Questions are at the endI did some measurements with nucleo stm32l053r8, stlinkv2 cut off, led3 removed power supply form v3pwr via3.3V cn6 pin4GND cn6 pin6Tools used stm cubemonitor power v1.2.1 & stlinkv3pwr multimeter (should still count as factor...
I just noticed the following:In the datasheets for the G473 and G483 the pin table and alternate function table disagree which pin has the I2C2_SMBA and I2C2_SDA function.The pin table claims PA10 is I2C2_SMBA and PA8 is I2C2_SDA. The alternate funct...
Hi All,I need some help with setting up a I2C slave on a STM32L422 chip. I have tried following the example: STM32Cube_FW_L4_V1.18.0/ NUCLEO-L412RB-P/examples/I2C_TwoBoards_ComIT but it doesn't seem to make sense to me. I realize it is not exactly th...
I was wondering if I could find any library for simulating IR signals with an STM32 microcontroller. I couldn't find any library for this purpose. While I did come across some work done by Controllers Tech on receiving IR signals from a re...
Hi,According to some of the on-the-fly firmware update documents, update is done with the following steps:- program the new firmware to Bank2- set BFB2 bit to start executing from Bank2- while in Bank2, copy the code from active Bank2 to Bank1- reset...
MCU is writing data to ext flash once every 15 minute. I have set Timer in interrupt mode with one minute callback and incrementing the flag. In main while loop, the flag is being check . Once flag has reached 15, the MCU writes data to ext flash and...
Hello All,I got Classic CAN running on the FDCAN3 module of STM32G474CE device using MXCube and other example projects for STM32G474 devices.Problem is, all these example codes have a fixed baud rate of 1Mbps. My application requires thebaud rate be...
Hello,There's a small typo in the STM32H750VB reference manual (RM0433 Rev 8).Page 545, GPIO alternate function high register (GPIOx_AFRH)Address offset: 0x2 : Should be 0x24 (confirmed by the GPIO register map).Have a nice day, thanks for the very e...
Hello, I was just wondering if there was a list in the datasheet that has a Y/N for usability with the pins on the stm32F446RE or family. I mostly keep running into the issue where I configure something on a pin and then run into a pin that is being ...
I have an STM32G473 and would like to use DMA to send a circular buffer to a set of 8 GPIOs, 6 using port A, 2 using port B. Two uint32_t arrays of equal length work as circular buffer, to be fed in the respective A or B BSRR register. Timer 7 (can p...
