Sorry for a noob question...The DS for STM32H7 (DS12117 Rev 7, 3.42) says that a PHY can be clocked using 25 MHz from the microcontroller. The PHY we want to use, KSZ8873, has its own connection for 25/50 MHz oscillator. We'd prefer to put only one ...
Hello,I do not know if this question was asked here before so i will apologize in advance for spamming.I want to build an application which is based on the HAL libraries and i do not know if i can use this libraries for free or there is some legal n...
hi I looked for a tutorial on dma receive i2c but I didn't find it, Itried with dma receive uart and it works perfectly:int main(void){HAL_Init(); MX_GPIO_Init(); MX_DMA_Init(); MX_USART2_UART_Init(); MX_USART6_UART_Init(); /* USER CODE BEGIN 2 */ HA...
I was initially using B-L475E-IOT1A board to test AWS freertos and it works all fine.Next, we needed to somehow support OTA on our product and found out thatAWS freertos also supports OTA and would like to try and implement it but couldnot find any s...
Hello Community,I would like to report a bug on STM32G0 HAL library provided by ST. As described in the object there is a bug on HAL_SPI_TransmitReceive function: basically an hard fault occurs if the receiving pointer is not 32 bit aligned.This is ...
I get the impression all the downloads/packs, such as https://my.st.com/content/my_st_com/en/products/embedded-software/mcu-mpu-embedded-software/stm32-embedded-software/stm32-ode-function-pack-sw/fp-atr-lora1.license=1568668120994.product=FP-ATR-LOR...
In 'STM32G0xx_HAL_Driver\Src\stm32g0xx_hal_dma.c', Line 1032, 'hdma->DMAmuxChannelStatusMask = 1UL << (channel_number & 0x1cU)' , why the channel number is anded with 0x1C? shouldn't that be anded with 0x7f?
Hi,It seems a recent update from Windows introduced a driver problem with the Joystick demo code (I'm running it on a STM3210B-EVAL evaluation board). After some investigation, I linked it to a wrong driver being installed when I connect the board (s...
I am trying to receive raw ethernet frames on my STM32F746G and i want to wait for their arrival and filter them by etherType.In the reference manual only filtering by Source or Destination address is possible and i don't seem to understand where to ...
Hi everyone, when I used STM32CubeMX to generate initial code and would like to use HAL library of HAL_I2S_Transmit_DMA to transmit data to device, I didn't get any signal output from all pins Have someone meet this problem? Could you please give som...
