Hi,I am working on STM32G474RET6 MCU in i2c slave mode. I want to make a polling mode with DMA but the problem is i don't know the receiving data's length. Every time it can be different. But 'HAL_I2C_Slave_Receive_DMA(I2C_HandleTypeDef *hi2c, uint8_...
Hi,I tried the following program:#include <Wire.h> void setup() { Wire.begin(); //creates a Wire object // set I/O pins to outputs Wire.beginTransmission(0x20); // MCP 23008 Port Expander Wire.write(0x00); //selects the IODIRA register Wire.write(0...
After receiving by master the last byte a new transmit is started (CR2.START set) from within the last ISR.RXNE ISR handler call with CR2.AUTOEND set.As a result, ISR.STOPF flag gets set and it does not get cleared setting ICF.STOPCF. Peripheral jams...
Is there a zero crossing detector inside the stm32 itself?I am using a stm32f334R8
I am using TST070CBOT-01P Along with STM32F7508-DK using RGB Interface , I have wired the jumpers with the display to the corresponding pins and everything works fine in static mode, But when transition begins then the Display shows artifacts as show...
Hi everybody,I am currently implementing a LDC3114, which has a burst mode that auto-increments the register address i want to read. The data sheet states:"For both write and read, the address pointer will auto-increment as long as the controller ack...
I would like to know for this product STM32373C-EVAL if the board has a microcontroller to program so that I can evaluate both adc and read data from both adc. and where do i get the steps from software
Board: Nucleo-f756ZG and Nucleo-F767ZIWhen i reset quickly board using reset button during execute below code, The board set RDP protection Level 1.Below code contains only rootcause. I know that is not correct usage (missing OB lock, wait for busy f...
I wanted to us CAN2 interface in my project. I started with example application ("CAN_Networking"). This example application works very well with CAN1 but when CAN2 is configured in this application it doesn't work at all. No transmission and no rece...
Should be "PRESC" rather than "PREC" I did not check but I guess this will be in other RMs too.JW
