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...
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...
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 ...
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 } // ...
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...
Hello, All!When I try to uninstall "windows driver package - STMicroeletronics (usbser) Ports (01/03/2015.1.1)", I get an error message (see attachment).Can you support me?
I'm using the STM32L031 and Low Layer code, generated with STM32CubeMX (lateset version)If the selected oscillator for the RTC is not LSE (e.g. after poweron) the code generated with STM32CubeMX will disable the LSE via a ForceBackupDomainReset rig...
I am a beginner in embedded coding, I am trying to turn on user LED's of nucleo-l4r5zi board but its not turning on. kindly lead me to the solution. (I am using keil)Thanks.Code:#include "stm32l4xx.h" // Device headerint main(void){RCC->AHB2...
HiI need a big heap for some json parsing. How do I re-locate the heap into SDRAM? Obviously this needs to happen fairly late in the initialisation sequence once the SDRAM has been set up and initialised.Is there an equivalent of __set_MSP() ?Thanks
