 | | Swan scheduling bug?
|
| I'm starting to use the swan firmware and I'm having a problem with the scheduling. It seems like a task with a long wait does not yield properly to other tasks. Here the NQC code sample: task taska() { WaitMS(150); AddToDatalog(9900); } task main() (...) (19 years ago, 22-Sep-05, to lugnet.robotics.rcx)

| (...) Here's a code byte from my LegWay code. ---- int MotorSpeedArray[32] = {1,3,2,0}; // Speeds // ... later in the program... if (sys_time>CheckTime) // check system timer - is it time to check sensors again? { L1 = ReadSensor(SENSOR_1); L3 = (...)

| Hi Steve, As I'm quite new to BrickOS and to C programming, I'm sorry I'm not sure I understood what you meant, neither how you do this : (...) - Do you check the sensor at a higher rate, and only send a command to the motor at 1kHz ? - How do you (...)

| | | | | position servoing under BrickOS
|
| Thanks to your advices, Dick, Matt, and Steve, I've been very happy to solve my time sampling problems, installing BrickOS, which runs the rcx fast enough to get a proper position servoing (using rotation or light sensor, and a PID controller). I (...) (19 years ago, 20-Sep-05, to lugnet.robotics.rcx)
