Hello,I am using STM32L073V8T .I am trying wake up from standby with WKUP1 pin. It is PA0. According to techinical documents, low to high transition should wake MCU from standby. But, It doesnt work in my case. Is there any special configuration what...
As per image sub=7(not typecasted), sub1=28(typecasted). I don't understand why is sub giving wrong value I understand I have not typecasted but,each pointer variable is holding 4 byte value (i.e int type) then,typecasting must not be required isnt i...
Hi everyone,I built a custom board with STM32F429VIT with the following settings:Boot0=GND, Boot1=GNDHSE=25MHzI configured IAR project options as following:- use-Flash-loader checked;I am using IAR 8.10 with ST-Link-v2 (SWD) to develop the firmware. ...
I generated the code for the uart in dma mode in a cube. But the data does not go, and the HAL_UART_Transmit_DMA function returns HAL_BUSY.I already found a solution to the problem, just publish it.The cube generates code: MX_USART2_UART_Init (); MX_...
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...
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 ...
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...

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 ...
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 ...
