Francesco Ferrara commented on Bill Nesbitt's blog post AutoQuad ver 5"Bill, what is the f factor in the derivative component?
pid->dTerm_1 = (d * f) * (error - pid->dState);
pid->dState += f * (error - pid->dState)

Francesco Ferrara commented on Francesco Ferrara's blog post Ardupilot as OSD WITHOUT additional hardware (NO LM1881)"I'm near a new version, that use SPI port not USART, pin needed D11 MOSI, D6 D7 to use analog comparator (with only 2 resistor!!!).
D11 (PB3) is not used.
D6 (PD6) is "remove before flight"
D7 (PD7) is GPS power switch
How it is…"
Rana commented on Francesco Ferrara's blog post Ardupilot as OSD WITHOUT additional hardware (NO LM1881)"It is not a big deal, you can cut the tracks of two pin and with small wires solder them on required pins on the microcontroller or. You can modify modyfy the pcb of Openlog, it is freely available for download.
I have pasted the files here…"
Francesco Ferrara commented on Francesco Ferrara's blog post Ardupilot as OSD WITHOUT additional hardware (NO LM1881)"To use the analog comparator, PD6 PD7 (AIN0 AIN1) are needed, but are not avaiable on this implementation sorry."
Rana commented on Francesco Ferrara's blog post Ardupilot as OSD WITHOUT additional hardware (NO LM1881)"Yes, F. Ferrera, thats right !

BaroneOSD is a PAL video overlay impression WITHOUT additional hardware required (NO LM1881 Sync generator).
Use only 3 pin:
D1 (USART TX) used to pump pixel in the video connected with a 330Ohm resistor to D6
D6 (AIN0) Video in/out, connect here you camera or radio TX.
D7 (AIN1) 0.3V Voltage reference (you can use a partitor resistor)…
