I did this

for my_address in range (7):
	AD0.value(my_address & 0b001)
	AD1.value(my_address & 0b010)
	AD2.value(my_address & 0b100)
	
	print(com.scan())

perfect

Code: Select all

my_addresse = 0b010

AD0.value(my_address & 0b001)
AD1.value(my_address & 0b010)
AD2.value(my_address & 0b100)

like this ?

Hi, how to write the addresses in one go? I use a nucleoF411RE AD0 = Pin('PA0', Pin.OUT) AD1 = Pin('PA1', Pin.OUT) AD2 = Pin('PA4', Pin.OUT) AD2 AD1 AD0 Sequence I2C 0 0 0 0100 0000 0 0 1 0100 0010 0 1 0 0100 0100 | | | | | | | | | | | | | | | | | | | | 1 1 1 0100 1110 Thank you

digikey.fr

mouser.fr

fr.rs-online.com

(those are professional suppliers)
but not the PYBOARD D ? why ?

Thank you

Hi, I have to add the line 7 #define MICROPY_HW_BOARD_NAME "NUCLEO-F411RE" #define MICROPY_HW_MCU_NAME "STM32F411xE" #define MICROPY_HW_HAS_SWITCH (1) #define MICROPY_HW_HAS_FLASH (1) #define MICROPY_HW_ENABLE_RTC (1) #define MICROPY_HW_ENABLE_USB (1) and I have a problem : pat@pat-3000-N100:~/micro...

I'm sorry shaoziyang, i didn't see your answer.

I'm going to add this line and follow the instructions.
(If i have any problems, I can ask for your help ?)

Thank you

thank you for your response.

In DFU mode there is a USB port on stm32f411 ? PA_11 and PA_12

I try to rebuild a firmware (it's the first time, I hope it's not hard)

Hi, I try the tutorial with a board nucleo411 but it is possible ? I don't know how to access the boot file ... I don't see : usb_mode >>> MicroPython v1.12-371-gf534b9976 on 2020-04-15; NUCLEO-F411RE with STM32F411xE Type "help()" for more information. >>> import pyb >>> pyb. __class__ __name__ mai...

Hi jimmo

I'm sorry, it's because of my English.
You have answered my question. I'm going to rebuild the firmware.

Thank you very much

Hi, I work with a nucleo F411 but i have a problem with UART on the "ARDUINO HEADER". I use the UART6 on the NUCLEO HEADER but it's missing on the ARDUINO-HEADER. Can I redirect the UART6 to the pin's of UART1 without rebuilding the firmware ? In mpconfigboard.h there don't UART1 // UART config #def...
