Code help

Postby Folny82 » Wed Feb 07, 2018 2:01 am

Hello friends

Can anyone advise me how to edit this sketch to work with ESP32 in advance thanks for your reply.

https://github.com/dc42/arduino/blob/ma ... tector.ino

Problem is with this frequent code

ISR(TIMER1_OVF_vect)
{
++ticks;
uint8_t ctr = TCNT0;
int16_t val = (int16_t)(uint16_t)ADCH; // only need to read most significant 8 bits
if (ctr != ((lastctr + 1) & 7))
{
++misses;
}
lastctr = ctr;
int16_t *p = &bins[ctr & 3];
if (ctr < 4)
{
*p += (val);
if (*p > 15000) *p = 15000;
}
else
{
*p -= val;
if (*p < -15000) p = -15000;
}
if (ctr == 7)
{
++numSamples;
if (numSamples == numSamplesToAverage)
{
numSamples = 0;
if (!sampleReady) // if previous sample has been consumed
{
memcpy((void)averages, bins, sizeof(averages));
sampleReady = true;
}
memset(bins, 0, sizeof(bins));
}
}
}

You will increase your chance of getting help if you describe what you have tried, and what you have seen.
Does it compile cleanly? If not, what error message do you see?
Does it run, but not correctly?
