To put it another way, when would I want to use STM32CubeMX over STM32CubeF3/F4/F7 when working with F3/F4/F7 Discovery boards?

Hi, I wanna use the lowest power mode possible for my stm32l432kc. I want MCU to wakeup on accelerometer motion (which is possible since the accel generate interrupt on motion). I've read in MCU appnopte AN4621(page 13) that i2c is detected only in stop mode and that it generate a wakeup on i2c address detection (if I understand it correctly). But as I explained this is not what I want. I wonder if I can use shutdown or standby?

Hello,I have built LED blinky test program in SPC560B-DIS eval, I am setting and clearing LEDs in eval bord. I have introduced delay "osalThreadDelayMilliseconds(500);" between set and clear.I have used below code for my application, but it throws build error please find attached build error. Please guide to fix the error, Note if I am commenting line "stm_lld_start(&STMD1,stm0_config);" starts working. but if including throws build error#include "components.h"#include "stm_lld_cfg.h"int main(void){componentsInit();/* Enable Interrupts */ irqIsrEnable(); /* Activates STM0 Driver */ stm_lld_start(&STMD1,stm0_config); /* Enable channels and start global counter */ stm_lld_enable(&STMD1);for (;;){pal_lld_setpad(PORT_C, PIN_GPIO34_LED);osalThreadDelayMilliseconds(500); // Delay 500 mspal_lld_clearpad(PORT_C, PIN_GPIO34_LED);osalThreadDelayMilliseconds(500); // Delay 500 ms}}

I wonder if a ST25DV64K can be used in standalone.If I connect AC0 and AC1 to an antenna (using a smartag antenna), shouldn't the Harvest (V_EH) pin potential be around 3.3V (compared to the GND).Does the EEPROM configured to provide this power voltage by default?Thanks

I am working on STM32F779NI-EVAL board. I've tried the following QSPI example of stm32f769-eval board on STM32F779NI "..\en.stm32cubef7\STM32Cube_FW_F7_V1.14.0\Projects\STM32F769I_EVAL\Examples\QSPI\QSPI_ExecuteInPlace"I'm facing an error in QSPI_WriteEnable(). HAL_QSPI_Command() call in the function times out.However, with the same initialization sequence, the following example works perfectly on the same board."..\en.stm32cubef7\STM32Cube_FW_F7_V1.14.0\Projects\STM32F769I_EVAL\Examples\QSPI\QSPI_ReadWrite_DMA"While debugging the issue, I found that status register for QSPI was not getting set as expected (QSPIHandle->Instance.SR).Please share any pointers on the above issue. Thank you.

I have a LIS3DH sensor and Unico 7 in my computer and I am using the evaluation board MKI109V3. The thing is that I want to save the temperature data (measured by the Embedded Temperature sensor inside the LIS3DH) in a log file and with Unico this is only possible for Accelerations, LSB, interruptions and angles. It is not possible to save also Temperature? How can I do it? If not, how do you recommend me measure and save this data?

I'm trying to run AES CCM encryption on STM32F746G-Disco board in hw-accelerated mode. Tried to use CryptoLib 3.1.2 and low level Examples from 756-Eval board. For some reason there is no working example supplied by ST that implements this mode with HW acceleration on 746. CryptoLib works good, but only in FW mode (unaccelerated). Having tried to adapt HAL example (\Examples\CRYP\CRYP_AES_CCM) from 756 board, I encounter timeout in HAL_CRYPEx_AESCCM_Encrypt() call.Is CRYP supposed to work in this mode in 746NG at all? Ref man does not tell it shouldn't. Can anybody point me to what should be adjusted for it to work, compared to 756?Thank you!Vladimir

I have a problem with the operation of the I2C interface on stm32f103.

I am having a strange problem with FreeRTOS in CubeMX, I cannot get multiple tasks to work concurrently. I use the following procedure -Pre: Check STM32Cube_FW is fresh   (v1.9.0 used)Open STM32Cube V1.0   (v5.0.0 used)New Project -> 'Access To MCU Selector'MCU -> 'STM32F091RC' -> 'Start Project' (sel STM32F091RCTx)SYS: Timebase Source - TIM17FreeRTOS: EnabledAdd Task: myTask02 with defaultsGenerate CodeFor the example above myTask02 fires but the defaultTask does not, what am I missing to get both working? This has always worked for me before, what is wrong now?

Hi,i am trying to implement my mcu (stm32f407IG) as a composite device with USB FS. I want to use CDC+HID or more how can i implement that with CubeMX ?Are there any examples about that?Thanks for your help.

Hello,I would like to use a lot from the ST32L4R9I-DISCO Demo Code for my own application.Are you planning to release the source code?Thanks and best regards,Christoph

Hello,I'm a complete beginner of TouchGFX as I've just started exploring what it's got under the hood. I'm rather perplexed as to how I can access an element of a given screen from a container of said screen. Let me elaborate. In the main screen, I've two containers C1 and C2. One (C1) that's invisible by default and that I'd like to render visible from a button click of C2. How can I accomplish that simply ? I'm sure it's straightforward but I don't know which function I've got to use for that. Note that both containers are statically loaded.Thanks in advance

Hello, I am debugging a board which contains the MCU - STM32L4R7VI6 and an HYPERRAM IC connected to the OCTOSPI2 port on the MCU. While generating code on the STM32CUBEMX the tool generates the following code snippet at the bottom of the OCTOSPI_INIT function. sMemMappedCfg.TimeOutActivation = HAL_OSPI_TIMEOUT_COUNTER_DISABLE; sMemMappedCfg.TimeOutPeriod = 1; if (HAL_OSPI_MemoryMapped(&hospi2, &sMemMappedCfg) != HAL_OK) { Error_Handler(); }HAL_OSPI_MemoryMapped should not be initialized here and will execute the Error_Handler() 10/10 times since the sMemMappedCfg array isn't fullfilled at this point. It should be initalized in the main function according to the AN5050 OCTOSPI application PDF when the OCTOSPI2 port have been set to MemoryMapped. This is done in the main() function before HAL_OSPI_MemoryMapped () is called. So every time I generate code using the CubeMX tool I have to delete the snippet of code in the OCTOSPI_init() function. I found another issue where the

I have the FS bits set for +/-100g scale.The accel data is a 12-bit signed value, meaning each bit represents 0.049g.The threshold registers however is only a 7-bit value. From what I understand, this is to be an unsigned magnitude level, representing 0 to full scale. So, each bit represents 0.781g?My issue is that when I get interrupts and read the data, sometimes the levels are below the threshold. For example:Threshold register set to 3 = 3*0.781 = 2.344gAn interrupt occurs and the maximum accel (on any 1 axis) register value is 37. Which is 37*0.049 = 1.813g?Just hoping for some confirmation that I'm understand these values correctly.Thank you for any input.

Hello,I am using a F413ZHTx Controller on a custom board. I am logging data onto the SD card using SDIO interface. Since I am logging a lot of data, I created a code to:1) Open the file on the SD card2) Log 100 entries3) Close the SD card file4) Reopen the file.5) Using f_lseek move to the last location and try appending data. However, this is still resulting in data being overwritten every 100 entries instead on appending. Here is my source code: FRESULT fr; uint testbyte;   if(f_mount(&myFATFS, "0:" , 1) == FR_OK) { // open_append(&myFILE0, "log.csv"); f_open(&myFILE0, "log.csv", FA_WRITE | FA_OPEN_APPEND); }   count = preload_count; HAL_CAN_ActivateNotification(&hcan1, CAN_IT_RX_FIFO0_MSG_PENDING); HAL_CAN_Start(&hcan1); CAN_Filter_IDList(ID_00, ID_01, 0, 0, ENABLE); // CAN_Filter_IDList(ID_02, ID_03, 0, 0, ENABLE); // CAN_Filter_IDList(ID_04, ID_05, 0, 0, ENABLE); // CAN_Filter_IDList(ID_06, ID_07, 0, 0, ENABLE); // CAN_Filter_IDList(ID_08,

For example, to have the first few bytes of a single SPI transaction come from / go to a particular location, with subsequent bytes coming from / going to another location.

Hi... I'm trying to update the contents of a textArea from a freeRTOS task but I have a problem on the second iteration... it seems that the new text is written on top of the old ones... even if I call the Invalidate() methods as reported below:void Screen1View::setMessage(char* message, int msglen){textArea1.invalidate();Unicode::strncpy(textArea1Buffer, message, msglen);textArea1.setWildcard(textArea1Buffer);textArea1.resizeToCurrentText();textArea1.invalidate();}why is this happening ? shouldnt invalidate() do all the magics ? thanks a lot, Giampaolo

I have to design an NFC Antenna that has to stay on PCB whic shape is a circular sector.I'm thinking to design an antenna that follows the profile of the PCB.Is that a good idea? Do you have any other suggestions?Thanks

Hello,Currently i am using NUCLEO-F767ZI  as a development board for my application. As part of project requirement i have to explore NFC. I have gone through the specifications of X-NUCLEO-NFC01A1. This board is using Arduino UNO R3 connector. But NUCLEO-F767ZI board is using Arduino™ Uno V3. Can i interface X-NUCLEO-NFC01A1 with NUCLEO-F767ZI as a expansion board. I request your help in understanding this.Thanks,J. Sekhar

I am currently receiving a Tag EPC number and wondering how the CRC -16 value is generated so that I can check on reception. Following an Ack command I Receive 16 bytes in the fifo register which are read out as: 0x30, 0x00, 0xE2, 0x00, 0x42, 0x16, 0xCB, 0x60, 0x60, 0x15, 0x00,0x95, 0x1E, 0xD6, 0xB9, 0x1F. The Tag EPC number is: 0xE2, 0x00, 0x42, 0x16, 0xCB, 0x60, 0x60, 0x15, 0x00,0x95, 0x1E, 0xD6.Am I correct to assume the last 2 bytes are the CRC-16, how do we arrive at these numbers?

Hello,I searched in cubemx where to change the default value of gpio pins, but couldn't find it.Does anyone knows ? In generated code, all output gpio are set to 0, for example :HAL_GPIO_WritePin(GPIOK, SW_LED1_Pin, GPIO_PIN_RESET);Thanks,ranran

Posted on April 05, 2018 at 12:22Hi,I'm trying make USB custom HID with stm32f302CB. I'm using Keil v5.23 and STM32CubeMX. The problem: PC just don't recognize the USB, when i running in debug mode i saw something strange. Just after calling HAL_PCD_Init interrupt executing. In HAL_PCD_IRQHandler from there we go to HAL_PCD_ResetCallback. Thet calbek must config USB_EP0R register to config default endpoint. It perform by HAL_PCD_EP_Open. Ther are macros PCD_SET_EPTYPE thet write in USB_EPnR  but in peripheral viewer they doesnt change. It's strange because others USB registers are writing normally. I'm trying write UART_EP0R by my own but it's doesn't work either. In RCC_APB1ENR USBEN is set.Im trying to create same USB HID on STM32F407 Discovery with Keil and CubeMX and it works fine. Does someone have an idea where the problem could be?
