1-bit SDIO SD Card Interfacing problem in f_open() function for STM32F4 Discovery Board
Posted on July 25, 2016 at 19:21 Hello, I am using CubeMx to generate 1-bit SDIO SD card code. I have done so much programming using CubeMx and all those codes workfine. But When I generate SD code it is giving error (Hard Fault) at the func...
STM32F373-EVAL board,SDADC used with PT100 problem
Posted on July 18, 2016 at 16:39Hi,In STM32F373-EVAL board,SDADC is used to measure temperature with PT100 as sensor.The circuit is showed below.These two pictures are screenshots of tutorials of STM32F373-EVAL board.The document says the gain of op...
Using STM32F103 to generate 1 millisecond interrupt
Posted on July 25, 2016 at 23:20 Hello, trying to generate 1 millisecond interrupt using TIM4 timer with in STM32F103 series of processor. By selectinghtim4.Init.Period = 1 able to generate Two millisecond interrupt. When we configurehtim4.Init.P...
DMA to PWM triggered by timer
Posted on July 25, 2016 at 01:25Hi, Using cubeMX I have implemented a timer triggered (42KHz T2 TIM_TRGO_UPDATE )circular DMA transfer from ADC channel 1 to memory buffer. I am trying to do some audio processing in real time. Also I am driving ...
GPIO Alternate Input
Posted on July 25, 2016 at 14:34When we setup a GPIO pin for Alternate function, their is only option for Alternate function output. Even if some alternate functions are actually input to the peripheral (like USART_RX, Timer Capture Input etc). Even...
DAC DMA underrun interrupt on STM32F4-Discovery
Posted on July 25, 2016 at 13:54Hi. I have problem with finding interrupt subroutine which Is called when DAC DMA underrun interrupt event happen. There isn't any DAC IRQ in which I can check status like this: if(DAC_GetITStatus(DAC_Channel_1, DAC_I...
STM32F7: CAN2 Wrong Filter ID (FMI)
Posted on July 25, 2016 at 16:20Hello all,I am using both CAN on my device. It is all working well except that I am receiving in HAL_CAN_RxCpltCallback() an incorrect ID value for all my CAN2 filters. I have 6 filters on CAN1 from 0 to 5 and 6 fil...
How can I have 4MHz I2C signal ?
Posted on July 25, 2016 at 03:50I know that I2C's official speed is 100KHz (Standard Mode), 400KHz (Fast Mode), 1MHz (Fast Mode Plus).But, in my lab application, I need to implement 4MHz I2C signal. I had used FPGA logics to achieve 4MHz I2C signal....
UART under noise: data still usable?
Posted on July 25, 2016 at 14:46Hello, I'm trying to find out how UART received data is influenced by noise. STM32F1xx reference manual states that the UART will check three sampled values from the middle of each bit. If one of those three values di...
