![]() This make the communication not byte to byte controlled as I want it to be for my need. I realized that if I wanted to make an Arduino slave, when receiving from master, it actually reads from a buffer that is already previously received. But letâs start with the problem found in the Wire. When the limitations were somehow fixed, even though the small number of modifications (it is somehow a sort of hacking of the library) I found that the my final result were so useful to me that I thought was worth to write a short article about it. Then, when experimenting with a portability of a project in the Arduino environment, I started to trying the official Wire library, discovering some incompatibilities for my needs. Can you help? Thanks.I have spent a lot of time on playing and later working on the I2C buses. I almost always used self developed libraries, both for learning and job requirement purposes. ![]() Iâm probably doing something dumb, but Iâm not seeing it. It supports JSON serialization, JSON deserialization, MessagePack, streams. 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). ArduinoJson is a JSON library for Arduino, IoT, and any embedded C++ project. Iâve tried it at 100KHz, 400KHz, 1MHz with the same result. It also provides adapter classes to allow the application to use the library and various third party I2C libraries using the same API.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 This library provides 2 of the smallest and fastest software I2C implementations ( SimpleWireInterface and SimpleWireFastInterface) for Arduino platforms using a minimal AceWire Interface described below. 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++) Hereâs my libdaisy version: #include "daisy_seed.h" Serial.println("No I2C devices found\n") Äelay(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") ![]() Hereâs the i2cScanner code from Arduino that Iâm porting: #include įor(byte address = 1 address < 127 address++ ) ![]() I wonder if youâd have a look at my code? I thought I understood everything based on your comments, Stephen, but Iâm having no success. ![]()
