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...
I have a STM32G071 where, among other stuff, an UART interface an a GPIO input are configured. UART is mapped to PA9 - PA12 (Tx, Rx, CTS, RTS). PA8 is configured as GPIO input mode (no pull-up, pull-down). On the net connected to PA8 is a hall sensor...
1.Assembly language2.C language without HAL3.C language with HALAnd why you choose that method ?
The documentation for the DAC says "A DMA request can be generated when an external trigger (but not a software trigger) occurs if DMA requests are enabled"But I want to configure the DAC to have no trigger, and instead use TIM12_TRGO to drive the DA...
I am working on STM32H743 MCU. I generated the initialization code used stm32cubemx v5.3.0 and embedded firmware package for STM32H7 V1.5.0. I am using keil uvision v5.28.0.0.I initialized uart1 in interrupt mode. I am receiving data in buffer until ...
I am using the Nucleo-F767ZI board. I have the normally open of the switch wired to 5V.Common is to pin A0 and to R10K then pulled down to GND.When the button is pressed the pin A0 will go from 0V to ~5V.Want to blink LED1 at say 1Hz, then when butto...
