Does STM32 support dual-ADC multi-channel sampling? For example, ADC1 enables IN1 and IN2, and ADC2 enables IN3 and IN4. Is the storage method in the adc_buffer as follows? adc_buffer[0]: High 16 bits = ADC1 IN1, Low 16 bits = ADC2 IN3 adc_buffer[1...
Can you share the routine for configuring USART2 interrupt transmission and reception on stm32N657? It took a long time to configure, but it can only send, but the receive interrupt cannot be triggered!
I am trying to write a ethernet loopback test and I am unable to set the destination MAC address (FF:FF:FF:FF:FF:FF) to broadcast to. Since this is for testing, we want to avoid using NetX.Is there an example of HAL_ETH_Transmit and HAL_ETH_ReadData ...
We are currently using the STM32G0B0VET6 microcontroller (100-pin LQFP package) in our design for interfacing a 480x320 ILI9488 TFT display via the SPI interface. Our hardware is already finalized and PCBs have been fabricated accordingly.During our ...
Hi,I have a well functioning application transmitting on uart4 using GPDMA1 CH1.If I turn on DCache, then it does transmit the correct length, only all characters are 0x00 (no problem in turning ICache on).In HAL_UART_Transmit_DMA(huart, (const uint8...
Hello,I try to use I2S in full duplex mode master with DMA but it doesn't work as expected.The I2S is configured in 24 bits @32Khz.DMA TX and RX are configured in half-word circular mode.I can send data manually but if I loop the input to the output ...
How to PWM input capture based on its frequency and duty cycle.
I connect the PB9-BOOT0 to VDD, then power up the board, but it just run from flash(application program), not the bootloader, what's the matter? I am not firmilar with ISP, I suppose it should enter bootloader, and wait for ISP program to communicate...
Hi,I am injecting a UART DMA error by using DTCM memory and DMA2. For example:// Induce a DMA error by using DTCM RAM for DMA2 which is inaccessibleif ( HAL_UART_Transmit_DMA( huart, transmit_buffer_dtcm_memory, num_bytes_to_transmit ) != HAL_OK ){//...
So I've created a project and am trying to use the HAL_delay(10); but it gets stuck at this function when im trying to debug. I have been changing the clock and enabling the TIM2 so I don't know if i've messed something up. Here are the settings that...
