Hello I ordered two NUCLEO boards, to start some projects on the ST32G03 platform. I was using the board with out an issue and connected to am Ubuntu 20.04 sys, updated the firmware on both and now one is working and the other is not, here is an outp...
HAL_StatusTypeDef HAL_I2C_Master_Transmit_DMA(I2C_HandleTypeDef *hi2c, uint16_t DevAddress, uint8_t *pData, uint16_t Size) { if(hi2c->State == HAL_I2C_STATE_READY) { if((pData == NULL) || (Size == 0)) { return HAL_ERROR; } ...
I'm got a Nucleo-F746ZG connected to a DC motor, which I'm driving via PWM using TIM1.I'm using TIM3 in quadrature encoder mode to read the encoder on the motor. The problem I'm encountering is the TIM3 CNT register is not incrementing fast enough. T...
I have spent the past week trying the demonstration projects and demonstration binaries for the B-L462E-CELL1 board. I have been able to compile and down load a number projects but none of them will connect to the Truphone website using the embedded ...
Hi all,I believe I am having a problem with the IWDG in my project. What's happening is that immediately after entering sleep mode the device wakes up again.From the research I have done, it looks like this is inevitable, and in order to deal with it...
Hey. I am trying to read multiple ADC channels using DMA but with no luck. My project settings:I have selected 4 channels and enabled Continuous conversion mode as well as DMA Continuous requests. I have also created a circular DMA for ADC : #include...
Hello,At work we have developed firmware on a stm32l0 based on different time base with systick and counters of elapsed time (10ms, 100ms and 1s). Therefore, some function are executed periodically.The board is powered with 3.3V.In order to measure c...
I am using below commponet MCU: STM32H7B3IIT6SDRAM: IS45S16800F-7CTLA1-TR FLASH: MX25LM51245GMI00I am revising the card design according to high speed signals. But how do I calculate the length of the paths to be drawn for SDRAM and FLASH?How many m...
Hi, I'm trying to read ADC data with 2us periods using ADC interrupts on Nucleo F334R8. I'm triggering ADC with TRGO event of Timer 2. I'm toggling a pin whenever callback function is called to debug using an oscilloscope. However, I cannot observe 2...
Hello ST community! We're using STM32F401RDT6.We use the RTC to maintain scheduled events that occur in the time we set, but not with the RTC's Alarm mechanism, rather our custom-made mechanism based on the current epoch time which is being updated e...
