    i2c_scanner can't see 9250 chip on Teensy 4.0, works on Uno.

    How is that different from the code I posted originally, where I showed 19: scl0, 16: scl1 ? void setup() { // teensy 4.0 pinout // Wire.setSDA(17); //18: sda0, 17: sda1 // Wire.setSCL(16); //19: scl0, 16: scl1 Wire.setSDA(18); //18: sda0, 17: sda1 Wire.setSCL(19); //19: scl0, 16...

    That seems to be the what I have already posted here twice myself. It shows SDA0=18, SCL0=19 . That is where I started and you told me it was wrong .

    OK, I reinstalled from your installer on my 1.59 IDE. Looks to returned to sanity. Scanning Wire... No I2C devices found Scanning Wire1... Device found at address 0x69 (MPU6050,MPU9050,MPU9250,ITG3701,L3G4200D) done Scanning Wire2... No I2C devices found Thanks for the support, that's...

    Yes the Arduino ide sucks. I installed the new one and after it had tried to steal my proprietory code and export it some unknown "cloud" location without so much as a thank you , I had to cut the network. Looks like I'll have to run it in a sandbox or go back to the old junk. I connected by...

    Cool. Now I no longer have a Teensy board at all. Not the usual Teensy 3 and Teensy 4 entries in the port menu. I do get get ACM0 port but if I try to upload to it, it disappears. I can't believe the time I'm wasting on this just to get a basic connection.

    Hi, I want to connect to a giro/mag MEMS device form Teensy 4.0 but it does not seem to work. I have two examples of Chinese allegedly GY6500/9250 9 axis mems boards. My Teensy code does not seem to find them so I ran the standard i2c_scanner sketch from an Arduino Uno and it was fine...
