I have generated the code (LED PB7 GPIO_OUT) by using STM32Cube Mx for MDK ARM5. While loading the code , I am getting following error.Contents mismatch at: 08001000H (Flash=00H Required=31H) !I have resolve this issue by erasing the flash using ST-L...
How can I calculate the supply current of the MCU (STM32L471) in unprogrammed state? We use it in an ultra-low power application and need to know the battery drain during production and storage.
Hi,I am working on "Deep sleep" and "Wake- Up" on STM32L476 MCU. It looks like that MCU is going in to Deep Sleep (STOP2) mode, but I am not able to "wake up" using the GPIO EXTI (GPIO External Interrupts). Following the code snippets, which I am usi...
I have two nucleo-144 boards, stm32F767zi and stm32H743zi. Both cortex-M7, pin compatible, and pretty close in AHBx (GPIO) clock, 216 vs 200 MHz.Testing TFT LCD display library, that required fast 8-bits access to the LCD data bus, I discovered that ...
I'm using STM32L152RE with FreeRtos for our project. We use RTC HAL library to handle the Calendar alarms. I'm in a strange situation where the RTC_ALARM_A does not generate an interrupt after 12 midnight. The current system is setup to generate an...
Hi, I'm working on a project in which i need to send strings through UARTMy throughput is limited because i'm working with Xbees, so i want to compress my ascii strings (that are long 1024 bytes and with simple structure because they are in csv forma...
I want to use FSMC to read external FIFO implemented in an FPGA. Since there is no mode of FSMC that can match FIFO interface exactly, so I want to use the modified synchronous multiplexed PSRAM mode. The plan is like thisA[25:16]: Ignored, don't ...
Is it possible to use Fast mode I2C on STM32F407 ? I looked everywhere for the I2CX pins GPIO but Can't find them at all.
Hi All,Can anyone suggest a STM controller supporting following features.1) 1 I2C Port.2) 4 UART Ports.3) 20 Gpios4) 1 RGB LED PinThanks,Ashok
Is there a cheap eval board e.g. Nucleo-64 with an SD-card reader. Also A cheap shield for Nucelo-64 with SD-card socket would be ok.Its for a simple logger application but I am hesitant to make a board for only a uC Sensor and SD-Card.
