question about CapSense(I2C failed)
I am a newer about Psoc4, Yesterday , I attened cypress seminar at hangzhou , and I had not pass the third experiment about CapSense with your PSOC4 Pioneer Kit.
The aim of this experiment is make developers to familiar with the CapSense module, and the experiment seems very simple , but I have not past .
The experiment only have one componment --- CapSense , I add a CapSense to the project, and add a linearSlider to the module , then enable tune helper ,set the I2C data Rate to 100kbps, and set I2C address to 8.
Then configure the IO port .
Last , add source code to main.c
// CapSense_1_EnableSensor(); //Not sure where to put this??
/* Place your initialization/startup code here (e.g. MyInst_Start()) */
/* CyGlobalIntEnable; */ /* Uncomment this line to enable global interrupts. */
/* Place your application code here. */
But when I run the application , open laucher panel . Configuration the I2C , and start , It reports failed !!!!!
The error information is "Read operation" failed ! Check I2C bus connection.
can sb tell me why?
