In function USB_EP0_OutStart is: if (dma == 1U) {   USBx_OUTEP(0U)->DOEPDMA = (uint32_t)psetup;   /* EP enable */   USBx_OUTEP(0U)->DOEPCTL |= USB_OTG_DOEPCTL_EPENA | USB_OTG_DOEPCTL_USBAEP; }In my opinion enabling endpoint should be out of DMA condition: if (dma == 1U) {   USBx_OUTEP(0U)->DOEPDMA = (uint32_t)psetup; } /* EP enable */ USBx_OUTEP(0U)->DOEPCTL |= USB_OTG_DOEPCTL_EPENA | USB_OTG_DOEPCTL_USBAEP;STM32CubeF4 version 1.24.1The same situation exists in STM32CubeF7.

Hi, I am making some test in low power mode using the end_node example for LoRa but I always get 0.5mA in sleep mode, I use the STM32CubeExpansion_LRWAN_V1.2.1 version and I am doing measurements in the JP3 VDD_MCU_LRA branchI have read this post where @Remco Groenendaal​ recommend us this:To get to the lowest power consumption mode using the B072, one should:1.- be absolutely sure TCXO is not connected to vdd but connected to PA12 (vdd_tcxo)  I have changed JP9 to pins 1-2 but is the sameand in the same post @Kevin Genskowsky​ told us this:Finaly solve it ,Conected VDD_TCX0 to PA10and changed ,mlm32l0xx_hw_conf.h ♯ define RADIO_TCXO_VCC_PORT GPIOA , ♯ define RADIO_TCXO_VCC_PIN GPIO_PIN_10And worked imidiatly PA12 might have some extra configuration that is missing.So this is very confuse because I don't know if is necessary to change the control pin of TCXO or the solution is just change the position of JP9, or both2.- set all your defined (and unused) pins to anal

The autotuning algorithm implemented in the app reader, is an external routine? I mean, the IC ST25RU3993 by itself can not tune an antenna. I guess that we need to implement some algorithm making a sweep and checking the reflected power, and then finally set the 3 values for the tunning capacitors.

Product folder on st.com and databrief says "The STSW-STM32080 package contains all binaries and source code for DfuSe USB device firmware upgrade (DFU) software, including the demonstration, debugging GUIs, and protocol layers." Same is also mentioned in the readme.txt in the package.I downloaded the package but could not find the sources in downloaded file. So, where are they?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.

Subject says it all, really: Go here, download the ZIP file for the 'Manufacturing files', and the 'Mechanical' folder is empty :(Looking to get the offsets of the holes from the Arduino connector so I can bolt it down well.

Hi.Based on the OTA example, I created an application. The only difference is the use of MTU = 256.The length of the characteristic is equal to MTU android pixel (126)The problem is that when sending firmware from a custom application to an Android Pixel, all packages very rarely arrive. A lot is lost.At the same time, when testing on Android Nexus 7, all packages come.At first, I decided that a Pixel transmits data faster than a Nexus and reduced the transmission speed by delay. Only a delay of 100ms between the transfer of packets allowed to receive all packets.But at the Nexus, packets are transmitted approximately every 20ms and everything comes.Then I limited the length of the characteristic to 20 bytes and nothing changed, when transferring from a Pixel, data is lost.The next step, on the chip side, I removed the code that writes to the flash and bingo!, with a characteristic length of 126, without using the delay, all the data comes.Question to the respected community and STM en

Editing an IOC in CubeMX IDE and using Pin & Configuration view, changing a pin's special-function or user label does not mark the IOC as changed. Consequently File Save remains grayed-out and it is not possible to save the changes.@Markus GIRDLAND​ - Please confirm you can reproduce this and a ticket has been opened, Thanks!Best Regards, DavePS: IOC attached illustrates the problem.STM32CubeIDE, Version: 1.0.2, Build: 3566_20190716-0927Try changing pin PA4

We are planning to use three L7987 DC/DC switching regulators on our interface module. All L7987 should be synchronized and should operate with the same frequency set with an external resistor on the pin FSW.In datasheet https://www.st.com/resource/en/datasheet/l7987.pdf (chapter 4.1, page 13) it is mentioned that the same resistor on pin FSW should be used for multiple L7987. It says: “In case two or more (up to five) L7987 SYNCH pins are tied together, the L7987 IC with higher programmed switching frequency is typically the master device; however, the SYNCH circuit is also able to synchronize with a slightly lower external frequency, so the frequency pre-adjustment with the same resistor on the FSW pin, as suggested above, is required for a proper operation.�?So ,what does that mean? Should each L7987 should connected to one resistor with the same resistor value (R1=R2=R3=20kOhm) or should only one resistor R1=20kOhm connected to the pins FSW of the three L7897 ? NOTE: This

I need a network connection for my project. Does the network PHY have to be programmed in CM4 via LwIP ... or does communication via OpenAMP to the CA7 work? Are there examples of a simple web server that can switch a port or similar? Thank you very much for your effort.

Hi ,  My name is Midhun .I want to know is it possible to read from multiple channels of same timer in input capture mode...?I am using Stm32f401RE Nucleo board ,Using MDK ver 5.0 on KEIL IDE.Our project includes a multitude of optical encoder units which we used to find the position of dc motors associated with it .Is it is possible to access multiple encoder unit reading which are connected to different channels of a particular timer ,If yes how to read value by addressing the timer channel specifically using the HAL API functions..?

I need to change all occurences of variable names. These names happen to be in a lot of .C and .H files hundred times. Source is from a collegue with "xz2b3" kinda variable names. I'd like to change variables to longer, more talkative names. Some IDE editors feature some Ctrl-Shift-F for this purpose. Any tip?

Does LIS2DH12 support hand raising detection,thx.

I'm trying to get the ADC to work with DMA Continuous Requests, and am not having any luck. I've actually seen it work once, totally randomly, but on subsequent runs all I get is a white screen on startup. I see the ADC is indeed still calling HAL_ADC_ConvCpltCallback and the buffer is updating , but it seems to break LCD functionality.I've tried setting ADC3 to Stream 1 instead of the default Stream 0, but that didn't help. I'm kind of at a loss as to what the actual issue is. Anyone with more experience know what might be happening?ADC3 settings: Clock Prescaler: PCLK2 divided by 4 Resolution: 12 bits Scan Conversion Mode: Enabled Continuous Conversion: Enabled DMA Continuous Request: Enabled Number of Conversions: 2Channel 4, Channel 5Stream: DMA2 Stream 1 Mode: Circular Data Width: WORDNVIC: ADC1/ADC2/ADC3 Global interrupts enabled

Hello,We are using FMC interface.Is it that the access must be in the same size of the memory data bus ?In software, the bus width is defined as following:MemoryDataWidth = FMC_NORSRAM_MEM_BUS_WIDTH_16; and the access is 16 bit as following:So, is it illegal to make the access in 32-bit if the data width is 16-bit ?Thank you!

Hello ST community,I have some troubles using Quad-SPI interface in STM32H7 micro.I need to communicate with a custom part using quad SPI mode (4 data lines). The interface is configured for indirect mode and DMA is enabled.In a super-simplified case I need to execute two transactions sequentially:1. Send address byte, send two dummy cycles and read back one byte.2. Read just one byte (no address, dummy cycles and instruction words)The first transaction works fine all the time.The second transaction failed in multiple ways. In different code variants, I was able to reproduce application crashes, or producing different than intended number of clock cycles during the bus transaction, or the completion interrupt is never fired.Minimal working example:uint8_t data_rx_ready = 0; uint8_t data_packet_rx[16];   void TestRead_QuadSPI() { QSPI_CommandTypeDef cmd; HAL_StatusTypeDef res;   // FIRST TRANSACTION: address byte, dummy byte (two cycles) and one data byte to read cmd.Add

I'm using a Nucleo-H437ZI2 board. Set up a simple project in STM32CubeIDE with the latest firmware for H7. I enabled both Icache and Dcache, no MPUI create a uint16_t array of 12,900 elements as a buffer for an ADC conversion using DMA transfer into the bus. Since the Dcache is active, after the ADC/DMA conversion completes, I want to invalidate the cache, to ensure coherency between what the DMA transferred and what the CPU sees. So, after having read all the available L1 documents (AN4839) and some examples, I added SCB_InvalidateDCache() right after the DMA completes, and before accessing the array. But the execution hangs, and if I interrupt the execution, I see that it loops forever in the code below in core_cm7.h__STATIC_INLINE void SCB_InvalidateDCache (void) { #if defined (__DCACHE_PRESENT) && (__DCACHE_PRESENT == 1U) uint32_t ccsidr; uint32_t sets; uint32_t ways;   SCB->CSSELR = 0U; /*(0U << 1U) | 0U;*/ /* Level 1 data cache */ __DSB();   ccsi

I have a "hello world" example that works fine on a STM32F765Z6T6 (custom board). It basically waits for a USB serial port to be opened on the host side, and outputs "Hello world" every second over and over again. Unfortunately it's based on libopencm3 and my own middleware library, so the code is not easy to share.So everything works fine on the STM32F765Z6T6.I designed another board using a device from the new value line - STM32F730R8T6 (schematics attached). Curiously, my hello world example doesn't work on this new board - it doesn't enumerate.I know the USB hardware works because I can program it using the DFU bootloader, and I know my code is being run because I can get a blink example to work, and it blinks at the correct frequency (crystal frequency is the same as the board that works). I verified with an oscilloscope that the blink frequency is correct, so I don't think it's a clock setup issue (I am using the same crystal as the working board, so all the clock setup should be

Hi all, I have downloaded the crypto lib directly from the "Help->Install New Software" menù of SPC5Studio , but I do not have any idea on how to use it, include it inside a project, use sample codes (if available), and so on.Proposed link:https://my.st.com/content/ccc/resource/technical/software/sw_development_suite/c3/77/6e/b9/23/14/43/42/SPC5-CRYPTO-LIB.zip/files/SPC5-CRYPTO-LIB.zip/jcr:content/translations/en.SPC5-CRYPTO-LIB.zipdoes not allow to download any library!!!Could anyone be so kind as to help me? Any suggestions would be very appreciated!!!Best regards,Andrea MocciEmbedded SE developer at Eldor s.p.a.

"Contains the word aligned CPU2 boot reset start address offset within the selected memoryarea by C2OPT"​SBRV sets CPU2 boot address, but I use STM32cubeProgrammer to get NUCLEO board data as follows:The starting address of CPU2 is 0x08032C00, but SFSA is 0xcb and the address is 0x080cb000. My understanding is that SFSA should be aligned with the starting address of CPU2. As the picture says:​SFSA--0x080FFFFF is a dedicated area belonging to M0+，So what does it mean to set SBRV to 32C00 !​
