But I looked at my STM32L4 examples. My question is simple, I just want to send 20 bytes of data from a STM32F103C8 blue phill card in i2c slave mode to a raspberry pi 3 in master mode, I use STM32Cube IDE can any other IDE work for me.c code after sending slave address there is a loop ( while (hi2c->XferSize > 0U)) that sends bytes which we want to be transmitted to slave. Requirements. In polling mode, also called blocking mode, the application waits for the data transmission and reception. In this tutorial we will interface an I2C based EEPROM with our beloved STM32. 박라희 19 Possibly the problem is that the BME280 supports single byte reads and multi-byte reads (until it sends a NOACK and stop). 이번에도, 보안칩 회사의 철통같은 보안으로 메뉴얼 조차도 보안적으로 설명을 좀 빼먹어서,i2c 시퀀셜 송/수신 함수까지 써 보게 .그래서 .
