有圖有真相, 規格書是說工作電壓4.5到5.5V , 我用3.3V 驅動 照樣可以用

以前都用 20pin的j link ,它體積有一點大,改用st link 體積明顯變小較不占空間,而且只需三條線

mcu顯示介面是用七段顯示器的話,就要考慮掃描時間的問題,如果用mcu 自己去掃描當然也是可以,如選用專用 驅動掃描元件,會讓程式寫起來較輕鬆何樂不為呢,很早以前 有8279現在已停產了,還有一些小廠有在出貨,但因其介面是並列相當耗mcu的GPIO, 現在介紹一顆盛群(HOLTEK)HT16K33 SOP28 它能驅動8*16段LED ,也就是可以驅動16位七段顯示器, 可以有16階調整亮度,接3*13個 按鍵, IIC介面 MCU只需用2隻GPIO很方便的, 最重要是台廠的啦

有點聳動的標題, 現在的南韓真的是這樣嗎 ?

相信很多人都有51的學習板,應該都已經在 被遺忘的角落很久了吧! 這陣子 做了一片LQFP48轉DIP40的PCB 讓NUVOTON
CORTEX M0 ,轉成和DIP51 腳位完全相容,可以直接裝在 舊51學習板上, 如果舊51學習板上有Uart 燒寫成序的功能 ,
也可以用這功能來對 M052 (CORTEX M0) 進行程序燒寫, 當然 也可以由轉接板上預留的連接器用 J LINK 或 NU LINK
,進行DEBUG 或燒寫程序 , 是的 我的舊51學習板又重新被我拿出來用了  有圖有真相
 

笙泉有包一顆SOP8的51-- MG86E/L104 ,1T內核 4KB FLASH ROM 256BYTE RAM,  對習慣用51的人可以多一種選擇, 目前只支持ISP燒錄,沒辦法用UART UPdate , 這是遺憾啊! (stc 15f104 也是8腳包裝,可以用uart update的說)

現在笙泉新出的chip , 都必須用新的ice  才能用,舊的是下面4針 , 上方為新的6針 他是ice 和 icp 兩用

樣品入手 64PIN的腳距是0.4mm ,48pin腳距是0.5mm
