#83454 - I2C already implemented. Responding to: ???'s previous message |
Hi Raghu,
Since you already have an I2C implemented and you are falling short of micro port pins. How about using PCF8591 4 channel ADC + DAC. It is 8 bit unipolar with max Analog Output +5V thus the polarity correction and amplifying twice may be separately done. PCF8591 has speed equal to your I2C speed bus thus when running at full speed 100KHz I2C you can fetch 11,000 sample per second speed. Regards, Prahlad Purohit |
