HiMy name is Jonah and I’m working on STM32L031K4U6 .My device needs to go to standby, wake up via PA2(WKUP3) or RTC wakeupI follow Doc RM0377 page 869 (to update PRER) , page 870(to update CR)If I write : RTC->CR =0x00000404U; ( WUTE=1 b...
Hello, i try to configure a STM32H7S7L8H6H in CubeMX and it seems that, when Ethernet RMII is configured, SDMMC2 is unusable because there are some pins like PC1 which can't be remapped. Can this be true?This chip is designed for external memories an...
Hi, I am having a problem with a unexpected restart.The first time I use the I²C bus by invoking HAL_I2C_Master_Transmit, the MCU restarts after reaching this line:line 7276 of stm32g4xx_hal_i2c.c/* update CR2 register */MODIFY_REG(hi2c->Instance->CR...
Hello STM Comunity, I am making this post because I have reviewed many reference schematics for the use of the STM32F103C8T6, and in most of them, I see that they use 20pF load capacitors for the LSE circuit.The datasheet literally states that the va...
Hello Forum,I have an issue while reading the values from ADC. ADC1 is running in "continues scan convertion mode" using DMA and 5 ranks.Here is ADC_Init function:static void MX_ADC1_Init(void) { /* USER CODE BEGIN ADC1_Init 0 */ /* USER CODE E...
Hi there,I am using an STM32 G4 MCU for my project, and the FPU is enabled for this project. I need to implement complex floating point calculations in different ISRs with different priorities. Are there any potential risks associated with doing this...
Hi. When utilizing a 24-RGB interface, should each individual signal line be equipped with ESD protection? This would demand a small army of TVS diodes/arrays, which is fine, just want to make sure that this is an industry-standard approach.Thanks.
I am working with the internal temperature sensor and the VREFINT channel on the STM32L1 series. When I attempt to read the TS_CAL1 and TS_CAL2 calibration values from the flash memory, as specified in the reference manual, I either receive 0 or find...
hello evryon im facinsg problem with rtc hak function , il using stm32L031 in custom board . i want to use RTC wake up timer to exit from stop mode evrey 20 s , but it dosnt work and in debug mode it get ca reste fige dans la fonction HAL_RTCEx_Se...
Hey Octospi experts,I just got an external quad-SPI SRAM (AP6404L-3SQN) running via the H723's Octospi.At least mostly...No HAL use, only direct register settings (except for writing via DMA, still using HAL_MDMA_Start_IT() to trigger the transfer).R...
