I'm writing a small HAL of my own for the STM32F1 and I noticed that sometimes the DMA would read in the wrong order for seemingly no reason. After several tests, I came up with this code: const std = @import("std"); const microzig = @import("microzi...
Greetings,We have implemented a USB peripheral on the STM32G474RE discovery board using code that runs properly on the STM32WB and STM32F0 parts. On the G474, the USB setup completes, but the USB bus quickly suspends after the completion of the conf...
Hi, We use NUCLEO-H753ZI. Input signals to all ADCs are 60Hz/50Hz, the sampling clock is set as 5Mhz. The sample time is set to 12.clock cycles. We found the cross talk (interference) between two ADC adjacent channels in STM32H753 assigned ...
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?
