#181375 - problem about STC 8051 |
Hello all
I got the STC11F08XE chips and tool from STC 51 a few days before. Our project was designed by Atmel's 8051. I download the hex file into STC11F08XE without any modification, then it works! But not that good..the blinking of LED shows that the speed is much faster than before, and the Read/Write of 24C16 doesn't work properly. Checking by osciscope and found the frequency of the I2C is toooooo high for 24C16. I read the datasheet and found there's a register to set the timer in fast/slow mode. The clock is devided by 12 in slow mode. But that's only works for timer, make no sense for other code. It seems that I have to rewrite some of the codes. Is there another better way to solve this problem? a good news is that we don't need stand alone eeprom any more. The mcu has it on-chip. Ray |

| Looks to me as though you ought to study the datasheet | 01/01/70 00:00 | |

Yes, that's what it appears to be! | 01/01/70 00:00 |
