Posted on November 17, 2016 at 20:02I'm on an STM32F4 and using an RTOS. I put the MCU to sleep whenever the scheduler has nothing to do using the WFI instruction. I'm using DMA1 with i2S and a USART. I want to disable the DMA1 clock using the RC...
Posted on November 17, 2016 at 18:22 Hello In stm32L1 Cube lib 1.6. In the interrupt handling of a transfer complete on i2c in slave mode with DMA, the HAL_DMA_IRQHandler(...) calls XferCpltCallback(...) which points to I...
Posted on November 16, 2016 at 19:42 Hello there, I was trying to get going with ModBus RTU communication on the STM32F030 chip, specifically the t3,5 interval counting, since its supported by hardware in this chip (RM0091 page 701 on the bo...
Posted on November 02, 2016 at 09:25Hello all.I've got a problem using I2C1 module on STM32F030K6 MCU. Everything works properly until I enter ESD exposure to the pcb. This leads to I2C hanging, but other parts of MCU continue working.I tried to res...
Posted on November 17, 2016 at 12:57Hello, The STM32cubeMX code generator labels as FreeRTOS the RTOS functionalities, but the code generated looks compliant to the CMSIS-RTOS API. The directory Middlewares\Third_Party\FreeRTOS\Source contains the s...

Posted on November 17, 2016 at 13:39I'm unable to program the option bytes from user software. In an STM32F103RGT7.Erase works, program does not.Code:// Lock and unlockFLASH->CR = FLASH_CR_LOCK;if( FLASH->CR & FLASH_CR_LOCK ){ // Unlock fpec ...
Posted on September 07, 2016 at 23:27Hi, I wonder if there is any chance for stemwin 5.30 or newer in near future ?Thanks
Posted on November 14, 2016 at 21:35Good day,What I want is: If I put GND to GPIOD_4 I want to LED ON.If high impedance then LED OFF.I attached my schematic with CHRG pin connected to GPIOD_4.Is it possible to pull up internally gpio?I wrote some co...
Posted on November 16, 2016 at 13:18We are trying to implement Position Independent Code (PIC) on STM32F479NI. We have used -fpic and -msingle-pic-base options while compiling the code. Initially we wanted prove that this PIC concept will work on a ...
