Posted on February 13, 2018 at 11:35Hi, just nitpicking here but still...The RM0394 (reference manual for STM32L4xxx) has a bad table of content, the entries go like this: 1, 2, 3, 4, 5, then restart 1, 2, 3, 4, 5, 6, 7, 8, then finally 1 2 3 ... as it should.

I need to know the Gm value of the STM32F446RC to determine the correct HSE crystal I can use with it.

When I try and debug my program using CubeIDE 1.6.1 there are no LPTIMx_OR registers shown in the SFR LPTIMx register blocks. Am I doing something wrong or is this broken in the debugging environment? Using SMT32Cube MCU Package L4 1.17.0.TIA Pete

Hey! I've been struggling to understand TouchGFX engine. I tried Discovery board and examples provided by TouchGFX Designer - everything works out of the box. However playing with high level app software on discovery boards won't help me on the product boards, so I tried build project from scratch and failed. After that I reduced my task to pick small I2C B/W display, working LCD driver and draw a square on it with TouchGFX framework. Just to see that engine "ticks" as expected. Still no luck. Things I tried so far:follow https://support.touchgfx.com scenario on SPI interfaceNUCLEO-G071 board examplesome guy's blog who was able to run TouchGFX with SPI displaywithout/with RTOSMaybe anyone saw EXACT steps on how connect TouchGFX framework to hardware. Like what signals/interrupts framework needs, which file to put it (ex. step 1: you should provide this instruction here for this and this flag there for that). I guess I'm talking about "Touch AL" layer which seems to be the hardest part.

Thank you for helping.There are 10 buttons.I am changing the value of the text when I press the button.10,20,30,40,50,60,70,80,90,100There are 10 patterns of, but the text is as follows only in the case of 60 and 70.? 0Other than that, the numerical value is displayed normally.The following code is written in the handler when the button is pressed.dimmerValue = 60;Unicode :: snprintf (textDimmerBuffer, TEXTCOUNTER_SIZE, "% d", dimmerValue);textDimmer.invalidate ();Why?Thank you.

I am using TouchGFX Designer v 4.16.1, first I use the GUI template for board STM32F769 Discovery as startup. By default it set my color depth to 16 bpp. But I want to examine other color depth however under Config-> Display -> Color Depth, it only give me one option i.e. 16 bpp. Why? From datasheet, the hardware should support other color depth. What should I do to change my color depth?

It appears to be a 2's complement left justified value. But making it simple, how do I convert this data... say for a start:au8_l_Data[0] is the low byte returned from the MEMS (OUT_X_L)au8_l_Data[1] is the high byte returned from the MEMS (OUT_X_H)Then in my code:    u16_l_Temp = (uint16_t)au8_l_Data[0];u16_l_Temp += ((uint16_t)au8_l_Data[1] << 8);Until here all is ok... but now how do I simply convert this unsigned 16 bit value (u16_l_Temp) into a 16 bit signed value? Simply casting this value to a int16 shouldn't do it if it is a 2's complement... or am I misunderstanding something?Thanks Phil

I have added the USB device via the CubeMX within STM32CubeIDE, however it have not automatically add the MX_USB_DEVICE_Init() function call at the main function. Do I have to enable something for this ? Or I'll have to manually add them myself?

I'm trying to decide between the ST25R3911B or the ST25R3916? I realize the ST25R3916 is newer; but newer does not always equal better. Are there any advantages to developing with the ST25R3911B? Primary purpose is to read 15683 transponders in a sometimes wet environment. Looking for a read range of 10cm

I am using SPC5 Studio ver 6.0 for a dev kit with freegcc with vle support for a SPC58NG-DISP dev kit and I want to add .srec file generation. I didn't see anything in the properties/c/c++ build/settings that was an easy selection and hope you can point me to what I need to do. Have an .srec parser and was hoping to reuse to not have to create an .elf parser or .hex parser.

Hello,I am using an STM32F103RB MCU in a specific Hardware design.The Hardware was always working fine (it is a final product of medical customer) until I flashed a software which implements the stop mode (deep sleep mode) management (by setting the SLEEPDEEP bit in the System control register (SCB_SCR) and configuring the PWR_CR register).Here is the code:void PWR_EnterStopMode (uint8_t stopEntry) { // Disable Systick Interrupt kSysTick->CTRL &= ~SYSTICK_CTRL_TICKINT_MSK;   // clear Power down deepsleep kPWR->CR &= ~PWR_CR_PDDS_MSK; // Select stop mode kPWR->CR |= PWR_CR_LPDS_MSK; // Clear wake up flag kPWR->CR |= PWR_CR_CWUF_MSK;   // Set sleep deep in ARM Cortex System control register kSCB->SCR |= SCB_SCR_SLEEPDEEP_MSK;   if(stopEntry == PWR_LOWPOWER_ENTRY_WFI) { // Request wait for wakeup interrupt __WFI(); } else { // Request wait for wakeup event __WFE(); } /* Reset SLEEPDEEP bit of Cortex System Co

Hello, I'm trying to develop an AVAS application, I have the AEK-MCU-C1MLIT1, the AEK-AUD-D903V1 and the AEK-CON-C1D9031 connection board. I've tested the Engine Sound Simulation and diagnostics with connection board and it woks, I get the sound out of the amplifier. However, when I try to change the audio files for ones of my own, I can't get any sound out of it. I proceed exactly as told in the instructions: I put the WAV files into the source folder (after checking they aren't bigger than 768kB), modify the sounddb.s file so it can access my WAV files, compile it, copy the .hex file from the build folder to the source folder and rename it, search for the 020000040100 string that identifies the beginning of the sound partition, delete everything behind that string, modify again the sounddb.s file so it doesn't compile the audio again, and then compile. It flashes without error into the MCU, but then it just doesn't sound. Could anyone help with that?Thanks in advance

Hi,I"m starting new project with brushless motor and I would like to connect two encoders (Rotary and Linear) with 3 hall affects and current measurement.I would like to check which ST controller "strong "enough for the applicationfollowing the parameters of the motorPWM to the phases shall be ~100kHZMotor speed up to 10000RPMRotary incremental encoder of 4096 pulseIncremental Linear encoder resolution ~5umAccording to above parameters I need 2 inputs for Rotary encoder at ~700kHz, 2 addition inputs for linear encoder and 3 PWM outputs of 100kHz.I need to close PID for speed and position loopback with very high resolution, and run SPI communication to the main controller at 10Mb/s.I have strict restrictions of the pcb size and I have to choose smallest controller.I have two questions: Can I use STSPIN32F0A controller with embedded Cortex-M0 MCU or it better to use STM32F4 controllers line? Does anyone run this component at dual encoder mode?How can I know which controller can support 4

There are many options for choosing the timing constant for RMS when using FFT. How to choose the right one? Why is the purpose of the timing constant for RMS? Please advise. Thanks!

The RF password can only be set over RF, I2C has no ability to access these registers (RF_PWD_0/1/2/3). If an RF user sets a password, and then forgets it, is there any built in mechanism to reset the password back to its factory default, or some other way to recover the password?

Hi, Can the time domain output of FFT calculation from MotionSP be speed (mm/s RMS), not acceleration on Y-axis? Please advise. Thanks!

@Ons KOOLI​. ​Hi, i want to use stm32f103 or stm32f1 family microcontroller for mass storage in usb for data logging.any reference and example are pretty useful as i am new to usb logging with stm32.​

I'm having some trouble getting an accurate PWM signal from my H743ZI Nucleo board (MB1364C). It is off by about 1%. I am not using an external crystal, I am using the MCO signal from the F723 chip on the same board. Am I just misconfiguring something? Or is the MCO signal not accurate? I need to generate a 1 ms pulse every 128 ms.I appreciate any help or suggestions!#include "main.h"   #define time_sync_Pin GPIO_PIN_0 #define time_sync_GPIO_Port GPIOB   TIM_HandleTypeDef htim3; void Error_Handler(void); void sysclk_config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; RCC_PeriphCLKInitTypeDef PeriphClkInitStruct = {0};   /** Supply configuration update enable */ HAL_PWREx_ConfigSupply(PWR_LDO_SUPPLY); /** Configure the main internal regulator output voltage */ __HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE1);   while(!__HAL_PWR_GET_FLAG(PWR_FLAG_VOSRDY)) {} /** Initializes the RCC Oscillators

Basically, I'm hoping to try out a different Microphone on SAI_2 and it looks like those pins would be freed up by removing the LCD display.
