Hello,Trying to implement SPI bus (Master only) to transmit 16 bit to LCD, utilize linked list GPDMA ch 6, I looked at the UART linked list example and tried to modify it to work with SPI with no success, only the first half word is sent and then it ...
Reading through the docs for the STM32 G474 FDCAN TX sections, it seems like if FDCAN is in FIFO mode, there is no way to cancel a pending message. The message can only be dequeued from being sent. If this is the case, how should one handle the case ...
Hi, I want to start using the STM32U073KCU6 MCU in an upcoming product but don't have a ton of familiarity with STM MCUs. My attraction to the device is based around the integrated USB functionality and I am trying to figure out if it can be field ...
Hi,I have a situation where the configured watchdog on my STM32L031 does not trigger even though the MCU gets stuck in an I2C function. In my program flow, I first run through some initializations (as well as I2C_Init()) and then start the IWDG (Star...
I am configuring wakeup pin PA0 to WAKEUP1 by wirting 01 (pull-up) at WKUPPUPD (PWR_KUPEPR) as said at RefManual by using "HAL_PWREx_EnableWakeUpPin ". PWREx_WakeupPinTypeDef sPinParams; sPinParams.PinPolarity = PWR_PIN_POLARITY_LOW; sPinParams.P...
An application created directly for the configurator where TIM3_CH! is set to PB4 where the internal clock is either ticked or not ticked it crashes at if (HAL_TIM_PWM_Init(&htim3) != HAL_OK) with No source available for "uwTickPrio() at 0x20000004" ...
The 32-pin package doesn't seem to have any kind of external clock input at all, and the device does not feature "crystal-less USB". How do we provide a stable clock for USB then?
Greetings,I have acquired Nucleo-U031R8 as I was searching for ULP controllers and specification of this one was good. I am currently trying to lower current consumption as low as possible. Previously, I have used Nucleo-L073RZ where I was able to ac...
Can the STM32F469I-DISCO support reading/writing a FLASH Drive on its UTB-OTG interface ?What software does it need for this ? (Pardon my ignorance - I'm a Hardware guy!).
I'm using STM32 with HAL and LL drivers (H7 and G4 families, in particular, but I think this can be a general question) and I trying to avoid being forced in recursive faults when reading a flash location with broken ECC. In my application it may hap...
