Hi,I'm evaluating the ISM330DHCX by connecting it on a board with a linux device (imx8) through I2C. (using the st_lsm6dsx - (compatible = "st,ism330dhcx") device.All of this seems to work out of the box, and I can read accelerations through IIO sysf...

Hi,I have a question regarding the backup SRAM in the STM32U5. The reference manual is not clear about this:On the one had, it mentions the following Which seems to indicate that it is possible to place the device in standby without powering SRAM2. H...

Hi,I making a product that has the STM32U5 running from a battery, most of the time being in one of the low power modes. I can use the debugger to .. debug my code, step through it, use SWO etc, and this all works great. However, as long as the debug...

Hi,I am working with what I think is the latest STM cubeMX:But, I am hitting an issue contantly that during debugging, on certain "lines of code" the debugger hits some unexpected condition, and then decides to exit, automatically stopping the debugg...

The issue ended up being nothing related to I2C at all, but a delay timer issue in the driver code.The linux driver I was using lacked the fix from https://github.com/torvalds/linux/commit/ea85bf906466191b58532bb19f4fbb4591f0a77e. Basically it did no...

The reason they look "crisp" imo is because I lowered the frequency from the theoretical 1Mhz to 50khz. Slow anything down sufficiently, and it will look like a perfect square, no matter what the pullups/driving.

(And by the way, for anyone reading this for the first time, perhaps this helps to more quickly absorb the info): - flash line: amount of bytes to be e.g. written/read in one go (halfword,double word, ..)- the flash line "not being writable" => Bits ...

I might be off here, but I'd like to understand the impact of this. I was considering using x-cube-eeprom, but then found this topic. If I am correct: - This library defaults to writing 64 0-bits every boot to guarantee data integrity. => If the devi...
