I'm trying to send some data from master to a slave (the STM32F103C6) with HAL functions, with HAL_I2C_Slave_Receive() -no interrupt mode- the reception works flawlessly but with HAL_I2C_Slave_Receive_IT() -the one needed- the slave acknowledges its ...
Hello,I setup i2c1 as per below. I am trying to get data from a MPU6050 device on I2C but I got error code 4.On the same hardware I tested using Arduino IDE and I can read data from MPU without problems.Can one support please guide me where should I ...
Hi, I have never work with register. I need to restart counter of LPTIM in stm32l431. The documentation says that I need to set a register to '1'. The image explain this. How I can do that? Thank's a lot.
Hi,I am trying to enable DCache on a USART Tx DMA snippet, which causes USART Tx to fail.The impression that I have is that the MCU has already written to physical memory and the DMA should have no trouble in accessing the written memory ?Can someone...
Hello guys, I am working on a acoustic source localization project. I need to sample the amplified signal from Hydrophone. The acoustic source emits a sound frequency of 42khz. I need to sample this signal at a frequency of 100Khz or even 200khz(if p...
Hello,Which mcu products are provided as dies or wafer?Thanks
Hi Everyone,My problem relates to I2C communication when trying to send bytes to a display on address 0x78. First I tried with the plain I2C HAL function(blocking), but I realised that the MCU gets frozen because of the huge amount of data to be sent...
Hi, I am working on my Stm32F407 Discovery Board. I use CMSIS when I codding and I have some problems with PLLCFGR register. I want to using 168 mhz clock speed. This is my Clock Configuration code and I get problem in PLLM configuration in PLLCFGR r...
Hi ,I have a problem when using __attribute__((bitband) when using Keil IDE.However I used bitband using classic marcos#define BIT_BAND(addr,pin) ( (((addr) & 0xF0000000) +0x2000000) + (((addr) & 0xFFFFF)<<5) + ((pin)<<2) ) and it works as expected...
Hey guys, I am trying to get I2C working with DMA or without, but I am having similar issues with both. The I2C sends out the data correctly the first time via DMA and the DMA_TC interrupt is called, however it gets never called again. I can also see...
