Do you know why do I get this error at this line : #define return_status(gps_data,st) (gps_data)->status = st;return st;
Here is what the compiler says :
../Core/Src/gps_parser_lib.c:87:59: error: 'gps_data' is a pointer; did you mean to use '->'?
87 | #define return_status(gps_data,st) (gps_data)->status = st;return st;

I am looking at the IIR filter with direct form-2 programming with live sensor data. As I see, RTOS is used in the code to filter live sensor data.
Is it possible to do it without RTOS, by using timers and interrupts? My existing project is based on a non-RTOS code, and I'd like to know how to IIR filter ADC data in the same firmware without RTOS.

Hello all,
I'm from Embedded Systems Bare-Metal Ethernet Programming course. In topic "Developing HTTP Ethernet Applications -> Programming Detecting Link Change", I found that problem about clock configuring may cause application display message "Cable connected" even if it's not connect. Then, I try to configure and debug about clock configuration but problem still occur.

Can you suggest me...

Embedded Systems Bare-Metal Ethernet programming lacks the last lesson, do you have an expected date tu update it?? I use this subcategory because the Embedded Systems Bare-Metal Ethernet programming doesn't exists

I am using the STM32F767ZI microcontroller and was able to implement a webserver with an HTML/CSS/Javascript formatted webpage that can perform GCI commands and use SSI as well. The issue is that the webpage doesn't stay alive after roughly 30 seconds and after issuing a few CGI commands, the webpage fails to load and the server ultimately stops responding. I tried enabling the LWIP_HTTPD_SUPPORT_11_KEEPALIVE macro in my lwipopts.h file, but no behavioral change. I also tried to up the MEM_ALIGNMENT, MEM_SIZE and PBUF_POOL_SIZE, but still seeing the webpage lose connection over wireshark (see attached). What options do I have and what can l look into to solve the issue? Thanks!

In Programming: Implementing the CDC TX Device, after installing Termite 3.4, I don't understand what is the "USB Serial Device (COM5)" device that you had connected on the Bluetooth & other devices window? Why I did not get it after installing Termite 3.4?

I am using a Nucleo F446RE board. When I attempt to configure the debugger (I have installed the drivers from here: https://www.st.com/en/development-tools/stsw-link009.html#overview). When I create a project and go to the debugger settings, uVision 6 simply crashes.

Any tips on how to debug/resolve? Thank you.

Hi, I am currently following this course. I am confused right now as why we are giving buffer length to

height*width/8 . I know why we are multiplying by height and width as that is the display height and width but what is purpose of dividing by 8 ? Is this for number of pages? but still I dont understand its concept.

Embedded System IoT Systems Design is also incomplete, by when it will be completed?

Thanks

How or where are the resources and code for "4G LTE IoT: Bare-Metal to HTTP, MQTT, SMS"? It is referenced verbally, but I cannot locate where it is at.

Here are the first set of topics - which one is supposed to have the resources:
Introduction

Introduction to 4G LTE and IoT (7:36)

Tools and Resources Needed

Overview of the NUCLEO-F411 Development Board (1:47)

Course Overvi...

Thonny V4.0.2 will not program the STM32F411 and when I disconnect "Thonny" the code stops.
When I start "Tera-Term V4.106 SBN#9298" it does not display the text.

Have you experienced this same problem

How much time takes to answer or solve a ticket?, regards

As same as in the lesson video, I noticed that exists a few seconds delay between the moment when the micro starts (RESET) and the notification on the terminal, mainly in the disconnected situation
Can you explain why? I think it's interesting to know how lwip stack works
