Regarding the problem that CTSIZE becomes 0x01 after SPI communication is completed,In our program, SPI-SR-CTSIZE becomes 0x01 after SPI communication is completed.In that state, if we try to perform the next SPI communication, a timeout error occurs...
[This is a reconstruction of a thread I've started on Mar 26, 2017, but got lost in the two forum software transitions since then.]Reports in IWDG short period (125 us) problem and STM32F407 : IWDG and erase flash sector indicate that the IWDG does...
Dear all, I'm using stm32f412ret6 MCU in my custom made board. The code used is as below. The HAL_CAN_Start function returns HAL_ERROR. when debugged the issue is timeout with in the HAL_CAN_Start function. I don't understand if I'm going wrong any...
I am using an STM32G473MEY3 MCU. I am looking in the reference manual in the FLASH section, but I am not sure if this is a cateogry 2, cateogry 3, or category 4 device. I am thinking category 3. Any ideas?
I am trying to use the LSI as the clock source on the STM32 G0B1KEU6. It doesn't work, and as soon as I select the LSI in the MUX on the clock tree, my code stops working. To ensure there are no other sources of error, I used the exact same code but ...
Hello, I am attempting to have a two stm32 nucleo boards communicate by sending and receiving can messages. My goal is to have the PA5 LED of the STM32 f446re blink when a can message is received. I know that the canbus must be configured to classic...
Hi,in a setup on STM32H725 where TIM1 ETR triggers several DMA activities, I observe an effect while debugging that I would rather like to avoid:Looking at the NDTR of the three DMA, it seems that one extra ADC run (or at least the related DMA transf...
Hello everyone,I'm currently using the STM32F401CCU6 in my project, but it's proving to be oversized for my application, both in terms of physical package and power requirements. I'm hoping to switch to a smaller STM32 microcontroller that maintains ...
Hi all,I am trying to activate SDADC on my custom designed board to measure a couple of analog voltages. I am trying to measure 5-channels in injected continuous mode. Offset = 0, Gain = 1, Single-Ended Offset Mode. See the CUBE settings below :In th...
Hello!This is the first time im using NOR Flash so bear with me :)Question #1I screwed up and forgot to add a pullup for the open drain ready/busy NOR output.So i've tried the ghetto approach of using the internal pullup of the STM32 as "busy wait" b...
