I have been struggling to get USB CDC device to work for the Nucleo without any additional USB peripherals. USB CDC works perfectly fine when I use the DISCO-board connected through the USB-micro, with the same MCU as the NUCLEO. I have connected a c...
This is very weird problem as I have never experienced this kind of problem before.The board is hooked up to several NPN type limit sensor and connected PE0, PE1 etc.Every pins are defined as EXTI with Rising/Falling edge trigger and has been working...
Dear All,I have a STM32F407-Discovery Kit, I have a problem that when I Power up my Discovery Kit it takes 2 to 3 Seconds to initialize, and during this time there is Garbage values on GPIO Pins. Please tell me what is the problem?
The product page for STLINK-V3SET lists the following:Multi-path bridge USB to SPI/UART/I2C/CAN/GPIOs I can see in the STM32CubeProgrammer CLI that use can use the SPI/I2C/CAN/UART functions. But can you control the state of the GPIO 0-3 pins in som...
I am a 10yr Arduino IDE programmer and I have a cheap ST-Link V2 (Canaduino). M5Stack provides a copy of the firmware and I would like to experiment with making it a stand alone MCU that could read inputs and respond with outputs. I would like to do ...
When we enable the RTC feature on our controllers, we do a calibration in Production against a GPS-locked 10MHz signal. Usually, we'll use the T2 ETR to clock the 10MHz signal in and an RTC-generated 1Hz signal on one of the other T2 channels such a...
can some one please tell me why is the schematics the pd8 is connected to gnd?here is a picture of the schematics
I started from the documentation of both discovery board and MB1280-B1 STMOD board.They both state, that the pin number 2 of STMOD+ (P2) connector of the discovery board is connected, I quote: "SPI2_MOSI/ USART2_TX (PC3/PD5)".So - USART2, pin PD5. Th...
I have STM32L4P5CGU6 (48 pin).Pins PB5, PB4, PB3, PA15 are used as SPI1 with another IC which has 3.3V levels.As well as PB6, PB8, PB9 as custom input GPIOs with voltage levels of 3.3V.VDD (pin #9, pin#24, #48) -> 1.8VThey all seem to work fine, howe...
I am currently developing a touchgfx GUI for a custom board which is based on the STM32F429-DISCO, therefore I use said board for the fundamental development. While initializing hardware button controll via GPIO_EXTI lines I have run into a strange i...
