I grabbed the db9 image link. The only pins needed is pin2 and pin3. You can short them together with a small screw driver if you are careful.
well i did the “ver test” - it recives 16 bytes with the pins connected by a screw. When i connectr the robot i recieve 0.
what is my next step? I mean - should i connect the battery? or switch it on? to install the programs? or is it enough to use the com cable?
Also, when i start the robot without a cable but with a battery - it starts doing smth. But when swithced and with a cable it doesnt link to the computer.
fine, it seems that it is me who is stupid after all))… i downloaded the instructions from a hitec website - and there, they say to first attach the battery, then swith it on and ONLY THEN download the program. So that’s what i am going to do at home in 6 hours…
now i have another problem - should the servos make sounds like “piiiiiiiiiiiiiiiiiiiiiiiii” ?
Servos typically hum under continuous load.
Digital servos usually hum at a higher frequency than analog servos.
Be aware of servos getting hot, too hot to touch is usually not healthy for the servos.
Sometimes when servos get corrupted signals and such, they will fully rotate in one direction until they hit the gear stop and stall, making a buzzing sound. Running a servo in a stalled condition is usually not good for the servo.
I thought of that too but somehow was under the impression he was using an ssc-32 which should minimize the chance of that.
Upon reviewing the thread I don’t see that use of the ssc-32 was established so… good catch.
