STM32 MCUs Products

Hello group. I'm working on a project with stm32-f412zg mcu board and having some trouble in configuring multiple timers using FreeRTOS for stm32-f412zg to control ws2812b led strips. I really need help in implementing it to complete the project. Any help

We are using WS2812b LEDs for output signals. We are able to configure multiple timers simultaneously but the colors are not what we trying to give signal to the WS2812b LEDs. With individual LEDs everything is fine and we are controlling it as we wa...

smartcard application transform stmf4 series to stmf7 series

Hi, I have an application on STM32F4 MCU which is based on Smartcard T =1 protocol according to ISO 7816. The app works very well. Then I choose other STM32F7 board to test this application, i faced with problems, i can read ATR from SmartCard but i ...

Is the STM32F103xG CAN bus suitable for Unpowered Node use?

Some sources state that some CAN transceivers disable the entire bus if their node is powered-down (due to low-impedance while unpowered).Some manufacturers (e.g. Texas Instruments, Microchip) explicitly state in some datasheets that their transceive...

Calculating effective ADC sample rate when using Timer Event to trigger conversion [STM32H7]

I understand the TIMER event can automatically trigger an ADC conversion that gets saved to memory (via DMA)..But if the ADC is configured to SCAN more than 1 channel, does that mean that sample rate per channel must be the TIMER rate divided by the ...

Resolved! stm32 USART2 issue

Hi , My USART1 works fine when i send a character and i recieve a character in comport , but i need to also configure USART2 ,i have configured the apb1 register and also apb2enr for the GPIOA clock enable ,i know for the fact that the clock on apb1 ...

Hi, I am doing a project with the stm32G431 micro controller with arm processor. I am trying to figure out how to write and read from flash memory correctly but I cant figure it out.

# I am willing to pay for a couple of hours help. I have some experience with micro controller but not enough to understand from the reference manual.

Resolved! G4 MCU in OnePulseMode on TIM3, how to set default (idle) value to low

I have successfully set up this timer to output one high pulse with following low state.However after finishing the period the output toggles to high until next activation.I need it to be low inbetween activations. How can this be achieved?I tried al...

Resolved! STM32F407 DMA and ADC bare metal

HiI am trying to get my ADC measurements of the interal chip temperature and data transfer to a global variable via DMA working properly. The ADC1 is triggered every second via timer 4. Configuration is stream0, channel channel 0. I do get several er...

Resolved! I cant access ADC values from DMA buffer into any other variable in while loop. DMA buffer have values in it but not going into other variable. Can anyone tell me where im wrong????
