i have implemented software I2C with
when even the lowly sub $1 LPCs have hardware IIC Erik the reason i meantioned that.. is because, Oleg said:
Atmel Smart Card Reader ICs Devices are listed here: http://www.atmel.com/dyn/produ...ily_id=650 Sure, AT8xC5121..C5123 and C5127 has no built-in I2C. But use software I2C as Jez Smith already said. There is nothing hard with it, do search over the forum. Regards, Oleg so i thought if the Atmel IC is available with on chip smart card interface and no IIC so implementing I2C in software will be a great idea. so i gave the DIRECT LINK to the file. if you have a problem with it. please dont post, because your sugession of a $1 LPC is not the solution to this mattar. regards, ajay bhargav admin http://rickeyworld.info |
