hi
ı want to flashing 160 led. ı will use pic + shift register + 160 led and pc. detail information can be seen on image.
firstly ı have 20 kb data. this data will be transfered to the pic and pic will be stored data to the program memory. then every 20 ms pic send 160 bit data to the shift register. after 20 ms pic send data to shift register that all led must be turn off with a 20 ms. so that first 20 ms some led will be turned on and second 20 ms all led will be turned off. so first mini cycle will be finised. second mini cycle will be started and 160 bit data sended again and specific leds will be flashing.
second option's difference is the where stored data. the data will be stored to the SD card or eeprom ICs. then pic read data from these memory card and stored to the data memory not program memory.
which option can ı use? or is there any another option to flashing 160 led every 40 ms? What is your opinion??
thanks a lot for your response...
