SPI stops working when enable I2C?
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...
STM32 memory out and how avoid that
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...
Which STM32 controller has secure booting capability?
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...
Timmer input STM32F429
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...
Reading Encoder pulses using external interrupts
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...
Resolved! How to choose from several ports on the same pins on stm32 mcu
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?
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?
Resolved! TCXO HSE to NUCLEO f446re
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...
STM32F334: HRTIM DMA Transfer error when send to CMP1xR register
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...
