    Manually Drive SDA and SCL, I2C PSOC 4200

    user_432248552

      Hi, so here goes.... I have a sensor that i  talk to over I2C everything seems to be setup correctly as I'm able to query the device and get valid data over I2C, what i try to do next is put my device to sleep and then wake it up over I2C by utilizing the 

         

      moduleName_sda_Write(uint8 byte)

         

      moduleName_scl_write(uint8 byte)

         

      as the spec requires SDA be held LOW for a certain amount of time. 

         

      The problem i run into is it doesn't seem that my sda_write() is ever happening as im not seeing them on my logic analyzer and the device never wakens, anyone have any hints as to where  to look next?
