big fluctuations in the received values

[HNeumeier]

i have tried the following example
#include <sbus.h>
// used pins
#define SBUS_PIN 13 // D3
SBUS sbus;
void setup() {
Serial.begin(115200);
sbus.begin(SBUS_PIN, sbusBlocking);
}

void loop() {

if (!sbus.waitFrame()) {
Serial.println("Timeout!");
} else {
Serial.println(sbus.getChannel(3));
}
if (sbus.signalLossActive())
Serial.print("SIGNAL_LOSS ");
if (sbus.failsafeActive())
Serial.print("FAILSAFE");
}

and the values i get back looks like this, why i have such big fluctuations, i have done nothing on the sender, can you help me.

Hi
I see the same, please someone fix this. It's the only lib I found, that does need an inverter - maybe that's why it does not work.

Same problem here. Blocking or non blocking usage. Without a hardware UART's buffer, combined with a hardware inverter in front of it you will always miss too many frames to have a stable reading.
