Im using a STM32F030C8T6 with PWM output to generate a sound output. I would like to use the repetition mode of the TIM1 so it will output the same PWM period 6 times.If I configure the timer and use both HAL_TIM_Base_Start_IT() and HAL_TIM_PeriodElapsedCallback(), I do get a interrupt after 6 repeats. ...... But the PWM output is not switching.Alternatively I can configure the system for HAL_TIM_PWM_Start() and HAL_TIM_PWM_PulseFinishedCallback() and the PWM output generates a waveform BUT I get an interrupt every cycle (not every 6th). Everything I have seen online seems to suggest that it should easily be able to generate several pulses and then interrupt once done.My thoughts are that this might be related to the output pin of the PWM not being initialized properly, but I'm open to any thoughts.

 last time also this problem was occured so I installed it again after that it run for some days now again the problem has occured. When I open Touchgfx one msg comeSorry - something unexpected has happened which caused an error to occur in the Designer.For more information, see the log file located at: C:\Users\Kaushal\AppData\Roaming\TouchGFX-4.21.3\TouchGFXDesigner.logPlease someone help to give the solution of it.

Hello,I am currently trying to set up a minimal example of using DMA for ADC conversions on a NUCLEO-F303K8 development board. I'm using the CMSIS device headers rather than the HAL, so I apologize if my issue is due to misunderstanding something in the reference manual.I have been able to set up the timer and ADC to regularly trigger the ADC interrupt on end of conversion and read the data, but I have been unsuccessful in implementing the DMA equivalent -- triggering a DMA transfer on end of conversion directly to RAM. I have been receiving DMA full transfer interrupts as expected (on the timing interval + conversion time), but the ADC reading transferred by DMA is garbage.Here's my full program:#include <stdbool.h> #include <stdint.h>   #include "stm32f3xx.h" #include "core_cm4.h"   #define ADC ADC1   #define ADC_DMA_CH DMA1_Channel1 #define ADC_DMA_IRQ DMA1_Channel1_IRQn   #define ADC_GPIO_PORT GPIOA #define ADC_GPIO_PIN 0 #define GPIO_MODE_ANALOG 0b1

AN2606 in description of Pattern 11 entry combination appears to indicate, that there's one combination when BOOT_LOCK option bit is ignored:However, this contradicts the RM:Can ST please clarify.Thanks,JW

Hi,I try to connect ADC channels with libiio for my custom board based on the stm32mp157caa3. I followed the instructions from the linkhttps://wiki.st.com/stm32mpu/wiki/IIO_libiiohttps://wiki.st.com/stm32mpu/wiki/ADC_device_tree_configuration#DT_configuration_examplesbut without success.

I am currently implementing a UART communication on a STM32F1. As I understand from the manual, the ORE bit does block all further Rx until it is cleared but the other error flags (PE, NE, FE) do not block Rx when set.How is the behaviour of the UART error flags and the data register (DR) in the following 2 scenarios. (in both scenarios 2 bytes are received before checking the SR and DR).Scenario 1:** First byte contains an PE/NE/FE error** Second byte contains a correct byteIf I understood the manual correctly, all error flags (PE,NE,FE,ORE) are now set and DR contains the first (corrupt) byte. Is that correct?Scenario 2:** First byte contains a correct byte** Second byte contains a PE/NE/FE errorMy assumption is that the first byte is stored in DR but PE/NE/FE flags are set (because of the second, corrupt byte) and also the ORE. Is that correct?If both of my assumptions are correct, is it therefore true, that, if 2 bytes are received and all error flags are set, you cannot decide whe

Is there an OctoSPI sCommand configuration which will generate only 8 clock cycles and read the result from MISO via HAL_OSPI_Receive?I'm attempting to use Macronix code (MX25l2565G flash) tied to a single SPI bus channel via OctoSPI. That code uses GetByte() which performs a single byte read.I've tried several configurations, including setting InstructionMode and AddressMode to "None", adding/removing DummyCycles, but either I set an Instruction/Address mode and have an extra 8 clock cycles or HAL_OSPI_Receive fails. Thanks!Thanks!

I'm trying to attempt CAN on a STM32G473 MCU. While transmission seems to be fine, I'm not receiving any data back. The receive call back function is not triggering.Following is my setup:Below is the TxHeader and RxHeader initialization along with the call back function. I have a breakpoint in the call-back function which never gets triggered.FDCAN_TxHeaderTypeDef TxHeader; FDCAN_RxHeaderTypeDef RxHeader;   //uint32_t TxMailbox;   uint8_t TxData[12]; uint8_t RxData[12]; int indx = 0;   void HAL_FDCAN_RxFifo0Callback(FDCAN_HandleTypeDef *hfdcan, uint32_t RxFifo0ITs) { if((RxFifo0ITs & FDCAN_IT_RX_FIFO0_NEW_MESSAGE) != RESET) { /* Retreive Rx messages from RX FIFO0 */ HAL_GPIO_WritePin(GPIOB, GPIO_PIN_13, 1); if (HAL_FDCAN_GetRxMessage(hfdcan, FDCAN_RX_FIFO0, &RxHeader, RxData) != HAL_OK) { /* Reception Error */ Error_Handler(); } if (HAL_FDCAN_ActivateNotification(hfdcan, FDCAN_IT_RX_FIFO0_NEW_MESSAGE, 0) != HAL_OK) { /* Notification Error */ Error_H

by some mistake, we have a large batch of boards with LIS2DS12 sensor and STM32G030F6P6 mcu powered with 3.3 volts. but the maximum voltage for LIS2DS12 is 2.0 volts, and absolute minimum voltage for STM32G030F6P6 is 2.0 volts. so we tried to adjust on board power regulator down to 2.0 volt but we had boot problems with the mcu. so the question is 2.2 volt the absolute maximum of LIS2DS12 is safe for long term working condisitons ? because STM32G0 looks fine with 2.2 volts.also can we run LIS2DS12 with 2.5 volts (0.3 volts over the absolute maximum) i am asking this because we have a test batch and LIS2DS12 chips are working fine with 3.3 volts over weeks without single fault.

Hi,I am developing a device which uses CAN interface. My code is 'bare metal'. I am using arm-none-eabi combined with cmake and vscode. Assembly and CMSIS are taken from cube generated project.The problem is that immediatly after setting RCC_APB1ENR1_FDCANEN bit the FDCAN_IR_ARA bit is set by hardware. The code is very simple:void main(){  RCC->CCIPR &= ~RCC_CCIPR_FDCANSEL;  RCC->CCIPR |= RCC_CCIPR_FDCANSEL_1;  RCC->APB1ENR1 |= RCC_APB1ENR1_FDCANEN;  FDCAN1->CCCR |= FDCAN_CCCR_INIT;//here the FDCAN1->IR ARA bit is setted  while ((FDCAN1->CCCR & FDCAN_CCCR_INIT) != FDCAN_CCCR_INIT)    ;  FDCAN1->CCCR |= FDCAN_CCCR_CCE;  FDCAN1->CCCR |= FDCAN_CCCR_DAR;  FDCAN1->CCCR |= FDCAN_CCCR_PXHD; // Protocol exception handling  FDCAN1->NBTP = 0x100403;}I was not able to reproduce this error in STM32CubeIDE. I've pasted same lines to the empty project and it worked. Therefore i must by not doing something th

Hello guys, I am working with an STM32L071CBT6 MCU. I want to have a cycle of 10 minutes, where MCU works for 1 minute before entering to standby mode during 9 minute.Using RTC, I want to have an interrupt every 1 minute(60 s); but I don't want the interrupt to wakeup the MCU. I want to use a different RTC event to do so.Is it possible to implement? Please any suggestion on how to go with this would be appreciated

Can ST please provide a guide for bringing up a custom board without using the STPMIC? We are extremely space constrained and unable to fit the PMIC. For our use case we just want simple LDO's with bucks as required.There is no material I can find that outlines what the device tree should look like for TF-A, U-Boot and Kernel when STPMIC is omitted.

During testing to see what happens if power is interrupted during various parts of firmware update, I removed power from my test board while updating FUS. Now, when I connect via SWD using STM32CubeProgrammer, it shows the following: When I try to update FUS in this state (writing FUS v1.2.0 to 0x080EC000), I get an error, "FUS_STATE_ERR_UNKNOWN".Is it possible to recover from this state?

Hi,I'm using STM32F429 to talk to TI BQ40Z50 via I2C, and I ran into an issue I have no clue.First of all, the code simply reads registers, and it works on TI BQ20Z95. The same code doesn't work on BQ40Z50. The HAL library always returns HAL_BUSY, and the error code is 32 (timeout). However, the logic analyzer doesn't have any waveforms. Both SCL and SDA are held high the entire time. The most puzzling part is that if I disconnect the BQ40Z50, let the STM read registers (reads nothing obviously) several times, and connect the chip back. It works like a charm. any suggestions I can try?The I2C is running at 100KHz, with internal pull-up registers.Thanks!
