  1. Thank you, it works! [spi0] spi_used = 1 spi_cs_bitmap = 1 spi_mosi = порт:PC00<3><по умолчанию><по умолчанию><по умолчанию> spi_miso = порт:PC01<3><по умолчанию><по умолчанию><по умолчанию> spi_sclk = порт:PC02<3><по умолчанию><по умолчанию><по умолчанию> spi_cs0 = порт:PC03<3><1><значение по умолчанию><по умолчанию> [spi1] spi_used = 1 spi_cs_bitmap = 1 spi_cs0 = порт:PA13<2><1><значение по умолчанию><по умолчанию> spi_sclk = порт:Почтовый Ð¸Ð½Ð´ÐµÐºÑ pa14<2><значение по умолчанию><по умолчанию><по умолчанию> spi_mosi = порт:PA15<2><значение по умолчанию><по умолчанию><по умолчанию> spi_miso = порт:PA16<2><значение по умолчанию><по умолчанию><по умолчанию> [spi_devices] spi_dev_num = 2 [spi_board0] modalias = "spidev" max_speed_hz = 33000000 bus_num = 0 chip_select = 0 режим = 0 full_duplex = 1 manual_cs = 0 [spi_board1] modalias = "spidev" max_speed_hz = 33000000 bus_num = 1 chip_select = 0 режим = 0 full_duplex = 1 manual_cs = 0 [leds_para] leds_used = 0 may be disable audio0 , there spi_miso [audio0] audio_used = 0
  2. Clear. I thought possible as I want to assign ports. I look for how to deal with GPIO PA15 I have Orangepi One, Lite, PC, PC +, and zero.
  3. I manually changed the ports, because the PA15 is not available. spi_dev_num = 2 the answer is the same: root @ orangepipcplus: ~ # python /root/Software/main2.py Traceback (most recent call last): File "/root/Software/main2.py", line 183, in <module> a = APA102 (ledNumber) #amount of led here File "/root/Software/apa102.py", line 65, in __init__ self.spi.open (1, 0) # Open SPI port 1, slave device (CS) 1 IOError: [Errno 2] No such file or directory
  4. im redacted fex and change script.bin but ansver: self.spi.open(1, 0) # Open SPI port 1, slave device (CS) 1 IOError: [Errno 2] No such file or directory and: root@orangepipcplus:~# ls /dev/spidev0.0 /dev/spidev0.0 root@orangepipcplus:~# ls /dev/spidev1.0 ls: cannot access /dev/spidev1.0: No such file or directory from FEX: [spi0] spi_used = 1 spi_cs_bitmap = 1 spi_mosi = port:PC00<3><default><default><default> spi_miso = port:PC01<3><default><default><default> spi_sclk = port:PC02<3><default><default><default> spi_cs0 = port:PC03<3><1><default><default> [spi1] spi_used = 1 spi_cs_bitmap = 1 spi_cs0 = port:PA07<2><1><default><default> spi_sclk = port:PA08<2><default><default><default> spi_mosi = port:PA09<2><default><default><default> spi_miso = port:PA10<2><default><default><default> [spi_devices] spi_dev_num = 1 [spi_board0] modalias = "spidev" max_speed_hz = 33000000 bus_num = 0 chip_select = 0 mode = 0 full_duplex = 1 manual_cs = 0
  5. if not spidev.open (), then simply paste, how it should look like? for example in the upper or this code: def __init__(self,spd=1000000): spi.openSPI(speed=spd) # GPIO.setmode(GPIO.BOARD) # GPIO.setup(22, GPIO.OUT) # GPIO.output(self.NRSTPD, 1) self.MFRC522_Init() I see!)) I try. class APA102: def __init__(self, numLEDs, globalBrightness = 31, order='rgb'): # The number of LEDs in the Strip self.numLEDs = numLEDs order = order.lower() self.rgb = rgb_map.get(order, rgb_map['rgb']) # LED startframe is three "1" bits, followed by 5 brightness bits self.ledstart = (globalBrightness & 0b00011111) | 0b11100000 # Don't validate, just slash of extra bits self.leds = [self.ledstart,0,0,0] * self.numLEDs # Pixel buffer self.spi = spidev.SpiDev() # Init the SPI device self.spi.open(1, 0) # Open SPI port 1, slave device (CS) 1 self.spi.max_speed_hz=16000000 # Up the speed a bit, so that the LEDs are painted faster 8 000 000 is default
  6. Please tell me what to write in the program, so that it was connected by SPI1? import spidev ... """ An APA102 LED is addressed with SPI. The bits are shifted in one by one, starting with the least significant bit. ... void show() Sends the content of the pixel buffer to the strip. Todo: More than 1024 LEDs requires more than one xfer operation. """ def show(self): self.clockStartFrame() self.spi.xfer2(self.leds) # SPI takes up to 4096 Integers. So we are fine for up to 1024 LEDs. self.clockEndFrame() """ void cleanup() This method should be called at the end of a program in order to release the SPI device """ def cleanup(self): self.spi.close() # ... SPI Port schliessen
