HiI'm using a Nucleo STM32L552 an want to use my segger JTAG; I've wired CN5 on the dev board to my JLINK (with the exception of pin 1 for VDD; I hooked that directly to the 3.3V pin in the arduino header) and I'm not able to connect my device to the...
I have successfully flashed my BluePill Board with an STM32F103 chip using the STLINK interface of a Nucleo board. Now, I have replaced the chip with an STM32F302CBT6 and am trying to flash it. However, I get the error message 'Target no device found...
i am using one side microcontroller stm32103 which have can1 protocole does this work with othere microcontoller stm32g0b1re which have FDCAN protocol.?does both communicate with each other ?will read and write the data?
I had this problem on my project, so I created a new one and added only I2C to pins Pb7 and Pb6. I set I2C from disable to I2C and I set them to "pull-up" . That's about it. And the code gets stuck in the HAL_I2C_IsDeviceReady function.I have also se...
I have a design that uses and STM32L4 series MCU. The device will be hard to physically access, but has a serial connection to the 'outside' world on UART 4. The board also has a 4 Mbit flash connected to the MCU via (bit-banged) SPI.When I need to u...
Hello,I am using a Nucleo-L073RZ board for my application. Reducing power consumption is adamant. Being so, I opted to put the MCU to sleep mode with WFE in some ocasions where some kind of delay is needed, with a reduction of HCLK (64 division). I a...
Hi, is it possible to use the external RAM as a heap. I would like to do malloc and free on it. I was able to set an huge array on it by little modifying the linkerscript, but that is not really handy because than you have to do the mem managing. Hav...
When reading from the sd card is completed, HAL_SD_RxCpltCallback is executed. But when I use the HAL_Delay() function within the callback, the rest of the code within the callback after that delay doesn't run.Any information about this issue is grea...
