I'm looking at using the MX25L3233F for flash storage. This is a serial NOR device. It appears to support QuadSPI, but it also appears to support regular SPI:"MX25L3233F features a serial peripheral interface and software protocol allowing operatio...

Greetings, I have a few STM32MP1 boards. One of which I have configures the OS on, and custom applications.I copied the SD card and put it in another one. The MAC address is the same. I read an STM article about the MAC address and "fuse sense 0 57...

Using the STM32MP157 development kit, I have configured two "GPIO Analog" lines that are exposed through CN13 (pins 1 and 2).I am trying to set these up as such. From going down the rabbit trail of documentation:https://wiki.st.com/stm32mpu/wiki/GPI...

I'm using AzureRTOS to develop on the STM32H745. I've started with the CM7 core and I've generated some basic code using CubeMX. I've selected TIM6 as a time base for HAL, since AzureRTOS will take over systick for it's uses.I've made a couple thre...

Hello, Using the stock image I've found I can manipulate the red LED on PA13 by using gpio commands:gpioset gpiochip0 13=0 gpioset gpiochip0 13=1I need to access Pin 38 and Pin 40 on the 40 pin header, which are PI6 and PF11.These are both tied to th...

The datasheet clock diagram seems to support SPI modes 0 and 3. So we'll give it a shot.

Thank you. That helped me determine what I was looking for in the datasheet!

Thank you. That actually makes perfect sense. They are all analog capable, as it's just a setting to lower power. However, to read actual analog signal they must be attached to an internal ADC peripheral. The datasheet is sparse. However, the Refer...

Thank you for your answer. I want the GPIO in analog mode to read input from it. I have looked at all those pages. I am currently using the ADC channels for a few inputs. Following those readings I did not attempt to apply those to GPIO Analog...

Sara's response is good. There are a few things to be aware of and that post talk about it.
