Changing COM baud rate
Awesome astrowork!
Actually I have three questions:
- Is it possible to increase COM baud rate up to 57600, meaning, would that possibly affect avrdude?
- Is it possible to configure different microstepping configuration for per axis? I.e RA 1/32 and DEC 1/16
- Is there a way to switch from North to South sidereal tracking direction without reflashing configuration (in driver? Or maybe hardware 2-way switch...)
- You can cheat If you double or half the like motor gear ratios
- Why do you want to change direction when You can do this from EQMOD
- I don't use EQMOD nor ASCOM. I use this with INDI server on Raspberry PI, Joystick and android App (IPARCOS). Recently I discovered that I can connect Arduino MEGA via UART port on RPi and TTL logic level converter (because RPi works with +3.3V). This way I don't need udev, or USB and I can connect multiple AstroEQ devices to single RPi INDI server and I can use INDI via serial pins or ASCOM via USB with double hardware switch. And everything works flawlessly!
This is ASCOM independent. And I also have raspi so: 2. you have to change in the firmware gear ratio(example): RA 2, DEC 4 3. Find some research just a little help -15,041067
Why do you want to increase the baud rate? Doing so won't make the AstroEQ run any faster. In practice it will likely result in lower reliability as the command processing loop may not be able to keep up, and hence start losing characters.
The firmware for the AstroEQ is already push the limit of what an AVR can do in terms of multi-tasking (controlling two motors, while also interfacing with the PC).
I need to test that on my own. So far i found 38400 with smaller timer and bigger buffer noticably more responsive. May be due to my setup which include additional modules like I²C display (for encoder values) and HC-05. I believe there are more framing errors on 9800
