Resolved! PWM with DMA makes unwanted pulse stream

Hi,I want to make PWM stream with various duty, so I'm testing PWM with DMA using NUCLEO-G0B1RE and HAL library.The first image shows weird pulse train. I set DMA buffer with [duty 1] * 8 + [duty 17] * 8 + [duty 5] * 8, but oscilloscope captures eigh...

STM32F767 Ethernet at different rate

Hi everyone. I'm using stm32f767zi board with lwip stack and I need to transmit at different rate through Ethernet: 50mbit/s, 80mbit/s and 100mbit/s. When I tried to send a buffer of 6554 byte every 1ms (in order to send 6553600 byte aka 50mbit every...

I have an STM32H742VGT based project with ethernet connection (LAN8742AI-CZ phy ) the problem is that I get HAL_ERROR when the HAL_StatusTypeDef HAL_ETH_Transmit(ETH_HandleTypeDef *heth, ETH_TxPacketConfig *pTxConfig, uint32_t Timeout)

When the HAL_ETH_Transmit is called by the driver it seems the code below (part of HAL_ETH_Transmit ) times out as the DMA TX complete callback are not called. I've followed the STM32H743 example but I guess STM32H742 memory map is a bit different th...
