I'm having trouble using ADC with DMA. It is working correct, I'm getting the correct result. But DMA is corrupting another data which is not related with DMA in runtime. I'm also using Ethernet, because of it, I can not disable D-Cache.I do my Ethernet, DMA, MPU configurations according to the following article (without RTOS)https://community.st.com/s/article/How-to-create-project-for-STM32H7-with-Ethernet-and-LwIP-stack-workingAnd also I readhttps://community.st.com/s/article/FAQ-DMA-is-not-working-on-STM32H7-devicesBut like I say, I do not want to disable d-cache.I use example in STM32Cube repository to use ADC with DMA:void HAL_ADC_ConvHalfCpltCallback(ADC_HandleTypeDef* hadc) { if(hadc == &hadc1) { /* Invalidate Data Cache to get the updated content of the SRAM on the first half of the ADC converted data buffer: 32 bytes */ SCB_InvalidateDCache_by_Addr((uint32_t *) &adc1.m_rawResult[0], 7); } if(hadc == &hadc3) { /* Invalidate Data Cache to get the updated c

Hello,I installed a SBSFU for a custom application on a Nucleo-H753ZI board. Everything works fine, however with the current settings of the SBSFU, my application is lacking RAM to handle the large inputs I want it to handle.I used the memory mapping of the UserApp example application. After further investigation, I observed that the application RAM was located in the DTCMRAM area (0x20000000 / 128KB). Unfortunately, this area seems to be too small to host my application which RAM used to be in the RAM_D1 area of the board (0x24000000 / 512KB).Therefore, I would like to know how I could move the application RAM area from the DTCMRAM area to the RAM_D1 area.I tried the following:Modify the RAM section of the mapping_sbsfu.ld file as follows:/* RAM section */ /* SE RAM1 region protected by firewall */ /* SE stack is placed 1st in RAM, stack overflow does not write on other RAM area */ __ICFEDIT_SE_region_RAM_start__ = 0x24000000; __ICFEDIT_SE_region_RAM_stack_top__ = 0x24000400; __ICFEDI

HiI must have done something wrong in the function below to transmit a buffer on a tcp socket. If transmitting up to 4096 bytes the function works fine. If len is greater than that, nx_tcp_socket_send fails. How to stream a buffer correctly using Netx?void TCP_Send(void *buf, uint32_t len){ UINT ret; NX_PACKET *send_packet;nx_packet_allocate(&AppPool,&send_packet,NX_TCP_PACKET,NX_WAIT_FOREVER);  nx_packet_data_append(send_packet,buf,len,&AppPool,NX_WAIT_FOREVER);ret = nx_tcp_socket_send(&TCPSocket, send_packet, NX_WAIT_FOREVER);if(ret) nx_packet_release(send_packet);}

Hello All,I'm trying to receive tag ID through st25r3916 discovery board. I read out the register through PC GUI software tool and try to mimic it on my firmware. I'm new to this board even RFID. I did not find any library that can help to develop my application. Please, let me know if you know any library that I can use. I'm using yocto linux on NXP.Thank you

Hi,Readings from my VL6180X sensor are very unstable. They vary about +-8 mm from measure to measure.I tried with Nucleo board and official api, and also with Arduino board and Sparkfun code. 2,8V power supply is from linear regulator, measured object is solid white at distance 50 mm.I tried to supply it from battery instead of usb, nothing helps.

Hi I want to use the continues mode feature, so I can read and write from the buffer simultaneously. I have trued to find an example, do you have anything that help?

I see the ADC Pin runs to the STM32 MCU ADC Pin, and that in the firmware demos it prints the adc value to the screen.However I don't see any place the ADC value is used for tuning or anything else other than just random information.For example, for reflected power for tuning, it just uses the I/Q values and has nothing to do with the ADC.How can I use the ADC reading to my advantage? I see that in the Eval that the T2 Input is "Coupled" with the input to the Log Detect Chip. So it seems the Log Detect just helps verify my Tx power is on and perhaps give me some "number" to go along with it.Is it for testing that Modulator control register 3  values for TX_lev is taking effect? Is the ST25RU3993 actually going to Tx a smaller amplitude into a fixed voltage PA? :)Thanks for any knowledge you can share!

S'agissant de la dernière question et selon le guide (version 4.0 de juin 2017) des exigences applicables aux substances contenues dans des articles, je cherche à savoir si lors de son incorporation dans l'article, la composition de la substance ou du mélange chimique déclaré pouvait changer (sous l'effet d'évaporation, de transformation, etc.) ce qui pourrait permettre de recalculer sa concentration (m/m).

I have managed to use the CubeProgrammer_API.dll in a visual studio C# project. Everything seems to be working properly but when I try to set the verbosity level nothing changes. It seems to be fixed to level 2. This is the code I'm using:[DllImport("CubeProgrammer_API.dll", CallingConvention = CallingConvention.Cdecl, EntryPoint = "setVerbosityLevel")] internal static extern void setVerbosityLevel([MarshalAs(UnmanagedType.I4)] int level);   */ And the C# function: /* public static void setVerbosityLevel(cubeProgrammerVerbosityLevel level) { NativeMethods.setVerbosityLevel((int)level); }Thanks in advance!

On Nucleo H753ZI normally PG7 is used as USB FS overcurrent indication input and has a red LED on it.I need PG7 as output (don't ask why) going to external connector. Not using the USB FS function.So when PG7 is set low, the overcurrent LED glows.Can this cause any damage to the pin or USB FS circuitry?

RM0455, rev. 6, says reset state of SYSCFG_PMCR is 0x0F00 0000.But STM32H7A3ZIT6Q, rev. Z, shows 0x0300 0000 instead, i.e. PC2 and PC3 switches closed. not open. Does this depend on package as PC2 and PC3 are not bonded out for this particular package?

I am looking for a way to change the HAL I2C lib clock speed during runtime to either 100k or 400k or 1M.I tried the following.....hi2c1.Init.ClockSpeed = 100000;However when compiling this the compiler do not recognize the parameter.

Hi - I have a Nucleo-F746ZG that I am configuring in CubeMX (version 6.2.1). When configuring it I am trying to only set up the RTC and UART3. UART3 is set up to print to the USB virtual COM port (and that works fine).In CubeMX, once I start a new project, I go to the "Timers" tab, the to the "RTC" node, then select the checkbox for "Activate Clock Source."The only changes I made to the generated source code were in the main method. I understand from reading the source code for stm32f7xx_hal_rtc.c that it is important to call HAL_RTC_GetTime and then call HAL_RTC_GetDate.Inside of main, in USER CODE BEGIN 2:RTC_TimeTypeDef current_time; RTC_DateTypeDef current_date; HAL_RTC_GetTime(&hrtc, &current_time, RTC_FORMAT_BIN); HAL_RTC_GetDate(&hrtc, &current_date, RTC_FORMAT_BIN); printf(" H:M:S = %02d:%02d:%02d\r\n", current_time.Hours, current_time.Minutes, current_time.Seconds); HAL_Delay(2000); printf(" H:M:S = %02d:%02d:%02d\r\n", current_time.Hours, current_time.Minute

I have a motor with delta windings and in initial testing with MCSDK it doesn't seem to work. Looking at the current feedback on a scope and it looks awful compared to a similar wye winding motor on-hand with similar specs.Before investing more time into the issue I want to verify that MCSDK should work fine with delta windingsHardware:STM32F446RE nucleo boardX-NUCLEO-IHM07M1Both motors using 2048-count encoders for feedbackThanks in advance!

So let say I have a group of radio button like this:touchgfx::RadioButtonGroup<5> radioButtonGroup1;And whenever use select every radio button inside the group, I want to trigger the same callback handler.How can I achieve this? '

Hi everyone, just a question about this DMA not triggering for unknown reasons. The only thing I can deduced is the switch from C to C++ and how variables behave within an object maybe. All I know is the peripheral is working and the DMA is setting the right flag. I also tried the C version of my code and it worked. Double check the buffer is in the right memory region as well the RAM_D1.For some reason it doesnt wanna hit the void DMA1_Stream3_IRQHandler(). Yes I used the Main.cppint main () {   clock clock; audioProcessor ap; uart<uint8_t*> uart(ap.GET_UART4_RxBUFF(), 1);   while (1) {   } }   void DMA1_Stream3_IRQHandler() {   if (((DMA1->LISR) & (DMA_LISR_TCIF3)) != 0) { DMA1->LIFCR |= DMA_LIFCR_CTCIF3;   UART4_TC = OK; } }uart.h/* * i2s.h * * Created on: Jun. 22, 2021 * Author: Christopher */   #ifndef PERIPERHALS_HEADER_MIDCLASS_UART_H_ #define PERIPERHALS_HEADER_MIDCLASS_UART_H_ #include "peripheral.h"   &nbsp

Hello,can the ULINK2 debugger works in the STM32CubeIDE?In case, how the Debug Configuration has to be set?ThanksMaurizio

I use the standard function " STUHFL_T_RET_CODE Gen2_Lock(STUHFL_T_Gen2_Lock *lockData) " to Lock a Tag, But now I wanted to unlock the same Tag and following the standards information in Gen2 protocol Like the pictures below, I try using the same function but with a different "mask" but don't obtain a successful. Is It possible to Unlock a Tag? Can you send a Mask to Unlock all Fields in one Tag?Mask to Lock: FFFFFh.Mask to Unlock: FFC0h.https://www.gs1.org/sites/default/files/docs/epc/Gen2_Protocol_Standard.pdf 

Hello I designed a single sided Antenna now i recieved the PCB's soldered the ST25DV04K onto it, but my phone can't find the Tag. Is there a possibility without a network analyser to trobleshoot such a PCB/design?Or would is it better for troubleshooting try to reach the Tag with an X-NUCLEO-NFC05A1?I've added the design file from teh edesign suite.Thank you

Hi There,I'm looking for help with the SAI4 for this device. I have setup the DMA for SAI4A which is linked to BDMA Channel 2. I have defined my buffers within the D3 domain and have enabled the event on the BDMA channel to request number 15 (sai4_a from the reference manual) I still get a transfer error upon starting the DMA transfer. I have watched the training videos on BDMA,DMA and the DMAMUX, but I still think I am missing a step.I am also having a similar issue on the TIM23_CH2 using DMA but I think if I can find my error on the SAI4 it will be a similar solution for the Timer.Kind regards,Kline
