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?
#error "Define according the used Cortex core ARM_MATH_CM7, ARM_MATH_CM4, ARM_MATH_CM3, ARM_MATH_CM0PLUS or ARM_MATH_CM0"I was using below boards and generated the source code by MX. But above error doesn't understand me. Target: STM32F302R8TxExtensi...
My STMF103 user interface processor needs two modes of operation. One needs to be as fast as possible updating the TFT or TX/RX data, and the other can be slower when it is just monitoring keys and switches. To save power I was thus thinking of us...
We are using the STM32L476VG Discovery Board and are trying to use the SPI 1 interface. I generated the code through CubeMX with pins PA5, PE13, PE14, PE15. After the code was generated I tried placing this example code into the while loop: HAL_G...
In my debugger settings I got there is some SWO frequency difference means before 2 or 3 days its frequency value is 10Mhz but now it is only 2Mhz and from last days I have getting some errors. So plz tell me that such errors are coming due to this ...
