Hi folks,currently I am working on an communication with a sensor via QuadSpi using the STM32F446 controller. The QuadSpi Bank1 was chosen, but unfortunately the hardware designer did not connect the Chip Select signal (CS) to the pin that corresponds to the QuadSpi Bank1 (according to the pinout is either PB6 or PG6) but to the pin PC7. Could this be a reason for the QSPI communication not to work? Indeed, it is not working (in the oscilloscope I only see the QSPI CLk signal but the data inputs remain low). The same code works in another board where the pins were correctly chosen according to the pinout. But I thought that this issue would not be meaningful (not to connect the CS signal to the right pin).Thanks a lot for your supportJorge

Hello, I am able to compile the M4 examples and it looks as though they run as expected ( I can see the log trace on the A7 side from the linux console). I would like to examine the log trace from the M4 side also as I would like to modify some of these examples for further use. In the OpenAMP_TTY_echo example (main.c) are the following lines  log_info("Cortex-M4 boot successful with STM32Cube FW version: v%ld.%ld.%ld \r\n",                                           ((HAL_GetHalVersion() >> 24) & 0x000000FF),                                          &nb

Hello.I was using CubeMX to configure an ADC and a comparator both with enabled interrupt. After the code generation I looked into the init functions but I could not find any interrupt configuration (priority setting and enabeling). In the HAL_COMP_START_IT function there is the starting of the interrupt. But not the priority setting.So my question is, where is the code generated by CubeMX which does set the interrupt priority? Or do I have to set that manually?best regards, Benjamin.

I'm using an STM32F769 for a project. I'm trying to continuously stream ADC samples to a buffer. I can fill the buffer without issue, but the DMA never recirculates back to the beginning. I don't get any DMA errors, and the ADC is still running (I can see the DR value change in the debugger if I halt).Any ideas? The DMA configuration is below.// Intermediate buffers for DMA streaming.static struct tag_sample_buffer { uint16_t samples[2][1024];} sampleBuffer[3]; DMA_InitTypeDef dmaInit; dmaInit.Direction = DMA_PERIPH_TO_MEMORY; dmaInit.PeriphInc = DMA_PINC_DISABLE; dmaInit.MemInc = DMA_MINC_ENABLE; dmaInit.PeriphDataAlignment = DMA_PDATAALIGN_HALFWORD; dmaInit.MemDataAlignment = DMA_MDATAALIGN_HALFWORD; dmaInit.Mode = DMA_CIRCULAR; dmaInit.Priority = DMA_PRIORITY_HIGH; dmaInit.FIFOMode = DMA_FIFOMODE_DISABLE; dmaInit.FIFOThreshold = DMA_FIFO_THRESHOLD_HALFFULL; dmaInit.MemBurst = DMA_MBURST_SINGLE; dmaInit.PeriphBurst = DMA_PBURST_SINGLE; hDma[0].Init = dmaInit; hDma[0].Instance = DMA2_

I have a small project that coded and prototyped on a 32F0308DISCOVERY board (STM32F030R8T6). It works perfectly on the Discovery board.I now want to switch over to using a STM32F030F4P6 programmed by the ST-Link that's on the Discovery board (CN2 jumpers removed). I made a new project in CubeMX with the new target (I am using Keil MDK5) and tried to flash the STM32F030F4P6, but had no success.So, I went to what I think is the bare minimum and simply tried to do a full erase of the chip using ST-Link Utility and STM32CubeProgrammer and I could not get that to work either.Here is what I have connected on the STM32F030F4P6:Pin1 (BOOT0) connected to Discovery GroundPin4 (NRST) connected to Discovery CN3 Pin5Pin5 (VDDA) connected to Pin16 (VDD) connected to Discovery 3voltsPin15 (VSS) connected to Discovery GroundPin19 (SWDIO) connected to Discovery CN3 Pin4Pin20 (SWCLK) connected to Discovery CN3 Pin2I also have Discovery CN3 Pin1 connected to 3volts.Both the ST-Link Utilit

STM32G070. It is said there are 4 USARTS in the datasheet. For USART3/4, there is no place talking about the clock source for them. Would you please tell us what's the clock source for the USART3/4?

How to install mono on my STM32MP157C-DK2?Thanks

Hi,I need to match motor speed with the speed of the measured device.My idea is to toggle pin when encoder pulses count reaches some value.I was unable to generate an interrupt on a specific count, so I decide to react on each pulse and check count.I use interrupt: HAL_TIM_IC_CaptureCallbackInterrupt body is quite simple:void HAL_TIM_IC_CaptureCallback(TIM_HandleTypeDef *htim) { count1= TIM1 -> CNT;   if ((TIM1 -> CNT) >=1000) { TIM1 -> CNT=0; } }But when I set a breakpoint on TIM1 -> CNT=0;I read from registry CNT and it's always more than 1000. I was expecting to be equal 1000 on interrupt.Perhaps I chose the wrong interrupt but it was the only one that I was able to fire on encoder work.Also when I'm checking CNT in main program loop I hit breakpoint on CNT larger than 2000. while(1) { counter = TIM1 ->CNT;   if (counter >= 2000) { counter =0; TIM1 -> CNT =0; } }I'm working now on True studio and I have a feeling that on AC6 it was wor

Does anybody know which silicon revision code is actually in production for the STM32H7 family?

I'm using STM32CubeMX 5.0.1 for creating projectsWhile configuring GPIO using configuration window the properties windows on the bottom of selected GPIO pin overrides the visibility of other GPIO pins at the bottom on configuration window It is not scrolling to view, but we need to select different operation to make all GPIO visibleI'm attaching the screen shots of GPIO Config window without Properties and with PropertiesIt would be better to make gpio config with scrolling to view the bottom GPIO while property window is open

Hi All,I am currently working on creating a file system on an stm32f207, using the nucleo board for the time being while I wait for my custom boards.The board will have an SD card as well as a USB. I have made a simple function for creating a folder onto a drive:FRESULT f_CreateFolder( const TCHAR* path){   FRESULT fr;   // Create folder/directory fr = f_mkdir(path); if(fr == FR_OK){   // Success // TODO: f_mkdir Something to happen when successful   } else{   // Error // TODO: f_CreateFolder make directory error   }   return fr; } // END f_CreateFolderthe "f_mdir" has no calls to which drive it is referring to, so if both SD and USB are mounted, how do I choose which drive to create a folder on??Finally, I have been succesful with creating a single folder on the SD (yet to try on USB but I can't imagine it being any different) but I am not sure how to create folders within folders, if that makes sense lol.This works to create folders

Hello,I understand that many STM32 support USB OTG, so they can be USB hosts.What if I want to connect more than one device? Can I connect a USB hub and control several devices at the same time?

Hello All,I have some CR95HF Antenna Design Queries1) what is actual difference between in performance of 424nH antenna and 1120nH antenna used in  M24L-DISCOVERY kit and NUCLEO-NFC03A1 respectively?2) In CR95HF-A demo Board Antenna impedance design guidelines document,  mentioned formula to calculate antenna inductance using frequency 13.56MHZthey have given Ra=0.5 Ohm and La=36.6 * w where w= 2 * pi * f so w= 2 * pi * 13.56 = 85.2  so as per calculation La= 36.6 * 85.2 = 3118.3 but they have give La= 430nH can you explain this ?3) In CR95HF chip datasheet I have read that ZOUT differential impedance between TX1 and TX2(1) 27 Ω and Small signal differential input resistance (Rx1/Rx2) 100 kΩ , what this actual means?Is this parameters taken in consideration without onboard mounting or with components?because PCB manufacturer considered it without mounting components.from above parameters TX1 and TX2 and (Rx1/Rx2) I have checked all matching circuit component in M24

Hello community,I created a Makefile with CubeMX and the X-CUBE-AI software. When I try to compile the project with arm-none-eabi-gcc the linker cannot find network_runtime.a./usr/lib/gcc/arm-none-eabi/5.4.1/../../../arm-none-eabi/bin/ld: cannot find -lnetwork_runtime.a collect2: error: ld returned 1 exit statusThe file network_runtime.a is in the folder Middlewares\ST\AI\AI\lib and the option -L/mnt/DiscoveryBoard/Middlewares/ST/AI/AI/lib/ (absolute path.., I also tried others...) is defined.Maybe somebody knows what I'm missing.Thank you very much.Oliver

Hi,I would like to know the maximum velocity that the TESEO LIV3F chip can still having a stable update rate. I'm currently doing localization using TESEO LIV3F, and it update the position very slow under 3m/s. Perhaps that's because there are some trees and buildings when I'm moving around , but even if I'm at open space (at least 20m away from the building), I am still not getting the position updated. Therefore, I would like to know the maximum velocity that can guarantee TESEO LIV3F to continuously update its position.Thanks

We have to qualify the STPS61L60CW as a 2nd source, but unfortunately in the datasheet we do not find any Information about repetitive surge current.Your diode is used in the freewheeling path of a trigger circuit for a power semiconductor. The trigger current is totally 200A, per diode (two per TO-247 case) we have a peak of around 100 A. However, the pulse duration is only a few microseconds and will be repeated with a maximum of 1 kHz. This is how the waveform looks like:We tested our system with your diode in our lab without problems. But just to be sure, do you confirm from your side that we do not take any thermal risks with these high current pulses? NOTE: This question and answer originated from a customer support case which was handled by us. We regularly review support cases and add any helpful ones here for all to benefit from.        

I want the STM32F769NI to generate an interrupt when a pause after a received byte on USART6 was detected. I am using CubeMX and configured USART6 for Asynchronous mode with 9600 baud and to enable global USART6 interrupts and use the low level drivers for USART6. In the source files I enabled the RXNE interrupt with LL_USART_EnableIT_RXNE(USART6). So far this is working, on Interrupt I can read the correct byte from USART_RDR of USART6.I want to get an Interrupt when a pause of 100 ms is detected after a byte was received. So I configured:LL_USART_SetRxTimeout(USART6, 960); LL_USART_ClearFlag_RTO(USART6); LL_USART_EnableIT_RTO(USART6);And tried to light a LED on the discovery board in the interrupt handler:void USART6_IRQHandler(void) { /* USER CODE BEGIN USART6_IRQn 0 */   // Byte received: if (LL_USART_IsActiveFlag_RXNE(USART6)) { serialHandleRXByte(LL_USART_ReceiveData8(USART6)); }   // RX inter-bxte timeout: else if (LL_USART_IsActiveFlag_RTO(USART6)) { LL_USAR

I'm building a CAN app with STM32CUBEMX and TrueStudio. I'm using interrupts so need to register my calback funcs. I put #define USE_HAL_CAN_REGISTER_CALLBACKS 1 at the top of main.h. The following line in my code:HAL_CAN_RegisterCallback(&hcan1, HAL_CAN_RX_FIFO0_MSG_PENDING_CB_ID, HAL_CAN_RxFIFO0MsgPendingCallback );is producing the error "HAL_CAN_RX_FIFO0_MSG_PENDING_CB_ID undeclared". But it is a value of the enum type HAL_CAN_CallbackIDTypeDef which is declared in stm32f4xx_hal_can.h which is included in main.h. I'm stumped.
