Arduino library wire10/5/2023 What if I want to use a library, but with a different I2C port? You have to go into the library and modify quite a bit to get it to work. But as I attached things like the HMC5883L to the SAMD21, I quickly realized that most libraries assume you will be using Wire.write(). It’s an amazing board because it’s got multiple serial ports and multiple I2C ports. Can you help? Thanks.My AVC 2016 vehicle used a handful of our SAMD21 Minis. I’m probably doing something dumb, but I’m not seeing it. I can tell that something is happening, because the code completes in 3-4 seconds with no pin connections, it takes a bit over 60 seconds (as expected to scan 127 addresses with a 1/2 second timeout). I’ve tried it at 100KHz, 400KHz, 1MHz with the same result. Seed.PrintLine("I2C device found at address %x !", prAddress) Īnd the output when the Seed is connected (pins 12/13 on the pinout): Daisy is online Int prAddress = (address < 16) ? 0 : address = _i2c.TransmitBlocking(address, &testData, 1, 500) Static constexpr I2CHandle::Config _i2c_configįor(unsigned char address = 1 address < 127 address++) Here’s my libdaisy version: #include "daisy_seed.h" Serial.println("No I2C devices found\n") ĭelay(5000) // wait 5 seconds for next scanĪnd the output (connected via A4/A5 to 3 daisy-chained (!) GPIO boards: Scanning. Serial.print("I2C device found at address 0x") Here’s the i2cScanner code from Arduino that I’m porting: #include įor(byte address = 1 address < 127 address++ ) I wonder if you’d have a look at my code? I thought I understood everything based on your comments, Stephen, but I’m having no success.
