Hello,I have a project with FreeRTOS and LWIP (plus some other stuff). I ran into the problem, that if I set the optimization for my project (-O3 in my case) I get weird communication glitches. For example I only get a reply every 3rd or 4th ping, Pi...
Hello,I got the lwIP raw TCP working on my H743ZI2 NUCLEO which I'm quite proud of, but it's quite slow. Now I would like to assign more memory to the stack. By default it's running with 16KB heap I think. So the first thing I did was changing the MP...
In CubeF4 v1.21, OTG_HFIR is set in USB_InitFSLSPClkSel() to either USBx_HOST->HFIR = 48000U;or USBx_HOST->HFIR = 6000U;which according to the RMs is incorrect, as they should be set to value one less.This has been already noted by @tsuneo her...
Hello Dear DevelopersI don't know what is the procedure, but when a file is added to the project, the compiler no matter if it is Keil, STM32cubeide, or IAR, does a complete rebuild while LWIP is added to the project. What should I do or What I can d...
Hi, I'm trying to follow this tutorial :- https://youtu.be/Hk--a4K497M -- demonstrating how to transmit simple string to PC via usb virtual com port. Unfortunately, I'm getting no output on my serial port. During debugging, I found that CDC_Transmit_...
I have installed STM32CubeIDE on Ubuntu 20.04 and set a project for NUCLEO L552ZE-Q, i want to try examples of STM32L5, and found that it need STM32CubeL5. How to install it ?
I use the HAL library function to transmit the wake up command to its I2C address.#define I2C_ADDRESS 0xC0HAL_I2C_Master_Transmit(&hi2c1, I2C_ADDRESS, 0x00, 4, 1000)but my code always return HAL_ERROR and the chip never acknowledges. I'm fairly new t...
Hi I have a project where I have a ST32L433Vx 100 pin 256K memory and 64K ram. I am using a display and as I need a lot of memory I have to upgrade. I am looking for a drop in chip and found the STML452VETx which is 512K and 160K ram. I looked at th...
HelloI'm going to use BLE to make a Bluetooth speaker that is connected to a cell phone.As far as I know, I need to use I2S to use audio output, is there an MCU that supports BLE and I2S communication?And can I know an example or something to refer t...
We have a system with STM32L431CCU which gets its initial firmware through serial download (as described in AN3155). We use USART1 and applied pattern 6 as described in AN2606. The software on the host side (embedded linux system) is either stm32fla...
