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 ...
Both 'U5 ADCs contain the LFTRIG bit; however, I could not find in either 'U5 datasheet the Tidle value above which this bit has to be switched on.JW
Hi all, I'm trying to receive UART data from an xbee module, I've noticed the xbee is sending out the data correctly (using a logic analyzer) however the STM32L431KCU6 is not receiving this data properly and instead seems like the data is being buffe...
hi guys, I'm a desktop programmer and do not know much about micro controllers and electronics but i am very interested in making an oscilloscope which:- simple to build with well known parts and ICs- it uses bluepill as the ADC and no other ADCs- i...
