What is accurate way of generete microsecond delay function without systick timer ?
Here is my code, but its not working correctly void DelayMicros(uint32_t micros) { uint32_t multiplier; multiplier = SystemCoreClock / 4000000; micros = micros * multiplier - 10; /* 4 cycles for one loop */ while (micros--)...
Hi, I've purchased an STM32H723ZG Nucleo Board to evaluate and test the potential of the onboard DAC. The max sampling time for the STM32H72x with the max bus speed at 137.5MHz is 51.1Msps as described in the AN4566 but I can't reach them.
I'm trying to generate a 1.2 MHz sine burst using the DAC, DMA and Timers. Everything works fine but only up to 200-250KHz then increasing the frequency the amplitude begins to decrease.Moreover I've managed to reach about 25Msps and it seems impossi...
Resolved! STM32H747IGT6 Flash read leading to hardfault
Hi,We have written the data in Flash Bank 2 sector 7 successfully. Power cycled the board and trying to read the stored data from Flash Bank 2 sector 7 and found Hadrdfault error at 64th byte.-> The data stored in the form of char.-> Using HAL librar...
How to receive data by using SPI communication ?
I use the STM32Lo538 disco board, and this board is connected to one sensor. Moreover, the protocol of this sensor is SPI. I faced difficulties receiving the data from the sensor. When I watched the waveform of this sensor, I noticed that the CS pin ...
Timer Encoder
Hi, I am using STM32F105 MCU.I have made a mistake in Hardware and switched two pins around. I have two signals from a encoder which they are connected to MCU in wrong way. SignalA ---> PC9 (TIM3-CH4)SignalB ---> PA8 (TIM1-CH1)I want to use a combin...
Resolved! HAL_PWREx_EnterSHUTDOWNMode not working due USART_DMAREQUESTS_SW_WA being set on stm32u5xx
On stm32u5xx HAL_PWREx_EnterSHUTDOWNMode will not work when a DMA is still active.The fun part is, that after a uart dma transmit, the DMA transmit enable flag is not cleared due the undocumented define USART_DMAREQUESTS_SW_WA.What's the reason behi...
Resolved! UART receiving issue at low clock speed
Hi All,Microcontroller running on 2Mhz clock speed, UART is configured at 115200 baud, Transmitting is working fine but facing issue while receiving data by interrupt, UART error occurred but not showing error number(huart.error =0, NO frame error, p...
Absolute max rating for ADC pins on STM32G071 device family
We are using STM32G071 device family in our projects and need information on absolute maximum ratings for voltage on ADC pins.Datasheet states different values for different pins.Can you please confirm what are the abs max values for ADC pins on STM...
