HelloWhat will happen with the IOs when MCU is put to Sleep mode (one of power modes in PWR) and register bits in RCC_AHB2LPENR for each GPIO-block are reset? When bits are reset, the peripheral clock is disabled during Sleep mode.Can the IOs still b...
Hello.I need Timer for send high speed data.To send data, i need at least 115200 fps.Can you recommend which MCU is perfect for me?
Posted on May 22, 2017 at 12:26Hello,I would like to use half precision floating variable in my project but i don't know how. I'm working on a NUCLEO-L073 board that embeds a cortex m0 STM32l073 MCU that does not have any FPU. I'm using the SW4STM32...
Hi, I am using a STM32G431KB board with STMCubeIDE. I am trying to read out the one ADC using DMA but have run into problems. As I am new to the STM32G4 and STM STMCubeIDE. I decided to follow the example of Shawn Hymel https://www.youtube.com/watch?...
Hi,I wanted to use STM32H743 with TFBGA100 package in a new project. Unfortunately this package does not provide Vref+ pin and it is internally tied to Vssa. I don't understand what is the reference source for ADCs and DAC, can I use VREFBUF in hold ...
Hi.I am using STM32H7B3LIHQ MCU, MX25LM51245GXDI00 OSPI flash, IS42S32800J-6BLI SDRAM and 24bit TFT screen. I used the schematic of the STM32H7B3I-EVAL (MB1331) board when creating the scheme. I wrote programs for FMC, OctoSPI and LTDC peripherals us...
I am experiencing processor freezes at certain points of use in our products using STM32F4.I am analyzing the cause and have a question regarding this.The processor I am using is STM32F469NI. There is a specific operation that it freezes at, and when...
I'm using Vbat as a battery voltage monitor on an STM32L431. Vref is the VDDA pin on this part, which is 3.3V. In my test case, Vbat is also connected to the same 3.3V.Vbat reads a raw count of around 1044. The internal divider is /3, so this come...
Hi i encounter this error while compiling SPI1 at ST7735.h, i dont understand as this error 'SPI_HandleTypeDef' type was generated by .ioc in main.c already and i had call this statement in ST7735.h. Could anyone kindly help? error: unknown type name...
I am using a STM32U031 part with register level configuration (no Cube libraries). The Timer should be straight forward to start in a single-shot mode but when I set the LPTIM_CR_SNGSTRT flag in the CR register, the CNT register never increments and ...
