Hi,STM32H533 datasheet (DS14539 Rev 2) in table 88 says that RDY input setup and hold time are both 0.5ns. From my naive point of view it looks like superb value (RDY have to be stable only +-0.5ns around CLK edge). Isn't that a typo ? (STM32H7 PSSIs...
Hi, i'm developing a board with 7" lcd (LVDS) so i'm really hesitating about if is right to use a SN65DSI83 for this, my STM32F469IIT6 only have 2 DSI Lanes. I'm connecting the i2c lane from SN65DSI83 to i2c of STM, i just copied the circuit of cm4-b...
I am currently choosing an LSE and HSE crystal for an STM32H743 project. AN2867 includes tables of compatible STM32 crystals. There is also a crystal selection tool from ECS which i've used. My question is, after selecting a crystal from the tables, ...
The USB Host seems to not work if WFI is executed in the FreeRTOS Idle task. Is it not possible to use USB with a WFI Core sleep?Thanks for any insight. A forum search yielded mention of similar problems on other devices (over years!) but no defini...
I'm asking because I've done the steps shown in the screenshot. But, many libraries are missing!
In my application, I have a watchdog timer that resets every 45 seconds if not fed. I also have an RTC. The application records sensor samples, along with timestamps from the RTC.Problem is, when there is a watchdog reset, the RTC is re-initialized t...
Hello everyone,I hope you’re all doing well! I’m currently struggling to get one of the directly connected ADCs on the STM32H723ZG working at 75 MHz, which is the maximum sample rate according to the datasheet.I’ve selected ADC3_INP1 since it’s suppo...
I am using STM32F410RB Nucleo Board for my developement. When I am creating new project chossing the same board STM32F410RBTX_RAM.ld Files is Missing. Due to which I am not able to flash my board and getting error.On the other hand I tried selecting ...
I have configured the comparator 2 PB6 on the STM32G071RB Nucleo board. It is configured for rising edge interrupt. As soon as HAL_COMP_Start is called on the COMP you can see the EXTI rising edge interrupt flag immediately go high. (well not immedi...
Hello,We have run into some issues regarding SPI in interrupt mode, especially when building with optimizations turned on. We are running SPI at 21MHz.The situation:We transmit one byte using HAL_SPI_Transmit_IT. This immediately triggers a TXE inter...
