Solved

In the last 2 days I can't get any results using search engine on the website. For instance, when I type in any STM32H743II code there is only a message like in the picture below. The same situation is for any acronyms or Doc Ids. Is it only a problem on my system (Win 8.1) or browser (FF 84) or is it related to the server?

I'd like to use the STM32L4R9ZG microcontroller along with a HyperRAM memory such as the ISSI IS66WVH8M8BLL. I was reading through the ST application note AN5050 "Octo-SPI interface on STM32 microcontrollers" to familiarize myself with the process. On page six of the app note there is a table called "Table 2. OCTOSPI main features". There is a note associated with this table saying PSRAM is not supported with STM32L4Rxxx. What does this mean? PSRAM is clearly supported with these devices because the STM32L4R9I-EVAL board even has a PSRAM on it. Can someone please explain this to me?Thanks!Rob

HI All,I plan to use STM32L4S7ZITx cpu. I need to work with LCD screen which has parallel interface and connected to FMC. It works fine on demo board but i would like to offload the CPU. But i am not sure if FMC can work with DMA.I checked the following:The RM0432 (i guess it is the right reference manual for this cpu).On page 397 there is a table Tab54 which lists all multiplexer inputs to resources. There is no FMC listed there. So i guess FMC is not supported by DMA.An so it is not possible to offload the CPU from writing long memory chunks to LCD screen or to any memory connected to it.Am I correct?

Hi, this subject has already been treated with other boards in other forums, but libraries and tools have changed since then so i thougth i could open a new question. So i use CAN1 bus in the Discovery STM32F407 in order to share data between 2 discovery. I use a classic transceiver SN65HVD234 from Texas Instruments. I configured the Discovery with CubeMX and used CubeIDE. I'm using the HAL Library.I use the User button to fire an EXTI interuption that call HAL_CAN_AddTxMessage() an writes on the bus. Transmitting data works but not Receiving.The Hardware is working very well as you can see [in the picture][1]. However the end of the frame bothers me a bit, i don't know if this is nominal.Here's what I found using the debugger : The interruption enabled for FIFO0 never fires and the function HAL_CAN_RxFifo0MsgPendingCallback() is never called. So I think the problem comes frome the Filter and its registers that i don't really understand.here is the configuration code : I

__HAL_RCC_GPIOA_CLK_ENABLE(); GPIO_InitTypeDef agpio; agpio.Mode = GPIO_MODE_ANALOG; agpio.Pull = GPIO_NOPULL; agpio.Pin = GPIO_PIN_5; HAL_GPIO_Init(GPIOA, &agpio); __HAL_RCC_ADC_CLK_ENABLE(); RCC_PeriphCLKInitTypeDef adc_clk; adc_clk.PeriphClockSelection = RCC_PERIPHCLK_ADC; adc_clk.AdcClockSelection = RCC_ADCCLKSOURCE_SYSCLK; HAL_RCCEx_PeriphCLKConfig(&adc_clk); ADC_HandleTypeDef adc; adc.Init.ClockPrescaler    = ADC_CLOCK_SYNC_PCLK_DIV4; adc.Init.Resolution      = ADC_RESOLUTION_12B; adc.Init.DataAlign       = ADC_DATAALIGN_RIGHT; adc.Init.ScanConvMode     = ADC_SCAN_DISABLE; adc.Init.EOCSelection     = ADC_EOC_SINGLE_CONV; adc.Init.LowPowerAutoWait   = DISABLE; adc.Init.LowPowerAutoPowerOff = DISABLE; adc.Init.ContinuousConvMode  = ENABLE; adc.Init.NbrOfConversion    = 1; adc.Init.Discontinuo

I am willing to data transfer stm32746 to pc via usart and control pins.When I click the button stm doesnt send data via usart or stm doesnt control pins.Screen1View.cpp codes:#include <gui/screen1_screen/Screen1View.hpp> #include "stm32f7xx_hal.h" extern UART_HandleTypeDef huart2;   Screen1View::Screen1View() {   }   void Screen1View::setupScreen() { Screen1ViewBase::setupScreen(); }   void Screen1View::tearDownScreen() { Screen1ViewBase::tearDownScreen(); }   void Screen1View::led_on() {   /* HAL_GPIO_WritePin(GPIOA, GPIO_PIN_1, GPIO_PIN_SET); HAL_GPIO_WritePin(GPIOA, GPIO_PIN_1|GPIO_PIN_4|GPIO_PIN_2|GPIO_PIN_5 |GPIO_PIN_3, GPIO_PIN_SET); */ //HAL_GPIO_TogglePin(GPIOD, GPIO_PIN_5); //HAL_GPIO_TogglePin(GPIOD, GPIO_PIN_6); // textArea1.setVisible(true); char com_cevap[12] ="adc_veri\r\n "; HAL_UART_Transmit(&huart2, (uint8_t *) &com_cevap, 12, 200); btndurum.setAlp

I want to use the STM32H750. I want to configure the I2S2 to use the port PI0..PI1, but the CubeMX tool will not alloud me to do it. According the data-sheet it should be posible.Br. Poul-Erik.

Hello,Im trying to read data from a M24LR64E-R tag with password.So, Im using customCommand() function with these data :flag : 0x0acommand : 0xB3payload : bytes from password This command works on Android but on ios I receive this error :[CoreNFC] 00000002 83601300 -[NFCTagReaderSession transceive:tagUpdate:error:]:710 Error Domain=NFCError Code=100 "Tag connection lost" UserInfo={NSLocalizedDescription=Tag connection lost}It's the same with readSingleBlock command but I received the same error.Do you have an idea ?

Hello!I have a typography, which contains this set of symbols "0-9,A-z,�?-�?,0x20-0x7F,0x401,0x451"But I want to use China and Japan languages.In TouchGFXDesigner all OKBut in application - "????"How to fix?

Hi,I am receiving the wrong CRC16 value from the tag when it is answering error flags, for example:2020-12-16 14:01:18.143 writeMsg >> 02AA0200AA2020-12-16 14:01:18.148 writeMsg << 0F0F68EEI forced an error there (writing to the MB when it is off) and the tag correctly answered 0F0F, but the answered CRC (68EE) is not correct, according to the standard it should be 0x7478What am I doing wrong here? Is the tag really answering wrong CRCs for error codes or is there any other reason why this value is different?Thanks, Gustavo

Please, anyone has EZCV621 IC Datasheet?

I have a problem with using the printf function in Keil. I used the STM32CubeMX to setup a project and generated the code for Keil. All settings in CubeMX is standard, only thing changed is the USB_DEVICE set to Communication Device Class (Virtual Port Com).If this is setup and genrate for STM32CubeIDE and then in main.c I add #include "stdio.h" and within User Code 4 I insert the following, then printf is working on the USB connection./* USER CODE BEGIN 4 */int __io_putchar(int ch) { uint8_t c[1]; c[0] = ch & 0x00FF; HAL_UART_Transmit(&huart3, &*c, 1, 10); return ch;}int _write(int file, char *ptr, int len) { int DataIdx; for (DataIdx = 0; DataIdx < len; DataIdx++) { __io_putchar(*ptr++); } return len;}/* USER CODE END 4 */If i then do the same thing for keil, its not working, anyone who can guide me how to solve this.

I want to create my own machine.I'm trying to create with reference to following Wiki Page.https://wiki.st.com/stm32mpu/wiki/How_to_create_your_own_machine​In "2 Generate device tree" in the wiki page, I need to set device tree from STM32CubeMX to "mx" directory.However, OpenSTLinux Distribution Package (openstlinux-20-02-19) that I have install has no "mx" directory  in "meta-st-stm32mp-addons".​Do I need any other steps to create "mx" directory in "meta-st-stm32mp-addons" automatically?And, in the case that I want to change kernel or u-boot or tf-a device tree, all I need is to change device tree in "mx" directory?Do I need any other steps to reflect the change of device tree setting?For reference, I have tried to create "mx" directory manually and set device tree to "mx" directory, but bitbake failed.(Error message shows "No rule to make target arch/arm/boot/dts/xxxxxxxx.dtb")Best regards,H.

I'd like to run the dashboard on my iphone. I'm able to run it in Chrome on my mac with no problems, but am missing something about how to get this to work on my phone. Any help is appreciated!

Hi,I'm looking for an example schematic of a USB PD charger interface using STM32G071G8U. Current questions are:Is the available singe CC pad (PA8) all you need from the hardware point of view? Is there any option to connect D+ and D- to allow 5V loads to charge with higher power (DCP)?Our plan is to switch from a autonomous USB PD charge IC to the STM32G071.

Hello! I have textArea with wildcard, which is updated by Slider movingvoid OPTIONS_SCREENView::R_Slider_MOVED(int value) { RGB_LED_Sample_box.setColor(touchgfx::Color::getColorFrom24BitRGB(R_Slider.getValue(), G_Slider.getValue(), B_Slider.getValue())); RGB_LED_Sample_box.invalidate(); Unicode::snprintf(R_Value_textBuffer, 20, "%d", value); R_Value_text.setWildcard(R_Value_textBuffer); R_Value_text.resizeToCurrentText(); R_Value_text.invalidate(); }When I set values from 0 to 255, everything is fine. When reduce from 255 to 0 - problem: if the number is less than 100, then a 3 digit incorrect number, 1 and 2 - correct two-digit number, if less than 10 during the 2nd and 3rd digits of the wrong number, the first correct one digit number.values in variable "value" - are always correct.For example:255->255101->10189->89178->78111->1119->911What's wrong?
