Hi, we are working with a STM32F217 and the RMII bus.In the two documents reported I see an inconsistency on the diagrams (on the one hand rising edge sampling, on the other falling edge). Which one is correct for my chip?RM0033 Figure 328 Reference ...
Dear allI'm starting a design with the STM32L412R8I (or maybe STM32L412RBI6) and I cannot find the VBUS dedicated pin in the datasheet nor in the manual. In this design the USB will be always device (no OTG)Is it enough to have VDDUSB powered to de...
I'm using ADC1 to measure the Temperature Sensor channel and the Vrefint channel. I expect those to vary very slowly and I am in not in a hurry so I am maximizing the sampling time. These are my settings in STM32CubeIDE:It generates the following in ...
This is a question about SPI communication.There is an NSS pin for SPI communication, but is it okay to use GPIO instead of the NSS pin when there is one master and one slave?We don't quite understand the role of NSS. I think it will be useful when t...
Hi,I am using an STM32U545 on which I expect to use ADC4_IN1 and ADC4_IN18 in stop mode 2 (using LPBAM).I want to create two buffer (buff1 and buff2 uint16_t[32]) dedicated to each input.I want to read 32 samples from input1 then 32 samples from inpu...
Hello Dear Community,I am working on an HMI System and using STM32H7B0 with APS6404L-3SQR. I am able to do all operations including Write in Memory Mapped Mode but when I try to write 1 byte, It writes 8 bytes which is not what I expect.I have read m...
Hi Community,During a project we are using the microcontroller STM32H7B0RBT6 with QSPI PSRAM APS6404L-3SQR , it works fine in indirect mode either in quad read and quad write, but the issue is with the write in memory mapped mode when trying to write...
The STM32H7 reference manual (stm32h723zg.pdf) contains several tables describing he pin mappings (pin to functions).In Table 7 and 8, for pin A0, A5, and A15, it lists the pin function as "TIM2_CH1/TIM2_ETR" for alternate function #0. Should this be...
Motivation: Release a product (STM32F072RBT) with no buttons or toggles on the PCB and allow customers to flash and interact with their product over USB serial interface. Requirement: Keep BOOT0 held high so the STM32 is in DFU mode upon initial conn...
Hi all, I currently work on STM32F030K6 . I am working with a reed switch connected to pin PA8 (EXTI8). I havec onfigured the PIN like : "external Interrupt Mode rising/falling ....I need to perform an action on the rising edge AND on the falling ed...
