The reference manual explains how I can select between adc_hclk and adc_ker_ck_input as the clock for the ADC but I can't find what the source is for adc_hclk. It is one of the AHB or APB peripheral clocks but which one? Nowhere in the manual can I f...
Hello,In stm32h7 I see in the "System architecture" diagram that SRAM3,SRAM2,SRAM1 are not passing through the cache.Yet, it seems that when using SRAM3 with DMA I must configure it as non-cacheable, otherwise I get junk in data.Can anyone please exp...
I am using STM32F446RE Nucleo Board and want to read internal RTC timing. But I am unable to get the time getting 00:00:00Here I shared my coreClock Setting: LSE : 32768HzSystem Clock: HSI : 84MHzint main(void) { /* USER CODE BEGIN 1 */ /* USER...
I'm trying to get this example to work with my custom hardware. The TX works fine. I can't get the RX to work.* This example was developed for the NUCLEO-F411RE board and my processor is an STM32F439ZIT6, not F411. Could this be the problem?* I ha...
I am looking for an MCU for a new project. Desired features:Ethernet, EEPROM, I2C, UART, SPI, PWM, 1MB flash, USB, ETM, possibly TQFP package, no BGA, operating voltage 3 - 3.6 V, OR 5V, -40C to 85 C operating range. Thanks,Priya
Hi, I am trying to find a MCU that both have an MMU and an internal scratchpad?My idea is usually Cortex-M series (low-end ones) do not have an MMU and an internal SRAM that can be used as a scratchpad / Cortex-A series (high-end ones) have an MMU bu...
Is it possible to externally trigger the ADC in group conversion mode + DMA continually? Nothing I have tried seems to work. It appears that I have to call a software conversion for each synced conversion? ``` LL_ADC_REG_SetTriggerSource(ADC1, LL_A...
Hi,Kindly share the MTBF or FIT rate of STM32F103RDT6.Warm regards,Monisha OM
I try to measure the VDDA on an STM32F302R8 MCU using internal voltage reference (VREFINT) and it works fine and gives the correct results as long as the VDDA is above 3 V. Below 3V the value of the AD conversion of the VREFINT rapidly increase and a...
Hello,I'm reading data from an external device using SPI in Receive Only Master mode. For this, I'm using the HAL function HAL_SPI_Receive_IT(), which as its name suggests doesn't use DMA, but is non-blocking and calls HAL_SPI_RxCpltCallback() when i...
