Hi,Recently I used STM32F407 to develop firmvare code of external DAC device.In order to obtain a sinewave output from dac, I choose TIM2 to trigger interrupt.TIM2_period is configured as 167, and TIM2_prescaler is configured as 0. The sysclk is 168M...
Hello I have a Nucleo board L476RG and I would like to change the trigger mode of the comparator on the fly, the problem is that I cannot find the register responsible of this in the datasheet.I guess it's not related to the comparator but to the EXT...
Here is my code for IWDGLL_IWDG_EnableWriteAccess(IWDG); // Set the prescaler value of 8 to the IWDG LL_IWDG_SetPrescaler(IWDG, LL_IWDG_PRESCALER_8); // Specify the IWDG down-counter reload value LL_IWDG_SetReloadCounter(IWDG, 2000); ...
Posted on July 04, 2017 at 15:47Hello Team,As per STM32F769I-DISCO board schematic, I understood it should be Bypass clock source.But default cube project gives selection as Crystal ceramic. Why it is ceramic crystal?Request you to help me which one...
I've been asked to modify a device that uses a STMF103 on a J1939 CAN Bus to use ISO 11992. According to Wikipedia, this protocol is "similar to SAE J1939".Does anyone have experience with this protocol? And can the STMF103 be made to support it?Th...
I am trying to interface a Nucleo-f439zi board with an external AS6C4008-55SIN SRAM chip through an "Arduino HAT" style board I am working on. Below is my current schematic.In the chips manual, the table below is shown for using FMC to access externa...
I want to interface a Nucleo-H743ZI2 board (MB1364E) with a memory chip using STM32's FMC.In order to do this I need to free up the following 4 pins, to be used by the morpho connector:PE1, currently yellow user LED, needed for FMC_NBL1.PD8, currentl...
I have used CubeMX to configure the HAL comparator driver to trigger an interrupt on the rising edge only, however the interrupt seems to occur on both edges. I checked the EXTI registers and everything seems correct. I then thought that my voltage s...
