I'm using a Portenta H7 from Arduino. It hosts the STM32H747 microprocessor. I was wondering if it is safe to use +5 volts for I2C even though the MPU runs at +3.3 volts? To clarify, on how the Portenta H7 is wired up, I'm using the pins associated w...
I am quiet new to STM32 programming and can't get the external interrupt to work.I started with the NUCLEO-L011K4 and wrote my programm without any issues. I switched to my own board (pdf included) and weren't able to get extrenal interrupts to work....
Hi All,I would like to configure my ADC such that it is able to read from 2 channels. And that the conversion of the channels will be stored in the memory through DMA. But most importantly, I want the conversion to be triggered by a TIMer's rising/fa...
HI,I am using stm32h743 controller and trying to port http webserver application which was working on stm32f7 platform. the application is using socket based apis. here i am generating the code using stm32cubeMX with STM32Cube_FW_H7_V1.9.0 package. A...
I am trying to change from using a Timer PWM controlled outgoing bit stream to an SPI controlled outgoing bit stream. It would be very nice to output a 32-bit word in one shot using the 4-byte FIFO at each TXE interrupt, but the RM seems to indicat...
Hello everyone, I am working on our project based on STM32H757I-EVAL board (or NUCLEO-H755ZI-Q). I have already tested several parts that we expect to use Ethernet, UART, I2C, IOs, LCD, LEDs, etc. I have troubles with LwIP TCP/IP stack and finally I ...
Hi,I have been working on my Custom STM32F405 Board. I have been using different Communication protocols like I2C,SPI2,I2C1,USB OTG on the same chip in a single code using FREE RTOS.However, I have a problem with SPI1 of STM32F405. I'm trying to com...
Hi,Connect a 32-bit PSRAM to FMC bank 1.For single WRITE ACCESS, I understand that FMC D [31: 0] and FMC NBL [3:1] are determined by the AIX data size and bit1 and bit0 of the Memory map address, is that correct?PSRAM WRITE ACCESS (single transfer)...
I am using STM32F407ZGT6 and configured the TIM1_CH1 to trigger DMA2 to transmit data through GPIO. Since the protocol is using both raising and failing edges, I need to control both data pins and the clock pin. So the TIM1 is just generating PWM sig...
