What is _l in pin IO structure?
In the STM32L4P5xx datasheet, some pins' IO structure is labelled with _l (in combination with other letters). However, this letter is not explained in Table 14 nor anywhere else.Can this please be explained?Thanks,JW

ADC and DMA on STM32F303
Hi, I run ADC1 with DMA on my STM32F303RE with 72MHz clock. I take the number of samples flowing into the circular buffer per timeunit. I calculate a sample freq. of 1.305 Megasamples per second Ms/s. When I look at the sampled known signal I calcu...
Pin on STM32L4P5VGT6 interfering with ADC PC3 and PC2
I made a mistake and set PC2 as an ADC input and PC3 as an GPIO_EXT. The IDE does not warn you when setting the pin to GPIO_EXT, it only shows the warning in the ADC, so I missed it since the ADC was already set.The question is, is there anyway to ma...
STM32N6 DCMIPP Horizontal Distortion Beyond Certain Line Length
Hey all,I have a Sony IMX686 camera module connected to the STM32N6 Discovery Kit, streaming video to the on-board LCD. The sensor outputs a single-stream RAW Bayer format on Virtual Channel 0, and the DCMIPP receives the data correctly — up to a cer...
HAL_CAN_START returns 131072
Hi. I'm new to STM32, and I'm using STM32F103C8T6. I want to run Loopback mode to test CAN BUS without another board first. When I go to debug, I find it stuck at HAL_CAN_START. It returns error code 131072. Can you guys please help me find out the p...
STM32 N6 Load and Run USART doesn't work
Hi, I have been trying to deploy the 66GYMAI1 Camera on the STM32 N657X0Q Nucleo board with the Load and Run mode. However, there is a problem that I could not solve, which is that the project can not jump from FSBL to APPLI. Because I am trying to ...

STM32U5A9: Unable to set RTC_CR WUTIE and WUTE bits
Hello,We are using the RTC wakeup timer and I have noticed that sometimes the WUTIE and WUTE bits are not being set. We are using HAL_RTCEx_SetWakeUpTimer_IT() HAL function to enable the timer. In stepping through the HAL code, it sets the RTC_CR_WUT...
CAN Communication
I am implementing a CAN communication structure with one master and two slaves. Both slave devices perform exactly the same function, meaning their hardware and firmware are essentially identical. The master’s intention is to send commands only to a ...
