Hi, I have an STM32F407-DISC1 connected to an Raspberry PI via I2S. The clock frequency is about 3MHz. The STM is receiving as slave on I2S2 and feeding data to a ring buffer. When the ring buffer is half full transmission on I2S3 is started (as slav...
I want to make a communication between 2 microcontrollers by can protocol i put after each microcontroller a can transceiver and the problem is that we send data but i other board we don't receive it, i mean after the second receiver we don't have p...
Hi, I first worked with CAN with STM32H563 with normal mode. It worked. Later Again I tried it is not working with same code. Loop back mode is working fine. I would like to use other pins for CAN since I am using PD0 and PD1. May I know which pins...
Hi, we are evaluating STM32L4A6VGT6TR, with our new product prototype. We are only suppling one 3.3V to the MCU as it requires. We have already included discharge circuit, and we can see this 3.3V rail will be completely discharged within 0.288s. How...
Hi,I am using STM32G474RET6 controller and would like to send and receive data in classic mode. I have configured all necessary parameters using cubemx but the hard fault occured when I call this function HAL_FDCAN_AddMessageToTxFifoQ(&hfdcan1, &TxHe...
Hello,I'm trying to port the example found here: https://blog.embeddedexpert.io/?p=1680 to NUCLEO-U385RG-Q.The example in the link is for STM32F411. I've successfully tried the example.Verbatim port of the code leads to USEF being set in GPDMA_C0SR.T...
I have designed a board with a STM32H573 and a KSZ8081RNACA PHY. As soon as I enable ETH clocks the ETH_DMAMR:SWR bit gets set.Verified:1. The 50 MHz clock from the PHY is present and stable (oscilloscope) at PA12. GPIO PA1 is configured for AF11, NO...
I used the example code in RM, and room temperature is arround 31℃，the ADC value is 10644, calculated temperaure is 4127, does it means 41.27℃？what will happen if minus temperature?/* Temperature sensor calibration value address */#define TEMP130_CA...
I have an odd issue. I am setting up a timer compare channel for a 5ms delay in the future. I set the counter to 0, set the compare value to 5ms in the future. The compare interrupt does not occur, until the timer wraps all the way around and pass...
Hi all,I'm working on a very low power custom board powered by a STM32C011D6Y micro controller. I must read an ADC input routed to F1 ball (PA3, PA4, PA5 or PA6) but I'm measuring some strange power consumption related to the input voltage on the pin...
