lpc2378 timer

hi everybody ,

i wanted to know how to put true values into match registers of a timer
for exemple T0MR0 or T0MR1 ,

for exemple i want to generate an interrupt after 20 ms and the period (T0MR0 = 60ms)
what would i put into T0MR0 and T0MR1 ???

thank you in advance

no answer ???

The lpc2378 is not a device used by many here, so you are unlikely to get a detailed reply unless
DavesGarage visits.

I found this thread that seems to cover the question you asked.
It is not for exactly the same device but should be close enough.

thank you for the answer

Thanks..
hope it helped.

simplest way is..

TMR0 = TIME_MS * TMRCLOCK/1000 - 1; // this will generate almost exact delay as you want. try it. this applies to all.. timers.

in above equation,
TIME_MS = delay in miliseconds you want e.g. 20 for 20ms
TMRCLOCK = clock in Hz you set during startup for that timer e.g. if 12Mhz then 12000000

Hope this will help you

Okay.. or Ajay of course

@Phil hehe.... thanks

After ARM7, I moved on to ARM9 now Armada100 Family... Linux is nice, still learning.

Ha! You guys crack me up... I too have moved on from my brief experimenting with the LPC2478, and am now deeply into the LPC1788 Cortex M3 processor...

I would recommend downloading the examples from the NXP website. They go over every peripheral the device has to offer, complete with working code examples. You can find them at NXP.COM - check it out.

I agree with dave they have good examples..
