Hi community,
I am using Atheros AR9331 + OpenWRT Chaos Calmer 15.05 on a commercial
product.
I've used I2C on many projects, all with dedicated I2C controllers. I've
never used GPIOs to simulate I2C on Linux.
I may be wrong, I am tending to think that there is no way to generate
good I2C waveforms by using 2 GPIOs (SCL/SDA), except that we disable
all interrupts and maybe using high precision timer when outputing SCL/SDA?
Is "using gpio to simulate I2C bus" robust on AR9331?
Thanks.
Xuebing Wang
