I can easily retarget the printf and is working perfectly, but it is receiving nothing from the com... Yes, I know, there is a lots of ready and available OSes for STM32 Cortex-M3, -M4 and sometimes -M7. Yes, I know, there is a support of STM32 chips in mainline kernel. Yes, I heard about Emcraft. Yes, I got my... STM32F437 processor I have no experience using the stm32 timers with DMA so I wish to solicit suggestions before banging my head against the wall. I have set up a counter using an ISR to count pulses (RPM) an... When an SPI in SLAVE is clocked continuously (with NSS active) and DR is *not* written upon every TXE set, there are several possible scenarios for MOSI behaviour after the last explicitly written data bit is transmit... This is supposed to receive one byte in SPI bidirectional mode ([STM32Cube_FW_L4_V1.5.0]\Drivers\BSP\STM32L476G-Discovery\stm32l476g_discovery.c): #if defined(__ICCARM__) #pragma optimize=none #endif /** * @bri... Good morning, I have a problem with the declaration of an array. if I declare these two arrays before the main I have no compilation/linking problem uint16_t buffer ; uint16_t buffer2 ; but if I... Can not set the input frequency value of quartz LSE/HSE - after entering the frequency value and loss of the input focus, the frequency is divided by 1000. The division is repeated if you return and remove the input f... I tried to upgrade my working project, ad the result is project unusable ! The SD part is impossible to use, missing definitions, missing functions and others problem. Its possible to downgrade cubemx ... Hello, I need to configure the parameters of timer TIM6 inside the STM32F769 to trigger the DAC output. The triggering time is variable and must be set depending on some parameters sent to the MCU from a PC. The mi... I ultimately need "instant on" ADC conversions. For instance, when a timing gate goes high, I need to start taking ADC values immediately (the signal is only 100us wide), The problem I'm running into is th... Hi, I'm using Nucleo F207ZG board and i did my testing of GPIO using STM32CubeMx(HAL lib) with Eclipse IDE on Ubuntu 16.04, Now i want to use the USB as Communication Device Class (CDC) but i'm not familiar with usb s... Hi! I've just recently checked AN2606 Application note that is a document summarizing STM32 devices bootloader features, requirements etc. I have not found STM32L475xx series listed in the document, however the d... I think that there is dangerous a bug in the cmsis_os implementation, because when you create a queue (thru osMessageCreate), it creates a queue in FreeRTOS with the item size based in the item size configured by the ... Hello, I have been trying to solve problem with the osMessagePut function from CMSIS-RTOS wrapper. I am not able to insert instances of C structure into the message queue. My co... Hi, In my application I'm using the Independent watchdog on a STM32F407 with a maximum reload period of 2 ms. During some maintenance operations, we need to save some configuration parameters in flash memory. ... The new format of code generation makes a BUG in the file: bsp_driver_sd.h The BUG prevent building FAT_FS modules To solve the issue line 67 should be changed with the following ones: #ifndef BSP_SD_CardInf... i search in google and i can't find any adc external trigger example code i found timer trigger only. i want adc start conversion when external pulse found. i want any example code I am trying to fetch the RAW image data from the OV5640..I can successfully receive the JPEG image but I can not configure it for YUV RAW data ? I have configured it to receive Black and White and Negative image which... Hi, i'm using stmcubemx 4.19.0 for my project on stm32f415vgt. But i think it's present a little bug inside cmsis_os.h When i create queue, the item size is never 0x04. #define o... Using STM32Discovery on IAR. I expect TIM2_IRQ to fire up on trigger from outside. It does but CH2 interrupt ic leared and all other 3 IC interrupt bits are SET. Why?
