Using a Nucleo-F411RE board modified to have 8MHz HSE crystal oscillator and running the OTG peripheral in forced host mode, we are working on implementing our own host stack. With the current code no IRQs trigger until a device is physically attach...
SEE EDITI am using the STM32H7B3I-DK. I am trying to write my own simple SPI ISR to handle transmitting and receiving of just one byte I have gotten the slave working with my ISR (while master used HAL). I am now implementing on the master and having...
The Ethernet reset is not clearing (ETH_DMABMR_SR in DMABMR).I am having a similar issue as others but have not seen a solution in the forum.I am working with the stm3210c-eval board. I know it is no longer available; but it has a version of the proc...
Hi, Looks like the HAL driver for the STM32f7xx ADC is missing a case for using the software start of the ADC2 peripheral in the HAL_ADC_Start_IT function. Starting from line 1128: else { /* if instance of handle correspond to ADC1 and ...
Hello,I'm using the STM32F767ZITx MCU and the lwIP library to transmit and receive UDP packets every 1 ms.Everything works fine but sometimes, after the ARP table has expired, UDP packets are no longer transmitted for several seconds even though my S...
Hi, I am having a strange ADC problem on my STM32L431 device. I am sampling 6 channels without DMA using polling method with the following code: while (1) { /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ ADC_Select_CH0(); HAL...
Hi,My uC (STM32F30K6T6) is full in RAM memory.To optimize the RAM size, I have planned to reduce the Heap Size Memory (initial Heap size is 0x400).I do not use any manual memory allocation so, I think I will set it to a quarter of it (0x100), just in...
Hi, I’m having trouble reading measurements from the ADXL345 using SPI. I’ve attached a picture from the debugger that shows a view of the variables. The SPI is configured as master full duplex, and I’ve included a screenshot showing the SPI configu...
i recently made a custom board using stm32h743VIT6 and i configured lwip and freertos (before this i was using stm32f407vgt6 it is perfectly working and the circuit is same for this MCUs) now when i start the program it keeps having hardfault i tried...
Hello everyone,Today I'm writing to you because I'm trying to implement a PPPoS connection over the USB CDC Host of a STM32H745. The modem I'm trying to connect to is a SIM7500 of SimCom.I managed to establish the connection between the modem and the...
