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
ia m using STM32h743II MCU and i am trying to transfer SPI data from spi4 block defined as SPI MASTER to spi5 block defined as SPI SALVE without success.I am using the HAL_SPI_Transmit from the SPI MASTER block (spi4 block) and HAL_SPI_Receive from t...
I am seeing a very strange glitch from the PWM output of TIM8:CH1 on an STM32F730.The timer is running on 216MHz internal clock, with an ARR reload of 617, giving a ~350kHz PWM output.There is also a no-output Compare on it's channel 2, used to trigg...
