You might also be interested in the Reference manual and the Errata sheet of the Microcontroller as well which is STM32F103C8, STM32F103R8 STM32F103V8, STM32F103T8 STM32F103xB STM32F103RB STM32F103VB, STM32F103CB, STM32F103TB BGA100 10 × 10 mm UFBGA100 7 x 7 mm BGA64 5 × 5 mm VFQFPN36 6 × 6 mm LQFP100 14 × 14 mm LQFP64 10 × 10 mm LQFP48 7 × 7 mm UFQFPN48 7 × 7 mm www. I have a master and slave program which runs perfectly fine when the clock frequency for i2c communication is set to standard (100000L) which is default. DMA behavior is the same over STM32F2, STM32F4 and STM32F7 Series unless otherwise specified. To do this we need to use a Serial FTDI board. Outline. Communication SPI, I2C, CAN, USART, USB, Device. It could be the F103 HAL I2C slave library for interrupt code is broken without STM wanting to admit it and the same code on another MCU may work due to HAL differences. Click on the pin#13 and set the gpio as output. However, you can still use the built-in STM32 library and do the essential wiring STM32F103C8T6 – giao tiếp RFID RC522. urrypzozifnzzlmfbruj
