i´m having trouble arduino uno , 16-bit shift register made out of 2 cd4094´s. the program appears working, leds connected on outputs of shift registers nothing. doing wrong ? code: [select] #include <avr/pgmspace.h> #include <spi.h> const int latchpin = 10; //pin connected str(pin 1) of hef4094 //clock = 13, mosi = 11 const int eprom[12] = {0x01, 0x02, 0x04, 0x08, 0x10, 0x20, 0x40, 0x80, 0x100, 0x200, 0x400, 0x800}; int address = 0; byte = 0; void setup() { // put setup code here, run once: pinmode(latchpin, output); digitalwrite(latchpin, low); spi.begintransaction(spisettings(500000, lsbfirst, spi_mode0)); // initialize spi serial.begin(9600); } void loop() { // put main code here, run repeatedly: address = eprom[i]; serial.print(i); serial.print(" "); serial.println(address, hex); serial.println(" "); addressout(address % 256, address / 256); ...
