[Closed,completed]conflict while Multi master access 1 slave EERAM (microchip 47C04)
I have finished the bit bang version of IIC driver for 47C04(microchip, EERAM). It took me so much time to try error. Now, it works well. Anyone works on Arduino can use it.

IIC is not so stable to communication. But for memory sharing, any other solution? SPI : too much pins to use. parallel port : never think of it :)

So you mean I should use bit bang instead of TWI hardware?

[Closed] Timer1 interrupts not in desired interval
These days I did some study, the codes posted before is not right, e.g.:   void IRsender::sendByTimer1(){     unsigned int tcnt1;        TIMSK1...

[Closed] Timer1 interrupts not in desired interval
I have posted it before (#6).   Thanks for your advice to use UART port, new direction for me.

[Closed] Timer1 interrupts not in desired interval
I setup a little test project, init in setup() and set value for TCNT1 and monitor it ,it works well.   So other codes affected the timer1. But what can do this?

[Closed] Timer1 interrupts not in desired interval
As the picture attached before, the first wave is too long.   I monitored the data last sunday , the result is unbelievable :)   I set the start value for TCNT1 in...

[Closed] Timer1 interrupts not in desired interval
You are right. Actually, I make copy after each modification (each day). When this bug raised, I thought about the design carefully, and decide to change the mode to timer...

Thank you very much to response :)   This afternoon, I found one library : timeone for ARDUINO. I studied it and got some advices. After changed the code ,the bug solved,...

The main reason is hardware : ARDUINO exist for so many years, and it has many boards to select with a free IDE. And it is so cheap.   I'm trying to develop a laser war DIY...
