Hiso I am trying to get the UART2 on my STM32G031K8Tx up and running. RefManual shows in Chapter 5.4.21 a CCIPR register (Peripherals independent clock configuration register), where bits 2-3 relate to the USART2.When looking at the device specific h...

Hello,I am trying to trigger each DMA read of my SPI to happen on update event Trigger output of my Timer but I don't think I have it setup correctly.I've seen this done using the internal ADC, where you can set the external conversion trigger source...
RM0444 Rev 5 Page 377 says • TS_CAL2 is the temperature sensor calibration value acquired at TS_CAL2_TEMP(refer to the datasheet for TS_CAL2 value)• TS_CAL1 is the temperature sensor calibration value acquired at TS_CAL1_TEMP(refer to the datasheet f...
Hello,I notice in the STM32G030x6/x8 datasheet, Table 18 that the max input voltage on FT_xx and any other pin are VDD + 4V and 4V respectively. Does this mean those pins can be safely driven with 3.3V when the MCU is unpowered?Thanks,Nicholas
As indicated by an4759, I am trying to use the 50Hz mains reference to improve the RTC accuracy of an STM32F413ZH.However, the results I get are much worse than without using the reference:LSE only: 0.6s/dayLSE+50Hz: 7.5s/day (test duration 4 days)Ac...
Hello,During a UART transfer I used the HAL_DMA_Abort_IT() function. The transfer stopped but the DMA handle stays locked and in the HAL_DMA_STATE_ABORT. When in this state the only thing to do is reinitialize the peripheral.Anyone have some feed bac...
Hai, I am working with ST Nucleo H743ZI board for analog-to-digital conversion without CPU intervention between samples, by using DMA in Zephyr platform. Is there any ready-made example for the above, that I can refer?Thank you. Sachin
Hello ,in STM32 H742 data sheet I find CAN pind with or without the suffix FD_MODE, but there is no explanation on it. What does that mean? CAN peripheral has only one output for Rx and Tx each. Can't I use those without FD_MODE when using CANFD but ...
I wanted to use RTC Circuit for Supercap.I have designed circuit (Check Attached snapshot).but i dont get back up time? can anyone explain do we need to do any provision in controller.It seems that capacitor is discharging very fast
