Hello :)
I have a question regarding controlling Motors using Pygame
so , i bought the Jetson nano 2GB version at start, and it worked well with the same setup → FeatherWing dc motor controller and pygame to control the motors, it just works fine. So then I wanted to upgrade to the full 4G version so I just got it. The thing is that with the same setup, installing the same version of pygame, same libraries to control the DC motors and so on. It turns out that when I want to throttle up it does but in steps and not continuously as the 2G version, for some reason the 4G version needs something else. Please Help Me to identify the error please.
Here is the code I’m using
import pygame
import cv2
import time
import board
from adafruit_motorkit import MotorKit
print(cv2.version)
#—Motor Setings i2c
kit = MotorKit(i2c=board.I2C())
#—pygame focus
screen = pygame.display.set_mode((240,160))
#valor de velocidad
v = 0
try:
while True:
#------------ControlDriver----------
for event in pygame.event.get():
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_RIGHT:
kit.motor1.throttle = -v
kit.motor2.throttle = v
kit.motor3.throttle = v
kit.motor4.throttle = -v
print(‘Right’)
elif event.key == pygame.K_LEFT:
kit.motor1.throttle = v
kit.motor2.throttle = -v
kit.motor3.throttle = -v
kit.motor4.throttle = v
print(‘Left’)
elif event.key == pygame.K_DOWN:
kit.motor1.throttle = -v
kit.motor2.throttle = -v
kit.motor3.throttle = -v
kit.motor4.throttle = -v
print(‘Down’)
elif event.key == pygame.K_UP:
kit.motor1.throttle = v
kit.motor2.throttle = v
kit.motor3.throttle = v
kit.motor4.throttle = v
print (‘Up’)
elif event.key == pygame.K_q:
pygame.quit()
elif event.key == pygame.K_1:
v = 0.7
elif event.key == pygame.K_2:
v = 1
elif event.type == pygame.KEYUP:
kit.motor1.throttle = 0
kit.motor2.throttle = 0
kit.motor3.throttle = 0
kit.motor4.throttle = 0
print(‘Pakal-rover V5’)
#---------------------------------------
finally:
kit.motor1.throttle=0
kit.motor2.throttle=0
kit.motor3.throttle=0
kit.motor4.throttle=0

I´ve test it using a 2G version and it works just fine, it goes without any interruption but with the 4G version I get this interruptions when throttled
