Hi,My slave device has only one bidirectional data line. Now I want to configure the SPI in the half-duplex mode. And I noticed that the reference manual gave an descripiton of 1 clock and 1 bidirectional data wire.I want to ask if ST has peripheral ...
Hi,I would like to know if MCUs of ST can operate in a vacuum environment.Thanks
Hello, I'm trying to use I2C and SPI simultaneously on an STM32F103C6TX.Both are working properly when only one of them is activated. However, when activating I2C peripheral with SPI already activated, SPI clock still works but the MOSI pin stops wor...
Hi there,here i'm for ask another help. I compile my program with keil and i read this data :Program Size: Code=15988 RO-data=360 RW-data=24 ZI-data=2088 How i can interpret ? I use one STM32G031F4P6 wher i have 8K of RAM and 16K of program. So i ju...
Im currently building boot loader to securely boot the firmware by signing the firmware images and verification during the boot of the firmware.So i'm using controllers like stm32f411,stm32f446,stm32f746 and stm32h723 ,I believe from the available do...
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...
