I'm developing an app in Xamarin in order to read and write via mailbox the ST25 chip. In Android everything works fine but on iOS it's more complicated. Has anyone some example in Xamarin.iOS?Thankyou Davide.

How to open the STSW-IO-LINK evaluation firmware in the STM32CubeMX development platform? STSW-IO-Link is downloaded and extracted. The *.ioc file seems to be missing in the STSW-IO-LINK firmware package!

Hello,I am reading AN2606 and I am wondering if I am interpreting the document correctly. Is table 113 suggesting that the FDCAN bootloader is only available on pins PH13 & PH14 in the STM32H75 series? Since these pins do not exist on the 100 pin packages of the part, is it not possible to use the FDCAN bootloader on 100 pin packages?Thanks.

What can i do to fix the over current problem.i have a nucleo-F767ZI board and  it seems that by trying to power on a display there is a problem with the circuit at the backlight and now i get the LD5 for the over-current always on.At this stage i do not care about the display at all i need to be able to make the nucleo work normally by it self without an display.When i place power on stlink the over-current led is on and i can not connect to stlink with STMCubeProgrammer or with IDE.What can i do to fix the issue to work again normally?

    Recently, I got some projects from my professor and tried to solve that with my Nucleo-H755 Board. I found that the way How to debug this MCU, Stm32H755 is pretty different with other st mcu, so i followed this video to set the debugging environment.https://www.youtube.com/watch?v=jI1k6p-fduE After applying some settings, I checked that my board got a problem.I couldn't connect to my board anymore(Cubeide- Debugging Mode or Cube programmer connecting) but still can check the voltage of st-link and volume of memory Storage. I would really appreciate it if you could give me a suggestion to solve this problem.Thank you.           

Code generation with STM32CubeMx version 6.5.0 is missing the HAL_RTCEx_SetWakeUpTimer_IT () that should be in the MX_RTC_Init () function.

Question seems simple enough, but i cant find any information on this in the datasheet or refman:When i put the mcu in stop-mode using the hal driver, i call this function:HAL_PWR_EnterSTOPMode(PWR_MAINREGULATOR_ON, PWR_STOPENTRY_WFI);The first parameter of this function can be either PWR_MAINREGULATOR_ON or PWR_LOWPOWERREGULATOR_ON.The function seems to set the LPDS bit in PWR_CR register based on that parameter. According to the reference manual, this means:0: Voltage regulator on during Stop mode.1: Low-power Voltage regulator on during Stop mode.That is not enough information to decide what i should go with for my application."Low-power Voltage regulator" implies that the MCU consumes less power in this mode. How much less? And what is the down-side of using the Low-power Voltage regulator?

I think i correctly setted up the slave adress on 0x70 with the configuration window.Below my script on the Raspberry Pi. #include "main.h" #include "string.h" #include "stdio.h"       I2C_HandleTypeDef hi2c1;   UART_HandleTypeDef huart2;     void SystemClock_Config(void); static void MX_GPIO_Init(void); static void MX_USART2_UART_Init(void); static void MX_I2C1_Init(void);     int main(void) {     HAL_Init();   char msg[10]; int buf[12];   SystemClock_Config();     MX_GPIO_Init(); MX_USART2_UART_Init(); MX_I2C1_Init();   while (1) { if( HAL_I2C_Slave_Receive(&hi2c1, (uint8_t*)msg, 2, HAL_MAX_DELAY) != HAL_OK){ strcpy((char*)buf, "Error Rx\r\n"); }else{ strcpy((char*)buf, "OK Rx\r\n"); }       HAL_UART_Transmit(&huart2, (uint8_t*)buf, strlen((char*)buf), HAL_MAX_DELAY); HAL_Delay(500); }   }   /** * @brief System Clock Configuration * @retval No

            I made external flash loader for STM32H735G-DK. I’m able to read, write and erase flash. However, programming 1M of flash takes ~ 50 seconds. STM provided loader takes around 7 sec for the same. Octo SPI in both cases, clocks are the same- verified, DTR in both cases- verified. I am testing on the same board, the same STLINK, so hardware is not limiting factor.Would anyone have an idea what method STM loader uses for such a huge speed improvement?

Hey, I'm using a NUCLEO-G031K8 board. I currently have jink running on it, and I can easily run debug and program with the USB interface. I'm currently trying to flash it using an external jink EDU programmer, and I have also tried by buying a larger NUCLEO Board and snapping off the programmer to program it. All these seem to connect to the NUCLEO, but they all error when they try to erase the board. Do I have to connect Solder bridge 2 (st-link reset).Or is there another Configuration I have to do with the hardware?I have already soldered on the 5 programing pins, and also edited the NRST register so that it is not acting as a GPIO pin.any help would be gladly appreciated. 

I have already purchased P-NUCLEO-53L8A1 and VL53L8CH. How should I join them together and read out the histogram data. Can you provide a detailed guideline or experiment video for me? 

I am using my custom board PCB with STM32F103C8T6 MCU. I want to give a PWM signal to PB1 pin & want to set PB2 pin to HIGH. While giving the PWM to PB1, although I set PB2 pin status as HIGH, when I measure the voltage of PB2 pin it shows '0V' value. I am using keil uvision to developed the firmware. How do I solve this problem? Can I set PB2 to HIGH while giving a PWM to PB1? 

Hello,I need to implement delay macro, lasting just a few cycles.As the delay is so small I would not like to use TIMs o DWT.On Texas Instruments DSPs, I was used to implement this nanoseconds delays, using NOP() instructions.Unfortunately, as also written in STM32 Programming Manual this is not a good pattern on Cortex processors.On a previous post, related to another issue, I was suggested to use Data Memory Barrier (DMB), Data Synchronization Barrier (DSB), and Instruction Synchronization Barrier (ISB) instructions, instead of NOPs.How can I use this instructions, to implement a few cycles delay macro?Regards,Carlo

Hello,i need help how to edit linker file for placing array on specific address in external SDRAM connected via FMC.I'm working with 7" TFT 800x480 @ 24bpp via LTDC controller and i have configuration 2 layers and both double buffered. So in HW is connected external SDRAM 8MB four banks (2MBx4). I would like to use each bank for one buffer as recommended in AN4861 https://www.st.com/resource/en/application_note/an4861-lcdtft-display-controller-ltdc-on-stm32-mcus-stmicroelectronics.pdf.I added SDRAM and SDRAM section into linker script as follows:SDRAM (rwx) : ORIGIN = 0xC0000000, LENGTH = 8192K.......sdram (NOLOAD) :{. = ALIGN(4);*(.sdram .sdram.*)} > SDRAM But i don't know how to place four buffers into start address of each SDRAM bank.I tried to create 4 SDRAM sections instead of one:SDRAM0 (rwx) : ORIGIN = 0xC0000000, LENGTH = 2048KSDRAM1 (rwx) : ORIGIN = 0xC0200000, LENGTH = 2048KSDRAM2 (rwx) : ORIGIN = 0xC0400000, LENGTH = 2048KSDRAM3 (rwx) : ORIGIN = 0xC0600000, LENGTH =

Hi,I'm using STM32G070RBTx, and I use this formula from document RM0360 to compute temeperature:From page 56 of document https://www.st.com/resource/en/datasheet/stm32g070cb.pdf, I'm using:Avg_Slope = 2.5 and V30 = 0.76.The temperature converted value I obtain at ambient temperature appears reasonable ( 21 °C approx. )  but when the temperature increases the  raw value I get from ADC also increases but using formula above gives a decreasing temperature value and this is wrong.Please help.

According to AN5192 (last paragraph of page 50) if LIR is enabled (0x56:0x4F)  and SINGLE_DOUBLE_TAP is set (0x5B:0x80) "latched mode is applied to the double-tap interrupt signal only".But I only read single tap in TAP_SRC (0x1C:0x20) during ISR.As soon as I disable LIR I get both interrupts.Is there an error in AN5192 and only single tap will be signalled when LIR = 1?Or I made a mistake somewhere in the registers?Here is my register dump:# i2cdump -yf 1 0x6a 0 1 2 3 4 5 6 7 8 9 a b c d e f 0123456789abcdef 00: 00 00 3f 00 00 00 00 00 00 00 40 00 00 08 00 6c ..?.......@..?.l 10: 60 28 44 08 60 00 00 00 e2 20 02 0f 00 20 07 28 `(D?`...? ??. ?( 20: b3 01 0d 00 ee ff f5 ff b2 01 23 00 63 41 00 00 ???.?.?.??#.cA.. 30: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 40: cd 05 20 00 f3 05 20 00 00 04 00 00 00 00 00 00 ?? .?? ..?...... 50: 00 00 00 00 00 00 4f 06 86 06 8a 80 00 00 4a 00 ......O?????..J. 60: 00 00 00 fd aa 01 00 00 00 1a 21 21 40 06 00 00 ...???...?!!@

I was trying to fabricate a flexible NFC antenna for m24lr chip. Initially, I fabricated my design on a copper PCB. It worked perfectly fine with my NFC chip and facilitated NFC communication. I observed its S11 curve using a NanoVNA with a loop probe, and it showed the minimum of the curve within the expected frequency range (around 13.6 MHz).When I fabricated it on a flexible substrate (PET,) using silver nanoparticle ink, I found that the minimum of the S11 curve was lost. The antenna still worked fine with the NFC communication, but I got a flat curve everywhere, from 5 MHz to 50 MHz (I did not observe beyond that range.)I measured the resistance of the flexible antenna and found that it has nearly 600 ohms of internal resistance, whereas my PCB antenna had about 2 ohms of resistance. Then, I connected my PCB antenna in series with a variable resistor and observed the S11 curve while varying the resistance of the variable resistor. I noticed that as the resistance increased, the mi

Hello all.I have a question about how to use KMS_GenerateKeyPair() function. There are no examples in the code, and API description is not really enough for my little brain. Could somebody provide me an example on how it should be used? What kind of parameters, how to initialize them and so on. I would be grateful!

Hello,      I have a board based on the stepper driver L6472. I noticed that, when I do not provide input 12V for the motor (the motor 12V but I provide the 3.3V for the logic (VREG, VDD, SW), I find a voltage of about 2.6V on the VSA, VSB pins. I tried to exclude all other possible source on the board and I think that this voltage is produced by the L6472. To have a definitive confirm I should cut some PBC track. Before doing this I would ask if it is an expected behaviour (to have 2.6V at motor output).

I have initialized a project with STM32CubeIDE (the .ioc file) using the STM32F407G discovery.I want to produce on an output pin of the TIMER4 a PWM signal with a certain duty cycle, so I set in the .ioc file the various parameters and in particular the "Pulse" parameter which, if I am not wrong, takes values in the range [0 .. ARR]. The value 0 corresponds to 0% Duty Cycle while the value ARR corresponds to 100% Duty Cycle. Is this correct? Since I want to be able to change the pulse parameter dynamically without having to set it every time by opening the .ioc file ... I decided in the main.c to directly change the register responsible for the Pulse parameter. So in the Reference Manual I looked up what it was and I found "one pulse mode" (in the attached reference manual, see section 18.3.10). I have read it several times but I can't figure out which register stores the Pulse value of TIMER4.I found out "indirectly" that it's CCR3 register because, during the simulation/debug, i
