I'm developing for an STM32L0 and trying to use DMA to control the I2c peripheral Tx and Rx. I got it working so far(both Tx and Rx using DMA) but I'm stumped on the reload functionality for the I2c peripheral. Is this even possible? I looked at the ...
In DS12712 Rev 2 (STM32G473) table 13 shows PB10/11 as CAN3_TXFD/CAN3_RXFD but in table 12 CAN is not listed for these pins. Also in tab 13 sometimes it is CAN3_TX and sometimes CAN3_TXFD. Which one is valid ? Interestingly in STM32G474 tab 13 both C...
If I put port b all in analog the micro not wake up when in RTC wakeup mode (internal wakeup).Any help?Thanks in avancevoid EnterStopMode(void){ GPIO_InitTypeDef GPIO_InitStruct={0}; /* Configure all GPIO as analog to reduce current consumption on n...
Our R&D team is trying to use more memory for GUI with STM32F469I.We found the way using QuadSPI interface from the document as below.Unfortunately, the hardware already has completed with parallel Nor Flash memory, S29GL128S-16MB.Is there any other ...
My STM32F769-disco is connected via built-in st-link 2.1 to my computer. I use the bypass USART for printf(). And that works OK for output data, whereas input data stuck before they come to USART->RDR and do up the RXNE flag indicating an interrupt.H...
I am using STM32L072RB MCU.I am trying to scan the devices connected to i2c bus (i2c2 and i2c3)following is my function#define DEBUG 1 void i2c_scan(void) { uint8_t *p_data; uint16_t addr_scan = 3 ; printf("I2C3 Address : "); //scanning ...
I bought a STM32F407VET6 Microcontroller board, but I am new to Microcontroller world and I never used other Microcontrollers board before. >>> Now, I am studying Electronics Engineering. I like to start with STM32 board but I don't know where to beg...
I am trying to implement the PMBUS on STM32 processor using SMBUS/PMBUS exapnsion package. I am able to execute the read and write commands. But when I am trying to execute the READ_OR_WRITE command for read operation then I receive only FF FF in the...
