Read parallel data that is valid in every falling edge clock nucleo-h743ZI2

HelloI have an external adc with 2 parallel output pins each is 1 bit (2 bits) total, with clK_out pin, I am trying to read the parallel pins using nucleo-h743ZI2 (480Mhz), I followed [AN4666] example to receive the data1, clk_out is connected to PA6...

On STM32U585 the GPIO G are not driveable (while others are fine)

Hello, While trying to setup an UART connection with a STM32U585ZIT6, we realized that it was not possible to drive the G connectors. To isolate the issue we tried to drive others GPIOs and they are totally fine while GPIOs G remain stuck at GND. We ...

stm32f103, i2c, bit start ignored if not set bit ACK ??

according to the documentation for the iic bus, devices must create start conditions, even if the devices ignore the ACK bit, but stm32f103, in fact, ignores the start bit without the ACK bit. if this is not the case, then where is it written in the ...

HRTIM burst mode missing pulses in one period

My application is using HRTIM in burst mode: PWM is generated part of the time by specifying a period and an idle/run duration based on common tick (TIMA counter).Period (HRTIM_BMPER) is set once at init and idle duration (BMCMPR) updated every 20us....

I cannot locate the STM32H757 chips for sale anywhere, at least not at anything below extortion level prices. On the other hand the STM32MP1xx series are available everywhere and are still at reasonable prices. Is this a push to shift technologies?

Should I give up on the STM32H series and move to the STM32MP series?

trying to read 8 bit port reading and writing . it's working but it's correct?? uint8_t pins = GPIOA->IDR; if(pins == 0xFF){ GPIOC->ODR=0xF000; } else { GPIOC->ODR=0x0000; }
