Hi, the Crius Pro is Fitted with an Atmega 2560 as is the Flyduino Mega A0 is the correct Voltage Pin for that board -> (m) you wont need to change the pin in the code as the Arduino MEGA as Target-Board defines this pin in the multiwii software you should see the correct voltage when you connect th...

Re: Rushduino OSD - Multiwii based open software osd

Hi rortega, best way to do this with minimOSD is to use the voltage monitor of multiwii, use a voltage divider konsisting of 2 resistrors like here m BTW for more than 3S battery we can different divider because 51k/33k can measure only up to 12.5V battery voltage. With 100k/33k we can monitor up to...

Hi, do not need to connect reset pin 10 of arduino on Minim OSD to max7456, leave it as is. The two jumpers on back of minim osd board are only for 5V supply coming from FC (on same serial port), in this case you do not supply with 12V from Tx/cam 3 pin connectors! To load char map, you need a spec...
