STM32H7 PSSI
Hi,I know that PSSI can be used to transfer data between two STM32H7 microcontrollers. I wonder if there are other uses for PSSI?Are there any other components that use this interface?

Switch GPIO interruption
Hi, I have 3 interruption pins PA13, PA14 and PA15, I would like to enable one pin for interruption at a time and changing the interruption mode, I made this function, but I'm not sure if it's the right way to achieve that.void Switch(uint16_t PIN, u...
STM32H743ZI2 ADC3 AND DMA
I am using NUCLEO-STM32H743ZI2. I try ADC3 + DMA, but I confuse ADC3 CLOCK, from cubeMx, I found THERE ARE 3 SOURCE (PLL2P,PLL3R,PER_CK) for adc clock, in manual, it mentioned SCLK and HCLK can be clock resource as well. In RCC adc clock selection, o...
Issue while adding padding to generated file
In my project I need to add padding to few flash address. I generated hex file which has flash data till 0x1000(Suppose) but I want to pad till 0x4000 with 0xFF. I am using below gcc commands but unable to get desired output.arm-none-eabi-objcopy --s...
Hi, I'm having trouble sending data through SPI on the STM32L476RG with CubeIDE.
In my debugging, I noticed something wierd with this line of code from HAL_SPI_Transmit macro :hspi->Instance->DR = *((uint16_t *)hspi->pTxBuffPtr);pTxBuffPtr being the Transmit Buffer which, in my case, is txBuff[1] the first element of a one-elemen...
Generate interrupt on center aligned mode at counter overflow
Hi,i am using STM32F334C6T.i try to set my PWM as Center Aligned mode and generate interrupt at counter overflow. my code as below.whatever i do in my code, i can not take just one interrupt which is counter overflow. everytime it generates two times...
Resolved! RTC backup registers after power off and on
Hi ST Community,I am using the RTC on the STM32l100RBT6 µC to display the date and time every hour. It is battery powered and therefore at some point i would have to change the batteries, therefore, the µC will lose power. I have thought of using the...

No clock signal on PA5 bit(SPI1-SCK)
Hello,I'm learning to use the SPI module. I'm using an STM32F446RET development board. I want to configure the SPI1 module and send some message 'out into the world'(this means I only have one master devices which sends some bytes and no slave to rec...
Resolved! HAL_I2C_Mem_Write_DMA sends only one byte
The blocking version (HAL_I2C_Mem_Write) works nicely, now I'm trying to use HAL_I2C_Mem_Write_DMA. Here are the settings as given in the configuration tool.The resulting code generated by the configurator (I removed some comments for brevity):static...
