The nucleo board has CAN rx and tx signals going out of the Zio connector, but need the CAN_H and CAN_L signals to talk to other CAN devices. Could not find an expansion board for this.Help appreciated.
I use Nucleo board (STM32L053R8) to connect SPI slave. The SPI command had been sent to slave correctly, and slave also return the expected value (0x2C). But Nucleo SPI master cannot get the return data correctly. The RXNE is raised without problem, ...
Hello, I am working on a project where I implemented various peripherals including a SAI configured in DMA mode. I have defined a 1024 samples buffer and used the Half and Full callbacks to fill it. Everything worked perfectly. However, I quickly rea...
Hi,when i use sleep mode, i have a reset problem on STM32L431CCT6 only on recent batches.I implemented the workaround described in section 2.2.5 of dm00218224-stm32l431xx-device-errata-stmicroelectronics.pdf but without success.The problem only affec...
I have an STM32F103 configured in slave mode using NSS for slave select and using DMA. I'm using 8 bit mode. When the master starts clocking the STM32F103 it always shifts out the first byte in the buffer twice. So rather than seeing 0xF0, 0xF1, 0xF2...
We discovered spurious Errors (every half a year) on reading out the GPIO Pin PC14 on a STM32F427ZIT6.The Pinis not connected on the PCB itself.Is configured as Input with PullUpAnd reads in perfectly the High state from the PullUp in 99.99% of the c...
Hello,I have a strange problem on an STM32G071. I get ADC values every 25 ms from ADC1 channel 0 to 3 without DMA as speed is no issue. Strangely when one of the canels reaches about 1.2 V the CPU sometimes goes in a hard fault lock. There is a poten...
Where generally do I find the difference described between different mcu models in the same series with same major features. For example the difference between STM32L433RCT6P and STM32L433RCT6?
Hi all.I have a motor connected to my STM32F7 board and I'm trying to generate an interrupt for every rotation. Each rotation is 2122 ticks but I keep getting an interrupt for every pulse generated from the motor encoders. My init code is:static voi...
Hi,I started now programming the STM32F767ZI MCU and do not have any experience with 32bit uController.I have to programm a project, which includes a SPI communication to an external ADC. It must be programmed with the LL library and I'd like to do t...
