Mongoose not working with LWIP + FreeRTOS

 I'm trying to build a simple HTTP server using Mongoose with the LWIP IP stack on FreeRTOS CMSIS_V1. It is important that I let LWIP handle the network interface since I'm also using it to advertise a service using mDNS. This is what my task looks l...

Problems with HAL_UART_Transmit_DMA

I’m using the STM32F401RET6 board, collecting data from a USB accelerometer at 16 kHz.I wanted to verify that the data is actually being collected at 16 kHz, and then run an FFT to compare it with previously collected PC data. To do this, I need to t...

Resolved! Simple ISR for DMA

I'm losing my mind a little, because this seems like it should be a simple task. I have configured my I2C module to enable DMA and interrupts: I can confirm that my call to HAL_I2C_Master_Transmit_DMA returns OK. I can also confirm that the generate...

Resolved! STM32N6 DK ETH problem

I use STM32Cube FW_N6 V1.2.0 to create an FW to run a web server on the DK board. I figured out that I can not talk to the PHY chip to read the PHY ID. I compared the code with another example that ST released and figured out that these codes are mis...

DMA2D minimum width requirement?

Hello,I'm using a H743 with the DMA2D device in RegToMem mode.  Generally it seems to work for larger images, but I've been trying to fill a small rectangle (5 x 60) pixels, and I was expecting 300 write pulses.  Instead, I'm getting 480 pulses (8 x ...

CAN RX ring buffer interrupt

I am simulating messages to be received via CAN on the STM32F0xx series uC. The hardware FIFO does not overflow as I have activated the overflow interrupt and checked the FIFO level, which never exceeds 1. The current implementation consists of a 128...
