Dear all,
I wanna ask how I can synchronize the SCL rate by software or hardware. I've manipulated my coding many ways -> (the delay) and the hardware either -> change the pull up R. But I've only could raise my clock rate up to 40KHz. I wanna get 100KHz clock rate. Is there any ideas??
Do I need to post my source code or schematic for u??
There are some intresting facts on clock synchronization and speed issues in:
"I2C (Inter-Integrated Circuit) Bus Technical Overview and Frequently Asked Questions (FAQ)" https://www.esacademy.com/faq/i2c/index.htm
Maybe some of these hints will be helpful in solving your I2C bus speed problem ..
Thx IanP for u're help.
But I still can't increase my SCL rate. I've modify hardware like the article said, but it can only help increase my rise time.
Could u give some references again I'm still confused?!
