However, semihosting can be extremely slow. Another good option is to output debug information over the serial port (UART). We can call the STM32 HAL functions (e.g. HAL_UART_Transmit), but sometimes it’s easier to use the standard C library functions printf, scanf, and so on. To do...
This article demonstrates how to implement an SNTP client using the LwIP stack in a callback-based application. The demonstration code is built using theNUCLEO-H723ZGdevelopment board but can be easily tailored to a different STM32. All implementation is done using theSTM32CubeIDE v1.16....
I use STM32L4P5RG with APS6404L-3SQR to develop GUI. I want use QSPI PSRAM as data memory for GUI. Now, I enable QSPI PSRAM as data memory as follows: 1.configure QSPI PSRAM , SPI with NVIC in CubeMX 2. add PSRAM (xrw) : ORIGIN = 0x70000000, LENGTH = 8M to LinkerScript.ld...
and ranges from 0 to DBL (DBLconfigured in TIMx_DCR). DBL This 5-bit vector defines the number of DMA transfers Example of how to use the DMA burst feature In this example the timer DMA burst feature is used to update the contents of the CCRx registers (x = 2, 3, 4) with the ...
This application note also gives an overview of the STM32 SSP solution with its associated tool ecosystem, and explains how to use it to protect OEM secrets during the CM product manufacturing stage. Refer also to: • AN4992 [1], which provides an overview of the secure firmware...
In my application ESP32C6 configured as a SPI slave and stm32 configured as a SPI master. My application is to receive the data from master(stm32) through spi protocol and send the received data to Wi-Fi through an UDP protocol. So I have created the two tasks one for spi and another...
The TCXO mode is defined by the STM32WL Nucleo BSP by selecting USE_BSP_DRIVER in Core/Inc/platform.h. If the user wants to update this value (no NUCLEO board compliant), or if the BSP is not present, the TXCO mode can be updated in radio_board_if.h. Default template v...
Debugging embedded systems can be frustrating at times. When debugging your embedded projects, won’t it be better if we can use C standard library functions likeprintf()? Many of us have same questions in mind i.e. How to use printf in keil uvision? or How to retarget printf for my ...
I am trying to write the data individually to single pages. In Case 1, I write data to the address 0x0000F000 and read the data using the same address. I get the correct data that I wrote. Later, I use Case 2 with the address 0x0000F040, and I read the data using ...
Summary This article provides a step-by-step guide on how to use the LwIP with the STM32H5 series. A simple DHCP connection is made using the
