We have an existing bare metal environment using STM32F446ZET6 and 8MB of SRAM which works fine, hundreds of examples in the field.A new smaller version of this platform uses PSRAM, namely IS66WVC4M16ECLL.We are getting memory corruption issues we ca...
Greetings,I am working on a project where a STM32H743 nucleo board and use of 16 ADC inputs are involved.Obviously, these analog inputs are used once a time; read the value via polling mechanism and configure the next input... configure the ADC chann...
HiI am using the Stm32H743 Nucleo Board.I followed the app note to use the DFSDM(https://www.st.com/content/ccc/resource/technical/document/application_note/group0/7d/62/3d/ad/24/57/47/78/DM00380469/files/DM00380469.pdf/jcr:content/translations/en.DM...
I hope the title tells it but F746 was out of stock in a couple of European stockists and H750 was in stock and also cheaper. Both in LQFP100. I wonder am I lucky or do I have to make a new board? If buggy forum permits, that is.
I have the following EXTI9_5 handler: (yes, with HAL)void EXTI9_5_IRQHandler(void) { if (__HAL_GPIO_EXTI_GET_IT(GPIO_PIN_6) != 0) { __HAL_GPIO_EXTI_CLEAR_IT(GPIO_PIN_6); return; } if (__HAL_GPIO_EXTI_GET_IT(GPIO_PIN_5) !...
I'm currently in the process of compiling example code from our supplier for an e-ink display. The issue however is it uses functions that predate HAL from what I can tell. While some things are simply renaming to uppercase, some other things are unk...
Hello,I am working with STM32F407 evaluation board. I want to use i2c as a slave on it.My master device is siliconlab micro-controller (mighty gecko).What slave address i should use for sending data for STM32?As master needs slave address to send dat...
I'm trying to use ADC in stm32g030j6m6 to measure DC voltage.but, whenever I try to make experiences. I found out that under 3V, The accuracy of adc isn't great. It has a 10% error.I attached source code that I used in my experience and the table th...
External oscillator: MC-146 32.7780KA-A0Load capacitors used: CL_1 = CL_2 = 8pFWith Drive Level of Low the application works. I would like to obtain better understanding of how the G_m_crit_max is connected to the CL. I've had a look at AN2867 - Osc...
hello, i have a input capture who lost edge when i plug USB.when the USB cable is not plug or unpluged works perfectly.i have a toggle led in the capture callback.when i plug the frequency of the led is unstable.when i unlug cable, toggle frequency ...
