Hi have been working on the interfacing of ssd1327 with stm32 microcontroller, i am just trying to print a pixel on the display but I could not display it. my code is as follows WRITECOMMAND(0xae); // WRITECOMMAND(0x15); WRITECOMMAND(0x00); WRITECOMM...
Hello! I am utilizing discover board STM32F407 with FPU , The board is ARM cortex M-4 based. I want to use FPU to quick the process of conducting exponent calculations and Floating point. I have set down all peripheral drivers that are required for a...
Hi, I'm developing a motor project using stm32f429. But my pro can hit the HAL_TIM_IRQHandler() interrupt function but the status register is not normal when tim2 capture XORed input signal. The TI2's CC1IF is set when hit the interrupt function but ...
I try to learn how to use OPAMP by testing the example code Examples/OPAMP/OPAMP_PGA/.The MCU board is Nucleo-G431RB.This is the case of OPAMP_PGA_GAIN_2_OR_MINUS_1: blue line is output by DAC and red is by OPAMP. My 1st question: why the amplified s...
I'm mounting my MCU on PCB. I have done the schematic referring from https://www.st.com/resource/en/datasheet/stm32l476je.pdf . Please help me verify this. My conditions are as follows.I am using 2 Digital sensors and one LoRa as communication module...
STM32G474RC，flash size is 256kB，default dual bank，so the flash size is 0x08000000~0x08020000, 0x080400000~0x08060000.If the code size is larger than 128kB, but the address is non-contiguous. How to store the exceeded programs into Bank2 automatically...
Hi, I'm working on an STM32H7 project with very fast (800 KHz) periodic interrupt. I've been looking at the generated code as I tweak the C source. I'm confused about the use of "volatile" for the global variables used by the ISR.I feel like I need...
stm32f103cbt6, i2c1 in slave receiver mode. CubeIDE, stm32f1 pack ver 1.8.4. I use HAL_I2C_Slave_Receive_IT to receive 1(adr)+2 bytes. I2C standard mode. Both err and evt interrupts enabled. I2C stucks into bus error (BERR flag). Jumping over HAL co...
Hello, is there a way that a timer triggers an I2C-Receive with a Datatransfer from the Peripheral to memory via DMA?I’d like to have no “Timer-Interrupt�? that calls the DMA-Transfer, invoking the I2C. I’d like to drive the DMA-Request from the Time...
