Is it available using memory mapped mode with parallel NOR Flash not QuadSPI memory?
Our R&D team is trying to use more memory for GUI with STM32F469I.We found the way using QuadSPI interface from the document as below.Unfortunately, the hardware already has completed with parallel Nor Flash memory, S29GL128S-16MB.Is there any other ...
Resolved! How to solve the USART1 receive data via RXNE Interrupt problem on STM32F769NI-disco?
My STM32F769-disco is connected via built-in st-link 2.1 to my computer. I use the bypass USART for printf(). And that works OK for output data, whereas input data stuck before they come to USART->RDR and do up the RXNE flag indicating an interrupt.H...
Resolved! program stucks when scanning 2 i2c (hi2c2 and hi2c3) using for loop
I am using STM32L072RB MCU.I am trying to scan the devices connected to i2c bus (i2c2 and i2c3)following is my function#define DEBUG 1 void i2c_scan(void) { uint8_t *p_data; uint16_t addr_scan = 3 ; printf("I2C3 Address : "); //scanning ...
Hello Everyone! I'm new to Microcontroller and I don't know where to start?
I bought a STM32F407VET6 Microcontroller board, but I am new to Microcontroller world and I never used other Microcontrollers board before. >>> Now, I am studying Electronics Engineering. I like to start with STM32 board but I don't know where to beg...
SMBUS/ PMBUS Expansion Package
I am trying to implement the PMBUS on STM32 processor using SMBUS/PMBUS exapnsion package. I am able to execute the read and write commands. But when I am trying to execute the READ_OR_WRITE command for read operation then I receive only FF FF in the...
why current consumption in low power sleep mode(LP SLEEP) on stm32G071RBT6 is around 1mA, not less than 100uA as spec?
I'm working on NUCLEO G071RB board to measure current consumption MCU STM32G071RBT6 in LP SLEEP mode. I run the example https://github.com/STMicroelectronics/STM32CubeG0/tree/be65d071640424445aa265e8b9a058e44b8decb7/Projects/NUCLEO-G071RB/Examples/PW...
How to generate sinewave by using DAC in stm32h745xg ?
we are using stm32h745xg and I initialize DAC with timer 6 ,we enable DMA also.we are using following code static TIM_HandleTypeDef htim; TIM_MasterConfigTypeDef sMasterConfig; /*##-1- Configure the TIM peripheral ##################################...
Hi, I am completely new to STM32 MCU programming. I am trying to make a simple variable frequency complementary square wave generator with my STM32F103C8T6 blue pill to drive an inductive load. I'd like to use a potentiometer to vary the frequency.
Frequency range I'm looking for is from 60 kHz to 200 Khz. Here's the code I generated with Cube IDE. It initializes the GPIOs, ADC, and PWMs but I don't know how to integrate a potentiometer in this code and be able to vary the frequency of the comp...
