Cc2530 chip of temperature and humidity sensor experiment, finally receive less than data in a serial debugging assistants, after open the hexadecimal display always shows 00, have great god know why

CodePudding user response:

Give too much information, don't know what your problem is a serial port communication code or 2530 drive function, can be fixed data into the master microcontroller send buffer, the first to determine the serial communication is normal, then you can pursue back to 2530 data errors, if the data is 2530 is 0000, so should be device initialization not ready,

CodePudding user response:

The uart baud rate is set to? Like cc2530 examples are made of 115200 baud rate

CodePudding user response:

The problem decomposition,

The other functions first note, only keep a serial port output function, can add statements provide data,

If a serial port function as expected, no problem, will have a further check other functions is what is going wrong, did not provide data to a serial port transmission function,

CodePudding user response:

I can give you a contact, I do you are stuck in the here now

CodePudding user response:

When we do experiments that a53 board didn't appear the information of temperature
Is the information of 615.13 strange no humidity
