Hi,I am unable to flash or erase two of my STM32G030F6P6 boards. The issue started after I tried to configure the PA14 pin as GPIO_EXTI14 in CubeMX. (on two boards)After flashing the binary I was not able flash the MCU anymore. I get the error "Error...
I am attempting to reconfigure Pin 8 (datasheet default assignments are PB6/PA14-BOOT0/PC15-OSCX_OUT) from PA14-BOOT0 to PB6 GPIO Output Open Drain (GPIO_MODE_OUTPUT_OD) a short time after start-up.My current attempt (code below) does not accomplish ...
Hi everyone,I’m working with an STM32L5 USART and trying to clarify a point about parity vs. MSB-first transmission.From the reference manual (USART parity control / frame formats), when parity is enabled the frame formats are shown as:M=00, PCE=1: S...
Hey. I'm trying to use my H7's usb interface and i've currently set it up as a cdc device.What i'm trying to implement though is the following. The stm is supposed to create a virtual connection with either a python app or a tera term terminal.Is the...
Experimenting with STM32F427 and STM32F446 I found out, that the RCC_CR.HSEBYP bit is *not* reset by Software reset. It is reset only by NRST and Power-On reset.While applications where this could lead to problems (i.e. where HSE clock source is chan...
CNC material affects EMI, thermal dissipation, and grounding.I found this CNC material selection guide helpful:https://www.justway.com/blog/CNC_Machining/How_to_Choose_the_Perfect_Material_for_CNC_Machining_A_Comprehensive_Guide_fb9e953e.htmlHow do y...
I'm reading RM0492 Rev 3 about I2C's controller transmitter. The original words on the page of 1185 areWhen RELOAD = 0 and the number of data bytes defined in NBYTES[7:0] is transferred: • In automatic end mode (AUTOEND = 1), a STOP condition is auto...
Hello, In the MCU datasheet, there is a table on page 200: Table 72. Typical dynamic current consumption of peripherals.What is the meaning of the current writing in the peripherals on stop modes, since in this mode, all clocks in the core domain are...
Hello,I am using STM32H750VBT6 to perform microSD card write operations. After a number of writes, the CPU sometimes resets during a write operation. At the same time, the Vcore (1.13V) rail shows a voltage drop. The issue is random, but the higher t...
One of the AF options on SPI1 is to use the SWD debug pins PB3-PB5.How can this be used in reality?Pretty obviously you can't do SWD breakpoints when SPI1 is thus mapped!But assuming no SWD debugging is needed, and you use SWD just to program the FLA...
