Hi allI have used CubeMx to create an FMC interface to psram(nonmultiplex) 8-bit data 10-bit addressThe data is valid on the rising edge of the fourth clock To have correct data on the data pins the pointer to write data (psram64) must be a 64-bit po...
Dear all,I am using lwIP over STM32F4 and I would add REST API to my project.I try to understand how to do that, and the only way that I have found is to use CGI. The problem is the reply: I can reply only with a static file present in the SDCARD (th...
Hi, I have a problem. I want to store 262144 (256KB) bytes of data in a buffer from the integrated ADC on STM32H723ZG. However it fails when the buffer is too large. I started at an buffer size of 4096 elements (uint8_t) and doubled until 65536 where...

Hello everyone, I use the button to hold the Semaphore in this task, when I press the button the Semaphore is released, but the error I get is that the button is not pressed but the Semaphore is automatically releasedplsss help me, thank so much
I am writing my own context switcher. I have a couple LED blink tasks for testing. It works fine when the tasks don't call any functions. Everything is inline. But when I include some function calls in the tasks and I get a context switch while in on...
Hello,I'm trying to interface to the FTDI FT2232H chip in FT245 Style asynchronous FIFO Mode to get a higher throughput over USB without needing to mess with the USB stack. I'm looking to get around 5MB/s throughput ultimately. Planning to use asynch...
Using STM32G0 with zephyr on a board that has motion sensor, flow sensor, Quectel BG770 modem and Quectel FC41D modem. Modem power is controlled by the switch which is being turned off for sleep and various other peripherals are also being disabled b...
To implement Ethernet communication on the STM32F746 Nucleo board where the Hercules software acts as a TCP server, and the STM32 board (acting as a TCP client) sends a string to control an LED on PB7, same as off string send server recevie the clien...
Hi, I'm trying to transmit Ethernet frame received by STM32H7[0] (passed this packet via serial) to STM32H7[1] to output on STM32H7[1] Ethernet. Ethernet packets input and output operates well if I act just with single controller, but looks like Ethe...
