Can sdio f_mount affect UART port?
Hi!I have a problem with the simultaneous use of an SD card (with SDIO) and the uart port with GSM module connected. The SD card works flawlessly all the time. Communication with the GSM module is very unstable when I use the SD card - using the f_mo...
which mcu can configuate two UART ports and two SPI ports： 1，UART speed must higher than 115200bps； 2，All SPI ports work as Slave mode，speed must higher than 40Mbps；
那款MCU�?�以�?置两个UART�?�和两个SPI�?�：1，UART�?��?求速率115200bps；2，SPI�?�为Slave，速率�?求高于40Mbps；
STM32G031xx: Mistake/Bug in device specific header file???
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...
Hi. I boot with stm32L010C6Tx. I am in standby mode. While waiting in standby mode, it shows between 3.1 micro amps and 50 micro amps 50 microamps is too high, I can't use it like this. . I turned off all peripherals. What else should I turn off? Why coul

Trigger SPI Read using Timer Update Event
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...
Resolved! Where is the calibration data for the Temperature sensor in the STM32G031?
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...
Max voltage on pins when unpowered?
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
Resolved! RTC Reference Clock (50Hz) worsens the LSE accuracy
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...
Incomplete HAL_DMA_Abort_IT() in STM32F7xx_HAL v1.16
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...
