Looking for examples of LIN communication on STM32u5 microcontroller
Could anyone share a project using LIN communication on an STM32u5 microcontroller with me? Thank you in advance!
Resolved! STM32F405 internal temperature sensor problem.
Hello everybodyI have a problem with reading of the data from the internal temperature sensor. I'm using last Cube IDE and Cube MX for configuring the project.I created the project according to this example: "Get temperature from STM32 internal tempe...
How to generate 32.768khz STM32F103C8T6 bluepill for Max30003 sensor?
There is MCO that supports PLLCLK, HSI, HSE, SYSCLK but not LSE with 32.768khz. How can I produce this frequency for FCLK pin of Max30003 sensor? Do I need use Timer? If yes could you send me some examples how to do it properly?
SRAM Retention in Standby Mode with STM32G0 Value Line (STM32G0x0) MCU using un-document RRS bit 8 in PWR_CR3 register
There are conflicting things written in STM32 documentation regarding SRAM retention during Standby mode with SRM32 G0 MCU.For example, in RM0454 G0 Reference Manual it states two different things 1 paragraph apart .The UM2319 G0 HAL/LL Manual has a ...
Resolved! Interrupt Time Base Generation in interrupt mode fails
Hi all,im trying to bring a timer interrupt to work. In the first step I want to create an LED blinky.For that I followed the instructions from the Knowledge base example (How to generate a one second interrupt using an STM32 Timer). The only differe...
Resolved! stm32f302r8 i2c problem
hello i am working with i2c i used register for coding i2c but when i configure AFRH register i cant upload my code to my board i have target not responding error then i tried hal library but nothing changed
Resolved! Power on reset (PORRST) not detected on STM32L471RGT6
Hi, I am trying to detect whether a reset event was caused by power on rather than any other reset such as a button reset or a software reset. I attempted to use if (__HAL_RCC_GET_FLAG(RCC_FLAG_PORRST) != RESET)but the compiler reports that PORRST ...
Resolved! Do the G4 series contain a DMA on timer break feature?
The RM0440 ch. 28.3.18 rev7 mentions on page 1128:> An interrupt is generated if the BIE bit in the TIMx_DIER register is set. A DMA request can be sent if the BDE bit in the TIMx_DIER register is set.Unfortunately, the DIER register does not contain...
DCMI and PSSI HAL DMA routines are not using half complete callbacks, but it is possible.
Hello. I've noticed that DCMI/PSSI code does not provide this functionality, but it is very handy when using DMA in circular mode (ADC, frame buffer pumping to other interfaces, etc.). I've tested DCMI+DMA circular mode on F4 and PSSI+DMA circular mo...
