How can i Import the iOS NFC Tap SDKs to my swift app ? which Libs are relevant ?

Hello,I am trying to communicate with the bootloader by serial.Most of the times it works nice but sometimes it fails as I fail to enter the bootloader.To give a context, in order to enter the bootloader I set the rts of my FTDI high (this will set the bootloader to listen) and I send the 0x7F for it to get my baudrate and enter the bootloader. Then after the ack (0x79) if I send again 0x7F I should get a response (0x1F), at least some seconds after. This works most of the times, but sometimes it just doesn't.Any tip on what might be the cause? The image attached is a record of the data transmitted by serial. Another issue that also occurs sometimes is, after I do that, the stm32 just gets itself out of the bootloader into the app and starts sending the regular app serial messages.Thank you for your time and input.

1) I've checked multiple schematics for blue pill, black pill, etc., and saw capacitor and resistor on reset button line. I've built a test (pinout) board and without any capacitor or resistor. I can reset it (NRST pin to ground). May this cause a hardware or software fault in the future ? I've checked datasheet and there is only shows 0.1 uF capacitor for just protection. Do I need any other component on NRST line ?2) I'm using FTDI (also tried CH340G) for UART (via Demonstrator GUI) and unable to connect to board. Connections are correct: RX->TX, TX-RX, GND->GND, VDD->3V3. Tried all possible UART2, 3, 4 and so... Is this board can be able to program over UART or do I have a mistake ?3) On Bluepill there are Boot0 and Boot1 but 32G070 just have Boot0. I've already figured out I can program with STLink swdio, sclk etc but do I need any resistor like bluepill on Boot0 ? Tried to put a serial resistor like that but in that case I couldn't use STLink.Regards

I developed a stm32 project for the Nucle-H745ZIQ board with stm32cube ide, there's no issue downloading the code from IDE using its debugger. However, when I tried to download with stm32cube programmer, the code doesn't run (no expected actions can be observed on the board) after the download even though the cube programmer shows "download/verify successfully" and the "Device memory" tab shows data have been written to memory address. It doesn't happen every time, but it happens.The ide version is 1.6.1, programmer version is 2.8. The connection is "ST-LINK", Port is "SWD", Mode I tried "Hot plug" and "Under reset". And I tried both .hex and .bin generated from IDE, the problem could not get fixed.A brand new board is more likely to have this issue, no .hex file can run on board as expected by downloading from cube programmer. A workaround is to program the new board with CUBE IDE once, then it's less like to have this issue for this particular board while programming with CUBE progra

Hello, I use USART1 routed to PA9/PA10 (AF1 as per data sheet), so executing the line SYSCFG->CFGR1 |= (SYSCFG_REMAP_PA11 | SYSCFG_REMAP_PA12);should present the GPIOs PA9 and PA10 to pins 16 and 17 of the TSSOP20 package. Right?Well, pins 16 and 17 continue to carry PA11/PA12 no matter what the state of the two REMAP bits. I suppose these control a MUX each (as opposed to multiple bonding like e.g.PB3/4/5/6)?Is there anything I am missing? Thank you!

Seminar-NFC charging: the tiniest solution for wireless chargingQuestion: what international/European standards should I follow with regard to EMC/RFI when designing for NFC charging

It finally happened, i need two pins without pwm functionality to output pwm signals (minimum 1kHz)Im using an STM32f072R8Tx clocked with HSI48Mhz, my TIM1 is available.My idea is:TIM1 channels 1 and 2 set up as PWM NO OUTPUT with interruption enabled, discriminate the source of the interruption (channel).Toggle the corresponding GPIOs inside the IRQ function.Is there another magical way that doesnt interrupt my programm every milisecond?

I was wondering if one could define their own task tags (special comments like the default "FIXME" or "TODO") in the IDE? The IDE is Eclipse-based, but the preferences' window is not identical. So, the guides for Eclipse, like this one (https://stackoverflow.com/questions/9586478/ide-comment-keywords) do not work.

Hello,I've changed the impedance matching network on the NFC06A1 such that the system is resonant at 13.56MHz with an impedance of 2.6 ohms. The reader is in 5V mode with the regulator display register measuring 4.3V at VDD_RF. I have set the output resistance to 3.4 ohms.I expect that it would output 1.6 Arms (4.3 V / 2.6 ohm) or possibly 0.72 Arms (4.3 V / (2.6+3.4) ohms) with the VDD_RF regulator limiting the current to 350Arms. However, the i_lim flag remains zero.Is there a trouble shooting procedure I should follow for determining why the device will not output more than 350Arms?Thank you!Best,Oliver

Hi,I am trying to connect to a 16 bit parallel display interface. To write new data, I have to use pins on five different ports (GPIOs A, B, C, D, E). Right now I am setting these pins like this:PORT_D15->BSRR = (PIN_D15 << 16) | (((data >> 15) & 0x01) * PIN_D15) ;repeat for all other 15 pins.This is causing the display to update slowly, you can see the screen 'rolling in' from the top.On a previous controller all pins were in one port, and one access to PORT_DISPLAY->ODRwas enough to set all pins.Is there a quicker way to set all those port pins?

HI all,I’d like to create a system communication using LoRa protocol between 2 devices, I don’t want to use TTN. I’m newbie with LoRa I’ve seen Seed provide SDK to use LoRaWAN but I don’t want to use gateway or server. To be simple I have one device with LoRa-E5 and another device with another LoRa-E5, I’d like to be able to comunicate with LoRa between those devices, so it is End device to End device I think, is it possible ?

I am makeing a gauge background out of many circle widgets. I dont want to use static immage background because the position of segments can change depending on the maximum rpm. I have create this in TouchGFX designer and for each circle widget Designer created also a painter. Therefor there are many painter that have the same color configuration. Is it possible to eliminate some widgets and/or painters to reduce the memory consumption. part of generated code CustomGaugeBackgroundBase.cpp segmentBig1.setPosition(0, 0, 494, 426); segmentBig1.setCenter(247, 246); segmentBig1.setRadius(235); segmentBig1.setLineWidth(22); segmentBig1.setArc(-136, -133); segmentBig1.setCapPrecision(180); segmentBig1Painter.setColor(touchgfx::Color::getColorFrom24BitRGB(255, 255, 255)); segmentBig1.setPainter(segmentBig1Painter);   segmentBig8.setPosition(0, 0, 494, 426); segmentBig8.setCenter(247, 246); segmentBig8.setRadius(235); segmentBig8.setLineWidth(22); segmentBig8.setArc(134, 1

Hello,I am working on SAI part of the NUCLEO-F756ZG board and I observe an issue with the DMA.The configuration is:SAI A as a master with master **** out and audio mode = master receive. SAI B as asynchronous slave and audio mode = slave transmit. (SAI B is used to simulate a futur hardware codec)Both SAI use DMA, circular for SAI A and normal for B.On the board each pin (i.e. SCK, FS, SD) of both block are connected.The code is very simple: two buffers, the transmit buffer is filled with a sequence of numbers (0, 1, 2,...), HAL_SAI_Transmit_DMA and HAL_SAI_Receive_DMA are called. When HAL_SAI_RxHalfCpltCallback is reached the receive buffer is displayed. #define SAI_DMA_BUFFER_SIZE (320 * 8 * 2) static uint16_t __attribute__((section(".sai_dma_buffer_section"))) __attribute__((aligned(32))) sai_receive_buffer[SAI_DMA_BUFFER_SIZE] = {0}; static uint16_t __attribute__((section(".sai_dma_buffer_section"))) __attribute__((aligned(32))) sai_transmit_buffer[320 * 8] = {0};   stati

Hi,I have a project in stm32cubeide that I have been using and updating for a while and have not had any issues. Now however, I get 10:35:50 Build Failed. 6348 errors, 48 warnings. (took 6s.171ms)Looking at some of the errors, it ranges from undeclared variables, to not recognising number formats. It looks like a driver or path issue but the paths look OK to me. Cleaning the the project and rebuilding does nothing. Here is a screenshot of some of the errors and the path:  Any suggestions as to what I could try next would be appreciated.

After detecting a rise edge in interrupt line, I would like to keep a LED on until it detects a falling edge. Do anyone have idea of how to do it?

The application note AN2834 states that this parameter should be listed in the device datasheet. This is true for MCU families like F4, but not for G4. I know that there is a difference between slow and fast channels, but where could I find precise values?

We are using STM32H745I-DISCO which has a 16 MByte SDRAM.
