I´m trying read bytes from Adafruit I2C Non-Volatile FRAM Breakout module (ic MB85RC256V from FUJITSU) in my STM32F746IG custom board.Using FW 1.16.2, I can read 512 bytes using HAL_I2C_Mem_Read_DMA.Using FW 1.17.0, The I2C stops (clock pin goes down...

Hi pavel,I also found no limitation in the documentation.About the recommendation:1) read 510 bytes: (first read 255 and after more 255): OK. Success. I can read as many bytes as I want using several 255 bytes read command in sequence.2) read 511 by...

Hi TDK,I understand the hardware limitation on the I2C_CR2 register and the library's limitation on the hi2c->XferSize. However, hi2c->XferCount is not limited in the library (same link above but line 2986) being used in the I2C_Mem_ISR_DMA interrupt...
