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...
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...
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...
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 ...
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...
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...
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...
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....
