Hi,is there anyway to insert a delay between the start generation address byte transmission and the first data byte reception from the slave device? I have tried reading 0 bytes from the slave to prevent the reading of the first byte but that sets th...

Hi,using CubeIDE with CubeMX, is is possible to "check" or "detect", for conditional compiling, which UART ports that are enabled? In the MX-generated USART.C you will find all the handles for the available UARTs but AFAIK, you can't conditional comp...

Hi,I am interfacing to a TI device that requires a 100us delay between each I2C byte and I can't think of any way that doesn't involve "hacking", i.e. using timer delays, interrupts, etc. Is there a more elegant way to do it using the ST I2C implemen...

We have a project on an STM32H750 using FreeRTOS and I am trying to access an I2C device after the peripheral inits but before the FreeRTOS init and scheduler start in Main.c but I get no interrupts from the I2C port. I have checked that the interrup...

Got it all working except there seems to be no way to get the I2C port, during a read, to halt after the address byte. I can read 0 bytes and the I2C terminates with the Transfer Complete ISR bit set. Unfortunately, the only way to clear that bit is ...

Tried that, I all works except for reads where I have no way of inserting the delay between the address and first data byte.

TI MCT8316A. They realize this is a fault and "it will be fixed in the next chip revision" which doesn't help me since it is already used in hundreds of products.

I may have been unclear, what I mean is to, as a master doing a read of a slave device, on the MCU side put in a delay between the start/address byte and the first data byte read. My slave device does not have clock stretching but instead requires "...

I have more or less chosen that way but instead of doing all the customization in MX, I will have a Defines class included into my main class. In that way, everything is collected in a single source file.

I2C - Delay between address byte and first data byte when reading

Detecting available UARTs at compile time

Is there any way to "pace" bytes in an I2C transmission?

Interrupt driven I2C traffic not working before FreeRTOS is up and running.

Hi, is there any way to "enforce" a CubeIDE version in code, e.g. a static_assert()? Regards, Goran
