    I2C implemented by GPIO

    gpio i2c driver Chose two I/O pins for SDA and SCL and connect them to I2C device(slave mode) directly. See, it works. The C code for 8051:

    Why the interrupts in 8051 slow down the code?

    8051 Interrupt I think the interrupt response time is related with the MCU clock and the data transmit frequency of keyboard.I interfaced 8051 to a keyboard in a project before. The response time is ok.

    Which PCB tool will be the best choice to beginner?

    The software doesn't design a board, the operator does. Take a look here:

    real time clock interfacing with 8051?

    8051 as rtc PCF8583 is another good choice.It is easy to use and you can get more than 240 bytes extra SRAM for CPU. Look at the C code:

    JTAG Tools software package

    It's turely a very nice baby for the ARM guys. You can use it under SDT2.5 ,SDT2.51,ADS1.1andADS1.2 with the simple jtag cable. It is developed by Armjtag, and It's free.Thank Armjtag very much! Try it soon! Looks there: https://armjtag.27h.com/
