Resolved! Communicate between two STM32 I2C
Hi, My objecive is to be able to communicate between two STM32FR302R8 thanks to I2C protocol. I've seen a code that should be used but I don't know which is the adress that I have to write: HAL_I2C_Master_Transmit(I2C_HandleTypeDef *hi2c, uint16_t De...
Resolved! Octospi multiplexed hyperbus on STM32L4R9 with STMCubeMX
HiAccording to the datasheets, the STM32L4R9 LQFP100 devices should be able to support a multiplex hyperbus ram/flash device. (for example the cypress S71KSS12SCO)But in STM32CubeMX, I'm unable to select the multiplexed hyperbus mode. I notice that...
Virtual Com Port doesn't work in win10
I have the stm32f4 discovery kit. It's true, natively doesn't have an UART communication from USB but I connect the pins RX and TX of debugger to USART2, step and step from datasheets. I would have to see the device in the port on my Device Manager ...
FMC SDRAM communication continuously working (even when not used)
Hello,I want to improve the electromagnetic compatibility of my design and it seems that the worst part of the circuit is the STM32H7 <> SDRAM IS42S32800J-7TLI communication.After a day in a specialized lab I know that I am out of the CE range : I ha...
Nucleo STM32F411 pins not working when alternate functions
It seems that I'm having problems with the pins configured as alternate function.If I configure the same pins used by SPI or USART as simple gpio outputs, I can see them toggling with the logic analyser. but when I configure them as SPI (alternate fu...
Resolved! STM32H723VE dma don't work with adc
dma don't work with adc. After first writing dma set flag TEIF. Value wasn't written to buffer. I ported example (adc dma transfer) from stm32h743 to 723, it have this error too.
Resolved! Why OCTOSPI registers aren't accessible on NUCLEO-L4R5ZI-P?
Hi,I'm trying to configure manually OCTOSPI registers in order to implement Hyperbus protocol but when I try to write registers it has no effect...I'm using that command: OCTOSPI1->CR = OCTOSPI1->CR | (0x1 << 0);But the register keep it's value 0.
Blinking LED with TIM1(STM32F3DISCOVERY) through registers
I'm working on a project with an STM32F3 MCU and I've been running some test-code on register level, but I have had trouble with the timer and making pin PE8 blink. The result from this code is that it will turn the LED on but it won't toggle the pin...
