Can't make SPI work via DMA. STM32H7xx HAL.
Hello!Trying to launch SPI via DMA data transfer to LCD display. I has created "default" project via cube master.Created SPI2 for LCD display in 8bit Master Transfer Only mode.Added DMA1 Stream 0 to SPI2_TX Mem to Perif.In code I do:static uint8_t bu...
STM32F051R4 - timer capture input value when not selected as an input
I have question about value of the TIM2_CH1 and TIM2_CH2 if they are not selected by any pin in AFR registers. Is there "default connection" or they are left floating or they are grounded?I need to know this as I cannot use these two inputs on any pi...

Weird issue in SPI HAL Transmit
I'm having a very strange issue. I update an OLED screen using SPI DMA.The OLED itself is organized as 8 rows, 128bytes each.I use the DMA to send framebuffer chunks containing the data (128 bytes) for one row.When the callback is called, it checks i...
Resolved! What information stores in the .bin file and where exactly they are stored in stm32 firmware?
I want to keep 2 application files inside the flash and jump to either using a command. When using the STM32 cubeIDE for development, the .bin file is generated under debug folder. I couldn't find the .hex file though. I want to know what is the meta...
Resolved! STM32L476VGT6 problem with sending commands in QPI mode
Hi,I’m using STM32L476VGT6 device with external flash memory in QPI mode. Everything works fine until I try to send a command byte with no address and no data. For example, when I try to send the command 0xF5 (exit QPI mode), on the logic analyzer I ...
Resolved! STM32L1 RTC interrupt using EXTI20 and wake-up from sleep mode
I programmed the STM32L151RET6 to gives the RTC interrupt using line EXTI20. The system is waking-up from sleep mode at every second, it execute a small code and left the interrupt. For example:void RTC_IRQ_Handler(void){ // { my code here } // ...
ADC read from multiple pins? STM32F411
Hello,I'm using cubeIDE for the whole setup and I'm trying to read a voltage from 2 different pins now when using:HAL_ADC_Start(&hadc1); HAL_ADC_PollForConversion(&hadc1, HAL_MAX_DELAY); ADCPin1Val = HAL_ADC_GetValue(&hadc1);where hadc1 pointer ref...
