What is the reason for have two SRAM in the STM32L476 microcontroller?
I'm learning about the STM32L476 microcontroller and saw that it has two SRAM memories. What is the reason for that? I also see that it's possible to enable parity check on SRAM2. How come, is SRAM2 unreliable?
stm32f7 as spi slave
Hi. I am trying to work with AD7763. I have the same problem as in this article, but there are no answers in it. https://community.st.com/s/question/0D50X00009Xkfaw/spi-oneway-communication-slavemaster?t=1639997683527So AD7763 is master and stm32f7 i...
Hello, I am making a CUSTOM HID Keyboard application with the stm32f103 processor, when I add the media keys (volume reduction, increase, etc.) to my project, the function that reads the status of the following leds with event_idx does not work. HELP!
this is leds status code ;static int8_t CUSTOM_HID_OutEvent_FS(uint8_t event_idx, uint8_t state){ /* USER CODE BEGIN 6 */if( (event_idx & 0x01) == 0x01 ){HAL_GPIO_WritePin(GPIOA,GPIO_PIN_10, GPIO_PIN_RESET);}else if( (event_idx & 0x01) != 0x01 ){HAL_...
STM32F469 HID - add a keyboard to a custom HID
I have my custom HID device running and working fine. I would like it to also emulate a standard PC keyboard at the same time. So when my board enumerates, I would like the attached PC to find my custom device as well as a keyboard.I think I can ju...
Resolved! My STM32G473 has wrong flash size? How do I deal with this?
I have STM32G473VCT6 MCU. According to part number this device should have 256kB flash (Size code C). Flash size register (0x1FFF75E0) also shows 256kB (reg. value 0x100). However I can read and successfully write 512kB of data. STM32CubeProgrammer a...
Resolved! ADC Result false
Hello I need to receive the value of multiple Channel of ADC 1 I followed this tuto : https://controllerstech.com/stm32-adc-multi-channel-without-dma/But when my pin 1 is connected to GND i have 1500 of numeric value Already tested in Arduino and...
How are non-existent pins / ports wired up
Does anyone have any experience of trying to control non-exisistant pins?I have a design that takes stm32f767 in the lqfp100 package. But none seem to be available.Looking around, I managed to procure a small run of stm32f779* in the wlcsp180 package...
Related to equations solving in STM32 MCU
I am using STM32F404 MCU I have interacted MPU6050 with my MCU and now i want to put IMUs data into some Eular equations for my application I have enabled FPU of Processor and using math.h library to code the equations i have observed that its takes...
