Fig 9 of the STM32F429 datasheet it effectively states that the external source clock/signal has to be 1/3 of the Timer clock – makes sense as you want to ensure you capture the edge of the input signal. However, the Ref manual section 17.4.3, the re...
I'm using STM32L451VCI6 MCU to read pulses from a rotary encoder attached to the shaft of a stepper motor using external interrupts. I'm incrementing a counter at rising edge of interrupt.According to spec of the encoder, I should be able to read 400...
Hello,I am looking at the STM32G041j6m6 with the soic8 package and as you can see (screenshoot from the datasheet) it has several ports wired to the same pin. Which is the register that selects which port is actually wired to the output pin?
Does the STM32U5 series support PD3.1 standard: in hardware?in ST-provided firmware?If not, is there any future upgrade planned to make it support PD3.1?
I need a accurate time source for time synchronisation between boards and timestamping of sensor data so want to add a accurate HSE. I'm currently considering a 7N-26.000MBP-T 26MHz TCXO connected to OSC_IN. I would have a 10nf bypass capacitor and d...
I try to modulate a sinus signal with the PWM of the HRTIM.Therefore i had used a table of 16 points, the PWM freq. is 640Khz and on the PWM output (TA1 of timer A).After a RC filter i becomes a sinus signal of 40KHz. The DMA send on every TA1 set, t...
hi thereI have a project with STM32f103c8t6 blue pill. here I connect a 12pF capacitor to pin PA2 and PA1. PA2 is GPIO_OUTPUT and PA1 is ADC.first: PA2 is set HIGH to charge the capacitor and then goes LOW right afterwards. here is my while(1) codetu...
hi,i'm trying to read the external adc value using spi1 + dma (MAX11198ATE+)i though it works fine but, sometimes it returns wrong values i have checked the waveforms of SPI MISO/MOSI, SCK (hardware)but there was no error forms. it seems to be matche...
I feel that CubeMx and HAL will reveal no solution to this but I still would like a solution to this problem. The GPIO pins on the H7 are on the AHB4 bus, as is BDMA2. I wish to set a timer to cycle through a buffer toggling a GPIO port outputs. Is t...
