Hello, I have a STM32F411 and I am ready using the SDIO port, I would like to connect 2 SDCARD to the SDIO port and be able to switch from one to another like using a CS Chip select GPIO. Is it possible ? how would I do that ? Thanks Vincent
Hi,One of our project is using the STM32U575 and we use the ADCs analog watchdog feature of the CPU. At the beginning of the project, we did not used the ADC oversampling, but for stability and reliability purpose, we have turned on the ADC oversampl...
Hiin my project I have enabled FreeRTOS, so the NVIC prios 0-4 are reserved for FreeRTOS.I need to generate a highly accurate 1 sec timer interrupt.Is it correct that FreeRTOS interrupts might delay my (cortex) timer intterupt handlers to be called?I...
Hi,I need to synchronize my UART transmission with a timer using DMA. I don't want CPU intervention in fixed data transmission. My data and size is fixed. I need to continuously transmit the packet every 5ms.kindly suggest!
Hello I have project where is used a STM32F103RGT6 (1Mbit flash and 96 kb SRAM) in LQFP-64 package.Is there a replacement for this MCU with more SRAM and faster clock? I found a STM32F415RGT6 with the same package, bigger SRAM size 192 kb versus 96 k...
I currently have ADC1 working with DMA at 14 MHz so my sample rate is 1 Msps I believe. I want to double my sample rate, so I thought I could use both ADCs with DMA and interleave the buffer data. My issue is that when I am trying to configure ADC2, ...
Hello,I am trying to integrate internet connectivity on the STM32F407 using an LTE modem via the PPPoS protocol(UART). I've successfully established a PPPoS (iusing Ethernet LWIP) connection and obtained the modem IP on the STM32F407. Could you pleas...
Hi,I am designing a system that will be using an STM32F411 microcontroller as the hardware application processor, the system will also have onboard a Single board computer module running Linux. While the application processor will take care of the m...
Hello, I am using NUCLEO F767 microcontroller. i want to receive data using CAN. I am using CAN2. pins PB12 Rx and PB13 TX. I have tried bunch of things but i am unable to receive data. So, please help me regarding this Code : int main(void) {...
I have come across a rather weird problem and would like to get some direction.I am using STM32F756 nucleo board. I set ADC1 to trigger by TIM1 (the complete project uses some other peripherals). TIM1 is set as PWM generation. All these are set using...
