    hello everyone,could you tell me how to program the H8/3022F

    i want to program the H8/3022F(HD64F3022F),use a simplest way. i read some datasheet on this project,but i don't understand clear. how to use the SCI to program it?I want to program it like use a ISP cable or some other simple programer.and how to have a cable or a simple programer? who can...

    LCD 4-bits Interface to AT89C51

    anupam dubey aims interactive this code is using in the LCM driver by 44780 ,if your LCD is not driver by HD44780,then you should modify some code,refer to the datasheet of your LCM. the Initial code is very important,and maybe it is different if your different typr LCD.

    how to let MCU excute the code from main(),in every wake??

    Hello everyone,pls give me a hand! Now i'm using a PIC16F914,i want it to woke like that,but i don't know how to write the code by HI-PICC. i want the cpu to do that: cpu power up --> initial IO-->sleep ,just the INT0 can wake up the CPU. i want the every wake up,the CPU can excute the...

    Moving message display on LCD HD44780

    check the HT44780 datasheet.set the "s/c" bit when wtire the "Cursor or display shift" instruction, and the "I/D" of the "entry mode set" instruction,you will get something! Good lucky!

    dspic30f4013 UART ,Pls give me a hand!

    xtfreq dear mehdi_an: Thank you very much! Now i have find the error , the code is right.the bug is in my PCB. I confuse the line2 and line4 of the DB9.So MCU can receive data from PC use the lien 3,but could sent data.the data be transmite in the line4,so the PC cann't capture it ...
