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...
Hello, I use STM32F746 , touchgfx, SDRAM, NORFLASH in my project. I use MPU and I make configurations in CUBEMX and I have MPU_Config() funciton in my main.c. I wonder that; is MPU one time programmable after reset or can I reconfig MPU during runt...
Hello Community, I am using a STM32F411, 2 timer with global interrupt and preemption priority of 0 are executing a timing critical process to bitbang a GPIO port.4uS timer periodAnd a I2C DMA process to update a SSD1306 screen I2C and DMA interrupt ...
i have done the dmx512 receiving in the stm32 but now i am trying to make it robust , when i connect disconnect the cable many times the data in my buffer changes for a second which effects in the flickering i am using the framing error methoodi will...
