I just installed ServoBlaster on Bullseye and it just does not work. This is what I get doing ./servod
pi@raspberrypi:~/PiBits/ServoBlaster/user $ sudo ./servod
Board model: 3B (mem_flag 0x04)
GPIO configuration: P1 (40 pins)
Using hardware: PWM
Using DMA channel: 14
Idle timeout: Disabled
Number of servos: 8
Servo cycle time: 20000us
Pulse increment step size: 10us
Minimum width value: 50 (500us)
Maximum width value: 250 (2500us)
Output levels: Normal
Using P1 pins: 7,11,12,13,15,16,18,22
Servo mapping:
0 on P1-7 GPIO-4
1 on P1-11 GPIO-17
2 on P1-12 GPIO-18
3 on P1-13 GPIO-27
4 on P1-15 GPIO-22
5 on P1-16 GPIO-23
6 on P1-18 GPIO-24
7 on P1-22 GPIO-25
pi@raspberrypi:~/PiBits/ServoBlaster/user $
And then I tried the following commands :
pi@raspberrypi:~/PiBits/ServoBlaster/user $ echo 0=150 > /dev/servoblaster
pi@raspberrypi:~/PiBits/ServoBlaster/user $ echo 0=110 > /dev/servoblaster
The brushless motor does not start, but I have just a beep tone showing that something happens on PI-7 GPIO-4.
Remark : I have installed ( 3 years ago) and used ServoBlaster on the same hardware with Stretch : It still works perfectly .
So my question is : is Bullseye compatible with ServoBlaster ? or any known problem with the current version ?
