I have implemented a basic I2C between STM32H7 (Main) and STM32F4 (Secondary) processor. I am using an array of size 6 to transmit from the Main CPU to Secondary CPU using I2C in IT mode.The HAL API for I2C requires the data_buffers to be of size uin...

I am using the STM32H753 ARM Cortex M7 processor(Package LQFP208).My SYSCLK runs at the max. speed of 480 MHz and I want to configure my I2C1 (polling) in the Fast Mode (400KHz). I have configured the GPIOs and the modes but I am stuck at the "I2C_TI...

Hello all, I am new to embedded programming and I am practicing embedded program and trying out new things. Recently I was trying to create a new text file on my SD card by referring this video posted by ST :- https://www.youtube.com/watch?v=I9KDN1...

Oh yes, you were right with the size thing. I was implementing it incorrectly. I have added the solution as an update section to the original post.Thank you for your insights though!!!

Another concern of mine is, even after typecasting the tx_dataFrame and rx_dataFrame to 'uint8_t' inside the HAL I2C TX and RX API, the memory layout for the databuffer displays the loaded data as a 32 bit instead of an 8 bit data. I tried implementi...

Thank you for getting back to my query. The way I have been implementing the sizes for the TxDataFrame and rx_dataFrame is as follows:Because, the HAL API accepts the buffer size of uint16_t:uint16_t txDataFrame_Size = sizeof (tx_dataFrame)/sizeof(tx...

Thank you.

I never heard about this macro, but I will give it a try. Thanks for the suggestion. Do you know a sample I2C program for the H7 processor to configure the I2C using registers?The web has a lot of I2C programs for various types of STM32Fxxx processor...
