I have got an AT89S52 and a USB to TTL converter. Can anyone help me with programming the AT89S52 with the TTL. I downloaded a lot of IDEs and nothing seem to upload the code to MCU, is there a specific IDE I could use . Some IDEs doesn’t even have option dor 89s52, and do I need to connect the MCU to clocksignal , Rst, ALE pins to be able to program serially. I hadbeeen on this do two days now and no improvement yet. It will be of great help of anyone could guide here. Thanks in advance
