#81776 - Things to check Responding to: ???'s previous message |
Hello
The C compilers I know add a startup code to your application, that must be configured correctly. Check project settings of the compiler IDE. Or, if available, load the code it into a simulator and inspect the code of this 'little' application. The Atmel AT89c51 is a controller with FLASH memory on chip. Is the FLASH programmed correctly? Is, by accident, the EA pin low, accessing external code memory instead of onchip FLASH, which might not be available, that depends on your hardware configuration. Best regards, J. Christoph |
