|Subject:||[Paparazzi-devel] PPM input and trigger_ext module|
|Date:||Fri, 19 Sep 2014 20:07:00 -0300|
Today i finished the gasoline meter module.
It work using TRIGGER_ISR
I configured it do use capture channel 0 and it work fine if i choose radio as datalink.
When i configure the radio to ppm mine module stop do count pulses.
To solve it i changed the line
T0CCR = TRIGGER_CRR | TRIGGER_CRI;
T0CCR |= TRIGGER_CRR | TRIGGER_CRI;
Looking at ppm_arch.c i see that ppm not use |= when configuring T0CCR register.
I think the correct is to use
T0CCR |= PPM_CCR_CRR | PPM_CCR_CRI;
not T0CCR = PPM_CCR_CRR | PPM_CCR_CRI;
i am right ?
another question, how i do to know what capture channels are used in lpc firmware ?
