 19 Sep 2003 18:22 Counting high speed pulstrain with 80c51 microcontroller |
|

Hello ,
i have to count an amount of pulses during a certain time .
I know that i can use a counter for this but the problem is that the pulstrain that i have to count has a frequenty of 10 Mhz .
With a standard 8051 microcontroller i can only count 1/24 of the oscilator frequency. This means a 240 Mhz clock as a clock frequency this is of course to high .
I was looking on the website of cygnal and found a microcontroller that should be able to do the task (C8051F12x family) . However this is a lot of overkill cause i only need two counters . (i have to do this for two different signals)
Is there anyone that have experience witch such thing or can give me other types of microcontrollers (8051 family)
Prescaling is not allowed , the measurment must be accurate.
Kind regards,
Gandalf
