STM32C011J6M6 single-wire USART (STM32CubeMX/IDE getting-started question)
Need getting-started help with STM32C011J6M6 MCU and USART1 in single-wire Async mode (using STM32Cube toolchain and C language.)The hardware configuration is just the STM32C011J6M6 MCU (8-pin SOIC package) with one pin (pin 1) pulled up (4.7K to 3....
Resolved! USBx MSC demo not working on stm32h5 discovery board
I've just brought the stm32h573i-dk dev board and what to become familiar with Threadx and USBx. I have a uni project coming up that I would like to use the board as a msc device but struggling to get the board to enumerate with the PC. I have tried ...
Resolved! STM32U073CCT6 and using LPTIM to wake up the CPU from STOPMODE2
Hi I'm trying to use an LP TIM to generate an interrupt after a time interval on an STM32U073CCT6. The interrupt will wake the processor from STOPMODE2.I haven't found any examples, and the STM32CUBE MX doesn't have a software-triggered single-shot o...
Is there a way to decode picture (1920x1080) within 50ms?
We use STM32H743 to develop a system that needs to display a 1920 * 1080(8-bit pixel depths) graphic on LCD(driven by FPGA)Now our design is that STM32 reads a picture from the SD card, then decodes and sends it to the FPGA through FMC.We tried the s...
STM32F417 to STM32F437 - is the AF mapping identical for pins present in the 417?
This previous thread refershttps://community.st.com/t5/stm32-mcus-products/stm32f4xx-does-going-up-a-package-pin-count-impact-pin-af/td-p/862282The 437 is curiously a very close superset of the 417. Apart from the extra 64k RAM, the only difference i...
Possible Future Video Decoding (H264 Decoding) on the STM32N6x7 MCU
HiWe're looking at an application where it may be helpful for an STM32N6x7 MCU to encode and store video from an ST image sensor then later recover and decode the video for analysis by the Neural-ART Accelerator in the STM32N6x7 - encoding and storin...
Resolved! Problem of porting FreeRTOS to STM32H573I-DK by CubeMX
Hi everyone,I have a STM32H573I-DK and try to port FreeRTOS without TrustZone to this board by CubeMX but suffered from a problem.I installed the X-CUBE-FREERTOS, set TIM17 for HAL Tick and SysTick for FreeRTOS.It will block (or crash?) in vStartFirs...
STM32F446 EXTI GPIO interrupt not triggering
Hello, I’m working with an STM32F446 and have configured GPIOB pin 12 as an EXTI input. After initialization and before entering the main while loop, I call a function that blocks program execution(what I mean by blocking : I have a test that stands ...
Resolved! STM32F4xx - does going up a package pin count impact pin AF mapping?
I think it doesn't have an impact and you just get extra pins (e.g. extra SPI controllers becoming accessible) if going say 100 to 176. But it's not clear...IOW, will existing code run exactly as before? Isn't the silicon identical and they merely bo...
