[STM32H7] Spi Impact On Adc Module(brings larger noise)
When we test adc small signals, we found all spi have impact on adc1 and adc2 module, which leads unexpect singals even we use fund HDs of it.Detals as below:--Environment:Save 6400 points at different conditions,1. spi2 or spi4 work and really has i...
FDCAN data issue on serial Monitor
i have used the board nucleo stm32h745 Board.i have used can 1 and can2 for data exchange but my data is also showing with some simple text ,screenshort is attached. i am sending voltage text at can1 and hello at can2,and but i am getting some text w...
How to calculate Tim3 value for 192 KHz and 84MHz clock
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?
Resolved! serial data droping
i can not get full text msg ,some alphabats are missing each time .how i can solve this ?
Timing issue when TIM10 interrupts HAL IWDG macro
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...
Resolved! STM32H743 Incorrect ADC measurement.
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...
ST microcontroller Carbon footprint
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
SPI Transmitting and Receiving Data Not Matching
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...
QSPI External flash loader
"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?"
