Hi, sorry for my late reply. I used this Schmitt trigger: https://www.rcgroups.com/forums/show....php?t=1006124 The "on the fly" setup was working fine, currently I test my first PCBs, capable of measuring current, voltage (up to 6s) and RPM by measuring one phase of a brushless motor. Aft...

Hi, I finished the measurements and found a factor of 12 between actual RPM and values shown on HOTT (using the /10 factor as mentioned by mstrens). I know you have to devide the poles by 2 so I think the formula TxHottData.gamMsg.rpm = RpmValue * 6 /(#poles/2) should do the job. The values I receiv...

Hi mstrens, thanks for the quick reply. I just gave it a try and in deed the value displayed on the transmitter changed with the settings I changed as you suggested. Unfortunately it is dark outside and I can not check the displayed value with my optical RPM measurement tool. I'll keep you updated. ...

Hi, I just build an oXs for brushless RPM, current and voltage measurment on a ProMini. Installation went smooth I can also read the RPM on the transmitter. Unfortunately, I can not access the telemetry setup menu on my transmitter which should be available after the receiver menu if general is sele...
