| Jul 16, 2013 at 12:26 | comment | added | Santosh | oh wow! You can program both the 89s52 and c2051! So I will have to load the code in C2051 such that it passes the code to 89s52. Does it mean that like 89s52, I will have to initialize the c2051 in serial mode, then make it such that whatever code it gets in one pin is sent to 89s52? | |

| Jul 15, 2013 at 15:19 | comment | added | Santosh | Yes thats what I was asking. Today I asked the electronic store guy,he said the 89s52 need to have bootloader inside it to program it, and I have seen many people using AT89c2051 along with max 232 when programing 89sXX . SO I came to conclusion that 89c2051 contains the bootloader, and it transfers the code to 89s52 serially....correct me if I am wrong...I am very confused... | |
| Jul 15, 2013 at 14:46 | comment | added | JIm Dearden | @HS Yes - if you have a programmer for it. Most processors have both serial and parallel programming modes. Without them you wouldn't be able to write/store your own programs - it would be totally useless if it didn't. Some are One Time Programmable (OTP) but most allow you to reprogram many times. The large, more recent controllers usually have a USB style bootloader. The internal program tells it how to respond to the external programming signals and can directly connect with your computer using a standard USB port. Unfortunately the 89s52 isn't one of them. | |
| Jul 15, 2013 at 14:00 | comment | added | Santosh | It means the AT89s52 can be programmed out of the box? I mean just like those phillips 89v51, which contains bootloader code?The 89s52 also contains bootloader code too? | |
