hi I used the code in this link https://github.com/MYaqoobEmbedded/STM32-Tutorials/tree/master/Tutorial%2024%20-%20NRF24L01%20Radio%20Transceiverfor communicating with nrf24l01 with stm32 and it worked fine but I wanted to rewrite it in register leve...

hi, I bought a new blue pill board and tried to program it. this stm32has 64 kb flash and 20 kb of ram but the flash programming algorithm option in the Keil debugger don't have the 64 kb option for stm32f10x so I tried to change the flash size to 64...

I want to design a GPS car tracker that alarms when the speed reaches a certain value and I want to first test the code with the USB to TTL module which is connected to my stm32, and simulate sim808 answers. when I send the GPS information only the f...

I successfully used a HAL code I found on Github for driving an ili9341 TFT LCD with SPI then I rewrote the code with registers. Part of my code works and I am able to fill pixels with color but when I try to use a function named ILI9341_Draw_Colour_...

Hi, I successfully used a HAL library to drive a TFT ili9341 LCD and tried drawing a line on the LCD by touching the LCD and the code was perfectly accurate then I rewrote the code with registers. the touch is not accurate now and when I touch the LC...

thanks for your answer I tried using strsep but my compiler doesn't recognize it although I added string. h header probably because this function is new. I tried defining p as volatile but it didn't change anything.

while I was searching for examples of sscanf for strings with "," I couldn't find one but I came across another function for tokenizing the string which worked but after the second time I send the GPS info the micro hangs and when I debugged it was b...

I defined a dummy variable a and wrote a++ betweenTP_CLK_PORT->BRR=TP_CLK_PIN; and if ((TP_MISO_PORT->IDR&TP_MISO_PIN)!=0)It works fine now! my problem is solved. I think the reason it didn't work well was that I was violating the 200ns tCH spec base...

my problem is solved! I changed the BURST_MAX_SIZE value from 500 to 100 and the function worked! I'm still curious that what was the reason behind the hard fault i attached an image of the hard fault error of the debugger.

you don't have to read it all just read the general-purpose input-output section on page 170 I agree it is a bit confusing at first. but as you write codes and practice it becomes easier you can use this site for Keil configuration http://www.ocfrea...

Re: I'm about to start embedded programming and have an STM32f103C8T6 ARM-Coretex-M3 board to get started with. I'm also a C++ programmer and want to use that language to program a project to blink the LED of that board as my first embedded task.
