Solved

We are using the CR95HF over SPI and communicating with a single NTAG213 tag.I can successfully configure the reader and read 4 pages of user memory reliably using the READ command: 00 04 03 30 04 28. // Reads 16 bytes from Addr 0x04We would like to read multiple blocks using the FAST_READ command but the following command structure gives an 0x87 error;00 04 04 3A 04 07 28Any idea why this doesn't work?

I have an STM32F401CDU6 blackpill board and I have a USB not recognize code 43 error when activate dfu mode. It's don't do it 3 months ago

I have the following code where the variable string takes on the float value toPC correctly. I step into the HAL_UART_Transmit_IT and step over all the assignments and all looks fine yet I never see the TDR register update with the first value. Furthermore my while loop just hangs. Should I be doing something else for the uart to send data??I am connected to the STLINK port on the board and have the UART configured for 19200, 8 bit, No parity and I see nothing come over the port. The TE, RE, UE and TXEIE bits in CR register are all set.Thank you for (uint8_t k = 0; k < NO_ADC_CH; k++) { static char string[7]; ISR.usart_txToPC = F; /* * LMT87 linear equation * T = V - 2.6355 / -13.5mV * equation represents 0C - 50C */ float toPC =(((float)(stream[k]) / 4095 * 3.3) - 2.6355) / (-0.0135);   sprintf(string, "%2.2f\r\n", toPC); HAL_UART_Transmit_IT(&huart1, (uint8_t*)string, strlen(string)); while(!ISR.usart_txToPC); }  vo

I'm a beginner in working with Embedded Systems. I'm confused over OpenSTM32 System Workbench and Cube IDE. Could you please clarify me on this.Thanks

I'm trying to send CAN messages with the STM32F103C8T6 microcontroller (blue pill hardware with genuine ST chip) to a CAN analyzer without success.I'm using STM32CubeIDE v1.12.0. I double checked the hardware, I'm using PB8 and PB9 pins to connect to the CAN transceiver (SN65HVD230 ) RX and TX pin respectively, I have 120 ohm resistor on both CAN line termination, I settled CAN baudrate to different baud but the result is always the same, no pin level changing on TX pin PB9, it remains always at 3.3V (looked with a scope meter), it seems that the CAN cell is not connected to the external pins. I'm not using the USB that is disabled, external 8 MHz crystal with PLL to have 72MHz clock. The code works because I have a LED that correctly toggle its status every 1 second, after a while the CANtransmit function HAL_CAN_AddTxMessage(..) return an error because it doesn't find a free trasmit mailbox. Attached the main function, please help

Hey!!I have a BLE application which runs on custom server profile. There are few characteristics of a given service, where the client can modify them. I want to read these characteristics once they are updated by the client. I have tried to use "aci_gatt_read_handle_value" API but I'm not sure whether my implementation is correct or not.My implementation: ZoneConfigurationStatus_t zoneStatus; aci_gatt_read_handle_value(CustomContext.CustomZone_Configuration_StatusHdle, 0, SizeZone_Configuration_Status, &SizeZone_Configuration_Status, &SizeZone_Configuration_Status, &zoneStatus); LOG_DEBUG("zoneStatus :%d", zoneStatus);Can anyone help me out with this?Thanks,Akash

touch controller //MX_I2C3_Init(); If you do, it will not come out of the interrupt void MemManage_Handler(void). I want to use it as GPIO without using touch controller.

We are using LPDDR2 and have wired the data bits as per the ST provided example STM32MP15XXAD_LPDDR2x16-Example-A01_Schematic.PDF (attached)We have swapped the same bits in the DQ15:8 byte as per the PDF but I can't find anything to tell me how to perform this swapping in the devicetree or otherwise.Below is the screenshot from the Application Note detailing that bit swapping is possible.

Hello,We observe issues with a set of stm32F407ZETx.The application stalls / hangs somewhere while calling MX_USB_DEVICE_Init(). We are using the USB in CDC class. The board is powered via a USB cable, and the issue is not observed when using a good-quality USB power block, but it is observed if we e.g. put a dongle in between (https://us.transcend-info.com/product/card-reader-accessory/hub2). The production site (in a different country) is also observing these issues, I'll ask if they use a hub as well.The application seems to hang, but I could not pinpoint where exactly, since the program counter register suddenly becomes 0x0!!! That seems to happen on a random place during MX_USB_DEVICE_Init(). Sometimes, the application recovers automatically (on the production site, they say that the startup time usually takes 2 minutes instead of 3 seconds), but on our reproduction setup, the application never recovers automatically.Surprisingly, the application DOES recover if we touch the groun

I've recently updated our application from 4.18 to 4.20, and I've noticed a couple of rendering errors with TextArea. They occur when setWideTextAction() is set to WIDE_TEXT_WORDWRAP, and the text area wraps.The first problem is related to multi-line text areas. When calculating the bounding box for rendering, it only considers with width of the first line. If the second line is longer than the first, it is truncated. This has already been reported (search for "touchgfx truncated line when using word wrapping"), but there's no resolution there. Regenerating the project does not help me.I've done some investigation, and the issue appears to be in TextArea::calculateBoundingBox. It correctly calculates the height of the bounding box, but the width is set to the first line of text only. If the second line is longer, it gets truncated when rendering.I've looked at the code in TextArea.cpp; specifically, this section (lines 266-277):do { wtis.getStringLengthForLine(lineHeight * 2 > widg

Dear Sir,In datasheet, it says that Angular rate zero-rate level is +/- 1dps,does it means that when the chip soldered on PCB and in flat stationary state, the expected value is +/- 1dps or close to +/- 15 counts for +/-2000dps scale?What is the min and max G_TyOff? Not found in datasheet.Thanks.

Hello all,I am working on dual core stm32wl55.If the start address of CM4 is 0x08000000 and the start address of CM0 is 0x08020000, then everything works well, both applications work fine.But if i change the address location of the CM0 from 0x08020000 to 0x08027800, the the CM0 doesn't work, only CM4.The STM32WL55JCIX_FLASH.ld of CM0:system_stm32wlxx.cDoes anyone have an idea what is wrong?

Hi, I'm setting up a custom board with STM32G431CBT6 to control a 6-step bldc motor. I want to use comparators to protect against overcurrent.My problem I configured the bkin input and comparators. the bkin input works, the comparator also works separately (puts out an external signal). But the PWM does not stop when the comparator is working. I can see the active output of the comparator, but it has no effect on the pwm.I created a simple program to test this, no motor control, just complementary PWM.I want it to work at the hardware level. Can someone tell me what I'm doing wrong?I add screenshots and code.MX_GPIO_Init(); MX_TIM1_Init(); MX_COMP1_Init(); MX_DAC1_Init(); /* USER CODE BEGIN 2 */   HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_1); HAL_TIMEx_PWMN_Start( &htim1, TIM_CHANNEL_1 );   HAL_COMP_Start(&hcomp1);   HAL_DAC_SetValue(&hdac1, DAC_CHANNEL_2, DAC_ALIGN_12B_R, 4000); HAL_DAC_Start(&hdac1, DAC1_CHANNEL_2);   HAL_DAC_SetValue(&am

Good evening stm32 dwellings, i have a flash problem.I find myself with the need to write a config file independent to my programm code.In order to do that my programm uses pointers to specific memory pages of my stm32f105:define ADDR_FLASH_PAGE_54 ((uint32_t)0x0801B000) /* Base @ of Page 54, 2 Kbytes */ #define ADDR_FLASH_PAGE_55 ((uint32_t)0x0801B800) /* Base @ of Page 55, 2 Kbytes */For debugging purposes i created a temporal setup function that writes the a hardcoded config structure directly to my flash. (<- this is working fine, reading and writting)BUTOnce i build my own configFile.bin and try to flash it with stm32cubeMX i get this:  the flashed data looks fine when i read the memory, but the mcu is locked, once i start a debugging session it goes into hardfault at random moments.this is the verbosity output of the stm32cubeMX flashingI have no idea of what is going on....16:38:55:746 : Memory Programming ... 16:38:55:756 : Opening and parsing file: archivobinario

There are one of these for every relay on board​. Thanks for the help.

Hello everybody! Just wanted to clarify. I have still been playing with the TIM1 module. The datasheet for STM32U575ZI states that pin's PB13 alternate function TIM1_CH1N - is the first in the list, thus its number is zero. Yet, the TIM1_CH1N signal goes out only when I write "1" into the corresponding field in GPIOB AFRH register, which means that in reality TIM1_CH1N signal is actually the alternate function no.1, not zero. Does it meant that the datasheet is incorrect, or I simply misunderstand something? Thank you guys!

Hello,I am having difficulties with the MMC bus and the external SDIO wifi module. We are using the wifi module jody-w263 from U-blox with the OSD32MP1, and the communication with the module works, but it is quite slow. The wifi module is capable of SDR 104 and DDR50 communication speeds, but I add the support to the DTS, the communication is broken and the device returns the -110 while initializing.How can I add support for higher speeds?I attach the working dts, dmesg, ios and caps, and relevant schematic.Any suggestion will be appreciated.Best regards,Tomáš.

JWPS. Also, what exactly is this bit?

I'm trying to find an embedded solution to replace an SD Card.Basic non-volatile memory, I2C or SPI read/writes.I spotted ST NVRAM, but can't seem to find much about it - is this a new or discontinued product?Are there any other options that I should be considering?Thanks,Ben
