How can I fix that "fatal error: portmacro.h: No such file or directory"
1) I added portmacro.h in the folder (\Middlewares\Third_Party\FreeRTOS\org\Source\portable\GCC\ARM_CM4F)2) I added path for the header file (MCU GCC Compiler > Include paths)

Methods of debugging when MCU operations require real-time operaton
Hi. I am testing some USB_FS communication between my PC and my STM32 board (specifically STM32756-EVAL). I am wondering what the most appropriate and standard debugging methods in STM32 are, in situations where the debugger cannot be used.The reason...
Encoder read error
Hi there!i start to work with a rotary encoder, i configurate a timer 3:in this way and i enable the interrupt . for read the encoder inside the timer interrupt i write nuber= (TIM3->CNT)>>2;so when i read the varible the first time i see 0 - 1- 2- 3...
Resolved! Powering STM32 Blue pill through external source via micro USB
Hello, I've a strange problem and I can't find the answer on internet.I'm transmitting a data from UART2 of my STM32 Blue pill. Its just one line :- HAL_UART_Transmit(&huart2, (uint8_t*)Tx_msg, sizeof(Tx_msg), 100);While using with ST-Link, it works....
Resolved! SDIO/EMMC version of STM32 versus EMMC IC version
Hi I want to use an EMMC( INSIGNIS NSEC53K) with STM32F405 SDIO interface. STM32F405 manual says: "Full compliance wit MhultiMediaCard System Specification Version 4.2."the EMMCwe have chosen: INSIGNIS NSEC53K. Its datasheet says:"Compliant with eMMC...
How to send 10-bit message using HAL_SPI_TRANSMIT
I am trying to interface with an AD8400 single channel digital potentiometer. It communicates over SPI and requires 2 address bits and 8 data bits to set its resistance. I am having trouble figuring out how to send a 10-bit message.I have set the dat...
ADC reading on STM32H7B0 CPUs
Hi!I am having problems reading accurate values using the STM32H7B0 CPU. I have identical boards with STM32H7A3 and STM32H7B0 CPUs and the results from the B0 boards are off by a lot. I have also tried to run the ADC in 12 vs 16 bit mode and the scal...
I am using STM32F407G Discovery1 board and I have problem with the debug
I am using STM32F407G Discovery1 board. I'm printing Hello world and I want to debug to see the string. I do debug configuration: I set debug probe ST-LINK GDB server, i check SWD like interface and enable SWV with core clock 16MHz but still I don't ...
Resolved! How to Trigger DMA from a TIM with HAL
Hi,I am trying to have a DMA move one unit of data every time the timer finishes it's counting period. The DMA would be circular so it would continually do this. I am going to be moving from a buffer to the CCR register of a pwm output. I saw a HA...
Resolved! Which LSE Crystal to use on Discovery Board
I have an STM32L100C-DISCO board (MB110B Rev. B) and I want to install the LSE crystal, which is not populated by default. I consulted the schematic in the UM1656 "user manual for the 32L100CDISCOVERY discovery kit". Crystal X3 has a part number of...
