Our app is based on a cross platform framework that uses phone-gap. we understand you provide some st nfc libraries that does this, but we would like to know the actual android/ios api used for this. please help.

New board STM32MP157A-DK1 bought, trying to connect. First, ST-LINK drivers were updated, then on-board ST-LINK version was updated to last available V2J26M36. MDK cannot connect ("No target connected"), st-link utility cannot see board ("Detection fail"). Through some experiments, by the moment, assume this:- Oscilloscope shows signals on SWDIO, SWCLK, NRST.- Tried all available firmware versions (V32...V36) from the site.- Wires were soldered to TP3, TP5, etc. to got connection to external ST-link. Initially, external ST-LINK/V2 had version M28 and MDK has read ident from the device! But MDK cannot flashing board ("invalid ROM table"), and firmware in external ST-LINK were updated. Since this, it came to the situation "No target connected" which was with the on-board st-Link. Another firmware versions were tried with the same result.ST-LINK/V2 and ST-LINK/V2 Isol were tried.In MDK dialog, internal st-link version shows as V2x36x26, but there NO such format in RN0093 doc. Only J36M26

I have two hardware boards mount with STM32H750 . I want to set the GPIO G11 to high , the code as below :  __HAL_RCC_GPIOG_CLK_ENABLE();   HAL_GPIO_WritePin(GPIOG, GPIO_PIN_11, GPIO_PIN_SET);    GPIO_InitStruct.Pin    = GPIO_PIN_11;   GPIO_InitStruct.Mode   = GPIO_MODE_OUTPUT_PP;   GPIO_InitStruct.Pull   = GPIO_PULLUP;   GPIO_InitStruct.Speed   = GPIO_SPEED_FREQ_LOW;  HAL_GPIO_Init(GPIOG, &GPIO_InitStruct);One board work but another don't . The corresponding bit on the "GPIO input data register" on failure board will not set after i run the above codes. Any idea ?Thanks

Hi everyone, I'm trying to capture a PWM signal's duty cycle and period using a timer (TIM3 in this case) in PWM input mode. However, when I run the following code, I see no updates in the CCR1 and CCR2 registers, which should have the values of my duty cycle and frequency respectively. Any help would be appreciated!/** register manipulation with the PWM Input References: manual RM0091 (the STM32 F0 manual), STM32F042x4 STM32F042x6 Datasheet, and UM1956 (the nucleo board) **/   #include <stm32f042x6.h> #include <timerdrv.h>       void TIM3_PWM_InputInit();   int main(){   TIM1_PWM_Init(); TIM3_PWM_InputInit();   while(1){   } }   void TIM3_PWM_InputInit(){ // setting up GPIO for PWM input mode RCC->AHBENR |= RCC_AHBENR_GPIOBEN   // set pin PB4 in alternate function mode GPIOB->MODER |= GPIO_MODER_MODER4_1;   // set pin PB4 to AF1 for TIM1 CH1 GPIOB->AFR[0] |= (0x1UL << GPIO_AFRL_AFRL4_Pos); &nbs

Hi, I want to receive 32 bit data from a SPI master but in the cubemx options there are only two options available, 8 bits and 16 bits, so what if I want to receive 32 bits frames, what should I do?Thanks

I want to flash my Nucleo Board from STM32CubeIDE. When I click debug in the IDE it fails with:ST-Link enumeration failed   Error in initializing ST-LINK device. Reason: ST-LINK DLL error.st-info --probe saysFound 0 stlink programmersWhen I enumerate the USB devices connected to my computer I don't see the board.I have the board connected via the USB port on the ST-LINK part of the board. The board powers up fine and runs the pre-loaded blink code. The ST-LINK LED is flashing red.I have tried 2 Nucleo boards (F4339ZI and F303K8). I have tried 4 USB cables. I have tried with and without a USB hub and multiple ports. I have tried with 2 computers and 2 OSs (OS X and Linux).Am I right in thinking the ST-LINK should show up as a USB device without me needing to do anything else? Presumably nothing else will work till I can solve this problem.This is my first use of these boards so user error is highly likely. Any docs I could find seemed to gloss over this step.

Even though I configure the RCC to use an external high speed crystal as a clock source (HSE), the HSI remains selected even after the SystemClock_Config routine is executed!! (I have checked the HSE pins and it appears that the clock driver (PH0/PH1) is not turned on.)The SystemClock_Config code generated is:void SystemClock_Config(void){  RCC_OscInitTypeDef RCC_OscInitStruct = {0};  RCC_ClkInitTypeDef RCC_ClkInitStruct = {0};  RCC_PeriphCLKInitTypeDef PeriphClkInitStruct = {0};  /** Configure LSE Drive Capability   */  HAL_PWR_EnableBkUpAccess();  /** Configure the main internal regulator output voltage   */  __HAL_RCC_PWR_CLK_ENABLE();  __HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE3);  /** Initializes the CPU, AHB and APB busses clocks   */  RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE;  RCC_OscInitStruct.HSEState = RCC_HSE_ON;  RCC_OscInitStruct.PLL.PLLState = RCC_PL

Hi,We're using a STM32MP157C on a custom board and trying to get ethernet over USB to work. We have a type B USB connector on the board and when a cable is connected, the USB peripheral seems to get suspended as the logs from dwc2 shows. We've seen that there are patches for forcing sessions to be valid and added "force-b-session-valid" to the DT node. Yet the only thing we see when we connect is the suspend interrupts firing. Any ideas what's going wrong here?Thanks

Hi,not sure if I am missing something obvious here:https://github.com/STMicroelectronics/logicanalyserI cloned the sources and imported everything into CubeIDE, however it does not see any make targets, when I try to build how2eldb's main.c I get:**** Build of configuration Debug for project how2eldb ****     Nothing to build for project how2eldbI can build other M4 examples just fine, so it does not seem to be a general setup issue with my IDE. Any hints on how to proceed?I am using STM32CubeIDE version 1.3.0 Build: 5720_20200220_1053 (UTC) on Linux with an STM32MP157A-EV1 board.Kind regards,Jin

For a hour I'm breaking my head. How it this possible? What's going here?unsigned max_prio = 5; __set_BASEPRI(max_prio); __DSB(); __ISB(); uint32_t basep = __get_BASEPRI(); printf("basepri=%u\n", basep); //>>>>>>>>>>>> it prints 0 !  Using the Atollic IDE, if this matters.

I am new to using PWM, so not sure if this is a bug, invalid default settings or wrong documentation.I configured my project using STM32CubeMX.I'm using the internal clock, and the default setting for PRESCALER is 0. I can see in Keil using the debugger that the CNT register is counting (random value appears on each refresh), but the PWM output on the actual MCU output only updates when I update the RELOAD register. However, if I change the PRESCALER to 1, it works. Hardware documentation says that the prescaler can be set in the range 1-65536, implying that you should subtract one in order to fit this into the 16bit sized registry.Is the actual valid range 1-65535? If so, should STM32CubeMX change it's default value, and flag 0 as an invalid value?

HelloI am considering using STM32F769NI.Can all GPIO pins measure analog voltage when set to input?Thank you.

is there any documentation out there that tells how much power is being consume when the bluetooth operates?and if the power consumption is affected whether the Device is running on RUN mode or STANDBY mode.If there are any tips that can make reduce the power consumption without sacrificing too much performance

Hi,I have a STM32L476RG board and I try to execute the following program, obtained from this web http://www.microdigitaled.com/ARM/STM_ARM/Code/Ver1/Chapter02/Program2-1.txt which is for a different Nucleo 64 board (STM32F446RE)/* p2_5.c Toggle Green LED (LD2) on STM32F446RE Nucleo64 board at 1 Hz * * This program toggles LD2 for 0.5 second ON and 0.5 second OFF. * It is identical to Program 2-2 but was written without using * the header file.

Posted on July 02, 2018 at 11:00Hello,I am using an STM32F042 controller. I have to send a wake-up pattern followed immediately by 5 bytes (@10400 baud) from my device. Wakeup pattern: 25msec LOW followed by 25msec HIGH5 byte sequence: 0xC1, 0x11, 0xF1, 0x81, 0x44I tried the following: 1) I configured the GPIOA, Pin 10, created a delay function and sent the Wakeup pattern. However, I am facing difficulties reconfiguring the GPIO into the USART Mode on the fly and then transmitting the 5-byte sequence.GPIO_ResetBits(GPIOA, GPIO_Pin_10); delay_nMSEC(25); GPIO_SetBits(GPIOA, GPIO_Pin_10); delay_nMSEC(25); usart1_init(10400);USART_SendData(USART1, 0xC1); while(((USART1->ISR & USART_ISR_TXE) && (USART1->ISR & USART_ISR_TC)) == 0){}The above code does not work. I get the wakeup pattern correctly and then a single pulse of roughly 5msec after that. But no 0xC1. However, if I put theUSART_SendData(USART1, 0xC1);in a while(1) loop, I get data transmission correc

There is the macro __FILE__ to know the complete path of the source code but how to estract only the project name of CubeWorkspace ?I would like to display this on my develop phase to be sure of the version running.On Arduino Due I have used this code but with STM32 is not easy:void display_Running_Sketch (void) { String the_path = __FILE__; String the_date = __DATE__; String the_time = __TIME__; String ver; int slash_loc = the_path.lastIndexOf('\\'); String the_cpp_name = the_path.substring(slash_loc+1); int dot_loc = the_cpp_name.lastIndexOf('.'); String the_sketchname = the_cpp_name.substring(0, dot_loc);   ver = the_sketchname + " " + the_date + " " + the_time;   myGLCD.setFont((unsigned char *)SmallFont); myGLCD.setColor(255, 255, 255); myGLCD.print((const char *)ver.c_str(), CENTER, 1);   delay(1000);   myGLCD.print((char *)" ", CENTER, 1); }

I'm trying to perform signal filtering with STM32F407VGT. I've set up the ADC and DAC to work synchronously, triggered by a timer at 42kHz, and using DMA. The idea is to process half of the buffer while ADC is filling the other half. However, even without any processing, I'm getting a periodic noise in my signal(picture attached). Seems like some portion of the buffer is always messed up. Why is this happening and how can I fix it? I'm also attaching the relevant sections of my code here. Both ADC and DAC operate in 12bit mode and are triggered by Timer2. Both use DMA in circular mode.#define DATASIZE 64 #define FULLBUFFSIZE 128   uint32_t adc_val[FULLBUFFSIZE]; uint32_t dac_val[FULLBUFFSIZE]; static volatile uint32_t* inbuffPtr; static volatile uint32_t* outbuffPtr;   void process_DSP() { for (int n=0; n<DATASIZE; n++) { outbuffPtr[n] = inbuffPtr[n]; } } void HAL_ADC_ConvHalfCpltCallback(ADC_HandleTypeDef* hadc) { inbuffPtr = &adc_val[0]; outbuffPtr = &

I wanted to use the CAN Legacy Driver like i did it in my old STM32F103 Project (Same Cube Version. latest Firmware) but i failed.I copied the Legacy CAN-Module to the Driver Source-Path, the Legacy Include's were already included.But what should i do now? In the old Project i only enabled the Legacy Driver in the HAL_conf.h, but this Fails with the STM32F042.What is the way to enable it here, or is there anywhere a good example how to ust Interrupt Receive with the new Driver??
