Futaba SBUS - BMP280 variometer bug #105

Closed palomba01 closed 1 year ago

palomba01 commented 1 year ago

I'm trying to use the legacy arduino code with a BMP280 for altitude/vertical speed, on Frsky works great but on Futaba SBUS the vertical speed oscillates too much even when still and flying the values have the correct feeling but with exaggerated values, +30m/s on a real +1m/s thermal. vario

I am using MSRC (Regacy) on my FUTABA SBUS system. In my case, there is no abnormal change in data with BMP280. Please refer to the attached video. Also, how about changing the value of averaging in CONFIG.H of MSRC? It may be oversampling in BMP280.

Thanks for the reply, I've tried to increase the CONFIG_AVERAGING_ELEMENTS_VARIO up to 5 and the abnormal data still the same, also tried to reduce the refresh rate without sucess.

In the previous report, I used FUTABA's R3001SB (T-FHSS), but I tested it with your FASSTest receiver (R7106SB), and there was no abnormal data fluctuation. Why don't you check if there is no temperature change etc. with Arduino pro mini? Please refer to the video below.

I've tried to check this week but didn't work either, can you send me your config.h? Maybe I'm missing something

zxd00276 commented 1 year ago

Dear, I am attaching the requested config.h. I think it's data from your FUTABA T14SG's TELEMETRY Are you updating to the latest version of the software? Why don't you check if there is no problem with T14SG once? [config.zip] (https://github.com/dgatf/msrc/files/11024686/config.zip)
