Using Tim3 with 84MHz clock, and need an 192 KHz trigger, for 96 KHz the prescaler is 875-1, clearly half that is a fraction, the calculators mentioned on line no longer work, is there a solution?
i can not get full text msg ,some alphabats are missing each time .how i can solve this ?
I am using a STM32F746VET6 to drive time critical signals on up to 14 pins. I am bit banging these signals in the ISR. I was surprised to find after a benign change I started to have jitter in these signals. I tracked it down to the ISR firing during...
I am having some issues getting meaningful values out of my ADC. At the moment I am capturing ADC samples with the polling mode with the ADC pin being set to approximately 3.2v and 0v. When I check the sample results I am seeing around 20000 for capt...
Hi, I would like to know if it is possible to have the carbon footprint of ST32 microcontrollers. I searched around the websites but I cannot find this type of information.Thanks
Hello,I control an ADC with SPI interface of the STM32F44 microcontroller. The ADC datasheet is in the link, https://intantech.com/files/Intan_RHD2000_series_datasheet.pdf . I set up global variables as read, write, and calibrate masks. The I call t...
"I want to make a QSPI flash loader and I'm watching ST's video series (it's a bit old). I'm using an STM32F446RE. Are the function prototypes shown in the video sufficient for the flash loader to work? Do you have any advice you can give me?"
I'm essentially trying to swap the RAM modules between the two cores on the STM32H755 so that all data in RAM used by the M7 is in SRAM1-3 and for the M4 is in AIXISRAM, but I'm observing some issues in startup behavior on the M4.From my understandin...
The alarm time set properly but interupt in half time &sometimes I not came,please share if any one have idea
