Hello everybody,I need a counter with high Tacktfrequenz (eg 1 MHz) in Simulink. This allows me to turn a PIN on / off with the help of STM32 Nucleo board in μs range. In the lower model, I want to switch off the pin for 20 μs and then turn it on. Th...
Hi,today I stumbled across a problem, where I wanted to assign around 50k of RAM to FreeRTOS and I immediately got a linker error, because target ran out of RAM.I had a look at the datasheet and this says 48k RAM. I've been using a self-hacked-toget...
I am using STM32F407 on STM32F4 Discovery Board and the IDE i am using to program is Keil_v5. I am trying to transmit data using I2S communication protocol on I2S port 2. I used the System Clock Configuration tool provided by ST. The desired configur...
Hello,I would like to start a new design based on STM32H7x3.I need both CAN-FD channels. But the erratasheet from June 2018 describes a problem and the workaround is "use only one CANFD channel".Will there be a new chip version or workaround soon be...
Posted on November 15, 2017 at 10:48Hi,We are using Tianma’s - TM070RVHG01 TFT in our design with STM32F429 processor working at 168 MHz frequency. We are using EmWin Library on RTX operating system with LTDC support. We are statically storing th...
Hello,I would like to start a new design based on STM32H7x3.The STM32H7 Evalboard uses a dual voltage level translator between MCU and SD-Card. But this required some extra pins (DIR_0,DIR_1_3, CLK_FB, DIR_CMD) that I need for anothere peripheral.Cou...
The RTC wakeup interrupt uses EXTI-20. Unfortunately the HAL drivers do not properly enable the interrupt. AddingEXTI->IMR1|=(1<<20);after HAL_RTCEx_SetWakeUpTimer_IT fixes the issue
HI I have problem during the programming with HAL_I2C_Slave_Receive_IT(). At the end of the receiving without error, the HAL calls HAL_I2C_ErrorCallback(), instead of HAL_I2C_SlaveRxCpltCallback(). The error status is AF ( NAK received ). On the othe...
FolksI have set TIM2 in center-aligned PWM mode as well as a timebase ISR in which I just toggle the LED (for inspection and better understanding of the operation, otherwise to be replaced by an ADC activation, etc.). Thus, each edge of the LED (pin)...
I want to use same pin for SPI MISO and GPIO Interrupt.When I need to take data from SPI BUS then I want touse it as SPI MISO else want to use as GPIO Interrupt. How can I use same pin for both functions?
