Solved

Hi guys,I'm playing with STM32WL (the Nucleo-STM32WL55JC1 to be precise). Also I'm using the SX1303 LoRa gateway (it's a RPi Hat from Waveshare).Node is next to the gateway.When it comes to send of the data, it takes quite long from passing the send command to receive the IRQ from radio:58s735:MW DEBUG: SEND REQUEST60s381:MW IRQ radio process...The ADR is enabled, but anyway I've tried to play with DF, setting it to 5 and turning the ADR but without success.I plan to use this stuff for light the bulbs and drive the blinders and the 1.5 second for the transmission is a way to long.Is there any way to speed things up? Has anybody the similar issue? What's even worse - if we are waiting a 1.5 second for the IRQ it may cause a lost of loot of energy in case of battery powered devices.

It doesn't install as the phrase pops up. "can't initialize plugins directory. please try again later​" I've tried everything. Please help me.window10 64bitintel core i7-6700 3.4GHz

Updating the program, even for a minor revision like moving from version 1.16.0 to version 1.16.1, the address of the firmware repository is reverted back to the standard.Due to hard disk space limitation I've changed it to a different location, how can I keep it in the preferences without the need to go and manually change it every time I update?It is a bit annoying, because last time, for example, I dowloaded twice the Firmware packages that I already had but in a different location.Thank you very much for the help. 

@hi_it all, I newly working in USB Host mode configuration in stm32h503rbt6 controller using Keil software(without Hall code),this isn't very easy for me, I can't understand, how to use this method.actually, this implementation is to communicate (stm32 (Host)) with Tablet(device).I spent one week to USB understand this concept but couldn't, so please can you suggest me and share some notes for achieve this configurationThanks,

Hello,I have STM32F767ZI and STM32F429ZI Nucleo board, which I want to configure in TCP Client mode. I have attached .ioc file and tcpclient.c and ethernetif.c files. This files I have downloaded from internet. Now here is my problem when I try to run this code my board is not getting connected to server. For server I am using Hercules software. My board/s are getting from ping response, but not getting connected to server.   void tcp_echoclient_connect(void) { ip_addr_t DestIPaddr; /* create new tcp pcb */ echoclient_pcb = tcp_new(); if (echoclient_pcb != NULL) { IP4_ADDR( &DestIPaddr, DEST_IP_ADDR0, DEST_IP_ADDR1, DEST_IP_ADDR2, DEST_IP_ADDR3 ); /* connect to destination address/port */ tcp_connect(echoclient_pcb,&DestIPaddr,DEST_PORT,tcp_echoclient_connected); } } /** * @brief Function called when TCP connection established * tpcb: pointer on the connection contol block * err: when connection correctly established err should be ERR_OK * @r

Hello! I am trying to enable SPI communication through the SPI3 interface on an STM32F103ZFH6. I am aware that pins PA15 and PB3 are used for JTAG and SWJ, but I have disabled both using:GPIO_PinRemapConfig(GPIO_Remap_SWJ_Disable, ENABLE); There is no clock signal on SPI3_SCK (PB3) and the pin is always low, as confirmed by using a logic analyzer. The SPI3_NSS pins work, after disabling JTAG though.I am certain that the SPI settings, clock, and initialization are correct because data is being sent on the MOSI line, and the NSS pin is manually pulled down correctly during communication, just the clock signal is missing. GPIO settings are also correct as the SCK pin is set to GPIO_Mode_AF_PP. I have also probed for continuity on the PCB and everything is correct. There is a series resistor on the MOSI, MISO, and SCK lines. I have added a screenshot of the logic analyzer output I get. Currently, I think the issue may be a hardware issue in the microcontroller itself, b

Hi, ST.I want to know if the stm32h7(h750vb) series supports sdio? The spec sheet only describes the SDMMC peripheral (memory card etc.), but I want to use SDIO in my project to connect with esp32 to use WIFI (using esp-hosted library). I want to know if there is a way to achieve it?Thanks!

I'm working on a board that has a string of 6 SPI quad FET chips whose outputs I'm trying to PWM in software. The string of FET drivers have a latch signal to transfer the shifted data to the outputs. Because the DMA uses the SPI peripheral's FIFO, I need to generate the latch signal after every 3 bytes DMA'd to the SPI peripheral. It would seem that I need to set the SPI peripheral's FIFO size to 3 bytes and setup a SPI interrupt every time the SPI FIFO has emptied *and* the SPI data register is empty (i.e., after every 3rd byte has been completely shifted out). I don't see a way to set the SPI FIFO size. Since the FIFO size is 32-bits, I could send 4 bytes at a time (with one dummy byte) with the TXEIE (Transmit FIFO ready to be loaded) interrupt bit set, and when that interrupt occurred, if a TX complete interrupt was available I could enable that then to allow me to know when the entire 4-byte sequence was transmitted so that I could synchronously generate the latch signal to the S

For application benchmarking, I would like to access the data memory of the STM32F466RE in a single cycle.What is the data load latency of the STM32F466RE from data SRAM at 84MHz?and, if it is not single cycle, can I reduce the core frequency to decrease the number of SRAM access cycles?Thank you.

I am unable to find documentation on the different registers for hardware. I see registers like `TIM2->CCR1` mentioned everywhere, but I can not seem to find docs for it.Does someone have an idea where I can find the documentation for registers and functions?

I'm trying to debug a Zephyr RTOS application on the STM32H573I Discovery board using the STM fork of openocd and the on-board STLink. I'm running the tools on a Mac M1 machine, and building and flashing the code works fine, using the Zephyr west based toolchain and VSCode.But when I start openocd with this config (copied from STMCube IDE): # This is an genericBoard board with a single STM32H573IIKxQ chip# Generated by STM32CubeIDE# Take care that such file, as generated, may be overridden without any early notice.

Hi,I have a custom board with STM32MP151 and have been trying to run it for quite some time. I have been fixing one mistake after another. But now I can't solve the last problem: [13:11:36:338] F/TC:0 0 probe_driver_node:436 Probing stm32-tamp on node tamp@5c00a000 [13:11:36:344] D/TC:0 0 probe_driver_node:449 element: stm32-tamp on node tamp@5c00a000 deferred 2 time(s) [13:11:36:354] F/TC:0 0 probe_driver_node:436 Probing stm32-cpu-opp on node cpu0-opp-table [13:11:36:357] D/TC:0 0 probe_driver_node:449 element: stm32-cpu-opp on node cpu0-opp-table deferred 3 time(s) [13:11:36:368] D/TC:0 0 process_probe_list:590 Unresolved dependencies after 3 rounds, 3 deferred [13:11:36:377] D/TC:0 0 probe_dt_drivers_early:774 Deferred drivers probing [13:11:36:377] D/TC:0 0 print_probe_list:397 Probe list: 2 elements [13:11:36:388] D/TC:0 0 print_probe_list:399 |- Driver stm32-tamp probes on node tamp@5c00a000 [13:11:36:392] D/TC:0 0 print_probe_list:399 |- Driver stm32-cpu-opp probes on

Hi! I'm working in an application where I want to start a series of ADC conversions every 10 seconds, take a hundred samples and stop the conversions. The way I thought of it is to use a timer (timer 1 in my case) to measure the 10 seconds and use another timer (timer 3) to trigger the ADC conversions. Once the 100 conversions are made, the timer 3 stops until the timer 1 counts to 10 seconds again.The problem that I have is that the timer 3 does the cycle only one time and after disabling the time base inside the ADC callback function I can't start it again from the TIM1 callback function. This works fine only if I don't use HAL_TIM_Base_Stop(&htim3).Am I doing something wrong or this method is not possible?    void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim){ HAL_GPIO_TogglePin(GPIOA, GPIO_PIN_9); HAL_TIM_Base_Start(&htim3); } void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef* hadc) { HAL_GPIO_WritePin(GPIOA, GPIO_PIN_8, 1); counter++;

I'm unsure whether this is a software issue or wake-up callback is by default not present for UART on STM32U535 microcontroller. The rest of callbacks seems to be in place.

Hello, i am trying to implement Eeprom Emulation on STM32H723 using the code that ST provided in STM32CubeH7-Master for STM32H743 series. In the EE_Init function, first thing that function does is this line of code:   PageStatus0 = (*(__IO uint16_t*)PAGE0_BASE_ADDRESS); #define PAGE0_BASE_ADDRESS ((uint32_t)(EEPROM_START_ADDRESS + 0x0000))  when i look at the value of PAGE0_BASE_ADDRESS, it corresponds to 6U+0x000. Is that normal? Doesnt this mean that we are reading from ITCM RAM?

Good day,we are currently integrating the XCUBE-Dpow library but are running into multiple issues due to the lack of code documentation of the library.- We are not using HTIM Channel-C but -D. After changing multiple entries in the template files of the library, the output works, but High/Low side are inverted.-> Is it possible to invert the dutycycle (High connected to TD2, Low to TD1) or invert the output configuration?We have tried but did not succeed.-> none of the protection functions are integrated, it is unclear if the K value is needed and also, in the documentation the REF value is not inserted into the ADC, as well Channel C is hardcoded.Also, in AN5496, it is missing that for the ramp to work the REF value in the Dpow library has to be set to:(uint16_t)(vLoop.m_Out) - is this correct?Is there any documentation I am missing? Many things are not intercompatible, and there also were some errors to fix after migrating to CubeFW 1.6.0It would also be nice to know which of t

I am working with the ST25DV tags.  I have generated a capability container, TLV Header and Terminator and construct a well-formed NDEF message with 5 records.  I am able to read/write single/multiple blocks and perform most actions that i need in interacting or editing the NDEF records themselves.I am now trying to split the user memory into different sections so that I can lock down RF write of the first 3 records and leave the last 2 records open for both RF read/write.I am currently testing on Android and attempting to open a configuration security session.  I am using the react-native-nfc-manager to help me handle some of the lower level aspects of working with these tags.Here is a simplified version of my function:async function openSecuritySessionAndroid() { if (promptRef.current) { await NfcManager.cancelTechnologyRequest(); await sleep(100); promptRef.current.show('Ready to Scan'); await NfcManager.requestTechnology([NfcTech.NfcV]); } try { const iso156
