收問題,所以才會提醒你!
