Manually Drive SDA and SCL, I2C PSOC 4200
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
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?
