Do you mean arm board? I checked the mpu-6050 at Aduino_mega But the mpu-6050 did not matter I have raspberry pi, orangepi zero and orangepi zero plus but also same symptom in orangepi zero(not working I2C) before It worked in orangepi zero using I2C device It seems to be caused by an update issue

[twi_para] twi_port = 0 twi_scl = port:PA11<2><default><default><default> twi_sda = port:PA12<2><default><default><default> It seems to have been automatically changed since the update but still i can't use 0x68

@nopnop2002 i try like you but i can't see i2c address it's not working i want to try another way...

Um "i2cdetect" is not showing the devices so it's same result ... also A few months ago an orange pi zero succeeded in connecting i2c but now Orangepi Zero showed same result as the nanoPi neo air Is there no other way to use another address?

no i didn't PullUps on my bus but i connected MPU-6050 Vcc Pin - NanoPi Neo Air Vcc 5v in... oh... if i use NanoPi Neo Air 5v(IN) i have to change 3.3v(OUT)? or 5v(OUT)? and i'm not using pre-fab module

I do not know if the peripherals I think are right, but let me tell you. my peripherals is mpu-6050(accleration + gyro-sensor) Now i using H3 chip and i don't know manufacturer my processor is ARMv7 Processor rev 5 (v7l) hardware is sun8i i used this Wiring - git clone git://github.com/wertyzp/WiringNP and my gpio -v is Copyright (c) 2012-2014 Gordon Henderson This is free software with ABSOLUTELY NO WARRANTY. For details type: gpio -warranty Banana Pro Details: Type: Model A, Revision: 1.2, Memory: 1024MB, Maker: LeMaker That's all I know.

i want to use 0x68 address How can I use the peripherals I want?

thanks your reply you mean change this part [twi0_para] twi0_used = 1 // (enable) twi0_scl = port:PB00<2><default><default><default> // i think Hardware pin number twi0_sda = port:PB01<2><default><default><default> // also pin number but i want to use another i2c address now 0x48 address be used so i want to use another one so your method is not match to this question so what should i do?

Hi i wonder why ISR result is strange first i test in orangepi zero Plus H5 that result is repeated infinite recall function summary - recall infinite function if i input interrupt pin(button) i test result repeat second i test in orangepi zero(H2) that result is only called function once #include <wiringPi.h> #include <stdlib.h> #include <stdio.h> #include <unistd.h> void signal_both(void){ printf("Signal Both\n"); }void signal_falling(void){ printf("Signal Falling\n"); }void signal_rising(void){ printf("Signal Rising\n"); }int main(int argc, char **argv){ int mode=INT_EDGE_BOTH; int pin = 0; if(wiringPiSetup() == -1) { printf("wiringPiSetup Error\n"); } if (argc == 2) { mode = atoi(argv[1]); } if (argc == 3) { mode = atoi(argv[1]); pin = atoi(argv[2]); } pinMode(pin,INPUT); printf("pin=%d\n",pin); if ( mode == INT_EDGE_BOTH) { printf("INT_EDGE_BOTH\n"); wiringPiISR(pin, INT_EDGE_BOTH, signal_both ); } else if ( mode == INT_EDGE_FALLING) { printf("INT_EDGE_FALLING\n"); wiringPiISR(pin, INT_EDGE_FALLING, signal_falling ); } else if ( mode == INT_EDGE_RISING) { printf("INT_EDGE_RISING\n"); wiringPiISR(pin, INT_EDGE_RISING, signal_rising ); } while(1) { sleep(10000); } return 0; } can you explain why result is different? code is same in Orange Pi Zero and Orange Pi Zero Plus H5

Thank you for always kindly responding. have a good day~

Hi martinayotte i have good news i successed uart communication, thank you very much but i wonder why another ttyS1 or ttyS3 pin is not working i heard orangepi zero provide 3 uart pin anyway i add "overlays=uart1 uart3" after checking uart2 and also i tried picocom -b 115200 /dev/ttyS1 and picocom -b 115200 /dev/ttyS3 then ttyS1 note can't use and ttyS3 can use so i tried ttyS3 - connect a jumper pins(i tried 10, 11 40 because GPS just send Data(Tx)) - nothing happen - orangepi zero plus H5 provide just 1 uart pin? thanks for your advise and care i always respect all developers ^^

I erase param_uart1_rtscts=1 and i test serialRead.c I'm use example - serialRead.c -> gcc -o test serialRead.c -lwiringPi -lpthread sudo ./test -> nothing to receive ...

Hi Igor~ i success connect i2c pin ! just add overlays=i2c0 i2c1 like this ... in cd /boot -> armbianEnv.txt but! now i can't connect to uart pin... i tried to add -> overlays=uart1 like this and param_uart1_rtscts=1 but it wasn't work i check dmesg | grep ttyS then [ 1.635332] console [ttyS0] disabled [ 1.655531] 1c28000.serial: ttyS0 at MMIO 0x1c28000 (irq = 27, base_baud = 15 00000) is a U6_16550A [ 1.655587] console [ttyS0] enabled [ 1.676199] 1c28400.serial: ttyS1 at MMIO 0x1c28400 (irq = 28, base_baud = 15 00000) is a U6_16550A [ 1.696663] 1c28c00.serial: ttyS2 at MMIO 0x1c28c00 (irq = 29, base_baud = 15 00000) is a U6_16550A so what should i do? cd /dev/ -> in there i have tty0 to ttyS0~ttyS3

Igor! now i reference https://docs.armbian.com/User-Guide_Allwinner_overlays this site during i try Using custom overlays part, i have question in there they offer some example overlays example overlays is based on H3 chip but Orangepi Zero Plus H5 is based on H5 chip so i think, it is not match what do you think?
