Timer 2(32 bit timer) in running mode to provide timer tick at 1ms. controller - STM32F072VB timer - TIMER 2 mode - up counting mode This timer should get TIm->CNT increment at 1 ms. then what should be the prescalar??
here is settings i did..but little bit confused about prescalar valuestatic void MX_TIM2_Init(void){ /* USER CODE BEGIN TIM2_Init 0 */ /* USER CODE END TIM2_Init 0 */ TIM_ClockConfigTypeDef sClockSourceConfig = {0}; TIM_MasterConfigTypeDef sMasterCon...

SetRange problem in X axis
Hello, I've wrote SetRange in a graph like SetRange(0, 50, 0, 50), but the problem is my graph is stretched an i want have it in a compressed look. So i changed it to setRange(0, 100, 0, 50), but my x axis was shorten to 1/4 and rest of my X axis rem...
SD card write using SDIO (4 bit) with DMA enabled is making system fail. I suspect cyclic write of around 200 bytes at 100 Hz is leading to bus contention issue or so.
Am using sTM32F4 Discovery board with extension board for RS232 interface and SD card.RS232 is also using DMA and its priority is higher than that of SD card DMA channel priority. The tasks working on RS232 interface and SD card log are different to...
Resolved! Reading from Accelerometer via i2c on STM32F3 Discovery
Can anyone tell me the difference between those functions:HAL_I2C_Master_ReceiveHAL_I2C_Mem_ReadThe problem with HAL_I2C_Master_Receive is that it accepts too few parameters (hi2c, DevAddress, pData, Size, Timeout).I don't know how to tell the memory...
Lots of ADC Noise with STM32F103RBT6 and STM32F103C8T6
Hello,i'm doing my first project with the STM32F103, where ADC is involved.I want to read out several potentiometers and send MIDI commands to a PC.So far everything is working, but there is soo much noise on the ADC data. I'm using only the upper 7 ...
Resolved! From where can I purchase STM32F407G-DISC1 board ?
I"m new to ST website. I tried purchasing this board but I could only find older board. I need to purchase this newer board.
[STM32F072] Problem in use all 4 UARTs in same time
I am creating a hub to connect several devices together. When I send a frame to one of the UARTs from an external device, I get an interrupt from each of the UARTs instead of just the one I sent to. what i am doing wrong?I generated configuration in ...
QSPI missing first nibble
HiI am using the STM32F723 to read FPGA with the (notorious) QSPI interface in a custom board.The QSPI is configured to indirect read mode, 4 bits, using DMA.The issue is that the first nibble is not read. All other bytes are as expected.The Errata s...
