Hi ,I am writing multiple chunk of each 48 bytes to Flash by following flash programming sequence mentioned in STM32 U5 Reference manual. However some chunks are written properly where some chunks are still remains 0xFF. Please let me know if anybody...
Hi, I am trying to implement PWM generation on PC06 from TIM8. The cubeMX is showing following warnings and not generating the clock on desired PIC_PC06??RGB LED is Adafruit NEO Pixel 7 https://www.adafruit.com/product/2226See the attached images and...
I am working on a project that uses a PWM on a timer to drive a buzzer. When the buzzer stops I need to set the output compare signal high. The timer set ARR to 250, and the compare value to 125, giving a 4kHz square wave with a 50% duty cycle. I...
I made several changes in ethernetif.c pbuf_ref(p); if (HAL_ETH_Transmit_IT(&heth, &TxConfig) == HAL_OK) { while(osSemaphoreAcquire(TxPktSemaphore, TIME_WAITING_FOR_INPUT)!=osOK) { } HAL_ETH_ReleaseTxPacket(&heth); } else { pbuf_free(p); } ////...
Dear All,I want to use trace on STM32h755So kindly let me know which trace/debugger has to use and what are the pins required.
Hello,On my project, I use FDCAN1 and FDCAN2. FDCAN1 is working perfectly fine.On FDCAN2, I can transmit data successfully (with the CAN ID 0xBEEF), but when I want do receive data, the Rx callback is never called, nor the IRQ handler (the CAN ID fil...
the code generated for my channels if i initialize this channels and hadc1.Instance = ADC1; hadc1.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV2; hadc1.Init.Resolution = ADC_RESOLUTION_12B; hadc1.Init.DataAlign = ADC_DATAALIGN_RIGHT; hadc1...
Hello everyone,I have been working on a custom bootloader for the STM32H735 microcontroller and I am encountering an issue when attempting to jump to my main application stored in external flash memory. Here's a brief overview of what I've done so fa...
Hello,I am trying to send the message from my USB-CAN Analyzer to my board STM32F407 discovery board, but I am unable to do that. HAL_CAN_GetRxMessage(&hcan1, CAN_RX_FIFO0, &rx_header, rx_data); // Process received message handleReceivedMessage(...
Hi, I am working on a realtime audio DSP product using the STM32H7 with a AS4C4M16SA-7BCN SDRAM chip for long delay line memory. I am using the FMC controller with the settings in the attached photo:The product processes an incoming audio stream in r...
