I'm using an STM32L151 and I write values to EEPROM. I have a timer interrupt that executes at 1000Hz. But I see that the interrupt lags when I write to EEPROM.How can I avoid this? Should I place my timer interrupt handler in RAM? Would that work?
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...
Hello,I am working on Nucleoh745ziq .Its have two cores cortex-m7 and cortex-M4, how making the communication between two cores. They give the example code for that but they doesnot give the proper information, which parameter we can configure in c...
