Hi,
sorry I haven't replied too quickly, my computer broke down...anyway, I'm making a metronome, and I want, every few beeps, to have a higher frequency beep. This counter sets the number of low beeps between each high beep. eg if H=high and L=low, pattern when counter is set to 0 is LLLLL, =1, HLHLHLHL, =2, HLLHLLHLL and so on. THe chip above will not (I don't think?) allow both the counter and the bit where you set the number on the left to be incremented. The aim of integrating this chip into the circuit is to actually reduce the number of ICs in the circuit overall, and if I use the CD4522 as suggested by Sebi, I will need a seperate BCD counter to control P inputs P0-3. I was just wondering if there was another, similar chip, where A clock input had been integrated to increment P0-3 by 1 whenever it went high.
