NANO V3
Hy, it uses fine on Mega, on UNO but seems stucked on NANO V3 (ATmega328p), is it not possible ? I have add Softawre serial to be able to readsome debugs which work on UNO but no possibility to see anything on Arduino Nano. On a program I am making for rc model lighting using SBUS from channel 9, I get running on UNO but not on Nano. Nothing happens. I am trying since a week now and a good advice if NANO yes or no would be nice. Otherwise it is a perfect library. Thanks for reply, André
Doesn't work reliably on Pro Mini as well. Initializes once in 50 resets.
Found a workaround which seems to work reliably on Pro Mini: It merely reboots Arduino until it starts capturing valid packets. Surprisingly enough this code works pretty good and fast.
#define SBUS_WARM_UP_TIME_MS 100
void(* resetArduino) (void) = 0; //declare reset function at address 0
void setup() {
sbus.begin(false);
uint32_t ms = millis();
while(millis() - ms < SBUS_WARM_UP_TIME_MS) {
sbus.process();
}
if (sbus.getGoodFrames() == 0) {
resetArduino();
}
...
How do you get it to work on nano? @voroshkov did it not work at all for you at first ? when you used pro mini
@eskaflon, yes - didn't work on Pro Mini until I implemented the "hack" described above. Tried 2 ProMinis with the same result. At the same time didn't notice an issue on Uno board. That's weird because both have ATMega328p chip, 16MHz oscillator and 5V voltage
@voroshkov Weird how it doesnt work on these boards, thanks for the hack. Is this how you used it ?
#include <SBUS.h>
#define SBUS_WARM_UP_TIME_MS 100
SBUS sbus(Serial);
void(* resetArduino) (void) = 0; //declare reset function at address 0
void setup()
{
sbus.begin(false);
uint32_t ms = millis();
while(millis() - ms < SBUS_WARM_UP_TIME_MS) {
sbus.process();
}
if (sbus.getGoodFrames() == 0) {
resetArduino();
}
sbus.begin();
Serial.begin(115200);
Serial.println("SBUS Status");
}
// this is timer2, which triggers ever 1ms and processes the incoming SBUS datastream
ISR(TIMER2_COMPA_vect)
{
sbus.process();
}
...
@eskaflon, no. On proMini you cannot use sbus & Serial, because Serial is used for sbus. Not sure about timer ISR - didn't try that.
My code is as follows:
...
void setup() {
sbus.begin(false);
uint32_t ms = millis();
while(millis() - ms < SBUS_WARM_UP_TIME_MS) {
sbus.process();
}
if (sbus.getGoodFrames() == 0) {
resetArduino();
}
// also setup pins and other stuff as usual...
...
}
void loop() {
sbus.process();
...
// and the loop should not be long to avoid sbus losing packets
}
