Hi,(running Mac OS Mojave 10.14.5)I can not debug my program, on stlink- gdb I get the following console message:STMicroelectronics ST-LINK GDB server.

I need to make a device that communicates (modbus) with a product that uses the rs232 protocol, with 7 bits and 2 stop bits. I use CubeMx and HAL libs. There is some process to do this. As is known in STM32, only have 8 and 9 bits in length.

Hi,I'm using STM32H743ZI and uVision 5.28.0.0.Traying to program the FLASH Bank 1 results in an error. The error is thrown by FLASH_WaitForLastOperation(). In SR1 the following bits are set:PGSERR1INCERR1Any Idea?RegardsJakob

hi I'm trying to write some code to read on i2c an as 4058b encoder with the HALL library with stm32, with arduino it works perfectly:Wire.beginTransmission (_slaveAdress);Wire.write (internal_register);Wire.endTransmission ();Wire.requestFrom (_slaveAddress, nbByte2Read);for (bytes i = 0; i <nbByte2Read; i ++) {readArray [i] = Wire.read ();}readValue = (((uint16_t) readArray [0]) << 6);readValue + = (readArray [1] & 0x3F);Could you have an equal reproduction of code with HALL i2c?thank you

HiI am evaluating the new STM32CubeIDE .When trying to create a new project (based on an existing project done using eclipse + GNU ARM Eclipse) i am encountering a problem when accessing the project properties to define include directories; Preprocessor defines, etc...When assessing "Project -> Properties -> C/C++ Build -> Settings" i am getting a "java.lang.NullPointerException". The error log is in the PostThe project was created as a new C project, I then copied to the folder the respective source code.

.i have compiled adc application from examples, i dont know how to import program to my spc56el70l5-disp kit using spc5-udestk.can any one help me or point me in right direction.

As for SPC56D-Discovery board, refer to page 5 of its application note AN4438, Getting started with SPC56D-Discovery board, it mentioned a test program calling "Test App SPC560D-DIS board.zip�?. Somehow I can't find it on ST's website. Where do I download this file? Thanks.

I have looked around in the GUI to see if it can be included anywhere, but I am not able to figure out how to do it. I found the example projects which have the FreeRTOS component so I guess it must be possible to do in some way.

I'm having difficulty setting up an SPC560P50L project for CAN. The given example (OS-less CAN) seems to due internal loopback which is not very useful for my application. (pinouts arent even automatically set)I'm using the discovery boardhttps://www.digikey.com/product-detail/en/stmicroelectronics/SPC560P-DISP/497-14706-ND/4866312I need to transmit and receive data at 250Kbps. I was able get transmission working by changing Time quanta (TQ) bits and read it on a PC application and by enabling the PB0 pin. I'm having difficulty receiving data on the RX line. My breakpoints do not trigger for "RX==OK". I've tried variations of disabling bits in the MCR like LPB and SRX_DIS (the bits I believe are responsible for the "virtual/internal" bus they use in the example.) but have had no luck.Are there any sample projects that transmit out out the board to an external node and receive from an external node? Let me know if there is more information I can provide

Hi,I am reading a burst of data 3072 half words from slave SPI device.The Slave device requires NSS to be released after each half word transmission.When I loop on HAL_SPI_TransmitReceive() function with size =1 for 3072 times it's OK.but when I try to do it in one shoot using Size() with size = 3072 , the NSS is set low for the whole 3072.the same happens when I try to use DMA "SPI NSS is low during the whole time of the 3072 half words". I set NSSPMode = SPI_NSS_PULSE_ENABLE;Here's my SPI Initialization tag.hspi4.Instance = SPI4; hspi4.Init.Mode = SPI_MODE_MASTER; hspi4.Init.Direction = SPI_DIRECTION_2LINES; hspi4.Init.DataSize = SPI_DATASIZE_16BIT; hspi4.Init.CLKPolarity = SPI_POLARITY_LOW; hspi4.Init.CLKPhase = SPI_PHASE_1EDGE; hspi4.Init.NSS = SPI_NSS_HARD_OUTPUT; hspi4.Init.BaudRatePrescaler = SPI_BAUDRATEPRESCALER_8; hspi4.Init.FirstBit = SPI_FIRSTBIT_MSB; hspi4.Init.TIMode = SPI_TIMODE_DISABLE; hspi4.Init.CRCCalculation = SPI_CRCCALCULATION_DISABLE; hspi4.Init.CRCPol

With an STM32F764 I want to receive 33 bytes from 11 daisy-chained 24 bit ADCs via SPI in read-only mode. The received data looks okay but there are 37 to 39 bytes in the buffer. Also with other byte numbers I receive 2 to 6 bytes more than expected.HAL_SPI_Receive_DMA is called by a GPIO interrupt from an external ADC when the 33 bytes are ready. After finishing the DMA the buffer content is processed in Sampling(). There is no other communication taking place on SPI3.I have attached a scope screenshot which shows the excess data in red./*SPI init for external ADCs (only Rx)*/ uint8_t SPI3_Init_ADC(void) { hspi3.Instance = SPI3; hspi3.Init.Mode = SPI_MODE_MASTER; hspi3.Init.Direction = SPI_DIRECTION_2LINES_RXONLY; hspi3.Init.DataSize = SPI_DATASIZE_8BIT; hspi3.Init.CLKPolarity = SPI_POLARITY_LOW; hspi3.Init.CLKPhase = SPI_PHASE_1EDGE; hspi3.Init.NSS = SPI_NSS_SOFT; hspi3.Init.BaudRatePrescaler = SPI_BAUDRATEPRESCALER_4; /*SPI3_CLK = 12.5 MHz*/ hspi3.Init.FirstBit = SPI_FIRSTB

STM32F746/AtollicI want to receive periodically a certain number of bytes from an ADC via SPI using DMA.Since there is no Tx line, I thought it would be correct to set the SPI at SPI_DIRECTION_2LINES_RXONLY and to program a DMA for Rx. I called this DMA with HAL_SPI_Receive_DMA(&hspi3, SplRxBuff, 33) and expected to receive 33 bytes in SplRxBuff.My buffer actually receives the 33 bytes but the SPI generates additional clocks which I want to avoid.In this forum I got the advice to use SPI_DIRECTION_2LINES instead of SPI_DIRECTION_2LINES_RXONLY and to add a Tx DMA even if there is no GPIO for Tx.I tried to do this but I don't receive any data. What could be wrong?Here the DMAS for Rx and Tx are set:/*DMA 1 / channel 0 / stream 0 transfers data from external ADC to sample registers*/ __HAL_RCC_DMA1_CLK_ENABLE(); /*DMA clock*/ hdma_spi3_rx.Init.Channel = DMA_CHANNEL_0; hdma_spi3_rx.Init.Direction = DMA_PERIPH_TO_MEMORY; /*from SPI to memory*/ hdma_spi3_rx.Init.PeriphInc = DMA_PINC_

I created some simple project in CubeMX for testing timer6 functionality. I configured PSC (prescaler) and ARR (automatic reload) registers. For now the interrupt handler is running correctly (it is running at calculated period), however I needed to add some special code in the end of this handler:void TIM6_DAC_IRQHandler(void) { /* USER CODE BEGIN TIM6_DAC_IRQn 0 */ uint32_t z; static uint32_t y = 1;    y ^= 1; set_gpio(y);   htim6.Instance->SR = 0; z = htim6.Instance->SR; }to get it working properly.I mean - in the 10th line I'm trying to acknowledge the interrupt flag (clear it in SR status register ). It should work but it doesn't. I have to add the 11th line to get it work. As the proper work I mean that the blue led is blinking accordingly to the set period. Blinking led is done by set_gpio() procedure.The strange thing is that when there is no the 11th line the program doesn't work properly. I thought that zeroing the SR should acknowledge the inter

Hi,I came across of this video of people counter recently from STMicroelectronics. I was wondering where can I find more information about it or code. Because , I don't understand how field of view is divided into two zones. I couldn't find anything like that in the API.

Hello,I'm trying to use both channels of the DAC on STM32L432, but I'm having a very annoying issue: channel 2 only goes up to 0.5V! I think I've configured both channels correctly, because both channels output voltage that changes with my code... but the output just looks like this:What I expected to see was two identical triangle waves... I'm sweeping an integer from 0-4095 and back down to 0, and sending it to both DAC's. I've tried multiple different commands to write the values to the DAC's, including:HAL_DAC_SetValue(&hdac1, 1, DAC_ALIGN_12B_R, dac_val);HAL_DAC_SetValue(&hdac1, 2, DAC_ALIGN_12B_R, dac_val);and this:DAC1->DHR12R1 = dac_val;DAC1->DHR12R2 = dac_val;and this:HAL_DACEx_DualSetValue(&hdac1, DAC_ALIGN_12B_R, dac_val, dac_val);All produce the exact same wave forms in the photo... Am I doing something wrong? Do I need to configure the two channels differently?Here is my config:static void MX_DAC1_Init(void){ DAC_ChannelConfTypeDef sConfig = {0};&nbs

HiWhich registers can be read/write on the STUSB4500? What are the register addresses?The datasheet only mentions the NVM parameters and their default values, how do you set them via i2c?ThanksJM

I have a problem with a hardfault in my system that I cannot resolve. The problem occurred while operating the display. When I change the transparency value, hardfaults suddenly occur (BSP_LCD_SetTransparency). But elsewhere in the program.Now I have a hardfault function that should give me information about the cause. Unfortunately I don't know how to interpret the registers. This is the function in which the debugger jumps:void HardFault_HandlerC(unsigned long *hardfault_args){   volatile unsigned long stacked_r0 ; volatile unsigned long stacked_r1 ; volatile unsigned long stacked_r2 ; volatile unsigned long stacked_r3 ; volatile unsigned long stacked_r12 ; volatile unsigned long stacked_lr ; volatile unsigned long stacked_pc ; volatile unsigned long stacked_psr ; volatile unsigned long _CFSR ; volatile unsigned long _HFSR ; volatile unsigned long _DFSR ; volatile unsigned long _AFSR ; volatile unsigned long _BFAR ; volatile unsigned long _MMAR ;   stacked_r0

Hi Dear'sI'm currently using the mb96f683 series microcontroller.I want to choose an alternative to the scp family for this microcontroller.Please help me if anyone has any information.

Hello,I tried a project created by @Mon2​ in this post. I've converted the SW4STM32 project to Atollic one and build it with arm-atollic-eabi-gcc and arm-atollic-eabi-g++ (gcc -v 6.3.1). Everything worked fine so i swapped the resolution in *.touchgfx file to make it landscape, edited the screen and generated code. Then i added the line HAL::getInstance()->setDisplayOrientation(ORIENTATION_LANDSCAPE);to main.cpp (just before start of kernel) and suitable include. Rebuild the project and uploaded it to the board. After these steps the UI components like buttons (except flex button), sliders and some others does not render correctly (pic bellow), but function normaly.So my question is - What am i doing wrong? Or is this some bug in TouchGFX? (found similar issue here but for STemWin) Edit:added zip with project

The ST202EB (ST202EC, ST232EB, ST202EB, ...) RS232 receiver's datasheets shows the following application circuit.Table 7 lists recommended capacitors values for C2-C5 (for the device ST202E is states 0.1 nF, for device ST232 it states 1uF).I think this is a typo. It should rather read C1-C4, as these capacitors are associated directly with the voltage doubler and voltage inverter stages of the tranceiver IC. I believe that C5 is rather a simple bypass/decoupling capacitor.What do you think?Best regards,Dan
