Hello,I am using a windowed watchdog and resetting (petting) the timer in the EWI interrupt. I also kick/pet it in my main loop at 1000Hz. Time is kept via a systick handled flag. Systick, to my knowledge, is attached to the system core clock (same a...
STM32L4S5ZIT: My code is dynamically changing the AHB prescaler 1 or 2. I am using HSE external 6 MHZ crystal oscillator. So my program dynamically 6 to 3 & 3 to 6 MHZ will be changed through AHB prescaler(I am not using more than 2 prescaler). I a...
I wanted to see what would happen when I set the prescaler for an interrupt lower and lower.My expectation was that the main loop would lose out on it's share of processing time, but I was surprised when the results of my test were mixed.Essentially,...
I would very much like to know what ST work methodology?This should be thought of "of" or "of" whom to right of opining and to manage.Of course it's not me, I'm just a customer.Thoughts from engineers and managers !!!!Ok, let's get the tools you need...
Posted on March 28, 2016 at 17:23I am new to the STM32 product line and starting to write SPI code using the STM32cubeMX module. I note in the cube drivers manual that they provide both HAL_SPI_Init and HAL_SPI_Mspinit. Looking through the web and ...
I want to read data from PT1000 thermistor. After succeeding in communicating with the TouchGFX model and displaying the content I wanted, I now want to be able to read real time temp. For this job I have PT1000 sensor. I have made the ADC to work, b...
Hi all,I need to install a communication between 2 STM32H743 units (on one board) with maximum speed (10 MBit) on UART mode and I need to check incoming characters to detect Linefeeds etc. The problem is that with FIFO mode enabled (Threshold 1/8) in...
Hi all,I try to install a synchronous USART communication between 2 x STM32H743, one is the (transmitting only ) Master the other is the (receiving only) Slave. When transferring data via Polling everything seems to work well.But when using HAL_USART...
Hello, dear collegues!Please help me with I2C!I use I2C to transfer data between 2 controllers: STM32F051C8T6(Master) and STM32F100C8T6 (Slave). When I use laboratory power supply, it works without some problems. But when I use external power supply ...
