CASE 1:I am using sdmmc for SDIO bulk transfer at 400khz initially then switch to 25 mhz.Its not working with nucleo h743/53 where cpu frequency 480 mhz and sdmmc input clock is 480 mhz.Its working with nucleo h743/53 where cpu frequency 480 mhz and...
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 ...
Hi,We have STM32N6570-DK and are testing camera input, video encode and write to SD cardWe have not been able to make the "VENC_SDCard_Appli" example work, the SD card just contains zeros.The "VENC_SDCard_ThreadX" example does work however, resulting...
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
Hi everyone.I'm using the STM32U073Mx / LQFP-80 pin.While designing a schematic, I ran out of ports, so I'm curious to see if I can use the VDD (battery voltage) to VBAT pin trick to measure the battery voltage. I'm looking at the datasheet and refer...
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...
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...
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...
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 ...
