I have a schematic of 8051 interfacing with 6264 below, but I think it's problem. Could anyone to tell me what the problem with my schematic is. **broken link removed**
Thank you !
If program memory resides in the MCU (version with built-in ROM, EProm, OTP or Flash) and RAM is properly addressed using A13, A14 and A15 then I can’t see any hardware issues ..
What’s your concern?
First, make the delay time about 1ms ..
Then, keep in mind that the current to segments has only 25% duty ratio and it is limited by resistors ..
You selected 10k and that value is much, much to big .. try something like 100ohms ..
