Solved

Hello All...I posted this in the MCU section and got no response so I figured I would ask here.I am new to ST Micro tools and have never used them. My background has been hardware and I have been 'hacking' at code on MSP430FR for a good 10 years. I am used to Code Composer Studio and writing register level C code. This is a complete IDE with compiler, debugger, etc all wrapped up in one, free from TI.I am interested in the new STM32WLE IC's for an upcoming prj.  My question is if I download just the CubeIDE and the CubeProgrammer is this enough to write, compile, link and debug on the STM32WLE? Also for flashing / debugging hardware is the STLINK-V3SET the correct tool?thank you

After an update from cubeMX 6.0.1 to 6.1.0 the user labels have disappeared in pinOut view. Only the function per pin is displayed. Is there an option to make either the user label or the pin function visible?

STM32CubeMX 6.2.0STM32CubeH7 1.9.0STM32H735IGI found a minor bug configuring the ETH section for the STM32H735 in Cube MX. The default RAM adresses for the descriptors and the RX buffer are 0x30040060, 0x30040000 and 0x30040200 which are in the "Reserved" area on this chip series. To change this value to 0x30000000 and onward, checking needs to be disabled on these input fields.In the LwIP section, the value for LWIP_RAM_HEAP_POINTER in the Key Options section also has a wrong default value, but it can be changed without disabling checking.Default values in ETH section Memory map from RM0468 Default values in LWIP sectionEdit: added captions to images

Requesting "VDAC1_OUT2 Channel" on ADC IN18 causes the .ioc file to generate the following line:- sConfig.Channel = ADC_CHANNEL_DAC1CH2_ADC2;which doesn't compile, I think it should be:- sConfig.Channel = ADC_CHANNEL_DAC1CH2;

I followed the Tutorial for the QR Code. It works when you draw just one custom widget. But when i add the same custom widget serveral times in the same Screen or in a custom Container, the code is not able to draw all the custom widgets, it seems that the draw function is interrupted and my QR Code it's not complete. Maybe something about the HAL? Any suggestion?I add my example project in 4.16. Thanks!

The private variable "FLASH_ProcessTypeDef pFlash" in stm32h7xx_hal_flash.c is used in some functions I notice that it is not initialize by any function.So for example the first time a call is made to: FLASH_Program(uint32_t TypeProgram, uint32_t FlashAddress, uint32_t DataAddress)the result of the line is  __HAL_LOCK(&pFlash); is undefined. So it will only work by chance on the first call, successive calls are granted to succeed as  __HAL_UNLOCK(&pFlash); has been called

Good afternoon, I'm trying to use STM32F746ZGTx LQFTP144 for a railway scoreboard.(Commuter train schedule) I have a problem. I ran a BSD project on the Nucleo-144 STM32F746 board from the STM32746G_DISCOVERY examples. I commented out everything except the LCD. Display_Demo Description() Using the oscilloscope, I found that the following outputs of the controller are active.PD9PG12 LCD_B1PG15PG0PD0PD1PH0 OSCPF2PH1 OSCPE4 LCD_B0PA14 SWPE14 LCD_CLKPF13 PD10 LCD_B3PD15PE7PE8PF4PF5PD8This list does not match the description of stm32f745ie. pdf and CubeMX. I hope you can help me figure out which controller pins are actually used to control the LCD. Sincerely, Alexander.

Hi,I found several issues and want to contribute. Please share the ultra light wight API source code for the VL53L1X.Thanks!

Hello,On a STM32L4 design, we no longer have an SWD connection to the processor: using STM32CubeProgrammer reports ST-LINK SN : 39FF6A064243383912381057ST-LINK FW : V2J36S7Voltage : 3.26VSWD freq : 4000 KHzConnect mode: NormalReset mode : Software resetDevice ID : 0x461UPLOADING OPTION BYTES DATA ...Bank : 0x00Address : 0x40022020Size : 20 BytesBank : 0x01Address : 0x40022044Size : 16 BytesUPLOADING ...Size : 1024 BytesAddress : 0x8000000Read progress:Error: Data read failedSWD works fine in the design in general, also also ran on this particular device. An idea what is missing?Or to put it the other way round: what do we need for a running SWD? Supply, connection to the SWD pins of course, but what further? IMHO we don't need running CPU core or clocking on it for example....Thank youRalph

Is the only difference between the two that LSM6DSOX has the machine-learning core (MLC)?In other words, are the 2 parts interchangeable when the MLC is not used?

Hi thereI am planning to use EVAL6498L to build a boost dc-dc converter with synchronous rectification. I notice that if I fit two TO-220 switches these will be very close, therefore I am not sure what heat-sink I can use, as mechanical space becomes a problem if I use this heatsink (RA-T2X-51E), which I was planning to use. Would you have some recommended type of heatsinks that can be used for TO-220 switches sitting on this EVAL6498L board? Thank youLello

On X-NUCLEO-GFX01M1 I would need to manage the on-screen keyboard because LCD is not touch.I have successfully ported keyboard example from designer to hardware (X-NUCLEO-GFX01M1 on NUCLEO-G071).Is it possible to add support for the keypad or is it better to write a new one?If so, what do you think?

Good afternoon,Maybe is an obvious question.I'm studying the default startup_stm32g030xx.s, a part of the syntax is figured out in the program manual of MCU and another part in the GNU AS command page.But, for example, those following commands: .syntax unified .cpu cortex-m0 .fpu softvfp .thumbI can understand the meaning but I would like to know in which ST's document are described, which are the options, etc. Thank you in advance, Riccardo C.

Can someone help me figuring out how do we conclude the obtain pcm values are accurate and can there be any references to validate it and test it back?Any suggestions please help?

We're using the STM32 Nucleo-L4R5ZIThe issue is that whenever we try to check the ST-Link using STM32Cube Programmer or ST-Link Utility, it won't connect to the board.We kept getting errors like"STLink USB Communication Error""No STM32 Target Found"In STM32Cube Programmer, we got the error "st-link error (dev_usb_comm_err)" and "st-link error (dev_connect_err)"Whenever I connect in the board through USB, the ST-Link LED is red, I'm guessing that means something is not working properlyWe've tried using different USB cables and USB ports on different computers, we tried uninstalling STM32 related programs, reinstalled them, and updating drivers, but nothing seemed to help.When looking at "NODE L4R5ZI", there's a text file named FAIL.txt, with text saying "The interface firmware FAILED TO reset/halt the target MCU". 

I put the following question in the General forum of STM32, only today I saw the specific forum for questions related to Digital Power. Anyway..I'm builing a photovoltaic power application using the F334R8, but i'm having issues with HRTIM1, TIMERA/TIMERB output. Attached are scope outputs.CH1 the main power switch Drain-Source voltage, CH2 is the signal comming from the STM32F334R8 HRTIMA (or B) - which drives CH1; CH3 is the output of the high voltage side of the inverter (TIMC/TIMD) and CH4 is the current through an active clamp converter - synched with CH1...The problem is: The output from TIMA/TIMB can sometimes randomly gets higher than 100%! (as shown on CH2).HRTIMA/B configuration seems to be correct - also i'm enabling shadow registers - and the code to extract those waveforms are running an open-loop soft-start duty increase *** only ***....It's very weird and very random, so the question is: what should I check on the STM32 side? code? hw? power-sources?BTW:Code to update th

In the STM32F4 Reference Manual, there is an example calculation of the WWDG timeout period t_WWDG (see attached image).However when I type in the numbers from the example, I get a different value (87.38 ms instead of 21.85 ms). It seems that the value was calculated with WDGTB[1:0] set to 1 instead of 3.Can someone confirm that this is correct?

I am studying USB PD. I am using the demo board B-G474E-DPOW1 and the project from the STM32CubeG4 examples. When I connect the USB-C cable to the charger, after the ATTACH event, I receive a list of possible profiles from Source. But when the cable is already connected to the charger and I reset the board, then after the ATTACH event, the list of profiles from Source does not come. Is this normal behavior? Should source power profiles come only after cable connection?How can I fix it so that after resetting the board, everything works same as on cable connection?

Hello. Im using STM32L476RG nucleo. Im trying to debug bare metal code. Sadly my debug stops working when it gets to line where MODER register is configured. Console says following: Target is not responding, retrying...It keeps saying that until debugger loses connection.The line where debuggur loses connection: GPIOA->MODER = 0x400;However when i write same line with OR debugger is fine: GPIOA->MODER |= 0x400; As soon as i remove OR(|) it crashes. The problem is with OR it won't change register values and my code won't work. Any solution?#include "stm32l4xx.h" // Device header   void delayMs(int delay);   int main(void) { RCC->AHB2ENR |= 1; // enable GPIOA clock, 00000000000000000000000000000001   GPIOA->MODER = 0x400; // set PA5 as output, 0b 0000 0000 0000 0000 0000 0100 0000 0000, default value //0xABFFF7FF?   while(1){   GPIOA->ODR = 0x20; // set PA5 output data register 1, 0b .... 0010 0000 delayMs(100); GPIOA->ODR &=~ 0x20;

Attached please is the connected equipment, installed software and the error message.

I successfully used a HAL code I found on Github for driving an ili9341 TFT LCD with SPI then I rewrote the code with registers. Part of my code works and I am able to fill pixels with color but when I try to use a function named ILI9341_Draw_Colour_Burst the code doesn't work. I tried to use the Keil debugger to see what happens and it showed a hard fault occurred. The function code is shown belowvoid ILI9341_Draw_Colour_Burst(uint16_t Colour, uint32_t Size) { //SENDS COLOUR uint32_t Buffer_Size = 0; if((Size*2) < BURST_MAX_SIZE) { Buffer_Size = Size; } else { Buffer_Size = BURST_MAX_SIZE; } LCD_DC_PORT->BSRR |= LCD_DC_PIN; LCD_CS_PORT->BRR |= LCD_CS_PIN;   unsigned char chifted = Colour>>8;; unsigned char burst_buffer[Buffer_Size]; for(uint32_t j = 0; j < Buffer_Size; j+=2) { burst_buffer[j] = chifted; burst_buffer[j+1] = Colour; }   uint32_t Sending_Size = Size*2; uint32_t Sending_in_Block = Sending_Size/Buffer_Size; uint32_t Remainder_from_block

Hi,I am developing a bootloader and an application for a device. Now I have two separate projects and I configure all pins using CubeMX twice. Each project has ist own .ioc file and it is very much work to synch all pins and other settings between the two projects, also because the CubeMX tool is very slow.So I wonder if there is an elegant way to share a .ioc config between both projects without breaking things?Thanks in advance,Anguel
