Around four years ago I started a thread called “RobotC programming tips”. I’ve decided to start another called “RobotC - Bad programming habits” as I’ve recently seen multiple examples of the same bad programming techniques being used and it seems that we (the forum) should try and address these s…

Functions are your friends Post #1 contains the worst programming bad habit I see, repeating the same lines of code over and over again when they should be placed into a function. For example motor DriveWheel_LF ] = 127; motor DriveWheel_LB ] = 127; motor DriveWheel_RF ] = 12…

Tasks are not functions A function (or subroutine as it’s sometimes called) is a reusable section of software. Some functions are part of the ROBOTC library, for example, wait1Msec is a function that halts the program flow for the specified number of milliseconds. Some functions are ones that you…

Stop your motors jittering It seems like almost everyday we get a new question about motors that are jittering on the robot. The cause is setting the motor to multiple different values within the driver control infinite loop. Typical code may look like this. #pragma config(Motor, port1, …

Keep your code well formatted What’s wrong with this program? #pragma config(Motor, port1, MotorA, tmotorVex393_HBridge, openLoop) //*!!Code automatically generated by 'ROBOTC' configuration wizard !!*// task main(){int MotorA_Value;while(1){MotorA_Value=0;if(vexRT…

Inspector Gadget: Sophomore year, I wrote a very complex code in RobotC that i decided (for some dumb reason) should be exactly 100 lines. Sometimes I think the students participating in VEX would be good at this competition. The International Obfuscated C Code Contest

@jpearman I was just wondering about a claw, should positive motor values be closing the claw or opening it??

I don’t think it really matters with a claw, the last time I programmed a clawbot I set encoder position 0 as closed and the open position ended up at around 500 counts. That code is at the end of this thread.
