RDA5807M + Arduino Pro Micro + SerialRadio Example = Random Freezing #14

Closed MatPeff closed 1 year ago

MatPeff commented 7 years ago

Hello, At the beginning thank you for this work , It's very interesting project and comprehensive solution to easy implement of SDR receivers. I have a problem like this : I connected typical RDA5807 module to Arduino Micro and have uploaded example from your library - SerialRadio. Everything looked good , i could give serial commands to the radio( like frequency change (fxxxxx) , seekUp , seekDown , volume +/- ) , i could receive RDS messages but after few minutes I lost communication with radio via serial. In other case i have connected a LCD with I2C converter and encoder to manually control of radio(change frq , vol etc...) . Frequency , and RDS was displayed properly , I could control radio by encoder but after few minutes everything froze again and I couldn't control radio by encoder. RDS refreshing was frozing too. I2C Addresses of LCD and RDA are different , I think that isn't a problem. In my custom implementation I turned off a serial communication. I have tried to comment parts of code with control encoder but It still isn't It and It did not help.

Below is my implementation of your code with LCD control :

Could you help me with this problem ? I would be very grateful for your help :) Best regards. Matthew.

@MatPeff, do you still have this freezing problem? Maybe you suffer to this arduino/Arduino#1476 issue in Wire library? Take a look at my wmarkow/arduino-hifi#3 where I describe my problems with a blocked I2C; maybe it will help you. At least you can use ArduinoCrashMonitor to find the place in the code which is responsible for freezing.
