We have facing issue on microntroller we have recieve we have serial product and curretly we are using STM32F072VBT6 controller but we have order new lot and we are recieve STM32F072VBT6 2 and both are behaviour diffrent so what is major diffrence be...
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...
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...
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...
