Resolved! Trigger ADC1 conversion using TIM3 using registers
Hello,I am trying to have analog voltage converted every 2 seconds using the TRGO signal from TIM3. Without much success. For now, I managed to generate interrupt of TIM3 and in TIM3 Handler to use software trigger for ADC. Here is the code:TIM3:void...
[SOLVED] Issue with custom External Loader for IS25LP256D on STM32F746 - update to V2.5.0 & deinit qspi in Init()
I've made a custom external loader for IS25LP256D on STM32F746. It works well in general except for one problem. Verify doesn't stop when "Verify Programming" is checked. Memory-mapped mode works well, which means reading is good. Erase() and Write()...
Resolved! Sample project using STM32H743 and ISSI IS25LP256D (QSPI chip)
Hi Folks,I'm working with a custom board using STM32H743 and wanting to work with a ISSI IS256P256D QSPI chip.I tried using STMCubeMX to create a sample project. when I start the project using the "Start my project from MCU" it creates files but th...
External loader for external SDRAM
HelloI want to download my code in the external SDRAM connected to a STM32H743 for debugging purpose. I use the STM32CubeIDE, I wrote an external loader .stldr to configure the FMC.In the debugger tab, I selected the external Loader but it fails to l...
STM32G option bytes modification fails in DFU mode
I'm working with a host PC running a C++ Visual Studio project which is running some API calls to implement the DFU protocol. Those API are exposed by some DLL and LIB file available with STM32CubeProgrammer. The host PC is connected via a USB cable...
Resolved! STM32 PLL Configuration Triggers WWDG Infinite Loop, PLL Config Problem CMSIS
STM32F746-Disco, Win 10, CubeIDE 1.8.0, CMSIS-only (no HAL), C.I've decided to change the clock of my MCU from HSI 16MHz to full 216MHz with PLL. I've setup the correct values for PLL parameters, but whenever I actually switch system clock to PLL, th...
How Can I measure the input frequency by Timer Input Capture?
Hi I measure the frequency from sensor using the Timer Input Capture mode. I set the timer can read minimum 1Hz.72M / 7200/65535 = 0.15HzThis is my code. void HAL_TIM_IC_CaptureCallback(TIM_HandleTypeDef *htim) { HAL_GPIO_WritePin(LED_PORT, IN_LED_...
