1. arduino使用I2C总线读写外置EEPROM芯片(24Cxx)也不是什么难事 可以使用下图的Wrie库2. I2C通讯内容多了一点,虽然使用Wrie库依旧能节省很多在信号时序、读写延迟上的代码量,但是读写的数据要做类型变换,指针引用、寻址读写过多,考虑搭建外部电路还挺麻烦,这个留在大家对arduino更熟悉以后再说3. 在几年以前,...
I'm embarrassed to say I can't get an I2C LCD to work on my ESP32 module. I tired 3 different LCDs that work with UNOs, and NANOs (tested) I tried 2 different ESP32Wroom modules, thinking the first one that I never used may be "bad" I have tried using the LCD in the ...

Re: I2C read always get first byte Sun Sep 16, 2018 12:52 am 1) First, the message is being built when I change a variable instead in OnRequested. 2) In my Pi side, I send a i2cget with address (the Arduino get that address in OnReceived) and I store that in a global var...
