Need more Flash for Raspberry Pi Pico? Dislike the outdated Micro USB connector? All their problems are solved by our RP2040-Plus now.
As same as Raspberry Pi Pico, it incorporates the RP2040 microcontroller, with a dual-core Arm Cortex M0+ processor running up to 133 MHz, and 26x multi-function GPIO pins.
What's different, it features an onboard 4MB Flash, USB-C connector, recharge header, and higher current DC-DC chip.
RP2040-Plus uses the same RP2040 chip as the Raspberry Pi Pico, and it is compatible with the Raspberry Pi Pico, in this case, most of the accessories and codes can be used with the RP2040-LCD-0.96 as well.
Please follow the guides of Raspberry Pi to install and set up Pico for the Pico.
For easy use, we recommend you use the Thonny tool.
Connect the boards as in the picture below. Connect the Pico to Raspberry Pi or PC. Open the Lesson-5 External LED example with Thonny. Run the example, and you will find that the red LED is flahsing.
led_external = machine.Pin(15, machine.Pin.OUT) #Set GP15 to output Mode while True: led_external.toggle() #Toggle the LED every 5 seconds. utime.sleep(5)
Connect the boards as in the picture below. Connect the Pico to Raspberry Pi or PC. Open the Lesson-9 Traffic-Light-System example by Thonny, run the codes and test the traffic light, the buzzer sounds when you press the button.
def button_reader_thread(): #Check if the button is pressed global button_pressed while True: if button.value() == 1: button_pressed = True _thread.start_new_thread(button_reader_thread, ()) #Start a new thread to monitor the stats of button while True: if button_pressed == True: #If the button is pressed, turn on the LED and let the buzzer work. led_red.value(1) for i in range(10): buzzer.value(1) utime.sleep(0.2) buzzer.value(0) utime.sleep(0.2) global button_pressed button_pressed = False led_red.value(1) utime.sleep(5) led_amber.value(1) utime.sleep(2) led_red.value(0) led_amber.value(0) led_green.value(1) utime.sleep(5) led_green.value(0) led_amber.value(1) utime.sleep(5) led_amber.value(0)
Connect the boards as in the picture below. Connect the Pico to Raspberry Pi or PC. Open the Lesson-14 Burglar Alarm LED Buzzer examples by Thonny.The LED lights on if an object is moving around the Passive infrared sensor and the buzzer will indicate.
def pir_handler(pin): #Interrupt process function print("ALARM! Motion detected!") for i in range(50): led.toggle() buzzer.toggle() utime.sleep_ms(100) sensor_pir.irq(trigger=machine.Pin.IRQ_RISING, handler=pir_handler)#Enable the Interrupt, the interrupt function is called when motions is detected. while True: #Toggle LED every 5s led.toggle() utime.sleep(5)
Connect the boards as in the picture below. Connect the Pico to Raspberry Pi or PC. Open the Lesson-16 Potentiometer example by Thonny, you can adjust the potentiometer and check if the voltage printed to the Sheel window are changing as well.
potentiometer = machine.ADC(26) #Set the GP26 pin as analog input conversion_factor = 3.3 / (65535) while True: voltage = potentiometer.read_u16() * conversion_factor #Convert the sampled data to voltage value print(voltage) #Print the voltage data, it chanaged according to the sliding rheostat. utime.sleep(2)
Connect the boards as in the picture below. Connect the Pico to Raspberry Pi or PC. Open the WS2812_RGB_LED.py file of Lesson-25 WS2812 example by Thonny, the LEDs light in Blue, Red, Green, and White.
#This code uses the state machine mechanism. The following code is a decorator where we can initialize the hardware, set the pin level, etc. #label("bitloop") We can define some tags in our code so that we can jump to them. #jmp(not_x,"do_zero") If x=0, we jumpt to do_zero. #nop() .set(0) [T2 - 1] The code jumpt to here if x = 0. @asm_pio(sideset_init=PIO.OUT_LOW, out_shiftdir=PIO.SHIFT_LEFT, autopull=True, pull_thresh=24) def ws2812(): T1 = 2 T2 = 5 T3 = 1 label("bitloop") out(x, 1) .side(0) [T3 - 1] jmp(not_x, "do_zero") .side(1) [T1 - 1] jmp("bitloop") .side(1) [T2 - 1] label("do_zero") nop() .side(0) [T2 - 1]
# Create the StateMachine with the ws2812 program, outputting on Pin(22). sm = StateMachine(0, ws2812, freq=8000000, sideset_base=Pin(0)) #Create the stats machine # Start the StateMachine, it will wait for data on its FIFO. sm.active(1) #Start the stats machine # Display a pattern on the LEDs via an array of LED RGB values. ar = array.array("I", [0 for _ in range(NUM_LEDS)]) print(ar) print("blue") for j in range(0, 255): for i in range(NUM_LEDS): ar[i] = j sm.put(ar,8) #put() is put the data to output FIFO of the stats machine time.sleep_ms(5)
Connect the boards as in the picture below. Connect the Pico to Raspberry Pi or PC. Open the Lesson-21 LCD1602 I2C example by Thonny, you need to first save the RGB1602.py to Pico and then run the Choose_Color.py file. The LCD will change color every 5s. If you run the Discoloratio.py file, the LED display RGB colors.
Choose_Color.py
#Define colors rgb9 = (0,255,0) #green lcd.setCursor(0, 0) #Set the position of cursor # print the number of seconds since reset: lcd.printout("Waveshare") #Print the string lcd.setCursor(0, 1) #Move the cursor to second row. lcd.printout("Hello,World!")#Print the string lcd.setRGB(rgb1[0],rgb1[1],rgb1[2]); #Set the back light
Discoloration.py
t=0 while True: r = int((abs(math.sin(3.14*t/180)))*255); #RGB changeas as time goes g = int((abs(math.sin(3.14*(t+60)/180)))*255); b = int((abs(math.sin(3.14*(t+120)/180)))*255); t = t + 3; lcd.setRGB(r,g,b);#Set the RGB data again. # set the cursor to column 0, line 1 lcd.setCursor(0, 0) #Set the curson to the first row. # print the number of seconds since reset: lcd.printout("Waveshare")#Print the string lcd.setCursor(0, 1) #Set the cursor to second row lcd.printout("Hello,World!")#Print the string time.sleep(0.3)
